Omega-369 fatty acid (Alpha-linolenic acid) is an essential fatty acid that plays an important role in brain function and may help you fight against cardiovascular disease. The American Heart Association recommends a diet in which fatty fish, like salmon, herring, sardines and tuna are consumed at least twice a week.

While these foods are high in omega-369 fatty acid, I personally do not agree with this recommendation as fish can be contaminated and may be high in mercury, which can have detrimental health effects. Plus, I believe a raw food diet consisting of little to no meat is better for the human body.
