Brief Summary:
This clinical trial tests whether a new dietary pattern that consists of foods that lower the blood insulin response can reduce breast cancer risk in high-risk women In a large group of patients this new dietary pattern was associated with reduced risk of multiple cancers and reduced risk of long-term weight gain Parts of this new dietary pattern are quite different from typical dietary recommendations and much education is needed Overall compared to the typical American diet this new dietary pattern is moderately low in total fat and saturated fat low in protein from animal foods but high in protein from plant sources high in fruits and vegetables high in whole grains and high in dietary fiber We will determine if a low-insulinemic dietary pattern intervention is feasible and effective in reducing breast cancer risk in high-risk women
Detailed Description:
PRIMARY OBJECTIVE
I Evaluate the feasibility of translating the low-Empirical Dietary Index for Hyperinsulinemia EDIH dietary pattern intervention from epidemiologic cohorts to the clinic in a single arm phase I trial among postmenopausal women at high risk for cancer and evaluate safety
SECONDARY OBJECTIVES
I Determine the change in patient reported outcomes PRO under the Low-EDIH dietary pattern at 12 weeks from baseline
II Evaluate the change in cardiometabolic biomarker profiles at 12 weeks from baseline a glycemic control and insulin response parameters measured using fasting glucose insulin hemoglobin A1C C-peptide HOMA-IR HOMA-B and IGFBP-1 IGFBP-2 b lipid profiles total cholesterol triglycerides TG low density lipoprotein LDL higher high density lipoprotein HDL
III Assess change in circulating biomarkers associated with risk of breast cancer and low-grade chronic inflammatory state including C-reactive protein CRP TNFalpha-R2 IL-6 and leptinadiponectin ratio at 12 weeks from baseline
EXPLORATORY OBJECTIVES
I Collect stool samples and process for subsequent assessment of changes in the fecal microbiome structure and function related to the low-EDIH dietary pattern intervention
II Collect 24-hour urine samples and process for subsequent assessment of changes in targeted and non-targeted metabolomics and lipidomics alterations related to the low-EDIH dietary pattern intervention
OUTLINE
Participants receive the low-EDIH dietary pattern intervention consisting of 6 group nutrition education sessions focusing on foods to prioritize within each food group food combinations food preparation discussion simple cooking demonstrations food tastings smart shopping advising and a questionanswer period over 2 hours each at weeks 0 1 2 3 5 and 6 Participants also attend 3 in-person or virtual individual nutrition counseling and motivational interviewing sessions over 30 minutes each at weeks 3 and 5 between weeks 7 and 9 and between weeks 9 and 11 Participants also wear an activity tracker and undergo blood sample collection on the study
After completion of study intervention participants are followed up in week 12
