Intolerance to gluten is a wheat-related condition. Some of the symptoms include pain and bloating in the belly after consuming foods that have gluten in them. Foods that have gluten will have wheat, barley, or rye in them.

According to researchers, gluten intolerance or non-celiac gluten sensitivity is similar to celiac disease in that the person can't consume gluten, however, they are two distinctly separate conditions.

If a person does have gluten intolerance, it is controlled by living on a gluten-free diet. This is challenging as many of the everyday foods that are consumed naturally contain wheat.

Today, foods are labeled for wheat and other gluten content. This helps a lot over previous decades. Nutritionists and dieticians can also help.
