T-test was done to assess the differences between food secure and food insecure groups by intake of the different food groups. The food items were grouped according to MyPyramid [USDA, 2005).

Means [±SD) are given unless indicated otherwise.

The p values compare the means frequency of consumption of the different food groups per week between food secure and food insecure adolescents and the maximum value for the group is 1.

FS = food Secure, FIS =  Food Insecure.
