Book I'm Reading: "This Is Your Brain on Food" by Uma Naidoo

Omega-3s are important for normal body metabolism—they are a vital part of cell membranes and provide the starting point for making the hormones that regulate blood clotting, contraction and relaxation of artery walls, and inflammation. But since we cannot produce them on our own, we must get our omega-3s from our diet.

You can also improve your ratio of omega-6 to omega-3 by using certain oils in your cooking. For instance, rather than using plain vegetable oil, which is extremely heavy in omega-6, use canola oil.
