Who does gluten affect?

For people who are diagnosed with coeliac disease, eating gluten triggers an immune reaction which leads to damage of the lining of the small intestine, preventing the normal absorption of nutrients from food.

There has been ongoing debate regarding the suitability of oats in a gluten-free diet. Oats contain avenin, a protein similar to gluten. However, research has shown that most people with coeliac disease can safely include gluten-free uncontaminated oats as part of their gluten-free diet.

As well as coeliac disease, gluten is associated with other conditions, such as non-coeliac gluten sensitivity and IBS.
