What Does My Child Need to Avoid on the GFCF Diet?
First, what are gluten and casein? It is easier to identify foods and products that contain these proteins if you understand what they are!
Gluten is a special protein that is found in wheat, rye, barley, bulgur, Kamut, spelt, and foods made from those grains. Gluten gives breads and grains their texture. It is often used as a filler in meat products like hot dogs and lunchmeat. Gluten is found in food starches, semolina, couscous, malt, some vinegars, soy sauce, flavorings, artificial colors, and hydrolyzed vegetable proteins.
Casein is a protein found in milk and foods containing milk. These include cheese, butter, yogurt, ice cream, whey, and many brands of margarine. It also may be added to non-milk products such as soy cheese and hot dogs in the form of caseinate.
Are all “soy” or “dairy-free” products gluten- and casein-free?
No! This cookbook uses a lot of soy products (i.e., soy cheese and soy milk) but it can be hard to find truly casein-free soy dairy products. Many of them contain caseinate, so it is imperative to read labels carefully! Often, these items can be special ordered online, or your local grocery store may be able to order a supply to keep in stock. There are online resources that make it easier to locate GFCF foods.

Hidden Sources of Gluten and Casein
Certain foods are easy to identify as safe or unsafe. Others might be a little trickier. These items might also contain gluten or casein and it may require a little more research to determine if the food is safe.
Please read the labels of these items carefully to eliminate those that contain gluten and casein from your family's lifestyle. It might be necessary to call the phone number on the back of the product and ask the manufacturer the sources of some of these ingredients. If they are not from a gluten or casein source then they are safe to consume.
