There's definately two equal views on the whole non-medical gluten free. It's great because it created additional market for even large companies to go "Hey, we should do this" which of course gives us greater options. The down side is that the underinformed think that it is just a fad diet.
The only reason it was originally healthier because people were limited to vegetables, meat and rice. No fried foods, no processed foods, no empty calories, few refined foods.
Now that the companies have created this, there are options, even if they are empty calories, but there's definately things like cake and breads that are easy to get from about any store. No need to make clam chowder, now you can just pop a can from progresso.
I still think I'd be doing gluten free beer for the challenge of making something tasty, more than anything else if I didn't have a reaction, plus for the gluten free people I know.
