Understanding Gluten
Essential knowledge for anyone with celiac disease, gluten sensitivity, or following a gluten-free diet.
What Is Gluten?
Gluten is a family of storage proteins found naturally in wheat, barley, rye, and triticale. The two main proteins in gluten are glutenin and gliadin — gliadin is responsible for most of the negative health effects in people with celiac disease.
When flour is mixed with water, gluten proteins form a sticky, elastic network that gives bread its chewy texture, helps dough rise, and provides structure to baked goods. This is why gluten-free baking requires different techniques and substitutes.
For the approximately 1 in 100 people worldwide who have celiac disease, even trace amounts of gluten (as little as 20 parts per million) can trigger an autoimmune reaction that damages the small intestine's lining, leading to nutrient malabsorption and a wide range of symptoms.
Who Needs to Avoid Gluten?
Celiac Disease
An autoimmune disorder where gluten triggers immune attacks on the small intestine. Affects roughly 1% of the population. Requires strict, lifelong avoidance of all gluten — even trace amounts from cross-contamination.
Non-Celiac Gluten Sensitivity
Causes symptoms similar to celiac disease (bloating, fatigue, headaches) but without intestinal damage. Estimated to affect 6–7% of the population. Diagnosis is by exclusion after ruling out celiac disease and wheat allergy.
Wheat Allergy
An allergic reaction to proteins in wheat (not limited to gluten). Can cause hives, difficulty breathing, or anaphylaxis. Most common in children and often outgrown by adulthood.
Dermatitis Herpetiformis
A chronic skin condition directly linked to celiac disease. Causes intensely itchy blisters, typically on elbows, knees, and buttocks. Resolves with a strict gluten-free diet.
