Be careful with products from South Africa. We are from South Africa , now living in Canada and I went to a South African store to buy some cereal. The packaging said Gluten Free but when we read the ingredients it says that there is barley malt - I contacted the company and they told me that the level of Gluten is low enough that they can state that it is Gluten Free..
"This is what they said
Several countries have implemented strict regulations for products carrying gluten free claims, and South Africa is no different. The CODEX Alimentarius Standard and the Draft South African labelling legislation require that the level of gluten in the final product 20 parts per million (20 ppm) of gluten in a product to be eligible to carry a gluten free claim. It has been reported that patients with celiac disease can consume these levels of gluten without any adverse effects.
We have our products tested annually by FACTSSA (Food & Allergy Consulting & Testing Services), who could confirm that the following Kellogg products qualify for a gluten free claim, as they contain exceptionally low levels of gluten "
Our 10year old son tested positive with blood work - we took him off Gluten that minute - I noticed an improvement within a week - now he has been Gluten Free for 2 months and he is a completely different child. We elected to not have the biopsy since his blood results were so high ( over 200 ) and when we saw the GI he said that he would refer us to the celiac clinic even if we decided not to do the biopsy. My son knows that he is feeling better and so he is prepared to eliminate the Gluten even without the "gold standard" diagnosis.
I cannot believe the difference in my son - his taste buds seemed to have opened up too and he is now eager to try new foods where before he would not stray for his very limited diet - I realize now that this was probably because he associated food with not feeling well but was doing that without even been aware that he was!
You should see a difference in the behaviour / energy level quite away but I would say that the bowel takes longer to heal and that would be about 3 weeks before there was a consistent improvement.
My Son is 10 and has just been diagnosed - based on the high readings from his blood test, we decided to not have the biopsy - I have not heard of any results where the blood tests are so high and the biopsy comes back negative. We did see the peadiatric GI who has said that the blood tests are so good now and that even if we did not have the biopsy - he would enrol us in the celiac patient program.
