The nutritional quality of each person was determined based on the 2015 healthy eating index. Results: The mean age of subjects (48.1±8.28) and mean of HEI of individuals was 53.81 ± 7.37, which indicates the average quality of nutrition. 65.74 people are of medium HEI and only 0.05 have good nutrition. The most effective variable is HEI (r=0.14) for SES and education level is (r=0.124). The weak HEI is correlated with improving SES and has a direct and moderate relationship with SES (P <0.001).Conclusion: SES directly affects people s nutritional quality.
