Here's little secret your doctor probably never told you: a simple fish oil could be the key ingredient to a long, happy life. Omega-3. This miracle fat  might not only prevent heart attacks and help you avoid a stroke — it could also protect you from depression and other brain disorders.

Mountains of evidence clearly show that special fats known as Omega-3 Fatty Acids (or N-3 fats) greatly enhance the health of the brain, as well as virtually every cell in the body. Omega-3 fats are a group of polyunsaturated fats commonly found in plants, fish, algae and flaxseed. These polyunsaturated fats are the "good guys," while trans fatty acids (the partially hydrogenated fats found in vegetable oils) and omega-6 fats are the "bad guys." One study found that consuming more Omega-3 fats actually boosted the brain's levels of depression fighting serotonin and made brain cell membranes more effective, causing them to work more like young, healthy brain cells.
