Glutens are proteins that occur naturally in certain cereals such as wheat, spelt, rye and barley. Gluten, for instance, make bread fluffy. Read more about gluten below.

what are glutens?

Glutens are proteins that occur naturally in certain grains such as wheat, spelt, rye and barley. Gluten, for instance, make bread fluffy. Gluten are digested in your gastrointestinal system. When gluten cannot be properly digested in the gastrointestinal system, they are a risk factor for the formation of gas in the intestines.

For people with celiac disease, the body reacts violently to the intake of gluten. The body produces antibodies that attack the body’s own cells. This causes an inflammatory reaction in the lining of the small intestine, damaging it. A damaged intestinal wall cannot absorb nutrients as effectively, causing deficiencies.
Coeliac disease is a serious condition, seeking medical help is important here. This page is not about celiac disease.
