Summary

This study tests whether drinking beetroot juice for a week before colorectal surgery can help the gut start working again sooner. About 170 adults will be randomly assigned to drink either real beetroot juice or a placebo. Researchers will track when patients can eat solid food and pass gas or stool, and will also study blood and tissue samples to understand how beetroot juice affects inflammation.
