9. Michelob Ultra

Michelob Ultra is another beer that ceaselessly intrudes upon our lives via commercials on television. Unfortunately for Michelob Ultra drinkers, this beer contains GMO dextrose, another genetically-modified sweetener akin to corn syrup. GMO dextrose can play tricks with your blood sugar and lead to the same kinds of ailments that GMO corn can lead to. Since beer is already high in calories, drinkers should beware of consuming anything that might seriously affect their blood sugar levels.
