Link Found Between Low-Calorie Sweeteners and Cognitive Decline

Recent research indicates a possible connection between the consumption of low- and no-calorie sweeteners (LNCSs) and accelerated cognitive decline. This study, published in the journal Neurology, highlights significant findings from a longitudinal observational investigation conducted by researchers from the Universidade de São Paulo in Brazil.

The study involved a cohort of civil servants aged 35 and older, utilizing data from the Brazilian Longitudinal Study of Adult Health. Researchers assessed participants' intake of various LNCSs using a Food Frequency Questionnaire. The average consumption of LNCSs among the 12,772 participants was recorded at 92.1 ± 90.1 mg/day.

Over an eight-year follow-up period, those in the highest consumption tertiles of LNCSs exhibited a more rapid decline in verbal fluency and overall cognitive abilities, particularly among individuals aged under 60. Conversely, no significant correlation was observed between LNCS consumption and cognitive decline in participants aged 60 and older.

Specific sweeteners, including aspartame, saccharin, acesulfame K, erythritol, sorbitol, and xylitol, were identified as having a particularly detrimental effect on cognitive functions, notably in memory and verbal fluency.

One of the co-authors of the study noted that while low- and no-calorie sweeteners are often perceived as healthier alternatives to sugar, their long-term effects on brain health may be concerning. This research raises important questions about the safety of these sweeteners and their implications for cognitive health.

As the consumption of LNCSs continues to rise globally, further research is necessary to fully understand their effects on brain health and cognitive functioning. This study emphasizes the need for consumers to be aware of the potential risks associated with these widely used sugar substitutes.
