The research results showed that after participated in the program the experimental group had significantly higher levels of knowledge about healthy food consumption, perceived self-efficacy to consume healthy food, and appropriate healthy food consumption behavior than before the experimentation and than the comparison group (p<0.05). In conclusion, the healthy food consumption promotion program applying the Social Cognitive Theory in designing the learning activities was effective in increasing knowledge and perceived self-efficacy to consume healthy food, and had appropriate food consumption behaviors of grade 8 students.
