The purpose of this study was to examine the association between meat and non-meat sources (including nuts) of protein and fat and gut microbiome changes.

Key Findings

Key Findings: Results showed that saturated fat had a greater effect on the microbiome than protein source. Once fats were accounted for in the statistical model, protein source significantly affected the diversity of the microbiome. Comment: more research in this area is needed to better understand the role that peanuts and other nuts play in diversifying the gut microbiome.
