Can someone please explain what the term "Strict Gluten Free Diet means".
If it means you comply with the recognised gluten free diet then you are ingesting small amounts of gluten. I am personally "Free of Gluten" (FOG). Even the smallest amount of gluten from derivatives has a very laxative effect on me as well as the other problems it causes.
Gluten Free is a term used to indicate that the finished product may contain up to 20ppm of gluten in a kilo of finished product, this maybe considered very low but there are Coeliac's who do suffer from this small amount.
To state you have an allergy to gluten then you need to be assessed by an allergy consultant, Oral, Topical & Respiratory. But it is known that some Coeliac's react to airbourne wheat.
