Hi Chris you know how sometimes you give a
great answer then realise it's not answering the question that was asked.
Perhaps this can help gluten is relatively hard for your body to break down.
So logically
gluten free food should be easier for your body to break down because there is no gluten it should enter your blood stream faster. Your body breaks down cabs faster than any other food type so
gluten free carbs should break down even faster still.
This could be why you are experiencing the bg spikes you mentioned.
Same advice though stop eating them.
