If you are not a celiac, there are numerous reasons not to jump on the gluten-free fad. Gluten-free products are nutrient poor, they're high in sugar, contain preservatives and are made with refined oils. That's not healthier and it's why Lady Gaga got fatter going gluten-free, even though she claimed it was a diet plan.

And if you are celiac, buying gluten-free labels in a store can be dangerous, because they can still have trace amounts of gluten. Like 'organic' food and its dozens of synthetic ingredients and processes allowed, 'gluten-free' does not mean "100%" gluten-free.
