简要总结

This pilot study is being conducted to evaluate whether consumption of diet soda sweetened with sucralose and acesulfame-potassium leads to changes in the gut microbiota. Following a one week run-in period, healthy, young adults are randomized to consume either diet soda or carbonated water (control) three times per day for one week. Stool and urine samples are collected at baseline, following the run-in, and after the one-week intervention.
