Soda is not food and should not be allowed. The purpose of food stamps should be to keep you alive until you get back on your feet--not to let you eat and drink whatever you want. And certainly not to let you eat garbage so taxpayers will then have to pay for your healthcare.
Bread, lunch meat, and cheese go together because it's cheap and quick. Lunchmeat packages are like... 50 cents a pop
Milk is okay but cereal is a waste. It is the single most expensive meal item per serving that you can purchase (because you need milk which adds to the cost).
Soda... no surprise. Taste, sugar, calories, as low as 75-88 cents for a two liter. Lowest cost for the highest calories.
Bagged snacks are comfort foods.
