Abstract in brief

The study investigates how gut transit time affects the gut microbiome and evaluates the blue dye method as a cost-effective way to measure this transit time.
Findings indicate that gut microbiome composition can distinguish between different gut transit time classes, with longer transit times associated with specific microbial species.
The blue dye method is shown to be a more effective marker of gut microbiome function compared to traditional measures like stool consistency and frequency, making it suitable for large-scale health research.
