Effect of fiber-modified kombucha tea on gut microbiota in healthy population: A randomized controlled trial (RCT)

Summary

Researchers studied a kombucha tea drink enriched with fiber from chicory root in healthy adults over six weeks. The study found that people who consumed the fiber-enriched kombucha had lower triglyceride levels (blood fats) and beneficial changes in their gut bacteria, particularly an increase in Bifidobacterium, a bacteria known to support digestive health. These results suggest that this type of kombucha could be beneficial for metabolic and gut health, though more research is needed to confirm these benefits.

Background

The development of functional foods with health-promoting properties is important for addressing chronic diseases. Kombucha tea is a fermented beverage that has gained popularity for its perceived health benefits, but clinical evidence on its impact on human gut microbiota remains limited. This study evaluates the effects of fiber-enriched kombucha on biochemical parameters and gut microbiota composition in healthy individuals.

Objective

To evaluate the effects of fiber-enriched kombucha tea on biochemical parameters and gut microbiota composition in a healthy population through a randomized controlled trial.

Results

Fiber-enriched kombucha consumption led to significant reduction in triglyceride levels compared to control group, increased Bifidobacterium abundance, and decreased Ruminococcus torques. Significant shifts in beta diversity were observed between groups at the final time point, indicating meaningful alterations in gut microbiota composition.

Conclusion

The fiber-enriched kombucha drink demonstrated potential health benefits including triglyceride modulation and positive alterations in gut microbiota composition. These findings suggest its promise as a functional beverage for improving metabolic and gut health in healthy individuals, though further studies are warranted.
