Milk Calcium Could Affect Breast Cancer, Weight
OSLO, Norway--Researchers at the University of Oslo determined that high rates of childhood and adult milk consumption (three or more glasses per day) reduced the incidence of breast cancer. Published in the Sept. 15 issue of International Journal of Cancer (93:888-93, 2001) (www3.interscience.wiley.com), the study presented an analysis of dairy consumption and breast cancer incidence among 48,844 premenopausal Norwegian women. During a mean follow-up time of 6.2 years, 317 cases of breast cancer were diagnosed. Researchers, led by Anette Hjartaker, found that adult milk consumption tended to be negatively related to breast cancer incidence, and women drinking more than three glasses per day were less likely to develop breast cancer as compared to women who did not.
In addition, the calcium found in dairy products may help children maintain a healthy body fat percentage during the critical years of body fat development, according to research presented at the American College of Nutrition's (www.am-coll-nutr.org) annual sympostum in Orlando and published in the International Journal of Obesity (25:559-566, 2001) (www.naturesj.com/sj/index.html). For eight years, researchers from the University of Utah followed 53 healthy children (ages two to eight) with low calcium intakes and randomly divided them into dairy or non-dairy groups. Both groups had similar caloric and fat intakes, and the dairy group was supplemented daily with four servings of milk and milk group foods (1,200 mg calcium). While the children in both groups had similar total body fat levels at baseline, the children in the dairy group ended the study with lower body fat levels.
