This is common sense and should have never been allowed in the first place.
It started out that way.
It's been that way as long I as I can remember back to the 90s.
I had a disabled relative on food stamps in the '60s. She got govt surplus food (cheese loaf dried eggs, dried milk...) and food stamps that were not redeemable for processed foods, soda, candy, crackers, etc. Since then it has morphed into what it is today.
