In 2009 research showed between 0.5 and 1.0 percent of people in the US and UK are sensitive to gluten due to celiac disease. So people with Celiac disease have to stick to gluten free diet to avoid unexpected side effect caused by consumption of gluten.

Non-celiac gluten sensitivity: Some people may be sensitive to gluten but do not have celiac disease and feel better on a diet with less gluten. However, there are no specific symptoms confirmed. Non-celiac gluten sensitivity also drives more people to gluten free diet when people believe that they feel better when eating gluten free.
