Flaxseed lowers cholesterol levels

According to a study by Bahram Arjmandi, Ph.D., of Oklahoma State University, supplements of ground flaxseed lower cholesterol and reduce a heart disease-promoting protein in postmenopausal women. In the double-blind,crossover study, 38 women with extremely high cholesterol levels were given bread and muffins containing 38 g of either sunflower or flaxseed four daily. After six weeks, subjects were taken off the supplemented food for two weeks and then switched to food made with the other flour for six weeks. Flaxseed lowered total cholesterol by 6.9 percent and LDL cholesterol by 14.7 percent. Even more importantly, flax lowered levels of a protein called lipoprotein (a) which increases after menopause and causes atherosclerosis in several ways. This study demonstrates the first dietary approach to lowering Lp(a). According to Arjmandi, the potential effects of flaxseed on lowering blood cholesterol and Lp(a) in postmenopausal women have immense implications should this dietary source of PUFA (polyunsaturated fatty acid) and lifnan precursors be demonstrated effective. Only ground flaxseed has such effects; whole flaxseed is not digestible.
