Artificial sweeteners linked to cognitive decline in large study
Higher intake of artificial sweeteners linked to faster cognitive decline over 8 years, especially in diabetics.
Why it matters
- Artificial sweeteners are widely used as sugar substitutes.
- Cognitive decline is a major public health concern.
- Findings could impact dietary recommendations.
By the numbers
- 12,000+ participants followed for 8 years.
- 62% faster cognitive decline in high consumers.
- Highest intake group averaged 191 mg/day, equivalent to one can of diet soda.
The big picture
- Artificial sweeteners may not be as safe as previously thought.
- Stronger effects seen in diabetics suggest a potential vulnerability.
- Study highlights the need for more research on long-term effects of sweeteners.
What they're saying
- Skepticism about causation due to observational nature of the study.
- Questions about linking chemically different substances to the same outcome.
- Concerns about self-reported dietary data and potential confounding factors.
Caveats
- Observational study cannot prove causation.
- Self-reported dietary data may not reflect long-term habits.
- Underlying health conditions could contribute to cognitive decline.
What’s next
- More research with repeated dietary assessments and biomarkers.
- Studies on different types of sweeteners and specific populations.
- Potential changes in dietary guidelines based on further findings.
