High consumption in France
Although the body eventually eliminates 95% of mercury naturally, chronic exposure remains a concern. In France, the average mercury consumption reaches 267 µg per week. A rather worrying level, because it far exceeds the maximum recommended dose of 200 µg/week by the WHO. Hence the concern for certain species of fish.
Marie Martin, in the scientific journal Analytical and clinical toxicologyexplains that “the adverse health effects of consuming food or water contaminated with metals vary depending on the quantity consumed, duration of exposure, age ».
A fish dangerous for health
Among the most consumed fish in France, sea bream is distinguished by its tender flesh and delicate taste. However, it is on the list of species likely to contain traces of mercury. Although it is less contaminated than predators like swordfish or tuna, its excessive consumption can represent a danger.
Low in fat and high in omega-3sea bream remains an interesting choice for a healthy diet, but it should be consumed in moderation. Pregnant women, young children and immunocompromised people should limit their consumption of this fish to once a week.
“If I were inclined to recommend the wild fish in food for their omega-3 content, I now advise patients to be careful. » underlines the dietitian nutritionist Alexandra Retion.
