Study of the Effect of a Calcium-rich Diet on Bone Health in Girls (Calkids)

March 24, 2016 updated by: Joan Lappe, Creighton University

Effect of Calcium Foods on Bone Quality in Pubertal Females

The aim of this experimental study was to test the effect of increasing dietary calcium intake to 1500 mg/day on increases in bone quality in adolescent females. The hypothesis to be tested is: adolescent females who consume a high calcium diet will have a greater increase in bone quality, as measured by densitometry and ultrasound, than adolescent females who consume their usual dietary calcium intake.
