FYI, you can just go to the grocery store around passover and stock up on "Coke with real sugar" (find the ones with yellow lids) for the exact same price as "Coke with corn syrup". I don't find it tastes any different, but I prefer it because real sugar is better for you. Well, more like "mildly less bad for you", but still.

If you want to know how to get food without garbage in it, go find some non-rich people who have moral or religious restrictions against the garbage, and then do what they do. It actually works.
