|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.|
