We've recently had contaminated eggs from the EU and there was the fuss over chlorinated chicken from the US when supermarkets have been selling bags of mixed salad that can have 19 times more chlorine in it than in a swimming pool and when challenged suppliers said their customers wanted a disinfected product.
Going back to Dr James Cave in the BMJ recording Suzy posted he rightly said it was a faff it was getting food on prescription compared to just buying it in the shops and Gemma the little girls mum who made some very good points says that she has to drive to a supermarket and cannot guarantee being able to buy gf bread. Now with a little forward planning just needs to keep her freezer well stocked so this need not be an issue.
I drove to Scotland last month and called in at a Tesco's in Stirling in the early evening and bought a loaf of Genius 3 seeded bread made with naturally gf flours and linseed and some Tesco's own brand white rolls with quinoa flour. Now I'd rather eat these than codex wheat that has to be fortified as its so processed.
James Cave is expressing his honest opinion as a Dr and some people agree with him and some don't and thats life.
And just maybe if coeliac didn't get food on prescription then there would be more opportunities for individual gf bakeries, as the free from trade is much more profitable than ordinary discounted supermarket food.
In my opinion you want to think about how to deal with not getting food on prescription.
