Background: Heart failure represents a clinical condition, characterized by cardiac damage, 
altered systolic and diastolic function, exercise intolerance as well as fluid retention. 
Foodstuffs are classified into several classes based on the variation in nutritional density. 
Aim: this work was aimed at identifying the effect of educational program on dietary 
diversity and nutritional status among heart failure patients. Subject & Methods: A quasi- 
experimental study. A purposive sample was 50 adult HF cases. Data were collected from 
cardiology department. Tanta University Hospital. Tools, three tools utilized within our 
research; Tool (1) Structured Interview Questionnaire it involved three parts. Part (A): Socio
demographic data. Part (B): Health relevant assessment sheet. (C): Laboratory investigation. 
Tool (2) Household Dietary Diversity Score. Tool (3) The Stanford Nutrition Action Program 
questionnaire: Part (1): The nutrition knowledge evaluation was determined utilizing a survey 
tool. Part (2): The nutrition self-efficacy scale. Results: It was revealed that score of nutrition 
related self- efficacy scale (100%) of study group stronger belief immediate and after three 
months implementation of program and a highly significant difference was documented in 
study group before and after implementation program (P=0.000).Conclusion: Our study 
addressed that HF cases exhibited low dietary diversity pre implementing the program and 
improved after implementation. Recommendations: The study's replication on a larger 
population. Applying educational dietary diversity program for HF cases rather than the 
traditional care, following the guidelines of care as well as illustrated patient education
