New Study Links Artificial Sweeteners too Accelerated Brain Aging, Particularly in Midlife
Breaking News: A recent study published in the journal Neurology has revealed a potential link between the consumption of six common artificial sweeteners and accelerated brain aging, with individuals potentially experiencing cognitive decline equivalent to 1.6 years of aging. The findings raise concerns about the widespread use of “sugar-free” products.
The research,led by Associate Professor Claudia Kimie Suemoto at the University of São Paulo,Brazil,followed over 12,000 Brazilian civil servants between the ages of 35 and 75,with an average age of 52,as part of the 2008 “Electronic Study on Adult Health in brazil” (ELSA-Brasil). Participants were categorized based on daily sweetener intake: low (approximately 20 mg/day), medium (approximately 66 mg/day), and high (approximately 191 mg/day). Notably, a single can of sugar-free cola can contain around 200 mg of aspartame.The study demonstrated that even low levels of sweetener consumption were associated with observable declines in brain function. The effects were more pronounced in the medium and high intake groups. Researchers found that consuming just one can of sugar-free cola daily may contribute to brain aging of 1.6 years and a 62% reduction in cognitive ability.
The impact appears to be most important in individuals under the age of 60. The study also indicated a stronger affect on those with diabetes, though non-diabetic individuals are not immune. The negative effects on brain health were less pronounced in older participants.
While the exact mechanisms are still under investigation, experts suggest several potential pathways. Aspartame may break down into toxic byproducts that damage brain cells, impacting memory and thinking. Erythritol has been linked to cerebrovascular damage, potentially reducing blood flow and increasing stroke risk. Othre sweeteners may contribute to brain inflammation or blood clotting, accelerating cognitive degeneration.
Interestingly, one sweetener tested – tagatose – showed no association with declining brain health. Tagatose is naturally found in certain fruits and dairy products. Researchers suggest considering tagatose, or natural sweeteners like honey and maple syrup, as alternatives. However, tagatose is not currently approved for use in food products in Taiwan.”Even a small amount of artificial sweetener is associated with brain aging and cognitive decline,” warns farming expert Wayne, who highlighted the study on his Facebook page, “Wayne’s farming Life,” and blog. He urges consumers to reconsider their choices before reaching for “sugar-free” drinks or snacks, questioning whether the perceived benefit of sweetness outweighs the potential risks.The artificial sweeteners examined in the study included:
Aspartame
Saccharin
Potassium Acetylsulfonate (AK)
Erythritol
Xylitol
Sorbitol
