Dairy Food, Calcium, and Risk of Cancer in the NIH-AARP Diet and Health Study

Abstract
Because of the benefit of calcium on bone health,1 dietary guidance has emphasized intakes of both calcium and dairy food. For example, the Institute of Medicine recommends 1200 mg/d of calcium for adults aged 50 years and older,1 and the 2005 dietary guidelines for Americans2 recommend 3 cups per day of fat-free or low-fat dairy food.
