What type of food is generally avoided by those with coeliac disease?

Individuals with coeliac disease must avoid gluten-containing foods because gluten triggers an autoimmune response that damages the lining of the small intestine. Gluten is a protein found in wheat, barley, and rye, which are common ingredients in many foods, including bread, pasta, and baked goods. Consuming gluten can lead to symptoms such as abdominal pain, bloating, diarrhea, and long-term health issues, making strict adherence to a gluten-free diet essential for managing the condition.

In contrast, the other options mentioned—dairy products, fruits and vegetables, and legumes—are not inherently harmful to people with coeliac disease and can typically be included in their diet, depending on individual tolerance and any additional dietary restrictions.
