WTF Is Casein?!

Posted August 8, 2013 by Whitney Calk

If you’re like me, you’ve mayyybe accidentally returned from the grocery store on occasion with a couple of nonvegan items. Skimming the ingredients for “milk” and the packaging for “nondairy” seems like it should be enough, but the truth is that sometimes animal-derived ingredients can be overlooked. Case in point: casein.


Casein is the main protein in milk, and oddly enough, it’s often found in food items marked “nondairy.”

In the dairy industry, cows are repeatedly impregnated and have their babies stolen from them within days of giving birth. Once their bodies give out, these intelligent, social animals are sent to their deaths in slaughterhouses. </3

Since you’re awesome and have hopefully already made the compassionate decision to ditch dairy, be sure to avoid accidentally supporting this industry by always checking ingredients closely!

    Casein is a pain in the ass. I once bought almond cheese only to realize when I got home that it was full of casein. Otherwise, it would be vegan. What is casein for anyway?

      Casein is used in dairy-free cheeses to make it have the same melting effect as dairy cheeses. Ridic when you could just buy Daiya, Teese, or other vegan cheeses that totes melt, too.

    I am 13 years old and joined the street team June 2015. I am a vegetarian. I have a passion for working to help save animals. I love my family and my 2 pugs, Daisy and Diesel. I plan to work for Peta or Mercy For Animals someday because they helped me become a vegetarian and begin a whole new life of having common sense towards all animals.
