NCT ID NCT05371067

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study looked at whether difficulty digesting fructose (a sugar found in many foods) is linked to anxiety and changes in gut bacteria. Researchers compared 56 healthy young men who either absorb fructose normally or have trouble absorbing it. The goal was to see if fructose malabsorption affects mood and the gut microbiome, without any treatment being tested.
