1. Understanding Gluten: The Basics

What exactly is gluten, and why is it important to know where it’s hiding? Gluten is a protein found in wheat, barley, rye, and triticale. It gives elasticity to dough, helping baked goods maintain their shape. For some people, gluten can trigger adverse health reactions, making it essential to identify gluten-containing foods.

1.1. What is Gluten?

Gluten is a group of proteins, specifically gliadin and glutenin, found in certain grains. These proteins give dough its sticky, elastic texture, which is essential for baking. Gluten allows bread to rise and gives it a chewy consistency. However, not everyone can tolerate gluten, leading to the need for gluten-free diets. According to the Celiac Disease Foundation, gluten triggers an immune response in individuals with celiac disease, damaging the small intestine.

1.2. Why is Identifying Gluten Important?

Identifying gluten in food is crucial for individuals with celiac disease, non-celiac gluten sensitivity (NCGS), wheat allergies, and other related conditions. Consuming gluten can lead to a range of symptoms, from digestive discomfort to severe intestinal damage in those with celiac disease. A gluten-free diet is often recommended to manage these conditions and improve overall health. FOODS.EDU.VN provides resources to help you understand these conditions and manage your diet effectively.

1.3. Common Sources of Gluten

Gluten is commonly found in wheat, barley, rye, and triticale. These grains are used in a wide variety of foods, making it important to be vigilant about reading labels and understanding ingredients.

Common Gluten-Containing Grains:
