# Artificial sweeteners linked to accelerated brain aging Research suggests common sweeteners may increase cognitive decline. - **Source:** [Latest Science News -- ScienceDaily](https://brifing.si/source/0eef8637-6c5b-4e79-8f5b-6c9c6b36cf16) - **Published:** 2026-07-18 - **Original article:** - **On Brifing:** https://brifing.si/s/aa8191ef-d6da-4a08-9f30-3853f2f446f0 ## Impact of artificial sweeteners A study indicates that widely used artificial sweeteners may accelerate cognitive decline. This effect is particularly pronounced in individuals with diabetes. ## Scope of the research The study tracked the sweetener consumption of 12,772 adults in Brazil over eight years. Those in the highest consumption group experienced faster cognitive decline. ## Which sweeteners were examined? The research examined seven common sweeteners, including aspartame, saccharin, acesulfame K, erythritol, xylitol, sorbitol, and tagatose. Six of these were linked to cognitive decline. ## Cognitive tests Participants underwent cognitive tests at the beginning, middle, and end of the study. These tests measured skills such as verbal fluency, working memory, and processing speed. ## Age factor The study found a stronger association between sweetener consumption and cognitive decline in participants under 60. This link was not observed in those over 60. ## Importance of the findings This study highlights the potential effects of artificial sweeteners on cognitive health. However, the results do not establish a definitive causal relationship, and further research is needed. ## Sources covering this story - https://www.sciencedaily.com/releases/2026/07/260717033213.htm — --- _Summary written by Brifing from the original reporting.
