Pizza, unsurprisingly, tops the list. The science?
Cheese contains a protein called casein. During digestion, casein releases opiates called casomorphins.
Pizza Hut, Little Caesars, Dominoes and Papa John's perfected the pie fat fixed and festooned in frightful piles of casein encrusted Mozzarella, Provolone, and Cheddar.
Bon Appetite!
