Today at the American Association for Cancer Research (AACR) Annual Meeting 2017, University of Colorado Cancer Center researchers at Colorado State University present results of a phase II clinical trial of 29 people exploring the effects of adding rice bran or navy beans to the diets of colorectal cancer survivors.

Exercise options tax implications The current trial confirms that people can eat enough bean- and rice bran-enhanced foods to promote gut health at levels shown to prevent colorectal cancer in animals. Exercise 6 classification of tissues Guidelines from the American Institute for Cancer Research recommend reducing the risk of cancer by eating more vegetables, fruits, whole grains and legumes, such as beans. Exercise and anxiety management Ryan has established from these studies that eating a half-cup of beans and 30 grams of rice bran per day is enough to see changes in small molecules that can confer protection against colorectal cancer.

“The simple message is, ‘Food is medicine,’ and we are looking at how to simplify that and make it apply to our everyday lives,” says study co-author Regina Brown, MD, assistant professor at the CU School of Medicine and oncologist for CUHealth.

Brown is long-time collaborator of CU Cancer Center investigator and CSU assistant professor, Elizabeth Ryan, PhD.

The two met about 10 years ago, when Ryan was a researcher in CSU professor Henry Thompson’s Cancer Prevention Lab, and Brown was practicing medicine in Fort Collins and caring for her mother, who had uterine cancer.

“It was kind of a novel partnership and had we not dug in our heels it could have died, but I told Elizabeth, ‘Your work is so interesting and so valuable. Exercise motivation We have to take this translational research from the benchtop to the clinic.’ I guarantee, nine out of 10 of my patients, the first thing they ask is about their diet,” Brown said.

The study’s lead author is Erica Borresen, Ryan’s research associate and study coordinator, who worked with colorectal cancer survivors to make sure they ate their beans and rice bran provided in meals and snacks, and that they filled out their food logs and gastrointestinal health questionnaires.

The next phase of Ryan’s research examines effects of the cooked navy bean powder and rice bran on the colon tissue of people who have already had colorectal cancer and are at high risk for recurrence.

“I really feel that there’s hope in this being a practical solution to improve gut health and specifically colorectal cancer prevention,” says Ryan.
