Paired t-test, independent t-test and Wilcoxon signed-rank test were performed for comparing the results of before and after implementing nutritional education.

Results: Mean of knowledge after intervention (18.75 (S.D.=0.55)) was statistically significant higher than before intervention (15.65 (S.D.=2.53)) (p<0.001). After conducting nutritional education, patient’s attitude toward food consumption behavior was better than before statistically significant (p< 0.001). Also, percentages of high level of food consumption behavior score (41-55 scores) before and after the interventions were 40.0 and 80.0 %, respectively. Mean score of practice after the intervention (45.40 (S.D.=5.05)) was statistically significant higher than before the intervention (38.30 (S.D.=8.05) (p<0.001).
