Eating fish for health reasons may not be as beneficial as it seems due to the significant levels of heavy metals found in them. Even small fish like anchovies and sardines contain mercury, arsenic, and cadmium. Shellfish, like oysters and mussels, also have high levels of cadmium. This heavy metal contamination is a problem not only in fish but also in oats and grains. It's important to be aware of your heavy metal status, and conducting a blood test can give you a sense of your levels.
