4. Coors Light

Coors Light is yet another super-popular brew in North America, given its skillful marketing and smoothness as a light beer. Indeed, the company’s marketing strategy, predicated on the glaciers that turn certain colours based on the coldness of the beer, is genius, and it empowers consumers, who like to feel they are drinking the coldest, freshest beer. Unfortunately for drinkers of Coors Light, this is also another beer that uses GMO corn syrup as a sweetener. Given that the beer is so easy to drink, and easy to drink in volume, consumers should be wary of this beer’s potentially harmful ingredients.

3. Pabst Blue Ribbon

Pabst Blue Ribbon, colloquially referred to as PBR, is a classic beer, whether haters like to admit or not. The original German beer to make its way across the pond to North America, Pabst Blue has enjoyed a good deal of success for decades. Unfortunately for PBR’s loyal votaries, the beer is made with GMO corn and corn syrup.
