With half the calories of salmon, Barramundi is still packed with Omega-3 fatty acids (known to promote both brain and cardiovascular health) and boasts 21 grams of lean protein in a four-ounce serving.
Mercury and PFOS cannot be removed through cooking or cleaning -- they get into the flesh of the fish. You can reduce the amount of other contaminants like PCBs by removing fat when you clean and cook fish.
