Objectives: The human gastrointestinal tract (GI)may play a critical role in the prevention of obesity and metabolic diseases. Considering the importance of a healthy diet for optimal health, this study examined associations of diet quality assessed by three a priori-defined dietary patterns (Healthy Eating Index 2010 [HEI-2010],Mediterranean Eating Pattern for Americans [MEPA], and Dietary Approaches to Stop Hypertension [DASH] with gut microbiota, short-chain fatty acids (SCFA) and intestinal permeabilitymarkers in adult obese participants.

Conclusions: Blautia abundance and inversely associated with intestinal permeability markers such as urinary 24-h sucralose levels suggesting diet quality may have positive impact on the human GI community.
