Do you know why some food labels say gluten-free?

Hi, I'm Dr. Griffin Rodgers bringing you Healthy Moments. I'm the director of the National Institute of Diabetes, Digestive, and Kidney Diseases at NIH.

Gluten is a protein found in foods made from wheat, rye, and barley. Gluten-free foods are important for people with Celiac disease. More than two million people in the U.S. have Celiac disease, which damages the small intestines and interferes with the body’s ability to absorb nutrients.

People with Celiac disease can have a wide range of symptoms including diarrhea, weight loss, fatigue, and an itchy skin rash, or they may have no symptoms. The good news is that, once diagnosed, a gluten-free diet is usually an effective treatment.

You should also know that our institute conducts and supports research on Celiac disease.
