“Celiac” is a popular term today, often paired with “gluten free.” Celiac disease is hereditary and occurs when the lining of the small intestine gets inflamed and damaged, triggered by an immune reaction some people have when they eat gluten. Gluten is a protein in wheat, rye and barley. A damaged small intestine can’t absorb nutrients from food. Left untreated, this can lead to other serious health problems. Celiac disease can develop at any age and is estimated to affect 1 in 100 people. People with a first degree relative having celiac disease have a higher risk of also developing it. 60-70% of celiac disease occurs in women.
