Hi Dawn,
Dairy makes me worse. Chicken soup for some reason gives me diarreah. What about gluten free bread like Kinikkinikk, something like that, they make rice bread and this might help.
Can he down brown rice, green bananas? That's a new thing, sort of, was on Dr. Oz called Resistant starches. Eat rice room tempature. It's been on this forum for a while now if you search.
I hope he feels better soon!
Bananagirl suggest Black Strap Molasass that's good and has good iron in it.
