Increasing Dietary Fiber Intake Before Surgery in Adults with Colorectal Cancer Using Personalized Advice or Dried Vegetable Products

What this Trial Is About

Researchers are investigating how to increase dietary fiber intake before surgery in adults with colorectal cancer. This randomized controlled trial aims to explore whether personalized digital dietary advice or a dried vegetable product can help patients increase their fiber intake compared to continuing their habitual diet. The goal is to assess the feasibility of these methods before larger studies are conducted, focusing on improving outcomes after colorectal cancer surgery. Participants are randomly assigned to one of three groups one receiving personalized dietary advice through an online tool tailored to their eating habits, another consuming two daily sachets of dried chicory root cubes providing natural fiber, and a control group maintaining their usual diet. The intervention spans the period between diagnosis and surgery, typically around four weeks but varying depending on individual patient factors and scheduling. During the study, participants will provide dietary recalls at baseline, mid-intervention after two weeks, and at the end. Researchers will assess changes in fiber intake, stool patterns, gastrointestinal symptoms, quality of life, and fecal and plasma microbial metabolites. They will also monitor fecal microbiota composition and track length of hospital stay up to 90 days after surgery. This comprehensive evaluation aims to support future studies on dietary fibers role in surgical outcomes.
