Healthy fats, Omega-3s, are found in green leaves and fish (because they eat green plants/phytoplankton and seaweed.) Read more in the Prevention Magazine article here. Today, we are eating fewer nutrient high green leaves and more seeds both in food and also meat we consume (cows are now fed on a diet of grain and soy rather than grass).
The American Heart Association recommends eating fish such as salmon, albacore tuna, and mackerel twice a week. Avoid farmed fish that may be fed corn and soy. Walnuts are also rich in a form of Omega-3 fatty acid.
