Coeliac disease affects several million people in the world. For these people eating a protein called gluten can lead to the destruction of villi. If the villi are destroyed, people with coeliac disease may not grow properly. Suggest why.

It's because villi carries nutrients around your body, and if your villis are destroyed, your body will have lack of nutrients
