Almonds are high in monounsaturated fats, the same type of health-promoting fats as are found in olive oil, which have been associated with reduced risk of heart disease.
In addition to their cholesterol-lowering effects, almonds' ability to reduce heart disease risk may also be partly due to the antioxidant action of the vitamin E found in the almonds, as well as to the LDL-lowering effect of almonds' monounsaturated fats. (LDL is the form of cholesterol that has been linked to atherosclerosis and heart disease). When almonds are substituted for more traditional fats in human feeding trials, LDL cholesterol can be reduced from 8 to 12%.
In addition to healthy fats and vitamin E, a quarter-cup of almonds contains almost 99 mg of magnesium (that's 24.7% of the daily value for this important mineral), plus 257 mg of potassium. WHF
