Americans spend a lot of money trying to stay healthy; often on things that don't have a lot of science behind them.  Things like fish oil pills are sold by the thousands every day, but their health benefits aren't proven.  Consumer Reports tested 9 anti-aging serums and didn't find any overwhelming results even though sales are in the billions of dollars.

So what about one of the latest trends, gluten-free foods?  Is it a benefit to spend the extra cash to try to avoid these evil glutens?  Well, let me be clear that I am not a doctor and it's not my intention to dish out medical advice, but many of the smart folks who are qualified say that there are no real benefits to most people.  If you have celiac disease or have been advised by a doctor to avoid gluten, I'd say you should probably take that advice.  If, however, you just started paying more for things labeled "Gluten Free" because you think that gluten is inherently bad, you might just be throwing away money. The fact that there is no test for gluten intolerance makes it a bit of a guessing game, but this article might shed some light on the subject.  Even if you've gone gluten-free and noticed some good changes, it might be something else you're avoiding that is giving you the positive results.
