Artificial Sweeteners May Speed Up Cognitive Aging, Large Brazilian Study Finds
A Brazilian study of nearly 13,000 adults over eight years found that higher intake of six common artificial sweeteners (aspartame, saccharin, acesulfame K, erythritol, xylitol, sorbitol) was linked to faster cognitive decline; tagatose showed no such effect. The highest consumers declined about 62% faster than the lowest, roughly equating to 1.6 extra years of aging, with stronger effects in adults under 60 and those with diabetes. The study is observational and relies on self-reported intake, so it shows associations, not causation.
