The website Tacanow.org provides a list of gluten-free and casein-free foods, according to Talk About Curing Autism. Food labels can change, so a food on the list may not always be gluten- and casein-free. It is important to double check labels before buying these foods.
Some baby foods that are gluten- and casein-free include Elecare formula, Neocate formula, Duocal medical food and Beech Nut Rice Cereal for Baby Stage 1, notes Talk About Curing Autism. Elecare formula should be used under a doctor's supervision and is used for oral or tube feeding. The Neocate formula is good for children with food sensitivities and allergies. Duocal is a powdered medical food that provides fat and carbohydrate for increased caloric intake for children over the age of 1. The Beech Nut Rice Cereal for Baby Stage 1 is great in muffin recipes.
Some baking mixes for cookies that are gluten- and casein-free include Cherrybrook Kitchen Chocolate Chip Cookie Mix and Kirkman Labs Cookie Base, states Talk About Curing Autism. The Cherrybrook Kitchen Chocolate Chip Cookie Mix product has a banner across the box that states it is gluten-free, as there are nongluten-free versions as well. The Kirkman Labs Cookie Base package has instructions for sugar, lemon, chocolate chip, peanut butter and oatmeal-type cookies on the box.
