Gluten's Role
People with a condition called celiac disease must avoid a protein called gluten, which is found in certain grains. In these cases, eating gluten causes damage in the small intestine.
Concern about gluten’s effects in people without celiac disease has become trendy in recent years, McGee says. But people can be sensitive to gluten even if they don’t have celiac disease. In some cases, this gluten sensitivity can cause a skin rash, she tells WebMD. However, the rash related to gluten sensitivity, called dermatitis herpetiformis, is seen mainly in people with celiac disease.
A low-gluten diet can make a lot of nutritious foods – such as whole-wheat bread – disappear from your plate. If you start a trial period without gluten, be sure to talk with your doctor first.
