  • AHA! Mystery solved!

    October 20, 2009

  • "So many people have complained to us about how hard it was to give up cheese that we almost felt like we needed to set up some kind of support group in the basement of an area church where we served burnt coffee (with soy creamer) and let people talk about how many days cheese-clean they’ve been. Frankly, the whole thing was perplexing for us until we read up on casomorphins, or opioid chemicals that are present in cow’s milk (and by extension, very much present in cheese). Evolutionarily, these peptides probably had the function of creating a positive association between the calf and its mother and her milk. Now, however, humans consume more cow’s milk than calves do, and – improbable though it sounds – those who consume large amounts of dairy products are probably mildly addicted to them. It isn’t like you’re going to get the DTs or have seizures if you give up cheese, but certainly, these opiate effects can help to explain the more than mild cravings that lots of people have."
