Gluten Quiz Answers
1. b) Not all grains contain gluten. People who cannot tolerate gluten can eat gluten-free grains. However, it’s also possible to have an intolerance to grain for reasons other than gluten, and then, even gluten-free grains need to be avoided. Flours made from coconut, nuts, and seeds are grain-free options for baked goods, and there are a growing number of grain-free products made with such flours.
2. b) While it’s true that quinoa doesn’t contain gluten, it’s actually a seed rather than a grain. Because it’s often eaten or used in recipes in place of grains, it tends to be viewed as a gluten-free grain.
3. b) A packaged food without grains may contain gluten for two reasons: Gluten may be added as an ingredient for texture, or gluten may be introduced through cross-contamination. Many foods we don’t associate with grains, such as soups, sauces, and dressings, contain added gluten. However, foods labeled “gluten free” do not contain gluten. In nature, gluten is not present in meat, fish, vegetables, nuts, seeds, and fruit, and is unlikely to have contaminated fresh versions of these foods, unless flavoring or marinades have been added.
4. a) Oats are naturally gluten-free. However, they may become contaminated during growing, harvesting, or processing. Some companies take care to produce gluten-free oats, and label them as such.
5. d) Buckwheat is naturally gluten-free. All of the others contain gluten. Kamut is considered an ancient grain and possibly healthier than today’s wheat, but it is still a type of wheat, so it does contain gluten.
6. c) Bulgur naturally contains gluten. The others do not, but it’s a good idea to check labels for a “gluten-free” description to make sure they haven’t been contaminated with gluten during harvesting or processing.
7. b) Testing for gluten sensitivity, rather than celiac disease, is controversial in conventional medical circles, but integrative and naturopathic physicians can do such tests, and some labs are specially equipped to perform them.
