8 Types of Fish to Avoid in Your Diet

⚠️ Bluefin tuna: a species in peril.
A symbol of Japanese cuisine, bluefin tuna is now threatened with extinction . A victim of devastating industrial fishing, it is among the critically endangered species . To protect the oceans, opt instead for albacore or yellowfin tuna , sourced from certified sustainable fisheries .

⚠️ Tilapia: A Misleading Alternative
Often touted as a “light and healthy” fish, tilapia suffers from mass production in overcrowded, artificially fed tanks. The result: flesh low in nutrients, an imbalance between omega-6 and omega-3 fatty acids, and an increased risk of inflammation. It is therefore far from being a healthy choice.

⚠️ European eel: ecological and health hazard.
The eel is a species in dramatic decline , a victim of overfishing and pollution. Its flesh accumulates heavy metals and PCBs , persistent toxic substances. Consuming it endangers both biodiversity and your health .

⚠️ King mackerel: too much mercury.
King mackerel , larger than Atlantic mackerel, contains high levels of mercury , a dangerous neurotoxin , especially for pregnant women and children . Opt for smaller mackerel, which are naturally less contaminated.

⚠️ Factory-farmed salmon: an underestimated risk.
Behind its healthy image, conventionally farmed salmon hides a disturbing reality: excessive stocking density, antibiotic use , and artificial feeding. Its flesh can contain up to 16 times more contaminants than wild salmon. Organic or wild salmon remains the best option.

⚠️ Swordfish: a toxic predator.
As a top predator in the marine food chain, swordfish accumulates large amounts of mercury and other pollutants. Regular consumption poses neurological risks, particularly for pregnant women and children.

⚠️ Ray: a fragile species. Often
overfished , rays reproduce slowly and their populations are collapsing. Some species are already classified as endangered. To preserve ecosystems, it is best to exclude them from your diet.

💚 4 Fish to Choose for Your Health and the Planet
🐠 Sardines : rich in omega-3, low in contamination, and very affordable.
🐟 Atlantic mackerel : a source of essential fatty acids, low in heavy metals.
🐡 Wild salmon : nutritious, rich in omega-3, and low in pollutants.
🐙 Herring : a perfect balance of protein, vitamin D, and protective fatty acids.
