Do artificial sweeteners cause inheritable biological changes?
A recent study from the University of Chile indicates that common artificial sweeteners, specifically sucralose and stevia, may induce inheritable biological alterations. Researchers observed that these non-nutritive sweeteners could impact gut microbiota, gene expression, and metabolism in mice.

A recent study from the University of Chile indicates that common artificial sweeteners, specifically sucralose and stevia, may induce inheritable biological alterations. Researchers observed that these non-nutritive sweeteners could impact gut microbiota, gene expression, and metabolism in mice. Notably, some of these effects were found to persist in the first and second generations of offspring, even in individuals not directly exposed to the sweeteners. This suggests a potential for transgenerational transmission of changes triggered by artificial sweetener consumption.
