Summary

The purpose of this study is to identify calcium metabolism characteristics in Mexican American adolescents. The investigators predict that calcium requirements to maximize bone health in this population will be lower than for white youth but higher than their current intakes.

Conditions

Interventions

DIETARY_SUPPLEMENT

Low Calcium Diet

The basal diet will contain 600 mg of Ca per day and constant sufficient amounts of all other nutrients. Additional Ca will be given unfortified beverages served three times per day. Teens will be randomized to a lower (600-1200 mg/d)level of calcium in the first camp followed by the opposite (higher calcium diet)regime in the second camp.

DIETARY_SUPPLEMENT

High Calcium Diet

The basal diet will contain 600 mg of Ca per day and constant sufficient amounts of all other nutrients. Additional Ca will be given unfortified beverages served three times per day. Teens will be randomized to a higher (1100-2300mg/d)level of calcium in the first camp followed by the opposite (lower calcium diet)regime in the second camp.
