The Claim
Reduction in fecal lithocholic acid following walnut consumption is positively associated with the relative abundance of Dorea and negatively associated with the relative abundance of Roseburia, indicating a microbial association between walnut intake, bile acid metabolism, and gut inflammation.
What the research says
Not yet evaluated
We are still looking at what the research says.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Eating walnuts is linked to lower levels of a bile acid called lithocholic acid in feces, and this change correlates with higher levels of Dorea bacteria and lower levels of Roseburia bacteria in the gut.
See the scientific wording
The reduction in fecal lithocholic acid after walnut consumption is positively associated with the relative abundance of Dorea and negatively associated with Roseburia, suggesting a microbial link between walnut intake, bile acid metabolism, and gut inflammation.
Walnuts feed gut bacteria that break down fiber and fats, which shifts the bacterial population to favor species that do not convert bile acids into harmful forms. This reduces the production of lithocholic acid, a compound that irritates the colon.
What the research says
1 studyThe study performed bivariate correlations between bacterial abundances and bile acid levels after walnut intervention. The statistically significant positive correlation with Dorea and near-significant negative correlation with Roseburia provide evidence of a microbial-bile acid relationship specific to walnut consumption.
