In both groups, the food behavior which includes the consumption of fat (p=0.803) and fiber (p=0.926) did not differ, whether from food or natural products. There is no significantly difference in body image between the two groups (p=0.463).Conclusion: Between health and non-health students have different perceptions of nutrition claims, but there is no difference in food behaviours and body image between the two groups.
