There are many types of fish in the sea. Fish are rich in omega-3 fatty acids, which are important for brain, heart, joint, skin and cell membrane health. Unfortunately, most of us are not getting enough omega-3’s through our diet. Adding fish 2-3 times a week can be a healthy way to boost your omega-3 levels and protein intake. There is a lot of controversy around eating fish due of the high mercury content of our oceans. Mercury finds its way into fish, particularly larger fish like swordfish, tuna and shark. As a general rule of thumb, the smaller the fish, the less mercury it’s likely to have. When selecting fish, choose sustainabily caught over farmed, as farmed fish are often fed grains which lower their omega-3 content. Additionally, stay away from toxic or endangered fish. Clean Fish and the Natural Resources Defense Council are good resources for learning more about selecting healthy fish. You can download the NRDC’s ‘Mercury in Fish’ wallet card to help you shop for sustainable and healthy fish.
