Food for Thought - A Nutrition Intervention for Women Undergoing Active Treatment for Triple Negative Breast Cancer

PRIMARY OBJECTIVES: I. Evaluate the efficacy of a remotely delivered, highly accessible, 3-month MIND diet intervention (MIND-Breast Cancer \[BC\]) versus (vs.) general health curriculum (GHC) control to reduce CRCI and associated neuropsychological symptoms in 60 racially and ethnically diverse women with clinical stage II-III TNBC. II. Evaluate the sustainability of dietary changes and outcome measures 6-months post-intervention. EXPLORATORY OBJECTIVE: I. Explore underlying mechanisms of the MIND-BC diet on CRCI and effects of early versus later participation in the dietary intervention. OUTLINE: Patients are randomized to 1 of 2 arms. ARM I: Patients receive MIND counseling sessions over 30-60 minutes weekly for 4 weeks then over 15 minutes biweekly for 4 sessions over 8 weeks and follow a personalized diet for 12 weeks. Patients also wear a Fitbit and undergo dried blood spot collection on study and during follow up. ARM II: Patients receive general health recommendations counseling sessions over 30-60 minutes weekly for 4 weeks then over 15 minutes biweekly for 4 sessions over 8 weeks. Patients also wear a Fitbit and undergo dried blood spot collection on study and during follow up. After 6 month follow-up, patients may receive the MIND counseling sessions as in Arm I. After completion of study intervention, patients are followed up at 6 months.
