I used to drink an insane amount of diet soda (around 3 liters a day) but currently drink an average of less than a glass per month.
I have a hatred of liquid sugar, so I never drink the stuff with the HFC added...only diet. Regular sodas make me feel like I am growing hair on my teeth. (yuck!)
From what I understand, New York originally wanted a whole lot more than a ban on sodas for this...they wanted to ban anything containing any type of sugar or HFC (and sugar itself), including breakfast cereals, cookies, instant oatmeal, candy, snack cakes, pancake syrup, cake & muffin mixes, jellies & jams, etc...with plans on broadening it to included things with added fats and salt, in the future. If they had their way, there wouldn't be anything left for people to buy and food stamps would be a complete joke.
And while a ban from buying this stuff with food stamps will stop people from using food stamps to buy it, it won't stop people from buying it. Instead they will have to use their cash allowance they receive from the government to do it, money that would have been used to buy clothes for their kids, toilet paper, laundry detergent, etc.
They can't really stop buying it since the majority of the small juice box drinks approved for children to take to school in their lunch boxes are on the ban list. The remaining ones are insanely expensive. Each family needs to purchase 20 juice boxes per school aged child, per month, unless the school has cooking facilities and a free lunch program they are eligible for (some small schools in rural areas don't). Sold in packs of 3, that is about $10.50 per child, per month. If they use their food stamps to get the approved juices, it's about twice that. Considering the program only allows a max of about $75 per family member, per month, that's a pretty big chunk to force poor people to pay.
And the free lunch program isn't better than sending your kid to school with a peanut butter & jelly sandwich, a piece of fruit, and a HFC loaded juice drink (fortified with vitamin C), since the federal govt allows schools to do stupid stuff like call packets of relish and ketchup nutritious vegetables and substitute a few corn chips in place of bread.
