[Margaret Pilkington]

This story is a non starter. People who have coeliac disease who require these prescriptions rarely eat junk food.....because most junk food is not gluten free.
An occasional treat of a donut, a pizza or a biscuit is something which really IS a treat for them because they cannot eat foods which contain gluten.

I know that there are some gluten free products in supermarkets, but these are usually at prices far higher than normal non gluten free products.

There is much trash written about the obesity crisis..Lazy journalism most of it.
Coeliac sufferers are rarely(if ever)obese....their diet is much healthier because it contains no wheat.....most processed foods contains wheat or wheat derivatives( maltodextrin,complex starch, thickeners )
Being coeliac or even gluten intolerant is no pleasure at all.
