I've just finished reading Gluten Attack : Is gluten washing war on our health by Professor David Sanders.
it's a refreshingly honest book written by a professor of medicine whose specialist interest is coeliac disease.
he unpicks lots of medical issues like IBS, gluten sensitivities, allergies and intolerances' and describes how seemingly unrelated diseases and issues might be linked.
Thoroughly recommend it to anyone interested and everyone searching for answers.
