Should food stamps be used to buy junk food?

Florida seems to be joining the movement in other states to limit what food stamps can be used for. Why not limit it even further to really basic foods that aren't already? For example, not allowing the money to be spent on TV dinners.

Florida's poor can use food stamps to buy staples like milk, vegetables, fruits and meat. But they can also use them to buy sweets like cakes, cookies and Jell-O and snack foods like chips, something a state senator wants stopped.
Sen. Ronda Storms, R-Valrico, also wants to limit other welfare funds, known as Temporary Assistance For Needy Families, from being used at ATMs in casinos and strip clubs and anywhere out of state. The bill comes after reports that the debit cards welfare recipients now receive were used in those places, as well as locations in Las Vegas and the Virgin Islands in a small percentage of cases, but the state does not track what items were purchased.
The bill recently passed a committee. A companion bill in the state House companion is being considered by a subcommittee.
The bill would also require the state to launch a culturally sensitive campaign to educate people about the benefits of a nutritious diet. Supporters say it would help recipients follow healthy eating habits and prevent taxpayer funds from being used to purchase luxury foods like bakery cakes when they can whip up a cheaper box mix.
"Most individuals using public assistance dollars are using the funds to get by and to provide for their families. However, we should do what we can to prevent dollars intended to help Florida's poorest families from being spent in the wrong places," Storms said in a statement. . . .
