Mixed
Microbiome responses to dietary interventions are highly personalized, meaning the same diet can produce different microbial and metabolic outcomes in different individuals based on their baseline microbiome composition.
Standard dietary advice may not work for everyone because your gut bacteria are unique. If a specific diet (like high fiber) doesn't improve your health markers, it might be due to your baseline microbiome. Future personalized nutrition may involve testing your microbiome to predict which foods will work for you.

A growing body of literature suggests that microbial responses to foods are personalized... The abundance of Prevotella, in particular, has been described as a way to differentiate between responders and non-responders with improved glucose metabolism following consumption of bread high in barley fiber.
Why this rating
Cites multiple studies (refs 16-21) showing responder/non-responder phenotypes, though the paper is a review.
