Soy Foods Lower Cholesterol Significantly

Nov 18, 2004

This study included 1033 pre- and postmenopausal women. Blood samples were obtained and plasma total-cholesterol, LDL, and HDL concentrations were measured. The women consumed radically different amounts of soy. Those women who consumed greater than 6 grams of soy protein a day had a 12.4% lower level of LDL-cholesterol than women who consumed the lowest levels. The study is published in the November 2004 issue of The American Journal of Clinical Nutrition.

Unfortunately I couldn't get the level of soy isoflavones for you - a second soy constituent that lowers dangerous LDL-cholesterol.

Quercetin Protects Brain Cells from Alzheimer's Type Damage

A research team from Cornell University soaked rat brain cells in Quercetin, a strong polyphenolic antioxidant, or vitamin C (a milder antioxidant, but with very important physiological activity), or applied no antioxidant. The brain cells were then exposed to hydrogen peroxide mimicking a type of damage that would occur in Alzheimer's disease. Brain cells that were treated with Quercetin had significantly less damage than those not treated with an antioxidant or with vitamin C. The study is published in the December 1st 2004 issue of the Journal of Agricultural and Food Chemistry.
