Parmigiano-Reggiano is the most protein dense food on earth at 34% protein per 100g. It has more protein than chicken and beef. It is one of the most efficient sources of bioavailable nutrition humans have ever created. Fermenting it for up to 1.5 years means -easier digestion -faster absorption -lactose free/zero carb It's an elite source of calcium (the best in an animal-based diet), loaded with vitamin K2, peptides that support gut health and glutamate. It's truly one of the greatest things to ever come out of Italy. One more thing about Parm. If you're like me, too much cheese can make you gain weight. The problem, I believe is because most cheese is a combo of fat, protein and carbs. Fat by itself is not obesogenic but when paired up with carbs causes gains. The good thing about parm is it's zero carb because there's no lactose, so in theory, no weight gain.
