Gluten is a group of proteins found naturally in wheat, barley, and rye that gives dough its elastic, stretchy texture, trapping gas bubbles produced during fermentation and helping baked goods like bread rise properly.

For most people, gluten is a harmless part of the diet, digested without issue, and grain products containing it have been a dietary staple across many cultures for thousands of years.

Why Some People Need to Avoid It

For people with celiac disease, an autoimmune condition, consuming gluten triggers an immune response that damages the small intestine's lining, making a strict, lifelong gluten-free diet medically necessary rather than a lifestyle choice.

Separately, some people report symptoms like bloating or fatigue after eating gluten without testing positive for celiac disease, a condition often called non-celiac gluten sensitivity, though researchers are still working to fully understand its underlying mechanisms.
