As someone who cooks fish for the family almost every week, I always tell people to check the store shelves carefully for safer options... Which fish have the least mercury?? Salmon, canned light tuna, tilapia, and cod are your best friends at the supermarket store today!!! These choices are low in heavy metals and great for a healthy diet without any risks... I always buy wild-caught salmon or simple frozen cod fillets because they are safe, affordable, and easy to prepare for everyone at home!
