Gluten is a group of proteins found in certain grains that play a crucial role in giving dough its elasticity and texture. For many people, gluten poses no health issues. However, for those with gluten-related disorders, consuming gluten can lead to various health problems. Understanding what gluten is and where it is found can help individuals make informed dietary choices and manage their health effectively.
What is Gluten?
Defining Gluten
Gluten is a composite of proteins found in wheat and related grains. The two main proteins in gluten are gliadin and glutenin. These proteins work together to:
- Provide Elasticity: Gluten gives dough its stretchiness, which helps it rise and maintain its shape.
- Improve Texture: It contributes to the chewy texture of baked goods, making them more enjoyable.
Gluten and Health
For most people, gluten is a harmless part of the diet. However, gluten can cause health issues for individuals with specific conditions:
- Celiac Disease: An autoimmune disorder where ingestion of gluten leads to damage in the small intestine. Symptoms include diarrhea, abdominal pain, and nutrient malabsorption.
- Non-Celiac Gluten Sensitivity: Individuals experience symptoms similar to celiac disease but without the autoimmune response or intestinal damage.
- Wheat Allergy: An allergic reaction to proteins in wheat, including but not limited to gluten.
Foods Containing Gluten
Wheat-Based Products
Wheat is the primary source of gluten and is found in many common foods:
- Bread: Most traditional breads, including whole wheat, white, and multigrain varieties, contain gluten.
- Pasta: Regular pasta made from wheat flour contains gluten. This includes spaghetti, macaroni, and lasagna noodles.
- Cereals: Many breakfast cereals contain wheat or wheat-derived ingredients.

Besides wheat, several other grains also contain gluten:
