Human and Bacterial Molecular Pathways in Cancer Risk:  Modulation by diet
Data is from a completed randomized cross-over feeding study, Carbohydrate and Related Biomarkers (CARB) , where 80 participants consumed two controlled diets for 28 days each. One diet was high in whole grains, fresh fruits and vegetables. The other substituted refined grains for whole grains, and provided carbohydrates from mostly high-glycemic index food sources. All food was provided to participants and energy content and macronutrient composition was identical in both diets. Each participant served as their own control. Participants collected stool at the beginning and end of each diet.
