The Beans to Enrich the Gut Microbiome vs. Obesity's Negative Effects (BE GONE) Trial

You are being asked to take part in this study because either you are a survivor who has a previous history of colorectal cancer or an MD Anderson patient who had a precancerous colorectal polyp or you have a previous history of colorectal cancer, and you have a current adult body mass index (BMI) score of 25 or higher. The BMI score is used as an indicator of the level of body fat, based on height and weight. The goal of this clinical research study is to learn if eating canned, pre-cooked beans can help improve the levels of healthy bacteria in the digestive system and reduce the effects of obesity on cancer risk. This is an investigational study. Up to 80 participants will be enrolled in this study. All will take part at MD Anderson.
