Official title

Long-term Impact of Protein on Calcium Kinetics

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Osteoporosis is a major health problem in men and women in this country and the incidence of this disease is rising. We think that environmental factors such as nutrition may play a role in the increasing prevalence of osteoporosis. In particular, we think that a diet that is too low in protein may be contributing to bone loss. The primary purpose of this study is to compare the long-term impact of a low protein diet on measures of bone and calcium metabolism.
