Gluten-free refers to a diet that excludes gluten, a protein found in wheat, rye, and barley, as well as their derivatives. For people with celiac disease, an autoimmune disorder, or gluten intolerance, ingesting gluten can lead to damage to the small intestine and adverse health effects. Therefore, the gluten-free diet seeks to avoid such intakes.
Gluten-free diets have also become popular among those who don't necessarily have a medical condition, as part of a healthy lifestyle choice. Gluten-free foods include naturally gluten-free foods such as rice, corn, potatoes, beans and legumes, as well as specially produced gluten-free options for bread, pasta and baked goods. It is important for those choosing a gluten-free diet for health reasons to ensure they are getting adequate nutrients, as some gluten-free options may lack fiber and key nutrients found naturally in gluten-containing grains.
