Veggies Cut Breast and Prostate Cancer Risk
Vegetables and fruits rich in beta-carotene can cut the risk of breast and prostate cancer. The findings were based on 83,234 participants in the Harvard Nurses' Health Study, and showed a particular benefit for younger women and those at risk due to a family history of cancer or regular alcohol use.

A study of 3,643 male physicians showed that men with the lowest levels of beta-carotene in their blood had a 45 percent greater risk of developing prostate cancer, compared with men with the highest blood levels. Lycopene, a cousin of beta-carotene that gives the red color to tomatoes and watermelon, is also associated with reduced risk, and carotenoid-rich foods are associated with better cancer survival. Here are some healthy sources of beta-carotene: broccoli, brussels sprouts, carrots, grapefruit, fresh spinach, and sweet potatoes.
