How old is he?
You can make fruit smoothies: frozen berries, enriched rice milk, peaches
have you tried different kinds of juices? there's cherry juice, grape juice, oj, etc. If you've only tried apple juice, maybe he is just sensitive to that.
You could also have him drink chicken broth (the good kind, simmered for 24 hours). It's full of nutrients. I love sipping it all winter long. Or water and make sure that he gets enough nutrients otherwise. My DD1 drinks water and smoothies for drinks.
Are these IgE allergies? Just curious, since if he was only tested for allergies, then it's possible that he has intolerances too (like the tummyache from juice). So you may want to keep a food journal to see if anything else comes up. Are you avoiding just wheat or all gluten?
My kids like baked salmon with sauteed spinach, chicken soup, mini meatball soup (with ground turkey meatballs, carrots, and celery), roast chicken with gravy from the drippings (thickened with sweet potato starch instead of wheat flour), pot roast, buckwheat pancakes, creamy buckwheat cereal (hot), Cream of rice cereal...
