The purpose of this study is to refine the classification of the effectiveness of the DASH diet for outpatient heart failure (HF) management, using behavioral, clinical, and laboratory correlative science approaches.
The overall objective of this pilot study is to refine the classification of the effectiveness of the DASH diet for outpatient HF management using behavioral, clinical, and laboratory correlative science approaches. The investigators will integrate the use and evaluation of DASH diet nutrition education in a clinical population using a pragmatic study approach. The investigators will assess dietary behavior change. The investigators will assess the medical effectiveness of the DASH diet to improve patient symptomology and clinical biomarkers. Exploratory investigations will involve metabolomics analyses of plasma samples for biomarker discovery of clinical phenotypes in HF patients, to characterize metabolic profiles related to dietary exposure.
