What is gluten

What is Gluten?

Gluten is a naturally occurring protein found in many grains, particularly wheat, barley, and rye. It consists of two main protein types: glutenin, which provides elasticity, and gliadin, which provides viscosity. Together, these proteins create the characteristic texture and structure found in bread and other baked goods.

Function in Food

Gluten plays a crucial role in baking and food preparation. When mixed with water, gluten forms a network of proteins that traps gas bubbles, allowing dough to rise and bread to develop its characteristic fluffy texture. This same property makes gluten valuable in pasta production and other grain-based foods, contributing to desirable firmness and bite.

Celiac Disease

Celiac disease is an autoimmune condition affecting approximately 1% of the population. In people with celiac disease, consuming gluten triggers an immune response that damages the small intestine's lining. This can lead to nutrient malabsorption, digestive issues, fatigue, and various other health complications. The only treatment is strict lifelong dietary avoidance of gluten.

Gluten Sensitivity and Wheat Allergies

Beyond celiac disease, two other conditions involve gluten or wheat:

• Non-celiac gluten sensitivity (NCGS) causes symptoms similar to celiac disease but without intestinal damage or immune markers
• Wheat allergy is an immune response to wheat proteins that differs from celiac disease

Gluten-Free Living

The gluten-free market has expanded dramatically in recent years, offering alternatives including rice flour, corn flour, almond flour, and specialized gluten-free breads. Certified gluten-free products contain less than 20 parts per million (ppm) of gluten, meeting international safety standards. However, naturally gluten-free whole foods like fruits, vegetables, meat, and rice remain the foundation of balanced gluten-free diets.

Hidden Gluten Sources

Gluten extends beyond obvious sources like bread and pasta. It can hide in sauces, processed foods, medications, and supplements due to grain-based ingredients or cross-contamination during manufacturing. People managing celiac disease or gluten sensitivity must carefully read labels and verify food preparation practices.
