Jimmy Kimmel hit the streets to ask people who are on a gluten-free diet if they even know what gluten is. What's sad is that none of them had a clue.

Let me be the first to raise my hand and say that I have no idea what exactly gluten is, I just know that word on street is that it's not good for us. Let me also say that while I'm not sure what gluten is, I believe anyone on a diet that is free of it should at least know what it is.

So what exactly is gluten?

According to Huffington Post,

For what it's worth, gluten is composed of the gliadin and glutenin proteins and is responsible for the elasticity of dough. Research has found that one of the better-known forms of gluten intolerance, celiac disease, affects 1 in every 141 people in the United States.

Every day, we see things like "gluten-free" and "organic" and automatically feel the need to purchase those items over others that are just as good—or in some cases just as bad.

The truth is, this type of attitude or behavior doesn't start or stop with gluten. Do you know anyone that is totally into something that they really have no clue about?

If so, share this video with them. :)
