Walnut intake influences gut microbial gene expression
1. In this randomized controlled trial, a walnut-enriched diet was associated with a greater diversity of actively expressed genes in the gut microbiome than the other study diets. 2. A walnut-enriched diet also led to greater expression of metabolism-related genes and increased expression of the gene glycine amidinotransferase (GATM) in the gut microbiota. Evidence Rating
