Heart-Healthy Recipes
Although walnuts boast heart-healthy oil like most nuts, they have an added edge. Most nut oil is monounsaturated, but walnuts primarily contain the polyunsaturated variety. In fact, they're the only nuts -- and one of the few foods -- that offer appreciable amounts of a crucial type of polyunsaturated fat called alpha-linolenic acid, or ALA, which is an omega-3 fatty acid. ALA protects the heart in several ways: It improves your ratio of HDL (good) to LDL (bad) cholesterol, and it reduces inflammation, helping to block the conversion of cholesterol into harmful, artery-clogging plaque.
