A two and half years study finds no improvement from eating soy as a menopause treatment for cognitive function including what many menopausal women label as “brain fog”.
Brain fog often times refers to the common menopausal symptoms including difficulty in remembering daily events and activities. If you are experiencing memory loss or brain fog as part of your menopausal symptoms be aware that the addition of soy to your diet will not help. Although their were no harmful effects, (stick to organic soy) this study showed no improvements for visual memory and thinking ability.
Dr. Victor Henderson of Stanford University in Palo Alto, Calif., and his co-authors randomly assigned 313 post-menopausal women aged 45 to 92 to take either 25 grams of soy protein daily or a placebo with milk protein that looked and tasted the same.
The participants were given tests that measured their memory and other thinking abilities at the start of the study and again after 2.5 years.
“For healthy post-menopausal women, long-term dietary soy isoflavone supplementation in a dose comparable to that of traditional Asian diets has no effect on global cognition but may improve visual memory,” Henderson and his co-authors concluded in Tuesday’s issue of the journal Neurology.
This study was supported by the U.S. National Institutes of Health, the National Center of Complementary and Alternative Medicine, the Office of Dietary Supplements and the Office of Research on Women’s Health.
