What is Gluten?
Gluten is a protein-rich substance made from wheat flour mixed with water and washed to remove starch and soluble materials. It contains about 75-80% protein and is unique to wheat grains. However, similar proteins in other cereals are often referred to as gluten in non-specialist contexts. These proteins, known as prolamins, include gliadin in wheat, hordein in barley, and secalin in rye.
Gluten proteins are primarily stored in the starchy endosperm of the grain, supporting germination and seedling development. These proteins form a network that gives the dough elasticity and structure, allowing it to rise and maintain its shape. Their distribution and composition vary within the grain, with higher concentrations located in the outer layers of the starchy endosperm.
Gluten is linked to celiac disease, an autoimmune disorder affecting approximately 1% of the population. Celiac disease inflames the small intestine, causing diarrhea, constipation, and malabsorption of essential nutrients like calcium and vitamin D. Consequently, this malabsorption can result in serious long-term health issues, including osteoporosis and anemia. This is particularly concerning for pediatric patients, who may also experience growth delays and short stature as a result.
Celiac disease pathophysiology involves a complex interaction between genetics and environmental factors, leading to an inappropriate immune response to gluten. This response leads to intestinal damage and villous atrophy, as gluten peptides trigger immune reactions and increase intestinal permeability.
A strict gluten-free diet (GFD) is essential for individuals with celiac disease (CD) to avoid worsening symptoms, further intestinal damage, and an increased risk of certain cancers. This diet requires the complete elimination of gluten-containing foods such as wheat, barley, rye, and oats while encouraging the intake of nutritious alternatives like fruits, vegetables, and gluten-free products. The rise in awareness and demand for gluten-free options has led to significant market growth, with sales exceeding $15.5 billion in 2016.
