HEALTH UPDATE: soya not so smart for lowering breast cancer risk

At least one third of women at high risk for breast cancer regularly consume soya-based foods - but this may not be a good idea, researchers say.
While the benefits of soya consumption for cardiovascular health have been confirmed, there is no evidence that soya foods improve breast health, particularly in non-Asian women, Dr Carolyn Y. Fang of the Fox Chance Cancer Center in Cheltenham, Pennsylvania, and colleagues note.
In fact, they point out in an article in the Journal of the American Dietetic Association, there is some evidence that high soya consumption could actually increase breast cancer risk among US women.
Fang and her team interviewed 452 women with family histories of breast cancer about how frequently they consumed soya and why.
