Abstract | OBJECTIVE: DESIGN: Randomized crossover trial. SUBJECTS: Twenty-three normocalciuric patients with a history of calcium kidney stones (8 women and 15 men, mean age 50.7+/-14.6 years) with 24-hour urinary calcium < or =10.3 micromol, 24 hour urinary oxalate excretion between 228 and 963 micromol, and a urinary calcium increase of < or =1.0 micromol in 4 hours after a 25 micromol oral calcium load. SETTING: Four-day, free-living adaptation period, followed by 2-day metabolic unit study. INTERVENTION: The study compared consumption of 2 servings of beef (43 g protein for women and 50 g for men) daily with an equal amount of protein from plant foods including legumes, nuts, and grains.
