Final answer:
There are six gluten-free grains suitable for those with celiac disease or gluten sensitivity: rice, oats, corn, quinoa, buckwheat, and millet. These should be chosen carefully to ensure they are gluten-free and should make up at least half of one's daily grain intake.
Step-by-step explanation:
Six grains that are gluten-free and can be included in the diet of someone with celiac disease or gluten sensitivity include Rice (especially brown rice, which is a whole grain), Oats (ensure they are certified gluten-free as oats can be cross-contaminated with gluten), Corn (including cornmeal and popcorn), Quinoa, Buckwheat (which, despite its name, is not related to wheat and is gluten-free), Millet. When incorporating grains into your diet, it is important to make healthy choices. Whole grains should make up at least half of your daily grain intake. Always read food labels carefully to ensure that the grains are indeed gluten-free and that they do not contain any traces of gluten, which can be harmful to those with celiac disease or gluten sensitivity.
