A recent study conducted by Italian researchers revealed that increased intake of the antioxidant vitamins C and E can reduce the risk of kidney cancer by 28 and 44 percent respectively.

Researchers found that more than 80 percent of all kidney cancers are caused by renal cell carcinoma (RCC). They also revealed that an intake of more than 186 micrograms per day of vitamin C was associated with a 44 percent reduced risk of renal cell cancer, compared to those who took the average daily amount of 89.4 micrograms

Research by scientists at the University of Medicine and Dentistry of New Jersey, has shown that levels of Vitamin E in women during pregnancy were directly related to the birth weight of their babies. More precisely, higher plasma concentrations of one form of vitamin E - alpha-tocopherol - were positively related to increased fetal growth.

The researchers followed 1,231 women and measured their plasma concentrations of alpha-tocopherol at week 1 and week 28 of their pregnancy. Researchers found that the women who had a higher level of the vitamins during the tests tended to have bigger children

Medical data indicates that approximately 30 percent of breast cancers have high levels of a HER2, a human epidermal growth factor receptor. Research conducted by Griffith University's School of Medicine has found that these breast cancer cells may be fought with a precursor of vitamin E.

Eating vegetables seems to slow mental decline, a new study shows. In a study of nearly 2,000 Chicago-area men and women age 65 and older, those who ate more than two servings of vegetables per day appeared about five years younger mentally.
