Cola may weaken bones

Cola may contribute to lower bone mineral density in older women, which may in turn increase the risk of osteoporosis, experts report.

Cola may contribute to lower bone mineral density in older women, which may in turn increase the risk of osteoporosis. This is according to a report by dr Katherine Tucker, director of the Epidemiology and Dietary Assessment Program at the Jean Mayer USDA Human Nutrition Research Centre on Aging at Tufts University, and colleagues in the American Journal of Clinical Nutrition.

How the study was conducted
The researchers analysed 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.

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.

Other fizzy drinks seem safe
"However, we did not see an association with bone mineral density loss for women who drank carbonated beverages that were not cola," she said.

Results still preliminary
Tucker stresses that as with any epidemiological study, the results should be viewed with caution.
