It’s official – artificial sweeteners cause metabolic disturbance!
A new study in Nature finds that artificial sweeteners such as saccharin, sucralose and aspartame can actually raise blood sugar levels instead of reducing them, inducing glucose intolerance.
This completely opposes the regularly reinforced opinion that artificial sweeteners pose no risk to consumers.
The study demonstrates that the consumption of commonly used artificial sweeteners drives glucose intolerance through creating alterations in the gut microbiota. These changed microbial metabolic pathways in turn create susceptibility to metabolic disease e.g. obesity, fatty liver, type 2 diabetes etc.
Whilst the study was carried out on mice, the researchers show similar artificial sweetener-induced dysbiosis and glucose intolerance in healthy subjects. Although the direct mechanism for creating the dysbiosis is still unknown, the paper calls for an urgent reassessment of the massive and widespread usage of artificial sweeteners.
