Several widely used sugar substitutes may be associated with faster declines in memory and thinking skills over time, according to research published in Neurology, the medical journal of the American Academy of Neurology.
The study followed nearly 13,000 adults and examined seven sweeteners that contain little or no calories. People who consumed the largest total amounts showed a more rapid decline in cognitive abilities than those who consumed the smallest amounts. The association was especially strong among people with diabetes.
The results do not show that sweeteners directly cause cognitive decline. They reveal an association, meaning other factors could help explain the pattern.
Seven Common Sweeteners Examined
Researchers studied aspartame, saccharin, acesulfame K, erythritol, xylitol, sorbitol and tagatose.
These ingredients are frequently added to ultra processed products, including flavored water, soft drinks, energy drinks, yogurt and desserts marketed as low in calories. Several are also sold separately for use in coffee, tea, cooking or baking.
Key Findings
The study followed 12,772 adults with an average age of 52.
Researchers examined seven sweeteners commonly found in flavored water, soda, energy drinks, yogurt, low calorie desserts and other ultra processed foods.
Participants who consumed the largest total amounts experienced faster declines in overall thinking and memory skills than those who consumed the smallest amounts.
The difference was comparable to approximately 1.6 additional years of aging.
The association appeared in adults younger than 60 but was not detected in those older than 60.
The findings show a link, but they do not prove that sugar substitutes cause cognitive decline.
