• Increased aggressive behavior and decreased affiliative behavior in adult male monkeys after long-term consumption of diets rich in soy protein and isoflavones.: Estrogen produced by aromatization of gonadal androgen has an important facilitative role in male-typical aggressive behavior that is mediated through its interaction with estrogen receptors (ER) in the brain. Isoflavones found in soybeans and soy-based dietary supplements bind ER and have dose- and tissue-depende nt effects on estrogen-media ted responses. Yet, effects of isoflavone-ric h diets on social and aggressive behavior have not been studied. We studied the effects of long-term (15 months) consumption of diets rich in soy isoflavones on spontaneous social behavior among adult male cynomolgus macaques (Macaca fascicularis) (n = 44) living in nine stable social groups. There were three experimental conditions which differed only by the source of dietary protein: casein and lactalbumin (no isoflavones), soy protein isolate containing 0.94 mg isoflavones/g protein, and soy protein isolate containing 1.88 mg isoflavones/g protein. In the monkeys fed the higher amount of isoflavones...

• Brain Aging and Midlife Tofu Consumption -- White et al. -- Journal of the American College of Nutrition: The results presented here demonstrate an association of self-reported tofu consumption frequency in midlife with functional and structural indicators of brain aging. Because the effects were apparent at relatively modest levels of intake (two or more servings weekly), an adverse pharmacologic mechanism seems more likely than a nutritional pathogenesis. While our study cannot directly impune a specific constituent with certainty, isoflavone phytoestrogens are obvious candidates. We hypothesize that regular dietary exposure to soy isoflavones over many years during middle life may be associated with the appearance of accelerated brain aging in later life attributable to chronically sub-optimal neural plasticity. The specific means by which soy phytoestrogens might exert such influence could involve competition with endogenous estrogens for estrogen receptors in neurons and/or reduction in estrogen concentration in the brain by inhibition of the aromatization of androgens. Alternatively,
• Health Benefits of Soy Appear Limited, New Review Concludes - Office of Dietary Supplements National Institutes of Health - October 2005: Overall, the report concluded, available studies were limited in number, of poor quality, or their duration was too short to reach definite conclusions. According to Office of Dietary Supplements (ODS) Director Paul M. Coates, PhD, "This report shows us that there's much more to learn about soy, and it provides suggestions for future research on soy's health effects that we and NCCAM will carefully review." In particular, studies that substitute practical amounts of soy into people's diets would better address the question of whether we should make the effort to consume it.
