Dietary Impact on Intestinal Sulfate Metabolism

This is a 5-week crossover pilot study of 15 highly motivated healthy volunteers who will consume two 7-day intervention diets: 1) a diet low in sulfur-containing amino acids (Low-S diet), emphasizing plant-based foods and fat sources; and 2) a diet high in sulfur-containing amino acids (High-S diet), emphasizing animal protein and fat sources. A 14-day washout period will follow each intervention, in which participants will eat their typical diets.
