Diet, Sunlight And Breast Cancer Risk

A study of eating patterns across different countries confirms an association between breast cancer and diets heavy in animal fats--and suggests that sunlight exposure may be protective against the disease by elevating the body's vitamin D supply.

However, the specific foods that might raise or lower breast cancer risk remain far from clear, according to Dr. William B. Grant, a researcher at the American Cancer Society (ACS) in Atlanta, Georgia. What's more, he said the only definite in terms of sun exposure is that too much of it can lead to skin cancer.

According to his analysis, diets marked by a higher fraction of animal products such as meat are associated with a higher risk of breast cancer. Diets rich in vegetables, fruits, grains and fish, on the other hand, were correlated with a decreased breast cancer risk.

The findings are published in the January 1st issue of the journal Cancer.
