Virginia Tech (USA) researchers found that calcium intake among US adolescents has remained constant, if inadequate, since the 1970s and does not appear to be linked to soft drink consumption. Milk consumption among adolescent girls is low, with this group falling far below recommended dietary levels of calcium consumption. So drink some milk!
Conclusion: carbonated soft drink consumption among adolescent girls is modest and does not appear to be linked to decreased calcium intake. The analyses in this paper show that creative effective, efficient, and targeted policies should be considered to help adolescent girls increase calcium intake. Making low-fat milk products, flavored milks, calcium-fortified beverages and foods more attractive and available will help encourage girls to consume more of this important mineral. When adequate calcium intake is not achieved through foods, health professionals should consider recommending calcium supplements.
