QUIZ: What is gluten?
Answer: B.
Wheat-, rye-, or barley-based foods and beverages, including beer, typically contain gluten.
Bread, cookies, bagels, and pizza contain carbohydrates, often but not necessarily derived from wheat products. Many gluten-free versions of these foods now exist, made with gluten-free grains such as corn, rice, and quinoa.
Vegetables, fruits, nuts, and legumes contain no gluten whatsoever.
