Indication: Bone mass in young girls
Source: Am J Clin Nutr, November 2005;82(5):1115-26.
Research: The purpose of this study was to learn how to maximize young girls' peak bone mass during the rapid growth period of puberty, during which 60% of adult bone mass is accumulated. This placebo-controlled intervention trial randomly assigned 195 healthy girls at Tanner stage I-II, aged 10-12 years, with dietary calcium intakes of less than 900 mg per day to one of four groups: calcium (1000 mg) and vitamin D3 (200 IU); calcium (1000 mg); cheese (1000 mg calcium) and placebo. Researchers measured the effects of calcium supplementation on bone mass and body composition, and analyzed the data using traditional statistics as well as a new model that takes into account the rate of body growth.
Results: According to investigators, using cheese containing 1000 mg of calcium was most effective for the young girls because it appeared to be more beneficial for cortical bone mass accrual than the consumption of tablets containing a similar amount of calcium. The lead investigator in the study pointed out, however, that although the cheese containing 1000 mg of calcium seemed to have a greater effect, once researchers examined growth speed there was no beneficial effect observed for any of the interventions. Researchers pointed out that once you exceed certain levels of dietary calcium intake, it doesn't matter how much you take.
