NEW YORK: Led by Harvard TH researchers This large-scale study looked at 182,145 women aged 27 to 59 participating in the Long-Term Nurses' Health Study and at the Nurses Health Study II, two of the largest surveys of women's risk factors.

"This research provides the most complete picture of the importance of consuming large amounts of fruits and vegetables for the prevention of breast cancer," commented first author Maryam Farvid.
Earlier researchers found that greater fiber consumption is associated with a reduced risk of breast cancer.But the benefits of fruits and vegetables found in this study seemed to be independent of their fiber content, suggesting that other components, such as antioxidants and other micronutrients, may also be important in reducing the risk of breast cancer.
Lots of fruit "s and vegetables are associated with many other health benefits, our results could encourage women to increase their consumption of fruits and vegetables," said lead author Heather Eliassen
