Artificial sweeteners age the brain by more than 1.6 years, study says

People who consumed high levels of artificial sweeteners, equivalent to one soda a day, experienced a significant decline in memory and word recall, compared to people who consumed less, a new study says.

"People who consumed low- or no-calorie sweeteners showed a 62% faster global cognitive decline than those who consumed smaller amounts, which is equivalent to 1.6 years of brain aging," said study author Claudia Kimie Suemoto.

The highest-consumer groups consumed an average of 191 milligrams per day, or one teaspoon of artificial sweetener. The middle-income group consumed an average of 66 milligrams, and the lowest-income group consumed 20 milligrams.

“Participants in the middle level showed a global cognitive decline of 35% or 1.3 years than those who consumed the lowest amount. The study is observational and I can’t say that artificial sweeteners cause cognitive decline. But we know that sweeteners are associated with worse cognitive trajectories.”

Non-nutritive sweeteners are used in processed foods and special products for diabetic patients.

The International Sweeteners Association, which represents the industry, told CNN that sweeteners are a safe and effective way to reduce sugar and calorie intake, a key public health goal to control obesity and type 2 diabetes.

Scientists studied several artificial sweeteners: aspartame, saccharin, acesulfame-K, erythritol, xylitol, sorbitol, and tagatose.

Of these, not all are problematic. Tagatose is also found in natural form, saccharin, acesulfame-K, and aspartame are FDA-approved.

Erythritol, xylitol, and sorbitol are sugar alcohols found in small amounts in cauliflower, eggplant, lettuce, mushrooms, spinach, plums, raspberries, and strawberries.

Manufacturers usually create and use them in carbonated drinks, tea, chewing gum, candies, chocolates, baked goods, ice cream, etc.

Studies have shown that erythritol and xylitol can cause blood platelets to clump together, creating clumps that can break off and travel to the heart, causing a heart attack or even to the brain, damaging blood vessels or causing a thrombosis.
