A recent Harvard study examined the association between fruit and vegetable consumption and breast cancer. The researchers drew participants from eight separate studies that spanned four countries and involved more than 350,000 women. Women who consumed the highest amount of fruits and vegetables were compared with those who consumed the lowest amount. The analysis revealed no significant difference in the risk of breast cancer between the two groups. The research team also did not find any specific groupings of fruits or vegetables that had strong associations with breast cancer risk reduction. This was the largest study of diet and breast cancer to date. The study findings appeared in the February 14, 2001, edition of the Journal of the American Medical Association.
