The Sweetener Study Finds an Association, Not a Verdict
Nearly 13,000 adults with higher intake showed faster cognitive decline, especially below age 60 and with diabetes.
Summary
Nearly 13,000 adults with higher intake showed faster cognitive decline, especially below age 60 and with diabetes.
An eight-year Brazilian cohort study tracked 12,772 adults and seven low- or no-calorie sweeteners. The highest-intake group experienced a faster decline on memory and thinking tests than the lowest-intake group, a difference the researchers compared with about 1.6 additional years of cognitive aging. Food questionnaires and observational data cannot establish that sweeteners caused the decline; health conditions, diet, and other unmeasured factors may contribute.
