Sweet, juicy, and so delicious – peaches are a reservoir of healthy goodness. A cup of this fruit has only 60 calories and provides a super sweet blast of vitamin C, fiber, potassium, and potent antioxidant carotenoids. We already know that peaches are great for heart health, but they may prove to be most beneficial for breast cancer protection. A recent study found that an extract from peaches killed even the most aggressive breast cancer cells in the test tube.  ( Journal of Agricultural and Food Biochemistry, June 2010)
