The gluten free diet has become ever growingly popular in the United States in the past few years. Some people can’t eat gluten for medical reasons due to Celiacs Disease which affect 1 out of 133 people in the US, which is totally understandable. But then there are people who follow this gluten free diet trend yet they don’t even know what gluten exactly is. So Jimmy Kimmel and his crew decided to put some random non-medical gluten free dieters on the spot and ask them what exactly is gluten. And their reactions are priceless!
