Vinegar beverage intervention study in constipation-prone adults
This BioProject represents a randomized, double-blind, placebo-controlled trial designed to investigate the effects of vinegar beverage or placebo beverage consumption on defecation status in constipation-prone adults. Stool samples were collected before and after the intervention and analyzed using 16S rRNA gene sequencing to characterize changes in gut microbiota composition. The study aims to clarify the relationship between dietary vinegar intake, bowel function, and intestinal microbial profiles, thereby contributing to a better understanding of dietary strategies for improving gastrointestinal health.
