Thank you for you efforts to make things easier for coeliacs. However, your leaflet has a basic error. Under Gluten-free alternatives you have got the word 'for' instead of with so that you are in effect telling people to eat wheat instead of rice etc
eg"Substitute wheat flour for potato". This error is in all of these sentences except for your Sainsbury's own brand cereals.
It will be interesting to see if they change this - anyone that spots a revised leaflet let me know!
