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.
