Harvard study sees a lifelong high-fiber habit as a particularly powerful ally
- The apparent protective effects of fiber were linked most strongly to diets rich in both fruits and vegetables.
- Women eating high-fiber diets from their teen years on were 12-19 percent less likely to develop breast cancer at any time.
- Feasting on fiber early in life may lower overall risk by 16 percent, and the risk of pre-menopausal breast cancer by 24 percent.
- For each additional 10 grams (1/3 ounce) of fruit and vegetable fiber a young woman eats daily, her lifelong risk for breast cancer drops by 13 percent.
- Diets that included ample fiber from fruits or from both fruits and veggies reduce the risk of breast cancer.
- Vegetables alone do not exert significant protective effects … a finding that contradicts the results of the recent study from Harvard.
