1. What Exactly is Gluten and Why Should I Care?

Gluten is a family of proteins found in grains like wheat, barley, rye, and triticale (a hybrid of wheat and rye). These proteins give dough its elasticity, allowing baked goods to rise and maintain their shape. While gluten is harmless for most people, it can cause significant health issues for those with celiac disease, non-celiac gluten sensitivity (NCGS), or wheat allergy, as noted by the Celiac Disease Foundation.

1.1. The Science Behind Gluten’s Impact

For individuals with celiac disease, consuming gluten triggers an autoimmune response that damages the small intestine. This damage impairs the body’s ability to absorb nutrients, leading to various health complications, as highlighted by the American Gastroenterological Association. NCGS, on the other hand, doesn’t cause the same intestinal damage but can still lead to unpleasant symptoms like bloating, abdominal pain, and fatigue. A wheat allergy involves an immune response to wheat proteins, which can manifest as digestive issues, skin rashes, or even respiratory problems, according to the American College of Allergy, Asthma and Immunology.

1.2. Common Foods That Contain Gluten

Bread: Most commercially produced breads, including white bread, whole wheat bread, and rye bread, contain gluten.
Pasta: Traditional pasta is made from wheat flour, making it a gluten-rich food.
Cereals: Many breakfast cereals contain wheat, barley, or rye.
Baked Goods: Cakes, cookies, muffins, and pastries typically contain gluten unless specifically made with gluten-free flour.
Sauces and Gravies: Some sauces and gravies are thickened with wheat flour.
Beer: Most beers are made with barley, which contains gluten.

2. Which Grains Contain Gluten?

Identifying gluten-containing grains is essential for anyone following a gluten-free diet. Here’s a detailed breakdown:

2.2. Hidden Sources of Gluten in Grains

Gluten can sometimes be found in unexpected places, especially when grains are processed. Here are some examples:

Oats: Although naturally gluten-free, oats are often processed in facilities that also handle wheat, leading to cross-contamination. Look for certified gluten-free oats.
Couscous: Made from semolina, a type of wheat flour.
