Only one third of students consumed daily water adequately (≥8 glass) and when the daily water consumption increased, nutrition literacy increased (p<0.05). Fast food consumption had a significant effect on nutrition literacy (p<0.05). Nutrition literacy was higher among mostly food label users (p<0.05). Nutrition literacy was found to be significantly higher among the utilizers health care workers as a nutrition source (p<0.05).
