A decades long study (from the Harvard T.H. Chan School of Public Health) had results that many women may find reassuring - because there may be something they can do to increase their odds of preventing breast cancer. The study found that women who ate more than 5.5 servings of fruits and vegetables each day had an 11% lower risk of breast cancer than those who ate 2.5 or fewer servings daily.
While the findings support eating a variety of fruits and vegetables, they found that cruciferous (broccoli, cabbage, cauliflower) and yellow/orange vegetables (e.g. winter squash) appear to be especially beneficial in reducing the risk of breast cancer, especially those that are more aggressive tumors. The association between amount of fruits and vegetables eaten daily and breast cancer appeared to be strongest 8 or more years before cancer diagnosis - meaning fruit and vegetable intake now appears to have effects many years later.
By the way, the researchers found in earlier research that a higher fiber intake (especially during adolescence and early adulthood) was also associated with a lower beast cancer risk. Now let's see if these findings hold up over time in other studies. From Science Daily:
Women who eat a high amount of fruits and vegetables each day may have a lower risk of breast cancer, especially of aggressive tumors, than those who eat fewer fruits and vegetables, according to a new study led by researchers from Harvard T.H. Chan School of Public Health. In their findings, cruciferous vegetables such as broccoli, and yellow and orange vegetables, had a particularly significant association with lower breast cancer risk. ...continue reading "Eating Lots of Fruits and Vegetables Associated With a Lower Breast Cancer Risk Years Later"
