My parents pay for my food because I still live with my mom (I'm a high school senior), so I could theoretically eat sticks of butter all day every day if I wanted to, but I don't because I have self control and I'm not a sorry excuse for a human being like some people I could mention...  But even if I did have only 30$ a month for food, fruits and vegetables here are dirt cheap. I could make three huge bowls of salad (I'm talking 500 calories worth of raw veggies in each bowl) for the equivalent of $4.5 because of how cheap produce is here. Even chicken is cheap! And yet we have a 72% obesity rate...
