response to the banning soda purchases with food stamps

I cant agree with everyone, though i do agree with Christpoher Greenslate on his article "On a Dollar a Day". he states towards the end of his article that "

People on food stamps know what is healthy and what isn’t. But this doesn’t help them unless local governments are doing everything they can to ensure that those who are eligible are getting access to the benefits they so desperately need." I think everyone should know what is healthy now since we are in the 21st century, we've seen what cuases obesity and health issues, and where our food comes from.i dont think that soda pruchases with food stamps should be banned , becuase not every can afford a $2 coke . Greenslate did say people on food stamps do know what is healthy and what isn't. would banning soda really make a difference? if they ban soda with food stampos i think they sould just banned soda period.
