Consuming Cola May Up Osteoporosis Risk For Older Women
Osteoporosis in Women and Cola
According to the National Osteoporosis Foundation, approximately 55 percent of Americans, mostly women, are at risk of developing osteoporosis, a disease of porous and brittle bones that causes higher susceptibility to bone fractures. Now, Katherine Tucker, PhD, director of the Epidemiology and Dietary Assessment Program at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University, and colleagues have reported findings in the American Journal of Clinical Nutrition that cola, a popular beverage for many Americans, may contribute to lower bone mineral density in older women, a condition which increases risk for osteoporosis.
Tucker, also a professor at the Friedman School of Nutrition Science and Policy at Tufts, and colleagues analyzed dietary questionnaires and bone mineral density measurements at the spine and three different hip sites of more than 2,500 people in the Framingham Osteoporosis Study whose average age was just below 60. In women, cola consumption was associated with lower bone mineral density at all three hip sites, regardless of factors such as age, menopausal status, total calcium and vitamin D intake, or use of cigarettes or alcohol.
However, cola consumption was not associated with lower bone mineral density for men at the hip sites, or the spine for either men or women. The results were similar for diet cola and, although weaker, for decaffeinated cola as well.
