I like this research information so much that I had to send you another article today!
I often meet men who tell me that they forget things like keys and dates and times. Daily supplements of soy isoflavones could help boost a man’s mental function and memory, according to findings of a small study from Australia.
Men receiving daily supplements of the isoflavones performed significantly better in tests of their working memory, report scientists from the University of South Australia and the University of Adelaide in the British Journal of Nutrition.
Researchers, led by Peter Howe, recruited 34 healthy men to participate in their 12-week double-blind, placebo-controlled cross-over trial. The men were randomly assigned to receive a daily dose of 116 mg soy isoflavones, providing 68 mg daidzein, 12 mg genistein, and 36 mg glycitin, or placebo for 6 weeks. They were subsequently crossed-over to the other intervention for the following 6 weeks.
Tests of memory, mental function, and visual-spatial processing performed before and after the supplementation period showed that the isoflavone supplements were associated with improved spatial working memory; “a test in which females consistently perform better than males”, said the researchers.
There is so much controversy about soy protein in the news, but consistent research shows that moderate soy consumption appears to have a myriad of health benefits.
Best of health again!
