Soy supplements taken daily don't improve the overall thinking abilities of older women, according to a new study.
"There are no substantial cognitive effects, positive or
negative, from soy protein consumption in women past menopause," said
researcher Dr. Victor Henderson, professor of health research and policy
and neurology and neurological sciences at Stanford University.
In the study, published June 5 in Neurology,
Henderson and his team evaluated 350 postmenopausal women, aged 45 to
92. The researchers randomly assigned the women to take 25 grams of soy
protein a day or a milk protein placebo. The soy and placebo were given
in powder or bar form.
The study, funded by the U.S. National Institutes of Health, is called the Women's Isoflavone Soy Health Trial.
Isoflavones in soy are estrogen-like compounds. Some women choose them
as an alternative to hormone therapy to relieve hot flashes and other
symptoms of menopause.
