4 Reasons You Should Avoid Casein

Why You Should Avoid Casein

Casein, the hard to digest protein found in milk, has the potential to wreak havoc on your health. Here are the top four reasons you need to avoid it at all costs.

Casein makes up 80% of the protein found in milk, it’s what gives it the white color. Whey protein isolate, the protein MariGold uses (which our body digests and absorbs quickly), makes up the other 20%. Whey protein concentrate contains both whey isolate and casein.  What makes casein so bad is how our body reacts to it.

1. Casein Causes an Addictive Response

A component in casein known as casomophins, act like opiates as they break down. As casein slowly digests, the casomorphins attach to opiate receptors in the brain and can actually cause you to become addicted to dairy products.

Next time you hear someone say they’re “addicted to cheese,” they’re speaking the truth! The response to casomorphins has been compared to heroin in terms of their ability to cause addiction.

2. It Puts Strain on the Digestive System

Because casein breaks down so slowly, it places a great deal of strain on the digestive system. While many people think their negative reaction to dairy products is due to lactose-intolerance, it’s very likely that it might actually be the casein. The digestion difficulties could be from your gut lacking the enzymes necessary to digest this type of protein.

Symptoms of this issue can gas, nausea, bloating, and stomach pain.

3. It Can Cause Respiratory Issues

Did you know that casein is used to make a strong type of glue for wood bonding? Because of its thick and coarse properties, woodworkers use it for its strength and long lasting effects. Unfortunately for us, it’s great at forming mucus. The human respiratory system can become clogged due to this protein. If you’re noticing wheezing, coughing, congestion, a runny nose, or itchy eyes, this could be from the casein.

4. It Can Induce the Same Reactions as a Gluten Intolerance

Casein is very similar in structure to gluten and often times can cause adverse cross reactions in people suffering from a gluten intolerance. Studies have shown that about 50% of gluten sensitive patients have a sensitivity to casein as well. If your symptoms have not improved after going gluten-free, it’s a good idea to try eliminating dairy as well. A diet like Paleo might be best for your digestive system.

    Interesting article. I didn’t know about the addictive nature of casein. It has gradually dawned on me over the years that the slight digestive upset that I get from the whey concentrate powder in my smoothies may be from the pasteurized casein. I’ll keep using it, along with digestive enzymes, until I run out, but then I’ll start paying the considerable extra for whey isolate.
    While I’ve given up most dairy products, I enjoy a quart of whole raw grass-fed milk 1-3 times a year. With every creamy swallow, I can feel my body going, “Yah mon, me like dat; gimme more”.
    Whether I chug it all on the spot or ration it out over a week, I have yet to be able to identify any excess mucus production, digestive upset, or any other negative reaction as a result. Given that raw milk has gotten a raw deal by being identified as potentially dangerous, the amount of raw milk available on the market is infinitesimal and most of us haven’t ever had any.
    I am intuitively sure that pasteurization, involving high temperatures, and homogenization, involving high pressure, degrade and denature milk and at least magnify reactions due to casein, if not cause them per se. Pasteurization involves either 145 degrees for 30 minutes or 162 degrees for 15 seconds. Shockingly, ultra-pasteurization involves 275 degrees for 2-5 seconds. Remember, water boils at 212 degrees. That process kills healthy bacteria and ruins the taste.

      Coming from a strong, powerful woman like you, Judy, this means a lot!
      Thank you for teaching me the value of focus. ❤️

  2. Good article! Thanks for sharing. I’ve been drinking casein-free A2 milk which has definitely made a difference.

  3. Is your milk A1 or A2 and are your cows grass fed AND GRASS FINISHED! ARE THEY FED EITHER CORN OR SOY?

    The answers will determine if I reorder these products.

    Thank you,

      Roberta, thanks for reaching out.
      A1 and A2 differentiation is in the casein. Our product is made from whey isolate which does not contain casein.
      “Grass-finished” is not a term that relates to dairy cows. That term applies to cattle before they are slaughtered.
      As far as whether our whey comes from cows that fed corn or soy, our supplier indicates that our whey comes from milk from cows that are grass fed, and that the whey is non GMO and grain free.
