ISAPP’s scientific consensus definition of gut health - International Scientific Association for Probiotics and Prebiotics (ISAPP) Gut health is a commonly used term that previously had no scientific definition. In the paper, the group defines gut health as: “a state of normal gastrointestinal function without active gastrointest...

This podcast gives you in the inside scoop on ISAPP's recently published scientific consensus definition of gut health! Hear from the 2 lead authors about the 6 domains of gut health and what the definition means for future study design.

The Gut Health Benefits of Sauerkraut A new UC Davis study suggests that sauerkraut could help protect your gut, an essential part of overall health.

Keep calm and eat your (fermented) veggies! www.ucdavis.edu/food/news/gu...

The study found that sauerkraut, whether store-bought or prepared at a laboratory scale, exerts intestinal barrier protective effects, likely mediated by fermentation-derived metabolome – further research to study contribution of specific metabolites on intestinal barrier function is needed

The fermented cabbage metabolome and its protection against cytokine-induced intestinal barrier disruption of Caco-2 monolayers | Applied and Environmental Microbiology Fermented vegetables are increasingly associated with health benefits. However, the importance of microbial transformations to foods during the fermentation process remains to be determined. We found ...
