The Claim
The degree of food processing in dietary patterns is associated with gut microbiome diversity and composition in adults, with unprocessed foods correlating with higher microbial richness (r = 0.26) and Shannon diversity (r = 0.24).
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Diets with more unprocessed foods are linked to greater diversity and richness of gut bacteria in adults.
See the scientific wording
Dietary patterns, particularly the degree of food processing, are strongly associated with gut microbiome diversity and composition in 10,068 adults, with unprocessed foods correlating with higher microbial richness (r = 0.26) and Shannon diversity (r = 0.24), suggesting diet is a major environmental driver of microbial ecosystem structure.
Eating whole, unprocessed foods delivers fibers and complex plant compounds into the gut, which gut bacteria break down for energy. This feeding process allows more types of bacteria to survive and multiply, increasing the overall number and variety of microbes in the colon.
What the research says
1 studyThis big study found that what people eat strongly affects the types and numbers of good bacteria in their gut — eating more whole, unprocessed foods is linked to a healthier, more diverse gut microbiome.
