Dietary Macronutrient Intake and the Gut Microbiome in Adults Undergoing Bariatric Surgery for Obesity.

ABSTRACT: Limited information linking dietary intake to gut metagenomic data in bariatric surgery patients is available. We examined whether there were correlations between macronutrient intake and the gut microbiome and related gene pathways prior to and following bariatric surgery. Participants were 29 adults living with obesity undergoing bariatric surgery (93% females). Three-day food records were analyzed prior to and after surgery to estimate mean daily intakes of macronutrients to derive measures of diet quality [glycemic index, added sugar intake, and the Healthy Eating Index 2015 (HEI-2015)]. Pre- and post-operative stool samples were sequenced using whole-genome shotgun sequencing to identify changes in microbial composition. Diversity indices and differential abundance were calculated, an
