Soy Benefits Heart Health in Healthy Young Men
 (NY Reuters Health, 2/28/06)

Alison Duncan of the University of Guelph in Ontario, Canada, and team, gave 35 healthy young men either milk proteins, low-isoflavone soy proteins or high-isoflavone soy for eight-week periods. The team assigned the supplements in random order, separating each 8-week period by a one-month break. The investigators measured blood levels of various lipids and found that the ratios of total cholesterol to HDL ("good") cholesterol and LDL ("bad") cholesterol to HDL were lower when subjects were taking either soy supplement, as compared to the milk protein. The scientists concluded that soy proteins reduce lipid levels; although isoflavones apparently do not affect the results.
