8 Fish Species to Ban from Your Diet for Your Health and the Ecosystem

Tilapia: beware of preconceived ideas

Often touted as an economical and practical option, tilapia hides a less than rosy reality. Its farming, often carried out under high-density conditions using artificial feed, negatively impacts its nutritional quality. Particularly low in omega-3 and presenting an imbalance between omega-6 and omega-3, its regular consumption could even promote inflammation.

European eel: double punishment

This fish faces two major problems: its alarming scarcity and its contamination with persistent pollutants like PCBs and heavy metals. These toxic elements accumulate in its flesh, making it unsuitable for consumption.

King mackerel: beware of mercury!

Less common than its cousin, the Atlantic mackerel, king mackerel has worrying levels of mercury. This heavy metal, which is particularly harmful to neurological development, makes it a risky choice, especially for pregnant women and young children.

Farmed salmon: between benefits and risks

While salmon is renowned for its nutritional benefits, intensive farming methods raise questions. Overcrowding in fish farms promotes disease and often leads to heavy use of medication. Choose wild-caught salmon or those from certified responsible farms.
