Dairy Intolerance (Lactose, Casein, and Whey)

February 15, 2018

Having a food intolerance is not fun. It can cause abdominal pain, discomfort, and nausea. It also causes embarrassing symptoms like flatulence and diarrhea. Other symptoms linked to food intolerances include muscle or joint pain, headaches, exhaustion, and even skin symptoms like rashes and eczema.

 

Dairy is just one of those foods that many people seem to be intolerant of.  I have a ton of experience with this specific intolerance and allergy.  Let’s talk about the main components of milk that people react to: lactose, casein, and whey.

 

 

Milk sugar (lactose) intolerance

 

It’s estimated that up to 75% of adults are lactose intolerant. Lactose is the carbohydrate “milk sugar” naturally found in most dairy products. Lactose intolerance is so common you can buy lactose-free milk in your regular grocery store. Lactose-free products are treated with the enzyme “lactase” that breaks the lactose down before you ingest it. It’s this lactase enzyme that is lacking in most people who are lactose intolerant.

 

The lactase enzyme is naturally released from your intestine as one of your digestive enzymes. It breaks down the lactose sugar in the gut. When someone doesn't have enough lactase, the lactose doesn't get broken down the way it should.  Undigested lactose ends up being food for the resident gut microbes. As they ferment the lactose, they create gases that cause bloating, flatulence, pain, and sometimes diarrhea.

 

Lactose is in dairy but is in lower amounts in fermented dairy (e.g. cheese & yogurt) and butter. Steering clear of lactose isn't that easy as it is added to other foods like baked goods, soups, and sauces. And if you're taking any medications or supplements, check to see if it's in there too, as lactose is a common ingredient in them.

 

If you have symptoms of lactose intolerance, keep an eye on food, medication, and supplement labels.

 

Fun Fact: Raw milk already contains the enzyme lactase to already start breaking down lactose.  I was fortunate enough to try raw milk a few years ago and had absolutely no reaction to lactose.  Unfortunately it is illegal to buy and sell raw milk in the province of Alberta, and in many other provinces in Canada.

 

Milk protein (casein & whey) allergy

 

Milk is a known, and common, food allergen. In Canada, it is considered a “priority allergen” and must be declared on food labels.

 

So, what are the allergens in milk? You've heard of "curds and whey?" Well, these are the two main proteins in milk. The solid bits are the curds (made of casein), and the liquid is the dissolved whey.

 

Unlike lactose intolerance, casein and whey can cause an actual immune response. It’s an allergy. And this immune response can cause inflammation. In fact, we don’t know how many people have these milk allergies, but most estimates put it far below that of lactose intolerance.

 

Like lactose, these allergenic milk proteins can be found in other products too. They're not just in dairy but are often in protein powders as well (Have you heard of "whey" protein powders?).

 

Some of the symptoms of milk protein allergy differ from that of lactose intolerance; things like nasal congestion and mucus (phlegm) are more common here. And casein seems to be linked with belly fat.

 

Interestingly, people who have gluten intolerance are often allergic to milk proteins like whey and casein as well. These can go hand-in-hand.

 

Like lactose intolerance, if you're allergic to casein and whey keep an eye on labels so you can avoid these.

 

I found out my own allergy response to casein and whey when I started to develop inflammation in my stomach which pushed through my esophagus.  I could barely drink my magnificent protein shake without feeling full, all the while I kept gaining additional weight.  I found out that I did indeed have an allergy to whey which was causing the inflammation and creating additional stomach problems for me.  I quickly cut that out and it took about a month and that inflammation went down dramatically.  

 

Conclusion

 

If you get gassy, bloated, or diarrhea after eating dairy, you may have a lactose intolerance. If you often get a stuffy nose and mucus, then you may be allergic to casein and/or whey. If you are concerned that you may have food allergies, send me a message and we can get you started on a food allergy testing kit (IGg) today.

 

While dairy may be an entire food group, it is not an essential nutrient. All the nutrients in dairy are available in other foods. If you experience these symptoms, you can try removing dairy from your diet. You may find improved digestion and fewer gut issues. Or you may find improved nasal congestion, or even less belly fat.
