14. Budweiser

Budweiser—also known as the “King of Beers”—is one of the most popular mass-produced beers in North America, and it is a sponsor of major athletic events and leagues like the NFL. As such, most beer drinkers have probably had one of these at one time or another. Budweiser, though, is made with genetically modified corn (GMO). Since its rise in the 1980s, as the biotechnology behemoth, Monsanto, began to genetically modify corn to withstand herbicides without a drop off in crop supply, GMO corn has been linked to a host of health problems. It encourages the overdevelopment of a white blood cell called eosinophil, which, when overproduced, attacks our bodies’ organs, nervous and cardiovascular systems, and skin. As such, people should avoid consuming too much GMO corn.
