Recomendações para o consumo de pescado para a população portuguesa

Apresentação pública das recomendações, INSA, 16 maio 2023; 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 ...

Differential effects of food restriction and warming in the two-spotted goby: I...

Climate change is a growing threat to marine organisms and ecosystems, and it is already modifying ocean properties by, for example, increasing temperature and decreasing pH. Increasing water temperature may also lead to an impairment of primary productivity and an overall depletion of available zooplankton. Understanding how the crossover between warming and zooplankton availability impacts fish populations ha...

Bioacessibility of Bioactive fish peptides incorporated in a RTE seafood product

Antioxidant and anti-inflammatory activities of ethyl acetate extracts of chub ...

The seasonal variation of key bioactivities in ethyl acetate extracts of chub mackerel (Scomber colias), an underutilised fish species, was evaluated through a complete monthly sampling. The phenolic content had a seasonal variation, ranging from 39 5 mg GAE/100 g ww (February) to 340 6 mg GAE/100 g ww (October). Ferric reducing antioxidant power (FRAP) increased from 1.3 0.4 lmol Fe2+ Eq/g ww (Jan uary) to 10....

Quantitative risk-benefit assessment of Portuguese fish and other seafood speci...

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 chemical composition and lipid profile of the chub mackerel (Scomber colias...

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...

Elemental composition and bioaccessibility of farmed oysters (Crassostrea gigas...

Free PMC article: https://www.ncbi.nlm.nih.gov/pmc/articles/pmid/31428337/; [Correction added on 8 July 2019, after first online publication: New affiliation was added for Jorge Machado, José Fernando Gonçalves, and Paulo Vaz‐Pires.]; The Pacific oyster (Crassostrea gigas) culture has been expanding, thereby leading to a greater importance of hatcheries. Broodstock conditioning is very important in the hatchery...

Effect of tidal environment on the trophic balance of mixotrophic hexacorals us...

Fluctuations of environmental factors in intertidal habitats can disrupt the trophic balance of mixotrophic cnidarians. We investigated the effect of tidal environments (subtidal, tidal pools and emerged areas) on fatty acid (FA) content of Zoanthus sociatus and Siderastrea stellata. Effect on photophysiology was also accessed as an autotrophy proxy. There was a general tendency of a lower percentage of zooplan...

Bioaccessibility of target essential elements and contaminants from Fucus spiralis

Fucus spiralis is an edible brown seaweed (SW) found in the Portuguese Coast that is still undervalued and not very well studied. However, SW are known to be nutritious and healthy foods, in part, for their potential to supply mineral nutrients to the body. Nevertheless, with the increasing levels of pollution in the coastal areas, SW can also accumulate some contaminants. Therefore, to expand the knowledge abo...

Bioaccessibility of target essential elements and contaminants from Fucus spiralis
