If you're more of a fromagerie fan than a chocolate addict, I have good news for you (or bad, depending on the severity of your affinity). Researchers from the University of Michigan have found that cheese contains a chemical that's also present in drugs. Well, actually a lot of processed food is associated with addictive-like eating behavior, but cheese in particular contains casein, a protein commonly found in mammal milk. Casein provides your body with amino acids, carbohydrates, calcium, and phosphorus, and it can also trigger your brain's opioid receptors and deliver feelings of euphoria similar to those delivered by cannabis.
Although casein in milk provides only a tiny dose of the drug-like effects, to make a pound of cheese you need about 10lbs of milk. The casein separates from liquids and coagulates solid milk fats, resulting in a higher concentration of it in cheese and the potential for addictive eating. So the next time you exclaim, "Man, I can't get enough of this cheese!", you could actually be talking about both the hybrid strain Cheese and the delicious cheese and charcuterie spread in front of you, but either way, you're probably experiencing similar feelings of happiness and euphoria.
