Yes, whey is gluten-free since the whey protein itself is gluten-free. On the container, whey may be labeled as "whey concentrate," "whey isolate," or "whey hydrolysate." All of these whey protein products are gluten-free and suitable for celiac patients. Whey contains important nutrients such as iron, calcium, and vitamin D. Because people with celiac disease cannot digest gluten, it would not be absorbed into their bodies when they eat foods containing wheat proteins, including bread, pasta, and beer. Instead, it goes straight through them without being digested. The only thing that happens to gluten when it comes in contact with water is that some of its strength is lost. This means that if you pour liquid containing gluten onto wet ground, most of the gluten will disappear. Only small amounts of gluten remain in milk, because casein, another protein found in milk, binds to gluten and prevents it from disappearing. People who know you have celiac disease may ask why you would want to drink milk when you can't eat gluten. The reason is that drinking milk helps prevent osteoporosis by providing high levels of calcium and phosphorus which help build strong bones. This is especially important since people with celiac disease are at risk for developing osteoporosis due to poor bone density resulting from eating no gluten for many years.
