Cranberry Juice -- Drinking 10 ounces of cranberry juice each day reduces the chance of getting a urinary tract infection, according to a study published in the Journal of the American Medical Association. New lab studies indicate cranberry components -- flavonoids -- may be useful in battling cancer and gum disease.
Orange Juice -- One 8-ounce glass of OJ provides 25 percent of the recommended daily level of folic acid, which women need to prevent certain birth defects. That same amount of juice supplies 100 percent of the recommended daily amount of vitamin C. Some fortified juices boost vitamin C levels even more. Others contain calcium.
Grape juice -- Beverages from red grapes contain resveratrol, a cancer-fighting substance that seems to work as an anti-inflammatory agent and may also keep early cancer cells from growing. Like red wine, grape juice has some heart-protecting benefits.
