Study Links Artificial Sweeteners to Cognitive Decline

A study published in the medical journal Neurology, by the American Academy of Neurology, reveals that individuals consuming high amounts of artificial sweeteners may face a significantly faster cognitive decline. The research followed 12,772 adults in Brazil over approximately eight years, assessing their intake of seven common sweeteners: aspartame, saccharin, acesulfame K, erythritol, xylitol, sorbitol, and tagatose.

The findings indicate that six of these sweeteners were associated with a 62% faster decline in overall cognitive function compared to those with the lowest intake, equating to about 1.6 additional years of brain aging. Moderate consumers also showed a 35% faster decline.

The association was particularly pronounced in adults under 60 and those with diabetes. While the study does not establish causation, it raises concerns about the long-term effects of sugar substitutes, which are marketed as healthier alternatives.

The researchers call for further studies to clarify whether artificial sweeteners contribute to cognitive decline or if other factors are involved.
