I have a friend who receives food stamps and there is not even enough for her to spend 50 bucks a week on food...it's more like 20 bucks. Of course benefits range greatly depending on your situation. But how can one eat healthy on 20 bucks a week?
My suggestion would be to look into Angel Food Ministries(google it) they provide a lot of food for little money and they always have a fresh fruit and veggie box, they do indeed take food stamps and it's a good way to stretch your dollar. You can get well over a months worth of healthy food for about 100 bucks. BTW there is no income requirement all you have to do is order and go pick up your food.
