Flaxseed contains alpha-linolenic acid which lowers serum cholesterol and reduces platelet aggregation. Ten grams of flaxseed contains 4 grams of dietary fiber which also helps lower cholesterol and increases fecal elimination of bile acids. Flaxseed is an indirect food source of lignans which alter estrogen metabolism to produce less active estrogen metabolites. Flaxseed improves renal function by decreasing blood viscosity, reducing serum cholesterol and reducing inflammatory response.
