Do artificial sweeteners accelerate brain aging? Equivalent to a 1.6-year age gap; study of more than 10,000 people, published in a medical journal in 2025: A slightly older Innovative Tech

A 8-year study of 12,772 Brazilian adults found that higher intake of low- and zero-calorie artificial sweeteners was linked to faster cognitive decline.

People in the highest intake group declined 62% faster in memory and thinking than those in the lowest group, roughly equal to 1.6 years of aging.

The findings, published in Neurology and led by researchers at the University of São Paulo, raise concerns about the brain-health effects of sweeteners such as aspartame and xylitol.

The result suggests people may want to consider long-term diet choices more carefully, especially in relation to aging and diabetes.
