Popis: Purpose: Epidemiological studies have reported that high calcium diet protects against kidney stone formation in normal subjects. This metabolic study was designed to elucidate the physiological and physicochemical effects conferring this apparent protection.Materials and Methods: A total of 21 normal volunteers underwent 2 phases of study in a crossover, randomized design, wherein they consumed constant metabolic diets that matched the estimated highest and lowest quintiles of calcium intake from published epidemiological studies.Results: Urinary calcium was significantly greater on the high calcium diet (148 ± 55 versus 118 ± 43 mg. daily, p
