Summary

This pilot study looked at how two different diets affect people with primary sclerosing cholangitis (PSC), a rare liver disease. Twenty adults were randomly assigned to either a vegan/low-sulfur diet or the specific carbohydrate diet for 8 weeks, with support from dietitians. The main goal was to see if the diets changed the diversity of bacteria in the gut, and researchers also tracked liver enzyme levels.

What this could lead to
If successful, this study could point toward a dietary approach that improves gut health and liver function in people with primary sclerosing cholangitis.
What could go wrong
This is a very small pilot study with only 20 participants, so results may not apply to everyone. It also relies on participants sticking to strict diets, which can be hard to maintain.
