Introduction: Fish is an important part of the Portuguese diet and a major source of long-chain omega-3 fatty acids. However, it also represents the main dietary source of methylmercury (MeHg), a neurotoxic compound especially harmful during critical stages of development such as pregnancy and early childhood. In response to European Commission Recommendation EU 2022/1342, Portugal undertook a national initiati...
Fresh sea urchin (Paracentrotus lividus) gonads are a delicacy with short seasonal availability, very often heterogeneous in size and intrinsic characteristics. This study aimed to valorise this resource through the preparation of canned products (with/without Porphyra spp.) and evaluate their physicochemical and sensory quality (3–12 months). Canning contributed to a decrease in protein, K and most carotenoids...
Considerando que o consumo de pescado é uma fonte importante de exposição ao metilmercúrio, a Comissão Europeia recomendou aos Estados- -membros que estabelecessem recomendações para o seu consumo. Assim, tendo sido criado um grupo de trabalho, é objetivo deste artigo apresentar o trabalho desenvolvido para a elaboração das recomendações de consumo de pescado adaptadas à população portuguesa, tendo em conta o p...
Um grupo de trabalho promovido pela Direção Geral da Alimentação e Veterinária (DGAV) e que integrou a Autoridade de Segurança Alimentar e Económica (ASAE), a Faculdade de Ciências da Nutrição e Alimentação da Universidade do Porto (FCNAUP), o Instituto Nacional de Saúde Doutor Ricardo Jorge (INSA), o Instituto Português do Mar e da Atmosfera (IPMA) e o Instituto de Saúde Pública da Universidade do Porto (ISPUP...
Bone metabolic disorders such as osteoporosis are characterized by the loss of mineral from the bone tissue leading to its structural weakening and increased susceptibility to fractures. A growing body of evidence suggests that inflammation and oxidative stress play an important role in the pathophysiological processes involved in the rise of these conditions. As the currently available therapeutic strategies a...
Portugal has high fish/seafood consumption, which may have both risks and benefits. This study aims to quantify the net health impact of hypothetical scenarios of fish/seafood consumption in the Portuguese population using a risk-benefit assessment methodology. Consumption data from the National Food, Nutrition and Physical Activity Survey 2015-2016 (n 5811) were used to estimate the mean exposure to methylmerc...
The seasonal variation in chemical and lipid composition of chub mackerel (Scomber colias) was evaluated monthly over one year (proximate chemical composition and lipid profile: fatty acid (FA) and lipid classes distribution). Significant seasonal changes regarding fat content were noticed (1.3–10.3 g/100 g), with the lowest fat content obtained in February (during spawning period), and the highest in September...
The project POLYPHOSPHATES aimed at: (i) the quantification of phosphates added to seafood products in general and particularly to salted and dried cod and (ii) the study of the effect of industrial and domestic processing on polyphosphates content in the final products. This project enabled to: (i) acquire and install a system of analysis by ionic liquid chromatography with condutimetric detection; (ii) assemb...
The composition of raw and cooked gilthead seabream (Sparus aurata) was analysed. The bioaccessibility of arsenic (As), selenium (Se), mercury (Hg), and methylmercury (MeHg) in raw and cooked fish was studied by an in vitro model. A risk-benefit assessment was performed taking into account bioaccessibility. The content of contaminants Hg and As displayed a significant increase for every culinary treatment, only...
O projeto CRASSOSADO nasceu do desafio lançado pelo ICNF - RNES às instituições científicas portuguesas com trabalhos de investigação recentes sobre as populações portuguesas de ostra, nomeadamente o MARE/FCUL, a Universidade de Aveiro/CESAM e o IPMA, tendo sido solicitado que se identificassem e estudassem os aspetos mais prementes para assegurar a conservação e a exploração sustentada deste recurso no estuári...
