Mercury on our plate?
Is it healthy to eat fish?
Of course, but several factors have to be considered. Phillipe Emanuelli, in his book Fish, tells us:
Lean fish meat is low in calories; the fatty fish is oily, but this particular type of polyunsaturated fats (omega-3), promote protection of the cardiovascular and nervous systems.
The whole is a source of quality protein, a unique cocktail of minerals – phosphorus, calcium, sodium, iodine – that are easily metabolized by our body.
If we add a significant level of vitamins A, D or B, especially B12, fish certainly is good for health.
But what about pollution? Many marine sites present in the analyzes a true catalog of all that the industry discards and is not biodegradable, in particular the contaminants – pesticides, antibiotics, estrogens, antidepressants, anabolics, dioxins, PCBs, bisphenol, microplastics, microcomputer components, creams And solar oils – and, of course, some heavy metals – lead, cadmium and methylmercury.
These contaminants and heavy metals accumulate in the main predators, the last link in the food chain (tuna, swordfish, shark).
This contamination is very widespread and very few sites are saved. On the other hand, the majority of the fish are migratory, and frequent throughout their life numerous biotopes sensitive to the contamination.
What to do then?
Avoid consuming large predators, and moderately eating smaller species. Some countries have already made official recommendations that limit the consumption of fish in general, and drastically for pregnant women, young children, adolescents …
Let go of the carnivorous fish of intensive aquaculture. If you are not sure of its origin, limit your intake to a few hundred grams a week, and avoid the fatty parts of the fish – the liver, the skin – where the contaminants can accumulate.
