(Ivanhoe Newswire) -- The American Heart Association recently
re-evaluated a statement published by an association committee in 2000 stating
soy protein is good for the heart.
The committee analyzed 22 studies on soy products and found soy actually offers
very few heart benefits. Researchers say soy, taken in large amounts, only
slightly decreases low-density lipoproteins, or bad cholesterol, but doesn't
show any other significant benefits for the heart -- or the rest of the body.
It agreed soy may still prove a healthy alternative to high-fat foods, but
disagreed on its ability to slow postmenopausal bone loss.
Researchers have not determined if using soy to treat breast, endometrial and
prostate cancer is safe, nor have they established its effectiveness in
combating hot flashes or osteoporosis. Frank M. Sacks, M.D., professor of
nutrition at the Harvard School of Public Health in Boston, says, "There is
nothing proven in this regard." He also says, "There is little effect on hot
flashes and the osteoporosis prevention effects are mixed."
Considering adverse effects on many people, the committee says the use of
isoflavone supplements is not recommended.
