Avid consumption of foods high in isoflavones may help guard against the occurrence of breast cancer in women.
This study conducted a meta-analysis on the findings of previously published studies that focused on the association between dietary intake of isoflavones and a woman's propensity to develop breast cancer. Data from 24 studies were analyzed for this meta-analysis.
Researchers discovered that daily consumption of 10 mg of isoflavones from food sources can reduce a woman's chances of getting breast cancer by as much as 11.7%. The researchers concluded that "present evidence demonstrated that taking in dietary isoflavone is helpful in reducing the breast cancer risk."
