Cooper journeys through doctor visits, hospital stays, blood tests, an MRI and an endoscopy to find that he has Celiac Disease which is a gluten intolerance. He learns about villi, intestines, antibodies and more. After his initial disappointment at giving up his favorite foods, he finds there are actually ways to make pizza, muffins, cookies, pasta, and even bagels gluten free. He also discovers that there are others in his family who can’t eat gluten – even a very unexpected someone – Buddy, his golden retriever!
