Men who pop too many vitamins in the hope of improving their health may in fact be raising their risk of the deadliest forms of prostate cancer, especially men with a family history of the disease. Researchers at the National Cancer Institute found that men who exceeded the recommended dose -- taking more than seven multivitamins a week -- increased the risk of advanced cancer by about 30%. "We didn't see any relationship with overall prostate cancer," said Dr.

Dr. Luigi Di Bella, 90, the Italian physician known for his controversial, unsuccessful attempts to cure cancer, died Tuesday in Modena, Italy, of respiratory problems. Although not trained in cancer research, Di Bella began experimenting with melatonin, generally considered a sleep aid, to treat cancer in the 1960s. Over the years, he developed Di Bella Multitherapy, a drug cocktail of up to 100 chemicals including melatonin, beta-carotene, Vitamin D and shark cartilage.

Watermelons stored at room temperature deliver more nutrients than refrigerated or freshly picked melons, U.S. Department of Agriculture scientists say. Penelope Perkins-Veazie and Julie Collins of the USDA's South Central Agricultural Research Laboratory in Lane, Okla., looked at carotenoids -- antioxidants that can counter the damage caused by sun, chemicals and day-to-day living.

HIV-positive women who are breastfeeding should not be given vitamin A supplements because it increases the risk of transmitting the AIDS virus to their infants, researchers said Thursday. Mother-to-child transmission of HIV has been largely controlled in the United States and other developed countries through the use of antiretroviral drugs, but is a major problem in the developing world. In 2008, there were 430,000 new HIV infections in infants, most of them in sub-Saharan Africa, and breast feeding accounted for more than 95% of them.

A decade ago, antioxidants -- nutrients such as beta carotene and vitamins C and E -- were taking the nutrition world by storm. These free-radical fighters, medical experts predicted, would extend human life by protecting us from environmental hazards, cancer and heart disease. Antioxidants began making headlines in the early 1990s, when several large medical studies showed lower rates of cancer in people who took vitamin E and beta carotene.
