Mechanisms of dietary protein-induced changes in calcium absorption efficiency

What is the purpose of this trial?

To determine which functional group of amino acids is most responsible for the effects of dietary protein on intestinal calcium absorption. This study seeks to recapitulate the effect of increasing dietary protein on calcium absorption by adding selected amino acids to a low protein diet such that their total dietary content is equal to that of our high-normal protein diet.  We will determine which group of amino acids most improves calcium absorption.

If subjects participate in all three experimental diets they will be paid $750 plus an additional bonus ($150) for completeing the entire study, totaling $900 for their time and effort.
