A diet based on fish can also be dangerous

Heavy metals such as cadmium, chromium, mercury, lead, and nickel can be toxic even in small amounts and pose a serious health risk. These metals can enter the body of fish as a result of contamination of the marine environment, so the consumption of fish indirectly affects us as well.

Although, according to studies, domestic fish are less exposed to heavy metal pollution, a significant part of the global fish market comes from regions where this problem is more serious. Consumers should find out about the origin of fish and their potential risks.

In terms of risk levels, we distinguish several categories. The very low risk group includes, for example, wild Pacific and Alaskan salmon, mussels, shrimp, and oysters, while the high risk group includes species such as swordfish, tilefish, marlin, shark, bluefin tuna, and king mackerel. It is especially important that pregnant and lactating mothers avoid the consumption of fish classified in the high-risk group.
