In the first of a three part health series that will go on to include a look at food and environmental allergies, The Weekend investigates coeliac disease. Ceoliac disease affects approximately one in every 100 people in New Zealand, with many going undiagnosed. It's not a food allergy. Rather it's a permanent, autoimmune disorder caused by intolerance to gluten found in wheat, barley, oats and rye. We hear from Helen Carey: mother of 12 year old daughter and coeliac Janine, Coeliac New Zealand President Terry Hoskins, and Neville Green from Gluten Free Made Easy.
