Experts have used magnetic resonance imaging (MRI) to better understand the impact a gluten free diet has on people with celiac disease, which could be the first step towards finding new ways of treating the condition. Celiac disease is a chronic condition affecting around one person in every 100 in the general population. When people with celiac disease eat gluten, which is found in pasta and bread, their immune system produces an abnormal reaction that inflames and damages the gut tissue and causes symptoms such as abdominal pain and bloating.
