Fish can be an excellent part of a healthy diet, providing important nutrients like omega-3 fatty acids which can lower your risk for diseases like cancer, Alzheimer’s, cardiovascular disease, and dementia, age-related macular degeneration, and rheumatoid arthritis, among others. However, there are certain fish you should never eat. Unfortunately, because of human industrial activity like coal-fired electricity generation, smelting, and the incineration of waste, large amounts of mercury are ending up in our waterways, and subsequently, the fish that swim in them. As this mercury gets into the marine food chain, it “bioaccumulates.”
