Oddly enough the gluten free ones are proudly labeled gluten free.
If you are gluten free because you can't tolerate gluten, that labeling is very helpful.
As someone who is gluten free because I can't tolerate gluten, I would add that, for those who don't have that issue, gluten free food is not always the healthiest choice. In particular, gluten free baking is tricky, and gluten free baked goods are generally much higher in sugar.
