When I was growing up, I never heard of anyone with gluten/wheat intolerance. I'm sure it existed, but no one, even the medical community didn't talk about it. Be that as it may, a lot of foods today, particularly snack foods, bear the label of "gluten-free". However, for the gluten-intolerant, dining out or, say eating at an office potluck, could be an unpleasant experience. I found out about Nima, the senor that detects gluten in food. This is a real product, take a look!
