NUTS. Anti-cancer and heart-protective properties. A key food among Seventh-Day Adventists, known for their low rates of heart disease. Walnuts and almonds help reduce cholesterol, contain high concentrations of antioxidant oleic acid and mono-unsaturated fat, similar to that in olive oil, known to protect arteries from damage. Nuts generally are high in antioxidant vitamin E, shown to protect against chest pain and artery damage. Brazil nuts are extremely rich in selenium, an antioxidant linked to lower rates of heart disease and cancer. Walnuts contain ellagic acid, an antioxidant and cancer-fighter, and are also high in omega-3 type oil. Nuts, including peanuts, are good regulators of insulin and blood sugar, preventing steep rises, making them good foods for those with glucose intolerance and diabetes. Peanuts also are estrogenic. Nuts have been found lacking in the diets of those who later develop Parkinson's disease. Prime cause of acute allergic reactions in susceptible individuals.
