<span style="font-family: Times, "Times New Roman", serif;">“Nós ainda não temos informação científica validada por entidades independentes que nos permita responder com rigor sobre se são mais ou menos nocivos [do que o tabaco]. Uma coisa é certa: são nocivos para a saúde, mas o grau de nocividade não é totalmente conhecido pois eles ainda estão no mercado há pouco tempo, sobretudo o tabaco aquecido”, disse Emília Nunes à Lusa.</span></div>
<div class="text-paragraph" style="-webkit-text-stroke-width: 0px; box-sizing: border-box; color: #333333; font-size: 1.12rem; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 1.3em; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">Na data em que se assinala o Dia do Não Fumador, a responsável pelo Programa Nacional para a Prevenção e Controlo do Tabagismo (PNPCT) defende que o ideal é “o risco zero” e recorda: “Relativamente aos cigarros eletrónicos, estão agora a aparecer mortes, sobretudo quando são consumidos com determinados aromas ou misturas com derivados de canábis”.</span></div>
<div class="text-paragraph" style="-webkit-text-stroke-width: 0px; box-sizing: border-box; color: #333333; font-size: 1.12rem; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 1.3em; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">“No fundo estamos a passar para um produto que também não sabemos se afinal de contas vai ou não vai mesmo diminuir o risco. Não está demonstrado e não sabemos a médio prazo os ganhos ou não”, afirmou.</span></div>
<div class="text-paragraph" style="-webkit-text-stroke-width: 0px; box-sizing: border-box; color: #333333; font-size: 1.12rem; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 1.3em; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">Emília Nunes explica que a legislação “proíbe totalmente as campanhas feitas pela indú<span style="-webkit-text-stroke-width: 0px; background-color: white; color: #333333; display: inline !important; float: none; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">stria” e diz que as autoridades precisam de maior capacidade da fiscalização.</span></span></div>
<div class="text-paragraph" style="-webkit-text-stroke-width: 0px; box-sizing: border-box; color: #333333; font-size: 1.12rem; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 1.3em; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">“A fiscalização está a cargo de várias entidades, da Direção-Geral do Consumidor, da Alta Autoridade para a Comunicação Social, da Autoridade de Segurança das Atividades Económicas, portanto, precisaríamos também de ter mais capacidade de intervir nessa nossa dimensão”, afirmou.</span></div>
<div class="text-paragraph" style="-webkit-text-stroke-width: 0px; box-sizing: border-box; color: #333333; font-size: 1.12rem; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 1.3em; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">O relatório de 2019 do PNPCT, a que a Lusa teve acesso, reconhece que os jovens têm menos noção do grau de dependência, pois julgam que é fácil deixar e isso torna-os mais vulneráveis a experimentar.</span></div>
<div class="text-paragraph" style="-webkit-text-stroke-width: 0px; box-sizing: border-box; color: #333333; font-size: 1.12rem; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 1.3em; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">Os dados recolhidos no âmbito do estudo “Comportamentos aditivos aos 18 anos: inquérito aos jovens participantes no Dia da Defesa Nacional”, em 2018 - citados no relatório do PNPCT, indicam que 60,1% dos jovens de ambos os sexos disseram já ter consumido tabaco; 48,8% nos últimos 12 meses e 38,3% nos últimos 30 dias.</span></div>
<div class="text-paragraph" style="-webkit-text-stroke-width: 0px; box-sizing: border-box; color: #333333; font-size: 1.12rem; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 1.3em; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">O relatório do PNPCT diz também que “continuar a fumar ao longo da vida adulta, compromete a saúde e longevidade”.</span></div>
<div class="text-paragraph" style="-webkit-text-stroke-width: 0px; box-sizing: border-box; color: #333333; font-size: 1.12rem; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 1.3em; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">“Se não se conseguir impedir que os jovens comecem a fumar, as próximas gerações continuarão a suportar um pesado fardo, não só em termos de doença, incapacidade e mortalidade prematura, mas também em gastos em tratamentos e serviços <scroll-bookmark class="sb-count" data-word-count="400" style="box-sizing: border-box;">de</scroll-bookmark> saúde”, sublinha o relatório.</span></div>
<div class="text-paragraph" style="-webkit-text-stroke-width: 0px; box-sizing: border-box; color: #333333; font-size: 1.12rem; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 1.3em; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">O documento alerta também para a necessidade de uma comunidade científica “ativa e isenta de conflitos de interesses”, que investigue e produza “a base de comprovação e evidência necessárias à tomada de decisão política, legislativa e técnica, em favor da promoção da saúde pública”.</span></div>
<div class="text-paragraph" style="-webkit-text-stroke-width: 0px; box-sizing: border-box; color: #333333; font-size: 1.12rem; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 1.3em; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">A propósito dos estudos que indicam que as campanhas da industria estão a direcionar-se cada vez mais para os jovens, o relatório sugere que se avance com o protocolo entre a Direção-Geral da Saúde e a Direção-Geral de Educação para a prevenção do tabagismo em meio escolar e reforçar a colaboração com o Instituto Português da Juventude e com as Sociedades Científicas e Organizações Não Governamentais (ONG) nesta área.</span></div>
<div class="text-paragraph" style="-webkit-text-stroke-width: 0px; box-sizing: border-box; color: #333333; font-size: 1.12rem; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 1.3em; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">Questionada sobre se os novos produtos de tabaco poderiam ser uma boa estratégia para deixar de fumar, Emília Nunes responde: “Na verdade, até podem ter um efeito perverso que é diminuir a perceção de risco e muitas pessoas fumadoras que poderiam querer deixar de fumar passam para estes produtos na convicção de que é igual a deixar de fumar”.</span></div>
<div class="text-paragraph" style="-webkit-text-stroke-width: 0px; box-sizing: border-box; color: #333333; font-size: 1.12rem; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 1.3em; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">“Isto é uma ideia que às vezes a indústria também transmitiu: que fumar aquele produto tem menos risco e, portanto, é equivalente a deixar de fumar, quando na verdade não há confirmação de que assim seja”, insistiu.</span></div>
<div class="text-paragraph" style="-webkit-text-stroke-width: 0px; box-sizing: border-box; color: #333333; font-size: 1.12rem; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 1.3em; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">“Há aqui um ponto comum: todos eles, tendo nicotina, provocam dependência e, portanto, vão colocar os consumidores numa situação de perda de liberdade relativamente ao consumo”, acrescentou a responsável, sublinhando: “A ideia que queremos passar é que as pessoas devem mesmo deixar de fumar”.</span></div>
<div class="text-paragraph" style="-webkit-text-stroke-width: 0px; box-sizing: border-box; color: #333333; font-size: 1.12rem; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 1.3em; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">Por outro lado, acrescentou, também importa que os próprios pais sensibilizem as crianças desde cedo para a perigosidade destes produtos, não dando o mau exemplo ao fumar junto deles”.</span></div>
<div class="text-paragraph" style="-webkit-text-stroke-width: 0px; box-sizing: border-box; color: #333333; font-size: 1.12rem; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 1.3em; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">

<span style="font-family: Times, "Times New Roman", serif;">A nicotina é a única substância do cigarro que causa dependência física e, a nível psicológico, está muitas das vezes também associada às emoções subjacentes ao ato de fumar. Quando deixa de fumar, o indivíduo não só sente falta da ação da nicotina como, psicologicamente, fica carente de um conjunto de emoções associadas ao tabagismo. Na sequência disso, o organismo procura uma compensação com outros hábitos.</span></div>
<div style="-webkit-text-stroke-width: 0px; box-sizing: border-box; color: #333333; font-size: 1.12rem; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 1.3em; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">Hábitos esses que acabam por promover o aumento de peso. Estes não são, contudo, os únicos fatores que podem explicar o facto dos ex-fumadores terem tendência para engordar. Num programa de cessação tabágica, em média, um ex-fumador tende a engordar três a quatro quilos. Para este facto convergem diversas causas:</span></div>

<span style="font-family: Times, "Times New Roman", serif;">Célia Francisco, psicóloga e especialista em gestão de peso, habituada a lidar com estes casos, explica que «quando deixam de fumar, habitualmente, os indivíduos tendem a compensar a ausência do cigarro com a ingestão de comida para lidar com as suas emoções e para substituir uma fonte de prazer (que deixou de existir)», sublinha. Com o consumo exagerado de calorias, naturalmente, dá-se o aumento de peso.</span></div>
<div style="-webkit-text-stroke-width: 0px; box-sizing: border-box; color: #333333; font-size: 1.12rem; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 1.3em; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">

<div style="box-sizing: border-box; font-size: 1.12rem; margin-bottom: 1.3em; margin-top: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">«Quando se deixa de fumar, ocorre uma lentificação fisiológica do metabolismo. Se o indivíduo não compensar a mudança que ocorre com um plano alimentar equilibrado e controlado em termos calóricos e a prática de exercício físico, é normal que aumente de peso. No entanto, engordar não é uma condição obrigatória», afirma Célia Francisco. Esta característica depende do autocontrolo e das estratégias adotadas ao nível do estilo de vida.</span></div>
<div style="box-sizing: border-box; font-size: 1.12rem; margin-bottom: 1.3em; margin-top: 0px;">

<div style="box-sizing: border-box; font-size: 1.12rem; margin-bottom: 1.3em; margin-top: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">A nicotina é também um inibidor do apetite e, quando se deixa de fumar, esse travão desaparece, ficando também os sentidos do paladar e do olfato mais apurados. «O apetite aumenta e a comida começa a saber melhor. A pessoa começa também a repetir o prato, algo que não fazia antes», salienta Susana Simões, pneumologista.</span></div>

<div style="box-sizing: border-box; font-size: 1.12rem; margin-bottom: 1.3em; margin-top: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">Num fumador, os níveis de açúcar são mais elevados do que os de um não fumador, o que conduz a uma maior apetência por doces quando se deixa de fumar.</span></div>

<span style="font-family: Times, "Times New Roman", serif;">Segundo a American Cancer Association (ACA), «o aumento de peso que ocorre quando se deixa de fumar é, geralmente, muito baixo». «É mais perigoso continuar a fumar do que aumentar um pouco de peso» e há sempre estratégias simples que ajudam a controlar a acumulação de quilos a mais.</span></div>
<div class="content" style="-webkit-text-stroke-width: 0px; box-sizing: border-box; color: #333333; font-size: 1.12rem; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 1.3em; margin-top: 0px; orphans: 2; position: relative; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">

<span style="font-family: Times, "Times New Roman", serif;">Mais do que controlar o peso, «controle a sua vida», sugere Célia Francisco. Segundo a psicóloga, «para evitar o aumento de peso, é fundamental estabelecer previamente um plano de emergência ao nível da alimentação, do stresse e do exercício. É essencial que se mentalize que terá de colocar em prática e implementar um estilo de vida completamente renovado. As mudanças deverão ser totais e não somente uma parte do problema», defende.</span></div>

<span style="font-family: Times, "Times New Roman", serif;">A pneumologista Susana Simões aconselha os ex-fumadores a manterem uma alimentação saudável, a não repetirem as refeições e a evitarem a ingestão de doces, resistindo às sobremesas. Os doces não só engordam como podem acionar a vontade de fumar. Já os alimentos picantes, embora não sejam hipercalóricos, <scroll-bookmark class="sb-count" data-word-count="800" style="box-sizing: border-box;">também</scroll-bookmark> promovem a vontade de fumar. Limite ainda o consumo de alimentos ricos em gorduras.</span></div>
<div class="content" style="-webkit-text-stroke-width: 0px; box-sizing: border-box; color: #333333; font-size: 1.12rem; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 1.3em; margin-top: 0px; orphans: 2; position: relative; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">

<span style="font-family: Times, "Times New Roman", serif;">Isto não significa ir diariamente ao ginásio, mas apenas que deverá incorporar mais atividade física no seu dia a dia para ativar o seu metabolismo e queimar as calorias a mais. Experimente «caminhar meia hora a pé todos os dias», sugere Susana Simões.</span></div>

<span style="font-family: Times, "Times New Roman", serif;">Faça cinco a seis refeições diárias. Segundo a ACA, esta estratégia «mantém os níveis de açúcar no sangue e de energia equilibrados e ajuda a evitar a vontade de fumar», assegura a especialista.</span></div>

<span style="font-family: Times, "Times New Roman", serif;">As refeições principais devem incluir «sempre alimentos com proteínas e de origem vegetal (fruta e/ou legumes)», recomenda Célia Francisco.

As explicações de um médicoRui Alves<br />

Hoje é o Dia Mundial do Não Fumador.</span></span></div>

<span style="font-family: "times" , "times new roman" , serif;">O consumo de tabaco induz dependência física e psíquica na maioria dos consumidores, afeta todo o organismo humano e é a primeira causa de morbilidade e mortalidade evitáveis, os fumadores apresentam piores indicadores de saúde, do que os não fumadores e uma esperança de vida menor, em média dez anos.</span></div>

<span style="font-family: "times" , "times new roman" , serif;">Estima-se que cerca metade dos fumadores regulares morre em resultado do consumo de tabaco, 1 em cada 4 entre os 25 e os 59 anos de idade.</span></div>
<div style="-webkit-text-stroke-width: 0px; box-sizing: border-box; color: #333333; font-size: 1.12rem; font-variant: normal; letter-spacing: normal; margin-bottom: 1.3em; margin-top: 0px; orphans: 2; text-align: justify; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">

O ato de acender um cigarro está relacionado com situações do dia a dia como comer ou beber café. A ausência de nicotina provoca ansiedade, irritabilidade, nervosismo, cefaleias, insónias, dificuldade de concentração e desejo imperioso de fumar.</span></span><b></b><i></i><u></u><sub></sub><sup></sup><strike></strike></div>

<span style="font-family: "times" , "times new roman" , serif;">A maioria dos fumadores gostariam de deixar de fumar e tentam a cessação tabágica entre seis e nove vezes durante a sua vida, o que corresponde a cerca de 80%. Sem ajuda, os que estão sem fumar ao fim de um ano não ultrapassam os 7% e com ajuda médica este valor passa para 25% a 35%. Os fatores fundamentais para a cessação tabágica são três: motivação do fumador, aconselhamento e utilização de fármacos.</span></div>
<div class="content" style="-webkit-text-stroke-width: 0px; box-sizing: border-box; color: #333333; font-size: 1.12rem; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 1.3em; margin-top: 0px; orphans: 2; position: relative; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: "times" , "times new roman" , serif;">Para deixar a dependência contamos com a motivação e a mudança de hábitos do fumador, pedimos-lhe que marque uma data para parar de fumar, partilhando a decisão com a família e amigos e que prepare esse dia. Pedimos ainda que mude alguns comportamentos, fazer exercício, dieta mais saudável, menos sal e gordura, menos álcool e mais água. As taxas de sucesso a longo prazo são mais elevadas com farmacoterapia e apoio psicológico. O recurso a terapêutica farmacológica duplica as possibilidades de sucesso.</span></div>

<span style="font-family: "times" , "times new roman" , serif;">A intervenção de apoio intensivo deve ser oferecida aos fumadores que encaram seriamente a possibilidade de deixar de fumar nos próximos 30 dias, aos que fumam o primeiro cigarro até 30 minutos depois de acordar, aos que fumam mais de 20 cigarros por dia, aos fumadores com recaídas ou que apresentam síndroma de privação intenso. Igualmente devem ser encaminhados para <scroll-bookmark class="sb-count" data-word-count="400" style="box-sizing: border-box;">as</scroll-bookmark> consultas de cessação tabágica os fumadores com patologias relacionadas com o tabaco como a DPOC, cancro e doença cardiovascular, fumadores com outros comportamentos aditivos e fumadoras grávidas.</span></div>

<span style="font-family: "times" , "times new roman" , serif;">O êxito na cessação tabágica é maior nos homens, nas pessoas com nível de escolaridade mais elevada e nos que conseguiram parar em tentativas anteriores prolongadas.</span></div>

<span style="font-family: "times" , "times new roman" , serif;">A farmacoterapia para a dependência da nicotina tem como objetivos diminuir os sintomas de privação, permitindo aprender a viver sem fumar e fornecer os efeitos que o fumador retirava do tabaco: concentração, temperamento menos irritável, controlo do peso, etc.</span></div>

O estudo EAGLE publicado em 2016 e envolvendo mais de 8000 fumadores, mostrou dados muito interessantes: a vareniclina revelou-se mais eficaz que o placebo. Não houve aumento significativo de efeitos secundários atribuíveis à vareniclina relativamente aos substitutos da nicotina e ao placebo.</span></span></div>

<span style="font-family: "times" , "times new roman" , serif;">A recaída faz parte do processo terapêutico de cessação tabágica e é frequente, deve ser prevenida, identificando situações de alto risco, treinando a abordagem para lidar com as mesmas.</span></div>

<span style="font-family: Times, "Times New Roman", serif;">A osteoporose afeta a densidade e qualidade dos ossos e é considerada uma doença silenciosa. Esta doença é responsável por 40 mil fraturas ósseas por ano em Portugal, sendo as mais comuns da anca, da coluna e do punho.

<span style="font-family: Times, "Times New Roman", serif;">O Dia Mundial do Inseto Comestível assinala-se na quarta-feira e a associação do setor não tem dúvidas que ele vai fazer parte da alimentação do futuro. Mas diz que no presente, por causa de leis da União Europeia, a vida não está fácil para investidores na maior parte dos países.</span></div>
<div class="text-paragraph" style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">A Portugal Insect – Associação Portuguesa de Produtores e Transformadores de Insetos vai assinalar a efeméride no próximo sábado na Universidade Nova de Carcavelos, arredores de Lisboa, com uma conferência sobre temas como insetos na alimentação humana, enquadramento legal, aplicações culinárias ou insetos nas ementas das escolas.</span></div>
<div class="text-paragraph" style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">No final da conferência vai haver uma sessão de degustação, a título excecional porque ainda é proibido o comércio de insetos para alimentação, como lembrou à Lusa o presidente da Portugal Insect, Rui Nunes</span>.</div>
<div class="text-paragraph" style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">A propósito da iniciativa desta semana o responsável afirmou que em Portugal já existem há vários anos alguns produtores de insetos, juntos na associação que foi criada no ano passado, e lembrou também que o inseto como fonte de proteínas já é um tema na agenda da FAO – Organização das Nações Unida para a Alimentação e Agricultura desde 2013.</span></div>
<div class="text-paragraph" style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">Em maio de 2013 a FAO defendeu num relatório que os insetos consumidos anualmente por 2.000 milhões de pessoas são uma alternativa promissora à produção convencional de carne, com vantagens para a saúde e para o ambiente.</span></div>
<div class="text-paragraph" style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">Num planeta com nove mil milhões de pessoas em 2050, “onde vamos arranjar fontes proteicas?”, questiona agora Rui Nunes, acrescentando que dentro do milhão de espécies de insetos há duas mil espécies “comprovadamente comestíveis”, que já são consumidas por milhões de pessoas, embora os europeus ainda tenham “alguma relutância”.</span></div>
<div class="text-paragraph" style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">Em Portugal os produtores estão a investir, para alimentação humana e animal, em algumas espécies de grilos, no tenebrião, a chamada larva da farinha, e mesmo gafanhotos.</span></div>
<div class="text-paragraph" style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">Por uma questão de segurança alimentar, explica Rui Nunes, a produção tem de ser controlada e em cativeiro, de forma segura, O que acontece, diz, é que atualmente, por força de um regulamento europeu (2015/2283), não é permitido esse tipo de comercialização.</span></div>
<div class="text-paragraph" style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">“O que está em causa é que <scroll-bookmark class="sb-count" data-word-count="400" style="box-sizing: border-box;">para</scroll-bookmark> os insetos poderem ser consumidos tem de se apresentar dossiers de segurança alimentar. E ainda nada está aprovado”, explica Rui Nunes.</span></div>
<div class="text-paragraph" style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">Mas o regulamento permite que países que antes da publicação já produziam insetos o possam continuar a fazer. E “hoje temos países onde é permitido comer insetos e há outra Europa onde é proibido porque ainda não estão aprovados os dossiers de segurança alimentar. Há uma Europa que permite produção e consumo e há uma Europa que não”, lamenta.</span></div>
<div class="text-paragraph" style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">Na prática, diz na entrevista à Lusa, a Holanda, a Finlândia, o Reino Unido, a Dinamarca, a Bélgica e a Áustria podem produzir e consumir insetos, os restantes países não. E a Portugal Insect não se sente por isso representada pela associação europeia do setor (International Platform of Insects for Food and Feed – IPIFF), preferindo trabalhar, a nível interno, com as autoridades portuguesas.</span></div>

<span style="font-family: Times, "Times New Roman", serif;">Atualmente, alimentos a partir de insetos não são permitidos junto da população nem sequer podem servir para alimentar animais, exceto para aquacultura.</span></div>
<div class="text-paragraph" style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">O presidente da associação explica que a proibição de rações com fontes proteicas a partir de animais existe desde a “doença das vacas loucas”, uma doença que afeta o gado descoberta nos anos 1980 e que será provocada por um agente infeccioso chamado prião e que supostamente é constituído apenas por proteína.</span></div>
<div class="text-paragraph" style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">Rui Nunes, fundador da empresa Entogreen, explica que na altura se proibiu que os animais fossem alimentados por outros animais, e defende que a proibição seja levantada para os porcos e as aves.</span></div>
<div class="text-paragraph" style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">E que naturalmente os insetos possam ser comercializados e consumidos pela população, porque é um produto “normal” e “não é estranho nem esquisito”.</span></div>
<div class="text-paragraph" style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">José Guimarães, vice-presidente da direção da Portugal Insect e fundador da empresa Nutrix, diz também à Lusa que até à autorização de comercialização se projeta e se investiga, e salienta que além da questão de ser preciso alimentar a população mundial em crescimento a produção e consumo de insetos tem um lado muito importante “na questão dos impactos ambientais”.</span></div>
<div class="text-paragraph" style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">Quer no consumo de água, na quantidade de alimentos, no espaço necessário, e na produção de gases com efeito de estufa, o uso de insetos como fonte de proteína tem um impacto “significativamente inferior” quando comparado com outras produções tradicionais.</span></div>
<div class="text-paragraph" style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">Por tudo isto Rui Nunes diz que o que se espera é que no próximo ano todos os entraves sejam desbloqueados a nível europeu ou que uma decisão política em Portugal abras portas a um setor <scroll-bookmark class="sb-count" data-word-count="800" style="box-sizing: border-box;">“em</scroll-bookmark> franco crescimento”, que vai ficar por conta de seis países se nada for feito.</span></div>
<div class="text-paragraph" style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">E nesses países a população come insetos? Rui Nunes diz que a aceitação é gradual, que é “um produto de nicho, que está a crescer".</span></div>
<div class="text-paragraph" style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">Na associação, a pensar numa maior aceitação do consumidor, discute-se a melhor forma de apresentar os insetos, se desfeitos numa farinha ou numa barra, se inteiros, “ao natural”.</span></div>
<div class="text-paragraph" style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">Para já, e porque nem sequer podem vender, no dia 26, na iniciativa de Carcavelos, vão “dar a provar” quer insetos processados, em forma de bolachas, quer inteiros, como vieram ao mundo. E o “chef” de cozinha Chakall também se associou ao projeto, com sobremesas e entradas de insetos.</span></div>
<div class="text-paragraph" style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">José Guimarães está otimista. A alimentação transforma-se ao longo dos tempos. “Há 20 anos, quando o sushi surgiu, as pessoas reagiram de forma adversa. Hoje nem seque é tema de conversa”.</span></div>
<div class="text-paragraph" style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="-webkit-text-stroke-width: 0px; background-color: transparent; color: #333333; display: inline !important; float: none; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: left; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;"><span style="font-family: Times, "Times New Roman", serif;">É José Guimarães quem o diz. E recua um pouco mais no tempo com outro exemplo. Nos Estados Unidos, há dois séculos, os prisioneiros eram alimentados com lagosta. E reclamavam por isso.</span></span></div>

<span style="font-family: Times, "Times New Roman", serif;">É um ser de uma só célula mas tem em si mesmo 720 sexos e, se cortado ao meio, capacidade de se regenerar em cerca de dois minutos. É uma espécie de fungo - ou bolor - e apesar de não ter boca, olhos ou cérebro consegue resolver problemas simples.</span></div>
<div style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">O Blob, ou la Blob como é chamado pelos franceses, está desde ontem, dia 19 de outubro exposto no Parc Zoologique, em Paris. O seu nome científico é <em style="box-sizing: border-box;">physarum polycephalum (</em>lodo com muitas cabeças) e, continuando na ciência, pertence a um sub-conjunto de fungos conhecidos por fungos plasmodiais que são constituídos por uma única célula de grandes dimensões que possuí milhares de núcleos.</span></div>
<div style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">Muita da atenção que tem recaído sobre o Blob prende-se com o facto de esta espécie de logo constituído por uma só célula possuir quase 720 sexos. Explica <a href="https://www.wired.co.uk/article/slime-mould-the-blob-paris-zoo" style="background-attachment: scroll; background-clip: border-box; background-color: transparent; background-image: none; background-origin: padding-box; background-position-x: 0px; background-position-y: 0px; background-repeat: repeat; background-size: auto; box-sizing: border-box; color: #1e88e5; cursor: pointer; text-decoration: none;" target="_blank">a revista Wired,</a> que "no Physarum, o sexo é determinado por uma variedade de genes diferentes que vêm em múltiplas variantes. Os fungos reproduzem-se libertando esporos que se desenvolvem em células sexuais, e para que uma reprodução bem-sucedida ocorra, tudo o que precisa acontecer é que duas células sexuais que contenham diferentes variantes desses genes sexuais se encontrem".</span></div>
<div style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">A questão da memória é, todavia, mais interessante para os investigadores do Centro Nacional de Investigação Científica em França. É que os "blobs" parecem ter adquirido memória sem ter nenhum dos componentes biológicos normalmente necessários para que as memórias se formem. O que levanta inúmera questões, nomeadamente sobre a forma de aprendizagem e sobre a extensão do conceito de cognição a seres não-humanos.</span></div>
<div style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">Bruno David, diretor do Museu de História Natural de Paris, do qual faz parte o Parque Zoológico onde Blob se encontram, <a href="https://www.youtube.com/watch?v=-FH4PPHvaE0" style="background-attachment: scroll; background-clip: border-box; background-color: transparent; background-image: none; background-origin: padding-box; background-position-x: 0px; background-position-y: 0px; background-repeat: repeat; background-size: auto; box-sizing: border-box; color: #1e88e5; cursor: pointer; text-decoration: none;" target="_blank">referiu-se a este lodo com muitas cabeças</a> como "um dos mistérios da natureza". "Não sabemos o que é, se um animal, se um fungo. Não é uma planta, disso estamos certos, mas será algo intermédio entre um fungo e um animal? (...) É capaz de aprender. Se o colocarmos num labirinto consegue encontrar a melhor rota para o seu alimento. (...) Se juntarmos dois blobs, um ensinará o outro".</span></div>

<span style="font-family: Times, Times New Roman, serif;"><span style="background-color: white; color: #333333; font-size: 18px; text-align: start;">Não são boas notícias. A poluição por microplásticos já chegou à Antártida, revela um estudo da Universidade de Coimbra (UC) publicado hoje na </span><a href="https://www.nature.com/articles/s41598-019-50621-2" style="-webkit-font-smoothing: antialiased; background: 0px 0px rgb(255, 255, 255); box-sizing: border-box; color: #f27967; cursor: pointer; font-size: 18px; overflow-anchor: none; text-align: start; text-decoration-line: none;">revista Scientific Reports, do grupo Nature</a><span style="background-color: white; color: #333333; font-size: 18px; text-align: start;">.</span></span></div>

<div style="text-align: justify;">
<span style="background-color: white; color: #333333; font-size: 18px;"><span style="font-family: Times, Times New Roman, serif;">Uma equipa de investigadores do Centro de Ciências do Mar e do Ambiente (MARE) da Faculdade de Ciências e Tecnologia da Universidade de Coimbra (FCTUC) encontrou, pela primeira vez, microplásticos em pinguins da Antártida, confirmando que este tipo de poluição já entrou na cadeia alimentar marinha.</span></span></div>

<span style="font-family: Times, Times New Roman, serif;"><span style="background-color: white; color: #333333; font-size: 18px;">Ao analisarem a dieta de pinguins </span><em style="-webkit-font-smoothing: antialiased; background-color: white; box-sizing: border-box; color: #333333; font-size: 18px; overflow-anchor: none;">gentoo Pygocelis papua</em><span style="background-color: white; color: #333333; font-size: 18px;"> em duas regiões da Antártida, os investigadores observaram que 20% das 80 amostras de fezes das aves continham microplásticos (partículas de plástico menores que 5mm de comprimento) de diversas tipologias, formas e cores, o que indica uma grande variedade de possíveis fontes destes microplásticos.</span></span></div>
<div style="text-align: justify;">
<span style="background-color: white; color: #333333; font-size: 18px;"><span style="font-family: Times, Times New Roman, serif;"><br /></span></span></div>
<div style="text-align: justify;">
<span style="background-color: white; color: #333333; font-size: 18px;"><span style="font-family: Times, Times New Roman, serif;">A poluição marinha por plásticos é reconhecidamente uma ameaça aos oceanos em todo o mundo mas só recentemente tem havido um aumento do esforço científico sobre microplásticos. Em zonas mais remotas do planeta, como a Antártida, esperava-se que a presença de microplásticos fosse muito reduzida, embora estudos recentes já tenham encontrado microplásticos em sedimentos e nas águas do Oceano Antártico.</span></span></div>
<div style="text-align: justify;">
<span style="background-color: white; color: #333333; font-size: 18px;"><span style="font-family: Times, Times New Roman, serif;"><br /></span></span></div>
<div style="text-align: justify;">
<span style="background-color: white; color: #333333; font-size: 18px;"><span style="font-family: Times, Times New Roman, serif;">Para Filipa Bessa, autora principal do artigo, "é alarmante que microplásticos já tenham chegado à Antártida. O nosso estudo é o primeiro a registar microplásticos em pinguins e na cadeia alimentar marinha Antártica".</span></span></div>
<div style="text-align: justify;">
<span style="background-color: white; color: #333333; font-size: 18px;"><span style="font-family: Times, Times New Roman, serif;"><br /></span></span></div>
<div style="text-align: justify;">
<span style="background-color: white; color: #333333; font-size: 18px;"><span style="font-family: Times, Times New Roman, serif;">A investigadora nota que "a variedade de microplásticos encontrados nos pinguins poderá indicar diferentes fontes de poluição, indiciando uma difícil solução para este problema".</span></span></div>
<div style="text-align: justify;">
<span style="background-color: white; color: #333333; font-size: 18px;"><span style="font-family: Times, Times New Roman, serif;"><br /></span></span></div>
<div style="text-align: justify;">
<span style="background-color: white; color: #333333; font-size: 18px;"><span style="font-family: Times, Times New Roman, serif;">Por seu lado, José Xavier, autor sénior do artigo, afirma que "este estudo vem na altura certa, pois os microplásticos podem causar efeitos tóxicos nos animais marinhos e nada se sabe sobre o que eles poderão provocar nos animais da região Antártica".</span></span></div>
<div style="text-align: justify;">
<span style="background-color: white; color: #333333; font-size: 18px;"><span style="font-family: Times, Times New Roman, serif;"><br /></span></span></div>
<div style="text-align: justify;">
<span style="background-color: white; color: #333333; font-size: 18px;"><span style="font-family: Times, Times New Roman, serif;">Por isso, salienta o também docente do Departamento de Ciências da Vida da FCTUC, "esta descoberta é de muita importância para desenvolver novas medidas para reduzir a poluição na Antártida, particularmente relacionada com plásticos, podendo servir de exemplo para outras regiões do mundo".</span></span></div>

Esta é a estimativa que a Organização Mundial de Saúde (OMS) faz para uma realidade que, só em 2017, vitimou cerca de 1000 pessoas em Portugal, segundo dados da Direção-Geral de Saúde. As explicações são do Professor e médico psiquiatra Joaquim Cerejeira. O Dia Mundial da Prevenção do Suicídio assinala-se a 10 de setembro.</span></span></div>

O suicídio define-se como um ato em que um indivíduo põe termo à própria vida de forma intencional e voluntária. Embora possa afetar todo o tipo de pessoas, este comportamento é mais frequente em homens acima dos 65 anos e em jovens entre os 15 e os 24 anos. Outros conceitos relacionados são a tentativa de suicídio, na qual a pessoa tem intenção de morrer, mas sobrevive, e os comportamentos autolesivos, sem intenção letal, como por exemplo cortes infligidos no próprio corpo.</div>
<div style="text-align: justify;">
<br /></div>
<div style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
Na maioria dos casos, os comportamentos suicidários estão relacionados com fatores psicopatológicos, que vão desde a presença de uma depressão, esquizofrenia ou doença bipolar, estados de ansiedade, consumo de álcool ou de outras substâncias.</div>
<div style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
Outros fatores como tentativas de suicídio anteriores, o historial suicidário na família, o contacto com este tipo de comportamento nos média, assim como algumas caraterísticas de personalidade (agressividade, ansiedade, perfecionismo, etc.), podem ser fatores precipitantes de comportamentos letais.</div>
<div style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
Os contextos familiar, social, económico e cultural também desempenham um papel crucial no desenvolvimento de quadros de grande angústia que podem resultar em pensamentos suicidas, os quais são tidos pelo indivíduo como a solução que irá acabar com a dor que está a sentir. Divórcio, dificuldades financeiras, desemprego, violência, bullying, morte de um ente querido, entre muitos outros, são algumas realidades que podem afetar de forma negativa o estado psicológico da pessoa e, por sua vez, despoletar atos suicidários.</div>
<div style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
Contudo, a presença de um ou mais fatores de risco não implica, por si só, que a pessoa atente contra a sua própria vida. Isto porque os pontos anteriormente mencionados manifestam-se de forma distinta em cada indivíduo.</div>
<h4 style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 20px; font-style: normal; font-variant: normal; font-weight: 700; letter-spacing: normal; line-height: 26px; margin-bottom: 20.8px; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<strong style="box-sizing: border-box; font-weight: 700;">Sinais de alarme</strong></h4>
<div style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
São as pessoas mais próximas do indivíduo, como familiares e amigos, que têm um papel fulcral na identificação de sinais indicadores da presença de fatores de risco para comportamentos suicidários, dos quais se destacam: o sofrimento e tristeza profunda; o isolamento social; a baixa autoestima; as alterações repentinas de humor; a adoção de comportamentos de risco, como o consumo abusivo de bebidas alcoólicas ou substâncias psicotrópicas; os sentimentos de culpabilidade e de desvalorização pessoal; abordar temas relacionados com a morte ou o suicídio com maior frequência; ou expressar a intenção de cometer suicídio.</div>
<div class="content" style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 16px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; orphans: 2; position: relative; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<div style="box-sizing: border-box; font-size: 17.93px; margin-bottom: 23.31px; margin-top: 0px;">
Este último ponto jamais deve ser desvalorizado, dado que é frequente que a pessoa verbalize que pretende suicidar-se antes de realizar o ato.<strong style="box-sizing: border-box; font-weight: 700;"></strong></div>

Reconhecido o problema, a etapa seguinte passa por tentar ajudar a pessoa a sair da angústia em que se encontra, mostrando-lhe que existe um caminho diferente para solucionar aquilo que a atormenta. Para isso, existem várias medidas que deve tomar, nomeadamente:</div>
<ul style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-family: "Georgia",serif; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; line-height: 25.1px; margin-bottom: 17.93px; margin-left: 0px; margin-right: 0px; margin-top: 17.93px; orphans: 2; padding-bottom: 0px; padding-left: 26px; padding-right: 0px; padding-top: 0px; text-align: left; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<li style="box-sizing: border-box; margin-bottom: 8.96px; margin-left: 0px; margin-right: 0px; margin-top: 8.96px;"><div style="text-align: justify;">
Levar a sério o estado em que a pessoa se encontra e não minimizar o seu sofrimento;</div>
</li>
<li style="box-sizing: border-box; margin-bottom: 8.96px; margin-left: 0px; margin-right: 0px; margin-top: 8.96px;"><div style="text-align: justify;">
Ouvi-la com atenção, de forma a perceber o que se passa e como pode ajudar;</div>
</li>
<li style="box-sizing: border-box; margin-bottom: 8.96px; margin-left: 0px; margin-right: 0px; margin-top: 8.96px;"><div style="text-align: justify;">
Não criticar as suas intenções e tentar compreender as razões do seu desespero;</div>
</li>
<li style="box-sizing: border-box; margin-bottom: 8.96px; margin-left: 0px; margin-right: 0px; margin-top: 8.96px;"><div style="text-align: justify;">
Tentar perceber quais os planos e métodos que a pessoa tem para concretizar o suicídio;</div>
</li>
<li style="box-sizing: border-box; margin-bottom: 8.96px; margin-left: 0px; margin-right: 0px; margin-top: 8.96px;"><div style="text-align: justify;">
Transmitir empatia e confiança, demonstrando que através de si há sempre a possibilidade de desabafar e de encontrar conforto e ajuda para os problemas;</div>
</li>
</ul>
<div style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
O tratamento a adotar irá depender dos fatores que desencadearam as intenções suicidas. Caso estejamos perante um quadro psicopatológico, a psicoterapia e a utilização de fármacos são dois métodos a considerar, assim como, em última instância, o internamento.</div>
<div style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
Para os restantes casos, o tratamento e acompanhamento psicológico regular poderão ajudar a pessoa a ultrapassar o estado de angústia extrema em que se encontra.</div>

<span style="font-family: Times, "Times New Roman", serif;">Por ser uma região vasta, mas homogénea, este geoparque “oferece uma grande variedade de produtos turísticos, tendo como mais-valia comum a natureza e as excelentes infraestruturas”, pode ler-se no seu sítio da Internet.</span></div>

<span style="font-family: Times, "Times New Roman", serif;">“Todo este manto verde guarda, cioso, 41 sítios de interesse geológico (geossítios) e quase metade dele está classificado pela Rede Natura 2000″, refere o seu sítio da Internet, chamando a atenção para os percursos pedestres, os trilhos de BTT, os desportos de aventura do Paiva, as aldeias tradicionais, o artesanato, o folclore e as tradições que continuam a contar a história daquele território.</span></div>

<span style="font-family: Times, "Times New Roman", serif;">Também o arquipélago dos Açores apresenta “uma rica e vasta geodiversidade e um importante património geológico, composto por diversos locais de interesse científico, pedagógico e turístico”, segundo o seu sítio na Internet.</span></div>

<span style="font-family: Times, "Times New Roman", serif;">“O Geoparque Açores (com 12.884 quilómetros quadrados) assenta numa rede de geossítios dispersos pelas nove ilhas e zona marinha envolvente”, explica, apontando “vulcões, caldeiras, lagoas, campos lávicos, fumarolas, águas termais, grutas e algares vulcânicos, fajãs, escarpas de falha e depósitos fossilíferos marinhos” como elementos caracterizadores do património geológico.</span></div>

<span style="font-family: Times, "Times New Roman", serif;">O Geoparque Terras de Cavaleiros, que coincide com os limites administrativos do concelho de Macedo de Cavaleiros, tem 700 quilómetros quadrados e integra “um importante património geológico ao qual se soma um grande património de biodiversidade, um notável património histórico-cultural, os produtos locais, a rica gastronomia e a arte de bem receber das suas gentes”.</span></div>

<span style="font-family: Times, "Times New Roman", serif;">De acordo com o seu sítio na Internet, o geoparque “assume um papel proativo no sentido de estimular o <scroll-bookmark class="sb-count" data-word-count="400" style="box-sizing: border-box;">turista</scroll-bookmark> a viver experiências gratificantes, que o façam tornar-se num protagonista ativo e não um mero observador da paisagem”.</span></div>

Outra questão pedia que as pessoas classificassem de zero a dez a dor que estavam a sentir.

<div style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">Aos dados resultam de um estudo coordenado pela organização não-governamental (ONG) cabo-verdiana BIOS.CV, com sede na ilha da Boa Vista, e que com o apoio de outras organizações do género, em mais sete ilhas (apenas a Brava e Santo Antão não foram estudadas), monitorizaram as temperaturas, projetando depois as consequências para a espécie de tartaruga caretta caretta, predominante no país.</span></div>
<div style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">As conclusões, agora conhecidas, têm como base dados recolhidos entre 2011 e 2013 (maio a novembro, época de nidificação) em 40 praias de Cabo Verde, em que a temperatura — que define o sexo das tartarugas – foi monitorizada a cada 30 minutos.</span></div>
<div class="content" style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 16px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; orphans: 2; position: relative; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<div style="box-sizing: border-box; font-size: 17.93px; margin-bottom: 23.31px; margin-top: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">“Estamos a falar de um claro aumento das temperaturas, que por sua vez definem o sexo dos répteis. Produzindo cada vez mais fêmeas, isso compromete o desenvolvimento da espécie”, explicou à agência Lusa Samir Martins, investigador e presidente da BIOS.CV.</span></div>
<div style="box-sizing: border-box; font-size: 17.93px; margin-bottom: 23.31px; margin-top: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">O fenómeno, acrescentou, é cada vez mais evidente nas praias de areia negra de Cabo Verde, cuja nidificação já dá origem a 99% de fêmeas, mas o problema também já é visível nas praias de areia branca. Nestas, as fêmeas também já são a maioria, com um peso de 60 a 70%.</span></div>

<span style="font-family: Times, "Times New Roman", serif;">“Nas praias de areia negra o fenómeno é mais grave porque o calor é mais absorvido e com isso a temperatura aumenta”, acrescentou Samir Martins.</span></div>
<div class="content" style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; position: relative; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">Ainda assim, garante que o problema é generalizado: “O que vemos é que, independentemente da cor da areia e da ilha, vão nascer [no futuro] mais de 90% de fêmeas”, alertou, apoiando-se nas extrapolações da Universidade de Exeter, do Reino Unido, que trabalhou os dados recolhidos no terreno.</span></div>
<div class="content" style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; position: relative; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">As projeções, publicadas num artigo científico, apontam que a subida das temperaturas, mesmo num cenário favorável de emissões de gases de efeito estufa, levará a que 99,86% das tartarugas caretta caretta que vão nascer em 2100, em Cabo Verde, serão fêmeas.</span></div>
<div class="content" style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; position: relative; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">“Está mesmo em causa a continuidade das tartarugas em Cabo Verde”, sublinhou Samir Martins, acrescentando que um outro estudo em curso já aponta também que as crias estão a nascer “mais fracas”.</span></div>
<div class="content" style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; position: relative; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">“O que as torna mais vulneráveis à predação nas praias”, explicou.</span></div>
<div class="content" style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; position: relative; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">A criação <scroll-bookmark class="sb-count" data-word-count="400" style="box-sizing: border-box;">de</scroll-bookmark> zonas de sombra nas áreas dos ninhos de tartaruga é uma das recomendações dos especialistas, para tentar inverter o cenário.</span></div>

<span style="font-family: Times, "Times New Roman", serif;">“Ao baixar a temperatura nos ninhos, estamos a permitir uma reprodução mais equilibrada, em termos de sexo das tartarugas”, sublinhou o investigador.</span></div>
<div class="content" style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; position: relative; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">Outra solução passa pela colocação de água — exclusivamente doce — sobre os ninhos, algo que face à seca que Cabo Verde atravessa há vários anos acaba por ser inviável.</span></div>
<div class="content" style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; position: relative; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">“Mas criar sombras é viável, basta uns ramos e conseguimos minimizar o problema”, garantiu, apelando ao apoio do Ministério do Ambiente.</span></div>

<span style="font-family: Times, "Times New Roman", serif;">Em Cabo Verde há registo de uma média de 18.790 ninhos de tartarugas nos últimos 10 anos.</span></div>

Abstract</h3>
<div style="text-align: justify;">
Hydrogel-based biomimetic scaffolds have generated broad interest due to their tunable physical, chemical, and biological properties for bone tissue engineering applications. We fabricated eggshell microparticle (ESP) reinforced gelatin-based hydrogels to obtain mechanically stable and biologically active three-dimensional (3D) constructs that can differentiate pre-mature cells into osteoblasts. Physical properties including swelling ratio, degradation, and mechanical properties of the composite hydrogels were investigated. Pre-osteoblasts were encapsulated within the ESP-reinforced hydrogels to study their differentiation and evaluate mineral deposition by these cells. The ESP-reinforced gels were then subcutaneously implanted in a rat model to determine their biocompatibility and degradation behaviors. The composite hydrogels have shown outstanding tunability in physical and biological properties holding substantial promise for engineering mineralized tissues (<em style="line-height: 28px;">e.g.</em> bone, cartilage, tooth, and tendon). These 3D scaffolds enabled the differentiation of pre-osteoblasts without the use of specialized osteogenic growth medium. The ESP-reinforced gels exhibited significant enhancement in mineralization by pre-osteoblasts. These behaviors are positively correlated with increasing concentrations of ESP. Findings suggest that our novel composite hydrogel exhibits superior mechanical properties and indicates a favorable <em style="line-height: 28px;">in vivo</em> response by subcutaneous implantation in a rat model.</div>

<div style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 20px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin: 0px 0px 19px; orphans: 2; padding: 0px; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">Tradicionalmente, a ação do ibuprofeno foi explicada através do seu efeito inibitório sobre uma atividade enzimática do organismo, que está na origem da produção de moléculas pro-inflamatórias conhecidas como prostaglandinas.</span></div>
<div style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 20px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin: 0px 0px 19px; orphans: 2; padding: 0px; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">O trabalho da equipa liderada pelo investigador do Departamento de Genética Humana do INSA, Peter Jordan, revelou que o ibuprofeno tem ainda outro modo de ação anticancerígena: “impede as células cancerígenas de produzirem variantes tumorigénicas de certas proteínas, num processo conhecido como 'splicing' alternativo”.</span></div>

<span style="font-family: Times, "Times New Roman", serif;">Em declarações à agência Lusa, Peter Jordan explicou que já se conhecia que a toma regular deste medicamento podia em casos de risco prevenir o aparecimento do cancro do colón, “mas achava-se sempre que tinha a ver com o efeito do ibuprofeno e as outras drogas, a aspirina também é um exemplo ao nível da formação de prostaglandinas”.</span></div>

<span style="font-family: Times, "Times New Roman", serif;">No caso do cancro do cólon, uma das variantes tumorigénicas que a equipa de investigação identificou anteriormente caracteriza cerca de 10% dos tumores e estimula a taxa de sobrevivência das células malignas.</span></div>

<span style="font-family: Times, "Times New Roman", serif;">Segundo o investigador, “o ibuprofeno, mas não outros AINE como a aspirina, ao contrariar a produção desta variante consegue inibir o crescimento das células malignas", explicou o investigador.</span></div>

<span style="font-family: Times, "Times New Roman", serif;">Peter Jordan explicou que “existem subgrupos geneticamente distintos de cancro do colón e que o ibuprofeno atua sobretudo sobre um subgrupo que explica 10 a 15%” destes tumores.</span></div>

<span style="font-family: Times, "Times New Roman", serif;">Para o geneticista, são importantes estudos que identificam marcadores de progressão maligna no início do desenvolvimento tumoral para desenvolver um diagnóstico mais preciso e uma terapia mais eficaz que seja dirigida especificamente às alterações génicas presentes em cada tumor do doente.</span></div>

<span style="font-family: Times, "Times New Roman", serif;">O investigador adiantou que a publicação na European Medical Journal, uma revista dirigida aos médicos, desta investigação realizada ao longo dos últimos anos poderá chamar a atenção de que valeria “a pena investir mais na utilização do ibuprofeno em certos casos de doentes”.</span></div>

<span style="font-family: Times, "Times New Roman", serif;">Segundo os dados mais recentes sobre a incidência de cancro divulgados pela Agência Internacional de Investigação do Cancro (IARC), o cancro do cólon passou a ser, em 2018, a primeira causa de novos casos de cancro em Portugal.</span></div>

O grande impacte. A Terra primitiva partilhava a sua órbita com o protoplaneta Tea, que foi aumentando de tamanho. Com a agregação de materiais devido à gravidade, a sua posição tornou-se cada vez mais instável até colidir com a Terra. 2. Anel de escombros. A matéria ejectada por esta colisão, formada sobretudo por materiais mais leves, produziu um anel de escombros que orbitava o novo planeta. Os materiais mais pesados, como o ferro, ficaram presos na Terra recém-formada. 3. Condensação. Com o tempo e devido à acção da gravidade, o anel circumplanetário de escombros começou a desfazer-se em alguns corpos que, por fim, se condensaram numa única grande massa que deu lugar à Lua.</span></div>

<span style="font-family: Times, "Times New Roman", serif;">A hipótese mais consensual sobre a formação da Lua foi a do “impacte gigante”, segundo a qual o nosso satélite terá resultado dos restos de uma colisão do protoplaneta Terra com um hipotético planeta, baptizado com o nome de Tea, há 4.500 milhões de anos, durante as fases iniciais da formação do Sistema Solar. A Terra actual resulta assim da mistura de dois corpos e a Lua teria surgido dos materiais projectados pelo embate. <br style="background-attachment: scroll; background-clip: border-box; background-color: transparent; background-image: none; background-origin: padding-box; background-position-x: 0%; background-position-y: 0%; background-repeat: repeat; background-size: auto; color: #444444; text-shadow: none;" /> Um incidente desta natureza coincide com os modelos informáticos de formação de sistemas planetários, que prevêem colisões planetárias catastróficas e frequentes em momentos iniciais da formação de um planeta.</span></div>

<span style="font-family: Times, "Times New Roman", serif;">As rochas lunares e terrestres apresentam proporções idênticas de isótopos químicos, o que revela uma origem comum. Apesar disso, a Lua tem menor densidade do que a Terra e possui uma quantidade muito reduzida de ferro no seu núcleo. Caso se tivessem formado juntas, uma em redor da outra, ambas teriam proporções semelhantes de ferro. De acordo com outra corrente, o núcleo de ferro de Tea fundiu-se com o do protoplaneta Terra, retendo a maior parte dos elementos densos e deixando uma quantidade residual na Lua.</span></div>

<span style="font-family: Times, "Times New Roman", serif;">A descoberta é hoje relatada na revista científica “Journal of Vertebrate Paleontology”, na qual se diz que até agora se pensava que aves tão grandes só tinham existido nas ilhas de Madagáscar e da Nova Zelândia.</span></div>
<div style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">A espécie agora descoberta numa caverna de Táurida, na costa do Mar Negro, remete para uma ave tão grande como o pássaro-elefante de Madagáscar ou o moa da Nova Zelândia.</span></div>
<div style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">“Quando senti pela primeira vez o peso da ave cujo osso da coxa eu segurava na mão pensei que devia ser um fóssil de um pássaro-elefante malgaxe, porque nenhuma ave desse tamanho tinha sido alguma vez encontrada na Europa. No entanto, a estrutura do osso contou uma história diferente”, disse o autor principal da descoberta agora relatada, Nikita Zelenkov, da Academia Russa de Ciências.</span></div>
<div style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">Ressalvando que ainda não há dados suficientes para dizer se a ave se relaciona com as avestruzes ou não, o investigador estimou que pesaria cerca de 450 quilos, quase o dobro da maior moa, três vezes maior que a maior ave viva, a avestruz, e quase tão grande como um urso polar adulto.</span></div>
<div style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">Esta é a primeira vez que uma ave assim tão grande, atribuída à espécie “Pachystruthio dmanisensis”, é relatada em qualquer lugar do hemisfério norte. Teria pelo menos 3,5 metros de altura e não voava.</span></div>
<div style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">Os investigadores notam ainda que devia ser uma melhor corredora do que o pássaro-elefante, devido ao fémur relativamente longo e fino.</span></div>
<div style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">Outros fósseis encontrados ao lado da ave ajudam a avançar que tenha vivido num período entre 1,5 a dois milhões de anos atrás.</span></div>
<div style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">A rede de cavernas de Táurida só foi descoberta no verão passado, quando estava a ser construída uma nova autoestrada. No ano passado foram desenterrados restos de mamutes e pode haver muitas mais informações no local sobre o passado distante da Europa, disse Zelenkov.</span></div>

Um feito com milhares de anos e sem testemunho para a posteridade. Mais tarde, no Próximo Oriente, o Homem tomou as rédeas aos antepassados dos nossos iogurtes. E não mais os largou, convertendo-os numa narrativa saborosa. </span></span></div>

Não o sabiam os nossos antepassados do Neolítico, mas estavam, com este novo passo civilizacional, a inventar uma parte do futuro comum da humanidade. O Homem aprendeu a domesticar. Levou milhares de anos a aperfeiçoar as técnicas e a “moldar” os antepassados dos atuais carneiros, búfalos, ovelhas, cabras, vacas, entre dezenas de outras espécies, às necessidades das comunidades.</span></span><b></b><i></i><u></u><sub></sub><sup></sup><strike></strike></div>

<span style="font-family: "times" , "times new roman" , serif;">Com a domesticação e pastorícia, os mamíferos humanos apegavam-se a um alimento que não mais deixariam, o leite de espécies bovinas, ovinas e caprinas.

<span style="font-family: "times" , "times new roman" , serif;">Dos antecessores do iogurte, posteriores ao período Pré-histórico, sabe-se como certo que o processo de fermentação ligado a este produto já era conhecido dois mil anos a.C. por povos do Médio Oriente. Faziam-no como forma de preservar o leite. Porém, o iogurte como produto próximo ao que hoje conhecemos, terá sido criado por tribos nómadas da Europa Oriental e Próximo Oriente, constituindo parte da dieta no Médio Oriente e bacia mediterrânica durante séculos.</span></div>

<span style="font-family: "times" , "times new roman" , serif;">Nos desertos da Turquia os pastores armazenavam o leite fresco em recipientes feitos de pele de cabra. Os sacos eram, então, atados ao carregamento levado pelos camelos. O calor dos animais e a própria temperatura ambiente, elevada, propiciava a multiplicação de bactérias ácidas. Horas depois o leite havia-se convertido numa massa semissólida e coagulada.

Tem o termo o seu fundo de verdade uma vez que ao iogurte, alimento bem tolerado pelo organismo, dado o baixo teor de lactose, se têm reconhecido propriedades preventivas de doenças, nomeadamente do foro digestivo. As proteínas do leite, com alto valor biológico, são parcialmente pré-digeridas devido às bactérias lácticas, permitindo a sua melhor digestão. Uma hora após ter sido ingerido, cerca de 90% do iogurte foi digerido, enquanto o leite fica na fasquia dos 30%. O iogurte é rico em vitaminas e com um largo espectro de minerais.</span></span></div>

Os aldeões encheram o seu bornal de leite, confiando que este se estragaria sob o calor tórrido do deserto. Ao invés, as temperaturas mantiveram-se moderadas e a agitação constante tornou o leite numa substância branca, bastante apetitosa. Fortificado com a dieta à base de iogurte, o mensageiro pode prosseguir o seu caminho.</span></div>

O facto surpreendia o investigador uma vez que a Bulgária, território árido, na época continuamente sob invasões estrangeiras, estar longe de ser uma região desenvolvida. Estudando a alimentação da população, Metchnikoff constatou que esta assentava basicamente em produtos hortícolas e no iogurte. Não lhe parecendo que a longevidade se devesse aos hortícolas e defendendo o princípio de que dietas contendo lactobacilos, podem proteger o corpo da invasão de patogénicos, o investigador concluiu que o iogurte poderia melhorar e prolongar a qualidade de vida. Este russo acreditava que o consumo regular de iogurte podia levar o ser humano a viver até uns incríveis 150 anos.</span></span></span></div>

Este processo que impede a deterioração do leite promovendo a sua conservação é conhecido como pasteurização. Pesquisadores do Instituto Pasteur descobriram diferentes efeitos benéficos para a saúde de acordo com cada espécie de microrganismos que produzia a fermentação.</span></div>

<span style="font-family: Times, "Times New Roman", serif;">No contexto do artigo recentemente publicado com o título <a href="https://24.sapo.pt/opiniao/artigos/tem-a-certeza-que-foi-voce-que-pediu-uma-agua-engarrafada" style="background-attachment: scroll; background-clip: border-box; background-color: transparent; background-image: none; background-origin: padding-box; background-position-x: 0px; background-position-y: 0px; background-repeat: repeat; background-size: auto; box-sizing: border-box; color: #1e88e5; cursor: pointer; text-decoration: none;" target="_blank">"Tem a certeza que foi você que pediu uma água engarrafada?”</a> justifica-se esclarecer sobre especificidades, qualidade e características diferenciadoras das águas minerais naturais e de nascente portuguesas.</span></div>

<span style="font-family: Times, "Times New Roman", serif;">As águas minerais naturais são recursos do domínio público do Estado. A par das águas de nascente, são recursos naturais de excepcional qualidade, atestada pelos laboratórios do Instituto Nacional Doutor Ricardo Jorge (INSA), do Instituto Superior Técnico (IST) e do Instituto Nacional de Engenharia e Tecnologia Industrial (INETI), entre outros. Por vezes, há confusão ou insuficiente esclarecimento (mea culpa!) sobre quais as especificidades das águas minerais naturais e de nascente. É importante distinguir.</span></div>
<div style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">- As águas minerais naturais e de nascente têm sempre origem subterrânea, o que lhes garante protecção acrescida face a agressões externas. Os aquíferos são geridos, de forma sustentada, em quantidade (renovação dos caudais) e qualidade (perímetros de proteção), por profissionais de geologia altamente qualificados. As águas de torneira são, de forma predominante, captadas nos rios ou nas albufeiras das barragens.</span></div>
<div style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">- As águas minerais naturais e as águas de nascente são as únicas 100% naturais, não têm quaisquer tratamentos químicos. São caracterizadas pela sua pureza original! As águas de torneira têm de ser sujeitas a processos de tratamento químico , através da adição de cloro, que lhes permite ter a potabilidade que não têm na origem.</span></div>

<span style="font-family: Times, "Times New Roman", serif;">- O engarrafamento de águas minerais naturais e de nascente faz-se na proximidade dos aquíferos, com a preservação das características originais da água. As unidades de engarrafamento estão fixadas às regiões do interior onde estão os aquíferos e não podem ser deslocalizadas! O transporte de água de torneira faz-se por rede, normalmente percorrendo grandes distâncias, dependendo a qualidade de diferentes factores (material das tubagens, rupturas, etc).</span></div>

<span style="font-family: Times, "Times New Roman", serif;">- As águas minerais naturais e de nascente são protegidas e estão identificadas pela sua origem. O rótulo garante ao consumidor informação sobre o que está a beber! As águas de torneira podem ter diferentes origens e não fornecem ao consumidor, no ponto de consumo, qualquer tipo de informação.</span></div>
<div class="content" style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; position: relative; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">- A grande diversidade geológica de Portugal traduz-se numa enorme <scroll-bookmark class="sb-count" data-word-count="400" style="box-sizing: border-box;">variedade</scroll-bookmark> de águas minerais naturais e de nascente o que permite ao consumidor fazer as escolhas da sua preferência, de gosto e paladar. As águas de torneira não oferecem ao consumidor qualquer escolha.</span></div>
<div class="content" style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; position: relative; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">- As águas minerais naturais e de nascente são protegidas por embalagens seguras e 100% recicláveis, cumprindo exigentes requisitos de segurança alimentar e de rastreabilidade que não são exigidos às águas de torneira .
É também importante distinguir entre os diferentes tipos de águas engarrafada. Há muita confusão!
Em Portugal, 99% da água engarrafada vendida é de água mineral natural e de água de nascente, de origem portuguesa.</span></div>
<div class="content" style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; position: relative; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">Ao contrário, noutros países, como Estados Unidos, Canadá, Austrália, as águas engarrafadas mais vendidas são águas preparadas e tratadas, que não possuem origem subterrânea identificada e protegida, nem apresentam pureza original. Faz toda a diferença quando são divulgadas conclusões de estudos sobre questões de qualidade associadas às águas engarrafadas nesses países e que não podem, de modo algum, ser estendidas à realidade nacional, como por vezes sucede por ignorância, má fé ou oportunismo.</span></div>
<div class="content" style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; position: relative; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">As águas minerais naturais e de nascente são património de todos os portugueses. Temos de nos orgulhar das excelentes águas minerais naturais e de nascente que a natureza do país nos oferece, das marcas que temos que também são o espelho de Portugal e do país que somos.</span></div>

É, no fundo, uma extensão do sistema imunitário que precisa de ser cuidada para evitar infeções e doenças dermatológicas.</span></span></div>

<span style="font-family: Times, "Times New Roman", serif;">Esta camada exterior permite à pele manter um pH normal, produzindo nutrientes, enzimas e lípidos essenciais para o seu bom funcionamento e atuando como regulador ativo do sistema imunitário.</span></div>

<span style="font-family: Times, "Times New Roman", serif;">Há vários fatores que podem perturbar o microbioma da pele, alterando temporariamente a sua diversidade e equilíbrio: toma de antibióticos e antifúngicos, hábitos de higiene excessivos ou agressivos, estados de saúde, estilos de vida, hábitos alimentares, clima, stress e mudanças no microambiente da pele.</span></div>

<span style="font-family: Times, "Times New Roman", serif;">A destruição do microbioma compromete a integridade da pele e aumenta o risco de infeções por microrganismos patogénicos e doenças de pele como dermatite atópica, acne, rosácea e psoríase.</span></div>

<span style="font-family: Times, "Times New Roman", serif;">Por norma, a junk food são alimentos de rápida ou nenhuma confeção, refinados, enlatados e a baixo preço, o que favorece o aumento do seu consumo por parte da população mais jovem ou com menos recursos. Alguns dos exemplos mais comuns são os hambúrgueres, sandes, pizzas, batatas fritas, gelados, bolos, entre outros.</span></div>

<span style="font-family: Times, "Times New Roman", serif;">O seu consumo excessivo tem sido associado a doenças como a obesidade, diabetes tipo 2, hipertensão, patologias cardiovasculares e até mesmo desnutrição.</span></div>

<span style="font-family: Times, "Times New Roman", serif;">Seguir uma alimentação rica em açúcar e em gorduras, nomeadamente, saturadas pode fazer com que o organismo comece a tratar os alimentos ingeridos da mesma forma que reage a uma infecção bacteriana. Foi resultado de um estudo realizado na Universidade de Bona, na Alemanha.</span></div>
<div style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">Os testes foram feitos em ratinhos de laboratório - um dos animais modelo na comparação com os seres humanos - durante um mês. Estes roedores foram sujeitos a uma alimentação pobre em nutrientes e fibras e rica em gorduras e açúcares. No final do estudo, os animais desenvolveram uma elevada resposta inflamatória, semelhante a uma infeção bacteriana. Ou seja, este tipo de alimentação conduziu ao aumento do número de células imunes no sangue dos ratos. Mesmo após 4 semanas, muitos dos genes afetados continuaram a comportar-se de maneira alterada.</span></div>

<span style="font-family: Times, "Times New Roman", serif;">Do ponto de vista da alimentação saudável, o ser humano necessita aproximadamente de 50 a 60% de hidratos de carbono, 25 a 30% de gordura e 12 a 15% de proteína.</span></div>
<h4 style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 20px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; line-height: 26px; margin-bottom: 20.8px; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<strong style="box-sizing: border-box; font-weight: 700;"><span style="font-family: Times, "Times New Roman", serif;">Pessoas com excesso de peso mas desnutridas</span></strong></h4>
<div style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">Hoje em dia, os valores acima referidos não são seguidos, havendo um exagerado consumo de gorduras, proteínas animais, açúcares e sal através deste tipo de alimentação, fazendo com que haja uma carência de micronutrientes (vitaminas e minerais).</span></div>
<div style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">Embora sem sintomas visíveis, este tipo de desnutrição pode comprometer várias etapas do processo metabólico, principalmente o sistema imunitário e o desenvolvimento físico e mental.</span></div>
<div style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">Em alguns casos, por exemplo, o consumo destes alimentos pode causar excesso de peso e desnutrição em simultâneo.</span></div>
<div style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">Um indivíduo que consuma <scroll-bookmark class="sb-count" data-word-count="400" style="box-sizing: border-box;">frequentemente</scroll-bookmark> <em style="box-sizing: border-box;">junk food</em> e apresente obesidade poderá estar muito provavelmente desnutrido em simultâneo, devido à falta de nutrientes presentes nestes alimentos.</span></div>
<div style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">A curto prazo estas deficiências nutricionais levam a carências em determinados nutrientes, como é o caso do ferro, originando anemia. Ou ainda a problemas como o cansaço, baixo rendimento escolar, irritabilidade, dificuldades na cicatrização, dores de cabeça, calvície, ansiedade e acne.</span></div>
<div style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">A base de uma alimentação saudável necessita de se tornar muito mais valorizada na educação atual. Só desta forma é possível consciencializar as crianças e adultos para que possam saber escolher os alimentos certos, contrariando a indústria alimentar.</span></div>
<div style="-webkit-text-stroke-width: 0px; background-color: transparent; box-sizing: border-box; color: #333333; font-size: 17.93px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; margin-bottom: 23.31px; margin-top: 0px; orphans: 2; text-align: justify; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">
<span style="font-family: Times, "Times New Roman", serif;">É importante ressalvar que não será necessário deixar de comer por completo este tipo de alimentos, mas sim manter uma alimentação variada e equilibrada com o objetivo de obter todo o tipo de nutrientes.</span></div>
