You may need to check if he is gluten intolerant, wheat gluten intolerant or coeliac. I am G/I & there are thing on the coeliac list that I can't have. It's in breakfast cereals & other things I think it's maltodextroze. I am full blown G/I whereas OH is wheat gluten intolerant. It does get complicated, we find breakfast is the worst meal of the day for us. Basic main meals are easy I use Kallo G/F stock cubes & cornflour to make gravy. If you think I can of further help feel free to PM me.
HTH,
