• Reading that cranberry juice may help prevent these infections, Buxton went on a regimen a year ago, and since then she's been infection-free.
• Here's a list of disease-fighting foods for men and women.
• Men who eat a lot of tomatoes, tomato sauce, or pizza smothered with the stuff may be giving themselves a hedge against prostate cancer.

• For best absorption, lycopene should be cooked with some kind of fat.
• Scientists are divided over reports that sperm counts have declined over the last 50 years and that environmental factors are to blame.
• A recent Harvard study finds that cruciferous vegetables, like broccoli, may protect against bladder cancer.
• If you want a healthy heart, spread your morning toast with peanut butter.
• Researchers from Pennsylvania State University compared the cholesterol-lowering effect of the American Heart Association's Step II Diet with a higher-fat diet based on peanuts.
• After 24 days both diets lowered "bad" LDL cholesterol.
• But the peanut plan also caused a drop in blood fats called triglycerides and did not decrease HDL, the "good" cholesterol.
• Research suggests that foods rich in potassium can reduce the risk of high blood pressure and stroke.
• The evidence is so convincing that the Food and Drug Administration recently allowed food labels to bear a health claim about the connection between potassium-rich foods and blood pressure.
• After analyzing the blood of over 13,000 people, scientists from the University of California, San Francisco, found that women who had lower levels of vitamin C were more likely to have gallbladder illnesses.
