Micronutrients & recovery
Long-term consumption of a diet rich in plant-based foods (high fiber, low meat) increases gut microbiota diversity and shifts the dominant bacterial genera from Bacteroides to Prevotella, which is associated with higher levels of short-chain fatty acid (SCFA) production and improved metabolic health.
To improve your gut health and metabolic function, prioritize a long-term diet rich in diverse plant-based foods (fruits, vegetables, resistant starches) and reduce meat consumption. This shifts your gut bacteria to produce more beneficial short-chain fatty acids, which support colon health, reduce inflammation, and improve insulin sensitivity. You do not need to eliminate all animal products, but increasing plant diversity is the most effective lever for microbiota health.
In adults, diets that have a high proportion of fruit and vegetables and a low consumption of meat are associated with a highly diverse microbiota and are defined by a greater abundance of Prevotella compared to Bacteroides, while the reverse is associated with a diet that contains a low proportion of plant-based foods.
Why this rating
Based on multiple observational studies (ELDERMET, Burkina Faso, Italian children, American adults) and mouse models showing consistent associations, though causality in humans is often inferred from cross-sectional data.

- A Low FODMAP diet effectively alleviates symptoms of Irritable Bowel Syndrome (IBS) in approximately 85% of cases by reducing the fermentation of rapidly absorbable carbohydrates in the small intestine, thereby reducing gas production and visceral hypersensitivity.Good
- Obesity and insulin resistance are associated with a gut microbiota profile characterized by a lower proportion of Bacteroidetes and a higher proportion of Firmicutes/Actinobacteria, which may contribute to increased energy harvest and inflammation via lipopolysaccharide (LPS) translocation.Moderate
