I've heard that a lot of people are taking a gluten-free diet. What is gluten and why do so many people avoid it?

Gluten is a protein found in wheat, barley, rye, and oats. It’s the main component of wheat flour and is responsible for giving bread its structure. People who have celiac disease must avoid foods containing gluten because their bodies cannot properly digest it. Other people may choose to avoid gluten for health reasons, such as reducing inflammation or improving digestion.
