It's become trendy to maintain a gluten-free diet, even for
people without allergies, but it's apparently not as trendy to
have any idea what gluten is.  Earlier this week, Jimmy
Kimmel—who's pro-gluten because he's pro-pizza—sent a crew to a
popular L.A. workout spot to see if people could explain what
they're not putting in their bodies. You won't be at all
surprised how it went.
