3 artificial sweeteners could alter the gut microbiome, increasing the risk of obesity, diabetes and digestive problems
I artificial sweeteners cause "communication disruption" between gut bacteria, changing the microbiome and potentially increasing the risk of disease.
Intestinal bacteria positively affect the health of our body, but to do so they must be present in the right balance. This is partly maintained by a "communication" mechanism used by the bacteria themselves, called quorum sensing, which allows these microorganisms to detect and respond to cell population density by regulating their genes and influencing their behavior.
Artificial sweeteners, on the other hand, interrupt this communication, which indicates that they can be problematic if taken long-term.
A systematic review
The new study aimed to understand how sweeteners are able to influence intestinal health; for this research, light-emitting bacteria were used whose emission was reduced when bacterial communication was interrupted.
What did it turn out? The three most common sweeteners have all prevented bacterial communication - we're talking about saccharin, Aspartame e sucralose. Three other less common sweeteners, acesulfame potassium (Ace-K), advantame e neotame, however, they did not cause this effect.
What has been found is that the most popular artificial sweeteners interfere with the communication between bacteria that regulate important functions, and once this is damaged, the bacteria cannot behave properly as a 'community'. When you stop bacterial communication, you are disrupting the natural bacterial balance in the gut which can, in turn, cause digestion problems e increased risk of obesity and type two diabetes and not only.
In the face of this research, manufacturers of beverages and foods with artificial sweeteners should begin to better label their products to show how much sweetener they contain, so that consumers can make informed choices.
