Omega-3 fatty acids are all the rage among health food lovers. But unlike other claims you’ll find in the supermarket aisles, this is one you should actually pay attention to. "Fatty fish and bivalves are the top sources of the long-chained omega-3 fats," says Dr. Ramsey. A deficiency of this critical fat can result in major mental problems like fatigue, memory loss, mood swings, and depression.
Dr. Ramsey recommends getting your omega-3s through two weekly servings of mussels, oysters, or salmon. And unless you shun seafood altogether, opt to get your omega-3s through food, not supplements, especially if you're an older adult.
You really should eat pumpkin seeds more often than on Halloween. In Dr. Ramsey's case, they're a part of his practice. "I prescribe a lot of pumpkin seeds, as they are full of tryptophan, magnesium, fiber, and zinc," important minerals for brain function.
