Medically Tailored Meals to Reduce Ultra-processed Food Intake in Colorectal Cancer Survivors

Официальное название

A Pilot Medically Tailored Meal-Based Intervention to Reduce Ultra-processed Food Intake Among Patients With Stages I-III Colorectal Cancer

Обзор

This research study is a three-arm, parallel-group randomized clinical trial that examines the feasibility and initial impact of consuming medically tailored meals to reduce intake of ultra-processed food and improve health and survival outcomes among 60 patients with stage I-III colorectal cancer.

Подробное описание

This research study is exploring whether medically tailored meals can help survivors with stage I-III colorectal cancer reduce their intake of ultra-processed foods and improve their health. Ultra-processed foods, such as packaged snacks, fast food, and sugary drinks, make up a large portion of many Americans' diets and have been linked to a higher risk of colorectal cancer and poorer survival. While experts recommend limiting these foods, many patients face challenges like limited time, cooking skills, or access to healthy options, making dietary changes difficult.

Medically tailored meals, designed by dietitians to meet specific health needs, may offer a practical solution by making healthy eating easier and more accessible. This study will evaluate whether these meals, with or without fresh produce, can improve diet quality, support healthier gut bacteria, and reduce inflammation. Researchers will measure changes in gut health and blood markers before and after the program to better understand how diet can influence recovery and long-term outcomes for colorectal cancer survivors.

This research study will last about 3 years. It includes a 2-week preparation period, a 6-week intervention with a medically tailored meals (MTM) program, 2 clinic visits (one prior to starting and one following the 6-week intervention period), 2 nutrition counseling visits with a registered dietitian (also conducted before and after the intervention), and follow-up contacts (4 weeks after the final visit and then every year for 3 years).

Because it is unknown which meal plan is best, participants will be randomized to one of these 3 meal plan groups:

* MTM: participants will receive 3 fully prepared, home-delivered, medically tailored meals per day for 6 weeks. * MTM plus Fresh Produce: participants will receive 2 fully prepared, home-delivered, medically tailored meals per day, plus weekly deliveries of fresh produce and accompanying recipes, for 6 weeks. * Control group: participants will receive weekly recipes and meal-planning materials only; no food will be provided.

Критерии исключения

• Participants who are receiving any other investigational agents or lifestyle/dietary interventions.
• Concurrent use of other anti-cancer therapy, including chemotherapy agents, targeted agents, biological agents, immunotherapy, or investigational agents not otherwise specified in this protocol.
• Any prior diagnosis of invasive (i.e., excluding intramucosal cancer) gastrointestinal cancer (including esophageal, small intestine, colon, pancreatic), or any diagnosis of other cancers (except non-melanoma skin) in which there has been any active treatment within the last three years.
