Relationship between carbonated and other low nutrient dense beverages and bone mineral content of adolescents

摘要

Low nutrient dense beverages such as carbonated drinks are increasing in the adolescent's diet, and concern has been raised that these beverages, particularly colas, reduce bone mass. We determined whether the type of low nutrient dense beverage as well as the amount was related to bone mineral content and accumulation during the two years spanning the time of peak bone mass accrual in adolescence. Total body bone mineral content (BMC) and dietary intakes were obtained for 59 boys and 53 girls when each subject was +/- one year of his or her measured age of peak rate of BMC. Consumption of low nutrient dense beverages was negatively related to BMC (r = -0.256, P = 0.03) and accrual (r = -0.227, P = 0.05) for adolescent girls but not boys. Milk beverage intake in both boys and girls was inversely related to low nutrient dense beverage consumption (r = -0.343, P 0.01; r = -0.244, P = 0.08, respectively). Low nutrient dense beverage ingestion by adolescents appeared to reduce bone mineral accrual and BMC in teenage girls by replacing milk beverages.
