Researchers from Brazil have investigated the effects of six common : aspartame, saccharin, potassium acesulfame, erythritol, xylitol, and sorbitol.
The results were unexpectedly alarming, reports Daily Mail: regular consumption of these substances is linked to a faster decline in memory, speech, and cognitive abilities.
The reasons behind this are still being studied. However, preliminary data suggest that some sweeteners can break down into toxic compounds that harm brain cells or even trigger the formation of blood clots in blood vessels.
What Does “A Lot” Mean?
Interestingly, it takes only a small amount to see negative effects. Researchers note that individuals consuming between 190 to 200 milligrams of sweeteners daily (about the amount in one can of ) had brains that aged, on average, 1.6 years faster than those who consumed them less frequently.
Even those who used small amounts (less than one packet of sweetener per day) showed some decline in cognitive functions.
Who Is Most at Risk?
The study, which involved over 12,000 adults, lasted eight years. The strongest effects were observed in middle-aged individuals, particularly those suffering from .
In contrast, among older participants (60+), sweeteners did not have a significant impact on brain function. This may be explained by the fact that changes in older age occur independently of diet.
There Is a Safe Alternative
Researchers also examined tagatose—a natural sweetener found in fruits and dairy products. It turned out that tagatose is not associated with cognitive decline and could be a safer choice for those looking to reduce their intake.
Key Takeaways
Artificial sweeteners have long been considered a convenient way to manage weight and blood sugar levels. However, scientists now warn that even in small doses, they may accelerate brain aging.
Instead of opting for diet “zero-calorie” drinks, it’s better to choose more natural solutions—from fresh fruits to natural sweeteners. This will help not only the body but also the mind stay youthful longer.
