This study aimed to determine the feasibility of a whole food, plant-based (WFPB) dietary intervention in low-risk patients with chronic lymphocytic leukemia (CLL). Secondary outcomes explored whether adherence to a WFPB diet was associated with changes in CLL biomarkers and anthropometric measures of cardiometabolic health. The intervention included 8 live cooking classes, and multiple individual sessions with both a dietitian and health coach. Study findings and publications may be found under the Outcomes section of this website.
