These six common artificial sweeteners are now linked to cognitive decline

 For decades, artificial sweeteners have been marketed as a guilt-free alternative to sugar—helping people manage weight, control blood sugar, and avoid cavities without sacrificing sweetness. But mounting research suggests these chemical substitutes may come with a hidden cost: accelerated brain aging and cognitive decline. A new study published in Neurology has linked six widely used artificial sweeteners—aspartame, saccharin, acesulfame potassium, erythritol, xylitol, and sorbitol—to troubling declines in memory, language, and thinking skills.

The findings add to a growing body of evidence that these sugar substitutes, found in everything from diet sodas to sugar-free candies, may be silently harming brain health. While scientists are still unraveling the exact mechanisms, previous research suggests these sweeteners contribute to inflammation, blood clotting, and even toxic breakdown products that damage delicate neural pathways. The implications are alarming—especially since many people consume these substances daily, often without realizing it.

Six artificial sweeteners—aspartame, saccharin, acesulfame potassium, erythritol, xylitol, and sorbitol—are linked to faster brain aging and cognitive decline.
Even small daily amounts (equivalent to one can of Diet Coke) accelerated brain aging by 1.6 years.

The effect was strongest in middle-aged adults under 60, suggesting early dietary habits may set the stage for later cognitive problems.

Erythritol has also been tied to blood vessel damage in the brain, increasing stroke risk.

Only tagatose, a natural sweetener found in some fruits and dairy, showed no negative effects....<<<Read More>>>...
