Mechanisms of dietary protein-induced changes in calcium absorption efficiency


Bone Resorption

What is the purpose of this trial?

The purpose of this study is to determine whether adding selected amino acids to a low protein diet improves intestinal calcium absorption to the same extent as if we increased your total protein intake from low to high normal. We will test 2 groups of amino acids and compare their effect to the known effect a high protein diet has on calcium absorption. 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 completing the entire study, totaling $900 for their time and effort.
