Hidden Sources of Milk & Dairy

Hidden Sources of Dairy by The Allergy Chef

When you’re first diagnosed with a dairy/milk allergy, it can be completely overwhelming. Dairy can be found in just about every corner of the grocery store. Not only are there obvious sources, but dairy can hide under different names. We’re going to break it down for you so you can spot dairy in the wild and avoid it. If you have a severe dairy allergy, you’ll need to assess if you’re able to tolerate food made on shared equipment with dairy, as well as a shared facility with dairy.

Dairy Definition

When it comes to dairy, you may hear terms such as:

  • Lactose/Lactose Free
  • Whey
  • Cow’s Milk Protein Allergy (CMPA)
  • Casein
  • Ghee
  • Milk Fat
  • Milk Solids
  • Milk Powder

The conventional definition of dairy (where food allergies are concerned) is: food made from or containing dairy. The dairy can come from Buffalo, Camel, Cow, Goat, and Sheep.

Different Parts of Milk

Casein: The main protein present in milk and cheese.

Ghee: Clarified butter made from the milk of a buffalo or cow. Some feel this is “dairy free” since it’s the fat content and the protein is removed.

Lactose: The sugar present in milk.

Whey: The watery part of milk that remains after the formation of curds.

How to Check Labels For Dairy

Finding milk and dairy on a food label is mostly straight forward. Pick up any packaged food item with a printed ingredient list and read it over. In some countries, if a major allergen is included it must either printed in bold or called out at the end (contains milk).

As you read over the label, look for the milk terms I shared above. You’re looking for milk, powdered milk, casein, ghee, lactose, whey, and whey isolate. These are the terms you’ll most likely see.

No matter which country you live in, even if it’s supposed to be called out on the label, make an effort to read over labels twice. It’s very easy for the eye to skip over ingredients, and it doesn’t help that the print is so tiny.

How to Find Hidden Dairy on Food Labels

All over the world, dairy is considered a major allergen, which should make identifying it on a food label easier. However, this is not always the case. Some labels may say “may contain traces of dairy” or “contains milk” or “made on shared equipment with milk”, etc. You may find our tips on Reading Food Labels helpful.

Before consuming products, it’s important that you call to learn more about the sourcing of raw materials, how the food is processed, stored, and packaged. Each step in manufacturing can expose the product to something you’re allergic to, including dairy.

Some companies are putting their best food forward by creating pages on their website that list all of these details for each product. A great example of this is Simple Mills. Others aren’t great at listing their protocols and you will need to get comfortable calling companies.

The thing about hidden dairy is that it won’t be on the label. For example, cream (milk) can be used as a defomer in maple syrup production. IT’S NOT ON THE LABEL. It’s a processing aide. This is really what finding hidden dairy is all about. It’s understanding HOW something was made, the equipment, and much more.

You need to go to this extent of investigation if you (or the person you manage) cannot tolerate trace amounts of dairy. We’ve found that about 30% of people with food allergies fall into this group.

If you want to learn more about what is required for companies in terms of labeling for food allergies, I recommend familiarizing yourself with the FDA guidelines. Just know going in, there are loopholes.

Avoid products made in shared facilities and/or on shared equipment with dairy. There have been several recalls as of late for undisclosed dairy. Honestly, this terrifies me the most, which is why in our home, shared facility food is a no-go for our kid with a dairy allergy. Many of the recalled products are probably things you’ve never heard of, but a couple were from brands that specifically market to those who are dairy free.

Our Safe Product Guides and Lists contain hundreds of products, all of which are made on free-from equipment. We’ve done the work and made over 1,000 calls to find out information from the manufactures to compile our lists.
