Cola i USA innehåller socker från majs. Detta pga att USA tillverkar alldeles för mycket majs (överskott), Även kor matas med majs osv.
"Does Coca Cola use sugar cane or corn syrup?"
"Depends where you buy the Coke.
In the US, it's made with corn syrup but in most places outside of the US, it's made with sugar. In the US though, you can find Coke made with real sugar around the time of the Jewish holiday of Passover."
