Americans spend USD 4.2 billion on gluten-free food each year, a new study has found. Gluten-free food is suggested to people with Celiac disease. An immune reaction is triggered in people with the condition because of eating gluten - a protein present in wheat, barley, and rye. These proteins are very good for health, but people with Celiac diseases are advised to avoid those.

However, it is surprising to know that many people around the world are increasingly avoiding gluten enriched food, despite the fact that they are not suffering from Celiac disease. As per figures of Food Allergy Research and Education, only 1% of the US population actually suffers from Celiac, but still many people prefer to declare themselves eating gluten-free food.

As a result, $4.2 billion are spent by the Americans on gluten-free food every year. Many people have wrong notions about eating gluten, like consumption of gluten increases body weight or gluten is unhealthy for the body.

Several kinds of gluten-free foods are available in the market and people are also getting more and more aware about benefits of eating gluten free foods. But as a matter of fact, majority of people wrongly believe that they are allergic to gluten and it is also very difficult to convince those people that they are not having Celiac disease, so they should not deprive themselves from benefits of eating gluten-enriched foods.
