What a great question! Fish is an important part of a healthy diet. Fish and other seafood have nutrients that are good for you like omega-3 fatty acids, vitamin D, and many are high in protein and low in saturated fat.
Additionally, there have been some studies that show that eating fish once or twice a week may lower your risk of developing stroke, depression, Alzheimer's disease and other chronic conditions.
Mercury is an issue in fish and seafood, but knowing which fish have lower mercury levels than others is good way to still keep fish in your diet.
