Fish is the best source of omega-3s. Current research suggests that you eat 1-2 servings per week (a serving being about 3-4 ounces) of fatty fish such as salmon, sardines, mackerel or light tuna. There’s a caveat here though…if you are pregnant or planning to get pregnant, breast feeding or if you have children under 12, you should only consume up to 2 servings a week (3 ounce portions) of fish and be sure to avoid large, predatory fish with higher mercury levels such as swordfish, tilefish or king mackerel.

Have you heard that you can also find these omega-3 fats in plant foods? Plant sources contain what’s called ALA, another omega-3 fat.. Sources of ALAs are ground flaxseed, walnuts and canola oil.
