Is Cow Milk Gluten-Free?

Yes, cow milk is gluten-free. Whether you choose whole, low-fat or lactose-free cow’s milk, it is gluten-free. Gluten is a protein found in certain grains, so foods from other food groups are typically gluten-free, as long as no gluten-containing ingredients are added. Below, we answer common questions about milk, dairy foods, and gluten.

Is There Gluten In Dairy Foods?

While it is naturally gluten-free, milk can have gluten if additives or flavorings are included in the final product. The same goes for other dairy foods, which can contain gluten if added ingredients or cross-contamination occurs during manufacturing. Examples include:

• Flavored milk or milk powders with thickeners or malt
• Certain cheese spreads or processed frozen desserts
• Additives like modified food starch or “natural flavors”

Always check ingredient labels or contact the manufacturer if you’re unsure. Products certified gluten-free provide additional assurance for those with celiac disease or severe gluten sensitivity.

Does Whey Contain Gluten?

Whey protein, a byproduct of milk, is naturally gluten-free. Most whey-based products, like protein powders or dairy supplements, remain safe as long as no gluten-containing ingredients are added during processing. Always check labels for flavorings or additives if you have celiac disease or high gluten sensitivity.

Which Foods Contain Gluten?

Gluten is a protein naturally found in wheat (durum, spelt, farro, etc.), rye, barley and combinations of these grains. So, foods made from these grains such as pasta, bread, cereals, and others, will contain gluten. It is possible for other grains and foods to have traces of gluten if they are made or packaged in the same place as the grains that do contain gluten.

Should I Be Concerned About Gluten?

You should only be concerned about gluten if you have a gluten sensitivity or celiac disease, an auto-immune disease that causes people not to be able to digest and break down gluten in their bodies. Celiac disease affects an estimated one in 100 people worldwide. 

Here’s another thing to keep in mind: Since some foods, like vegetables, fruits and others are naturally gluten-free, they may not always be labeled “gluten-free.” But, by using some of the best practices above, you can feel confident that your milk and most other dairy foods are indeed gluten-free.
