O presente trabalho teve como objetivo realizar uma análise do estado da arte sobre os
benefícios do consumo regular de pescado na saúde humana. São apresentados e discutidos
alguns pontos-chave relacionados com o consumo de pescado, como por exemplo qual o papel
dos ácidos gordos da série ómega-3 na saúde humana. Esta dissertação teve como base uma
revisão bibliográfica dos trabalhos científicos existentes na literatura atual, e que focam a
influência do pescado na saúde humana. Como motores de pesquisa foram usadas as
plataformas PubMed e ScienceDirect. Os artigos foram selecionados através do uso de
distintas palavras-chave: Saúde, Pescado e Benefícios. Com este trabalho foi possível
caracterizar com detalhe a componente nutricional passível de ser fornecida através do
consumo de pescado. Particular ênfase é dada ao facto do pescado fornecer uma dieta rica e
equilibrada em proteínas, lípidos, vitaminas e minerais. O impacto do consumo de pescado na
saúde assume as mais diversas formas. Em particular o ómega-3, existente no pescado, são
essenciais para o adequado crescimento e desenvolvimento dos seres humanos, em particular
para mitigar os efeitos de doenças crónicas. É apresentada, com base em diferentes fontes, a
dosagem ideal de ómega-3, tendo em linha de conta os diferentes tipos de pescado. A
especificidade do consumo de pescado para mitigar o efeito de patologias crónicas é discutido
e particularizado para aquelas com maior prevalência, como por exemplo a doença
cardiovascular. Não menos importante é o impacto que os ómega-3 têm sobre o período de
gestação e nos primeiros anos de vida, sendo por isso dedicada uma secção deste trabalho à
discussão do tema, na qual é identificada uma clara influência deste constituinte nos períodos
em causa. Por último é enfatizada a influência do consumo de pescado no saudável
envelhecimento da população. Em suma parece existir um claro benefício do consumo
programado de pescado na saúde do ser humano. Fundamentada em diferentes fontes e
estudos, é identificável uma clara vantagem no consumo das doses recomendadas de pescado
desde o período da gestação, passando pelos primeiros anos de vida, até ao estágio de
envelhecimento do ser humano. Estes benefícios, em particular associados à existência de
ómega-3 e outros constituintes como por exemplo o selénio, são facilmente traduzíveis no
mitigar dos efeitos de diferentes patologias crónicas que podem afetar o ser humano, e até na
melhoria das capacidades cognitivas nos primeiros tempos de vida.
The main purpose of this work was to perform an analysis of the benefits of the regular fish consumption on human health. Some key aspects related to the seafood consumption, such as omega-3's role in human health are presented and further discussed. It was based on a literature review of scientific papers focusing on the influence of fish consumption on human health. PubMed and ScienceDirect platforms were the main research engine sources used. The scientific papers were selected through the use of different keywords, such as: health, seafood and benefits. It was possible to characterize the nutritional component that can be provided through fish consumption, and particular emphasis is given to the fish's ability to provide a balanced diet on proteins, lipids, vitamins and minerals. The impact of fish consumption on health assumes the most diverse forms. In particular omega-3, existing in fish, is essential for proper growth and development of humans. Based on different sources, the optimal dosage of omega-3, considering the different types of seafood, was defined. The specificity of the fish consumption to mitigate the effect of chronic pathologies, such as the cardiovascular disease, is also discussed. The impact that the omega-3 has over the period of pregnancy and the first years of life is of high relevance, and a section is therefore dedicated to the discussion of this topic. Finally, it is emphasized the influence of fish consumption in a healthy ageing. In summary a clear benefit in a balanced fish consumption for the health improvement of human beings was found. Based on different sources and studies, a clear advantage in the consumption of recommended doses of seafood since pregnancy, through the first years of life to the aging stage of the human being was identifiable. These benefits, particularly related to the existence of omega-3 and other constituents, such as selenium, are important to mitigate the effects of various chronic diseases that may unsettle humans, and even in improving the cognitive skills during the first years of life.
