Makes no sense. Its too complicated and would cost MORE money. Their are many reasons why this would be too complicated such as: allergies, medical restrictions and different cultures. To have such a control would be costly.
This is why the government hasn't put restrictions! Putting restrictions isn't going to cut spending either. These recipients will still get the same amount of assistance.
Food stamps should just go away IMO. The government was to be put in place for protection ....not for assistance.
EDIT: When I speak about restrictions I dont just mean pop and candy. Many people group certain cereals, quick meals, cookies, crackers, mixes and so forth which do have some food value. Some people need quick sugar in their diet for medical reasons. Some p Some people are allergic to certain ingredients so they need to be careful of what crackers or cereal to buy. Not everyone has the equipment or the ability to make everything home made...or the time because a lot of them work away from home. Can it be done? Probably. Is it necessary? NO THAT is my point. Its costly and a waste of time IMO
