I am not 100% sure but both items I ate were supposed to be gluten free - and because of the mouth sores almost immediately I looked up the straws - it did not state any brands .
Thanks tho for the info!
We are travelling at present and I had a drink from a fast food restaurant- with a ‘paper’ straw . Within the hour I had cankors in my mouth and a painful tongue!
After investigating I found that the food I ate and drank was gluten free - but the straw was not! Beware all celiacs !
