Study: Healthy diet may halt breast cancer: Up to 50 percent of cases could be prevented A landmark report on diet and cancer risk from the American Institute for Cancer Research (AICR) estimates that 33 percent to 50 percent of breast cancer could be prevented by a healthy diet and lifestyle, particularly if begun before puberty and continued throughout life. A NEW REVIEW of this question in the European Journal of Cancer, concludes that in 17 studies, women who consumed the most vegetables faced a 25 percent lower risk of breast cancer than those who ate the least. Another study, reported in Nutrition and Cancer, found that women who ate the most vegetables had a 60 percent lower risk than those who ate the least. The beta-carotene and vitamin C in vegetables seem to be part of this protection, but research shows vegetables contain thousands of natural phytochemicals that work in many different ways to combat cancer. One such group, called indoles, is found in cruciferous vegetables like broccoli, cabbage and cauliflower, and seem to boost enzymes that make estrogen less effective at promoting breast cancer.
