Sweeteners Linked to Cognitive Decline
8 Dec
Summary
- Certain sweeteners may harm brain health over time.
- Aspartame and saccharin linked to faster cognitive decline.
- FDA deems several artificial sweeteners safe for consumption.

Recent studies indicate that commonly used artificial sweeteners may have adverse effects on long-term brain health. Research published in Neurology found associations between sweeteners like aspartame, saccharin, and erythritol with declines in memory and overall cognitive function. These findings suggest that regular consumption of these sugar substitutes could negatively impact cognitive abilities over time.
Specifically, individuals who consumed aspartame and saccharin showed a 62% faster decline in cognitive functions, comparable to aging 1.6 years more rapidly. These results are concerning as these sweeteners are often marketed as healthier alternatives to sugar, particularly in low-calorie drinks. However, the study's senior author noted that higher consumption of sweeteners correlates with global cognitive decline.
Despite these emerging concerns, regulatory bodies like the Food and Drug Administration (FDA) maintain that sweeteners such as saccharin, sucralose, aspartame, xylitol, erythritol, stevia, and monk fruit are safe for ingestion. This creates a complex landscape for consumers navigating the purported health benefits versus potential risks associated with artificial sweeteners.
