Walnuts When it comes to nuts, the walnut is the king. It’s a great source of the healthy omega-3 essential fatty acids, which have been found to protect the heart, promote better cognitive function, and provide anti-inflammatory benefits for asthma, rheumatoid arthritis, eczema and psoriasis. Walnuts also contain the antioxidant compound ellagic acid, which is known to fight cancer and support the immune system. But that’s not all—in a study in the August 2003 issue of Phytochemistry, researchers identified 16 polyphenols in walnuts, including three new tannins, with antioxidant activity so powerful they described it as “remarkable.” Walnuts are incredibly healthy for the heart. A study in the April 2004 issue of Circulation found that when walnuts were substituted for about one-third of the calories supplied by olives and other monounsaturated fats in the Mediterranean diet: * Total cholesterol and LDL (bad) cholesterol were reduced * The elasticity of the arteries increased by 64 percent * Levels of vascular cell adhesion molecules, which play a major role in the development of atherosclerosis (hardening of the arteries), were reduced
