Addicted to Cheese? Here’s Why
They tried to make me to go cheese rehab, I said no, no, no! While many of us may joke about being "addicted" to cheese, the truth is...well, you might be. As early as the 1980s, scientists have been aware that cheese contains trace amounts of morphine -- it's present in cow (and human) milk.
Researchers also discovered the protein casein, which breaks into casomorphins when it is digested and also produces opiate effects. In cheese, casein is concentrated, and so is the level of casomorphins, so the pleasurable effect is greater. Neal Barnard, MD said, “Since cheese is processed to express out all the liquid, it’s an incredibly concentrated source of casomorphins—you might call it dairy crack.”
