New Health Risks of Artificial Sweeteners Identified by Study
Summary
A new study reviewed evidence on artificial and low-calorie sweeteners and found they may affect metabolism and gut bacteria. The research showed these sweeteners could raise markers linked to blood sugar control and potentially change gut microbes, though long-term health effects are still uncertain.Key Facts
- The study analyzed 21 clinical trials and large observational studies on non-nutritive sweeteners.
- Sweeteners were compared with noncaloric controls like water or placebo to focus on their direct effects.
- Consumption was linked to higher fasting insulin and higher HbA1c, a long-term blood sugar measure.
- Results suggest artificial sweeteners might not be metabolically inactive as previously thought.
- Types of sweeteners studied mainly included synthetic ones like aspartame, saccharin, and acesulfame potassium.
- Artificial sweeteners may change the composition and function of gut bacteria, based on microbiome testing.
- Experts say reducing sugar intake remains important despite potential sweetener effects.
- More research is needed to understand how different sweeteners impact health over time and in typical amounts consumed.
