Army mandatory meal-plan institutionalism?

Alrighty here's the deal I'm a soldier on Ft. Lee 109th living in the barracks. The dfac is horrible. The food they cook is literally unedible. They mostly serve , two times a week the mainline will be nothing but chicken. I hate chicken but i'll eat it anyway since i'm hungry and woe and behold it's not even cooked all the way. It happens every fricken time. The only thing I will eat from there is the burgers which are good if you put enouph stuff on them. Since arriving here in fort lee i have gained 20 pounds, am constantly having stomach problems and getting constipated. I tried talking to my 1SG but he says because i live in the barracks i have to be on the meal plan. So in addition to paying 295.83 every month for food i don't eat i'm paying out of pocket for anything that i can cram into an itty bitty refrigerator and it's about to put me into debt. Anyway my question is this, isn't forcing me to spend my money on the dfac institutionalism which is unconstitutional?
