At least seven prior studies have linked prostate cancer risk to intake of dairy foods, but the roles of different components, such as calcium, vitamin D and other potential constituents, are unclear.
Reporting in the American Journal of Clinical Nutrition, Tseng and colleagues at the National Cancer Institute studied the relation of dairy intake to prostate cancer risk in 3,612 men with a mean age of 57 years who were followed in NHANES (National Health and Nutrition Examination Survey) surveys from 1982-1992.
