Soy and the aging brain
Soy may be protective when it comes to brain health.
In Asia, where people consume up to 40 times more soy than we do, science indicates there is an inverse relationship between soy consumption and brain decline. This relationship prompted researchers to take a closer look at the effects of soy on the aging brain.
In a meta-analysis, scientists found soy's potent antioxidants, isoflavones, and phytoestrogens had a positive effect on brain health for post-menopausal women. Those who took soy isoflavone supplements enjoyed both improved visual memory and overall cognitive function.
