Celiac Safety Glossary
- Celiac disease
- Celiac disease is a serious autoimmune disorder in which ingesting gluten β a protein found in wheat, barley, and rye β triggers an immune response that damages the small intestine's villi, affecting approximately 1 in 100 people worldwide according to the Celiac Disease Foundation.
- Gluten
- Gluten is a family of storage proteins (prolamins and glutelins) found naturally in cereal grains like wheat (including varieties like spelt, kamut, and farro), barley, and rye, which acts as a binder to give food elasticity and shape.
- Cross-contamination
- Cross-contamination (or cross-contact) occurs when gluten-free food comes into contact with gluten-containing food or surfaces β such as shared cutting boards, toasters, fryers, or utensils β rendering otherwise safe food dangerous for people with celiac disease.
