People who love sushi don’t want to hear about tuna’s negative effects on the body. But the news is evident. Tuna, particularly canned tuna, is associated with mercury. Tuna like bigeye and albacore may have healthy fats to offer our diet, but their high mercury content can spell trouble for cognitive function. Mercury and other heavy metals can significantly impact brain health, so we must strive to eliminate and certainly reduce them from our diets. While tuna has lots of mercury, other types of fish do not. As you lower your tuna intake, try to eat more fish like wild salmon and trout.
