Carbonated Beverages and Bone Health
sodaThe result from this study of adolescent girls confirm our earlier findings of an association between bone fractures and carbonated beverage consumption in older women former college athletes. They also support our hypothesis that the association is due to the cola drinks, which contain phosphoric acid.

“Purpose: The aim of this study was to explore the association between carbonated beverage consumption, as well as other nutritional intake, and the occurrence of bone fractures in girls (mean +/- SD) 14.3 yr +/- 1.8 and boys 14.6 yr +/- 1.6. Methods: Food-frequency questionnaires and medical histories were obtained from 76 girls and 51 boys. Subjects were recruited from a swimming club and physicians' offices; their physical characteristics are representative of the normal adolescent population. Results: The data show a strong association between cola beverage consumption and bone fractures in girls [the adjusted odds ratio (OR) = 3.59; 95% confidence interval (CI) 1.21, 10.75; p = 0.022]. High intake of dietary calcium was protective (adjusted OR = 0.284; 95% CI 0.087, 0.920; p = 0.036). No association between the non-cola drinks and bone fractures was found. In boys, only total caloric intake was associated with the risk of bone fractures; the association was inverse. Conclusion: The high consumption of carbonated beverages and the declining consumption of milk are of great public health significance for girls and women because of their proneness to osteoporosis in later life.”

“Calcium intake and the calcium/phosphorus ratio in relation to bone fractures and osteoporosis are of great current interest. In earlier work, we reported a statistically significant association between the consumption of non-alcoholic carbonated beverages and bone fractures, which occurred among women form college athletes, 21-80 years of age. If was hypothesized that the association was attributable to cola drinks that contain phosphoric acid.”

“A higher activity level was inversely associated with risk of fractures (OR is 0.216; 95% CI 0.081, 0.573; p = 0.002). (Using a three-point scale of physical activity, a dose-response inverse relationship between activity and fractures was observed.”
