These days, whole supermarket aisles are devoted to products that are gluten-free. Easy access to these foods is a blessing for the two million Americans who struggle with celiac disease and can t tolerate gluten. But the gluten-free movement is gaining followers for other health reasons.

Paul Daniel has food allergies and knows the consequences.

When I lay down at night I d have asthma symptoms, or I would have repeated migraines and get ear infections repeatedly, said Daniel.

Once he stopped eating pizza and pasta, he felt better.

I eat a lot more rice and Indian dishes now, said Daniel.

Those with wheat allergies and especially celiac disease cannot tolerate the protein gluten. For them, it damages parts of the small intestine and interferes with absorption of nutrients. That can mean a lot of stomach pains. But that s not all.

We re seeing more and more people come to us going gluten-free not because they have been diagnosed with celiac but they are presenting with other medical conditions, joint pain, eczema, unexplained pain, said Amanda S. Holiday, registered dietician.

Gluten-free doesn t necessarily mean eliminating favorite foods. Pizza is still game - one recipe we found is made from potato tapioca millet and cornstarch.

There are more grains that are gluten-free than those that have gluten. The typical American diet doesn t know about them, said Holiday.

But be careful. Many gluten-free products now on the market contain plenty of calories, but very few vitamins or minerals.

If you plan to go gluten-free, it s healthier to avoid highly processed foods. And make sure you re getting enough iron, fiber, and B vitamins in the rest of your diet.
