Gluten-free diets gaining in populatiry

The USA Today had an article called Gluten-free diets gaining in popularity. Gluten is a protein found in wheat, rye and barley. It causes some people serious health problems. But people with celiac disease, the best-defined and most severe form of gluten intolerance, don't seem to be the only ones buying the gluten-free beer and brownies. Marketers estimate that 15% to 25% of consumers want gluten-free foods- though doctors estimate just 1% have celiac disease says Cynthia Kupper, the executive Director of the non-profit Gluten Intolerance Group of North America. Dee Sandquist, a registered dietitian and spokeswoman for ADA, says Gluten Free Diets are catching on a colleges. Both of the woman above believe this is a fad. People feel better about eating without gluten because they consume fewer fast and processed foods, which tend to have gluten. The trend has produced more gluten-free versions of foods the truly intolerant would have to give up. There are also disadvantages, you are shorting yourself on vitamins, the foods are expensive, and if the diet is poorly planned it can be fattening.
The Restaurant I work has a pretty big gluten free menu, which attracts alot of people. They are the same exact items on the regular menu just modifiers the servers have to put in. I have eaten gluten-free products at work but not because I wanted to use this as a new diet. I don't like croutons on my salad and I don't usually use the house vinaigrette or caesar dressing so my salad is then gluten free, for example. I also usually don't get butter on my vegetables because they use an excessive amount. In the portioned vegetable butter is vegetable seasoning which is not gluten-free. I'm sure I have consumed alot more gluten-free items also but never intentionally.
Have you tried gluten-free products? If so, why?
