Fish is healthy – is that right?

• In itself, fish is healthy. Almost every variety has so many important ingredients for humans that it doesn’t matter which fish you eat. Above all, protein, vitamin B1 and B12, but also vitamin D are contained in large quantities in fish. There are also omega-3 fatty acids, which also have positive effects on your body.

• However, there is also a disadvantage: Due to the pollution of the seas, many fish are contaminated with toxins. These are mainly lead PCB (polychlorinated biphenyls), and mercury.

In particular, shark, eel, butter mackerel, loach, halibut, pike, swordfish, monkfish, and tuna are usually more heavily contaminated.
