Energy balance
Dietary composition (specifically fiber and carbohydrate content) is the primary driver of gut microbiota composition and functional metabolic output, overriding genetic background in shaping enterotypes.
Focus on long-term dietary patterns, specifically increasing fiber and complex carbohydrates, to support a diverse microbiota. While you may not change your 'enterotype' overnight, your gut microbes will rapidly adjust their functional output (gene expression) to process the food you eat. Prioritize plant-based fibers to encourage beneficial bacteria like Prevotella and Bacteroidetes.
enterotypes were found to be strongly associated with long-term diets, with protein and animal fat correlating with the enterotype characterized by high levels of Bacteroidetes, and carbohydrates with the Prevotella enterotype
Why this rating
Based on multiple metagenomic/transcriptomic studies comparing distinct populations (European vs. African, lean vs. obese).

- Breast milk oligosaccharides (HMOs) selectively promote the growth of specific beneficial bacteria (Bifidobacterium longum subsp. infantis) and shape the infant gut microbiota towards a state that supports immune development and digestion.Good
- Aging is associated with a decrease in gut microbiota diversity and a shift in the Firmicutes/Bacteroidetes ratio, which correlates with increased inflammation and reduced production of beneficial metabolites like butyrate.Good
