Prevotella/Bacteroides Ratio

The Prevotella/Bacteroides Ratio is a calculated value that compares two bacterial groups involved in breaking down carbohydrates, fibre, and other dietary components. Prevotella is often linked to fibre and plant based carbohydrate fermentation, while Bacteroides is involved in breaking down a broader range of dietary material. This ratio may reflect patterns in diet, fermentation activity, and the overall composition of the gut microbiome. A low or high value does not point to one specific condition, but it can help show whether the balance between these two bacterial groups differs from the expected microbiome pattern.
