A high-dairy diet may “modestly reduce” the risk of breast cancer in postmenopausal women, according to a study from the American Cancer Society.

The study, published in the December 2005 issue of Cancer Epidemiology Biomarkers and Prevention, included 68,567 postmenopausal women who did not have breast cancer when the study began. Participants completed a detailed survey about their diet, vitamin and mineral supplement use, medical history and lifestyle between 1992 and 1993. The researchers followed the women through August 2001. By then, 2,855 of the participants had developed breast cancer.

 Women who had the highest dietary calcium intake (greater than 1,250 milligrams of calcium per day) were at a lower risk of breast cancer than women who ate the lowest amount of dietary calcium (500 mg or less per day.)

The study found no link between calcium supplements and a lower risk of breast cancer.
