First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at how drinking beverages with different sweeteners—low-calorie sucralose, refined sugar, or natural fruit juice—affects blood sugar control and gut health in healthy adults. Over three weeks, 42 participants drank one type of sweetened drink daily. Researchers measured blood sugar and insulin responses, as well as changes in gut bacteria and inflammation markers. The goal was to understand real-world effects of common sweeteners on metabolism.
