Metabolic health risks of sorbitol consumption

Overview

Researchers at Washington University in St. Louis have identified metabolic pathways through which sorbitol, a common sugar alcohol used in sugar-free products, may impact health. Initial findings published in Science Signaling suggest that because sorbitol is chemically similar to fructose, the body can convert it into a fructose-related compound. Using zebrafish for experimentation, researchers noted that the intestine can also produce sorbitol from glucose following carbohydrate-heavy meals.

Subsequent details from the study clarify that under specific conditions, sorbitol can be converted in the liver into fructose-1-phosphate. This process activates metabolic pathways that promote the accumulation of fat and glycogen in the liver. The research highlights the critical role of the gut microbiome in mitigating these risks; specifically, bacteria of the genus Aeromonas typically break down sorbitol into harmless byproducts. In models where these bacteria were lacking, researchers observed the development of fatty liver within one week of sorbitol consumption.
