I agree with gottaski - you should get levels tested for Vit A, Vit D, B Vit and Iron. Calcium too if possible. Even if he's not deficient, I don't think taking a Carlson's capsule would be harmful. You can look up reputable maximum supplementation levels of specific vitamins via sites like National Institute of Health (US) or Mayo Clinic.
If he's not dairy intolerant, a Boost drink daily is a good idea.
Regarding the recipes, the carrot cake, cornbread and enchiladas aren't really "mine" - I make the Gluten Free Goddess's version found here: http://glutenfreegod...arrot-cake.html And the cornbread is hers too but I make it without the green chilis: http://glutenfreegod...een-chiles.html
Chicken enchilada recepie: http://glutenfreegod...enchiladas.html (Sorry to call them "mine" but she has great recepies that have become family legends. And her dark chocolate brownies are to die for - even for gluten eaters.)
I make chili from an old Betty Crocker cookbook and I'll post that later.
What kind of curry does your family like? Spicy? Authentic? With cream or coconut milk? I have several curry recepies.
Also, I'd like to put in a plug for Stephanie O'Dea's "A year of slow cooking" blog - she cooks only gluten free and these are great family meals. http://crockpot365.b...ili-recipe.html
Good luck and let us know how it goes.
