Popular diet soda ingredient tied to gut bacteria changes passed down across generations: study
- A Chilean study shows multigenerational changes in metabolism-related genes after exposure to sucralose or stevia in mice.
- The study also observed lasting changes in gut bacteria and reduced short-chain fatty acids across generations.
- Sucralose showed a stronger and more lasting effect than stevia in the mouse model.
- Researchers caution the findings do not prove the same effects occur in humans but advocate more research.
- Experts say the absence of direct human data means cautious interpretation and moderation.
- The International Sweeteners Association defended safety and noted limited relevance of animal studies to humans.
- Around 140 million Americans reportedly use non-nutritive sweeteners regularly.
- The researchers call for moderation and more long-term research into sweeteners' effects.
- The study involved 47 mice divided into three groups and observed across two generations.
- Stevia's impact was smaller and faded sooner compared to sucralose in the study.
