The Claim

In adults aged 60 and older, consumption of low- and no-calorie sweeteners is not significantly associated with cognitive decline over an 8-year period, and age modifies the relationship between sweetener intake and cognitive outcomes.

In plain English

Among adults aged 60 and older, drinking beverages with low- or no-calorie sweeteners does not show a measurable link to memory or thinking decline over eight years, and age influences how sweetener use relates to cognitive changes.

See the scientific wording

In adults aged 60 and older, no significant association was found between consumption of low- and no-calorie sweeteners and cognitive decline over an 8-year period, suggesting age may modify the relationship between sweetener intake and cognitive outcomes.

Why this might work

As people age, their brain becomes better at maintaining stable energy use and blood flow, even when they consume sweeteners that might otherwise disrupt these processes in younger people. This stability prevents the brain from showing signs of decline over time.

    For people 60 and older, eating or drinking things with artificial sweeteners didn’t make their memory or thinking skills get worse over 8 years, according to this study. But for younger people, it might.
