“these peoples remained intolerant to lactose (natural sugar in the milk of mammals) for...4,000 years after the onset of cheese-making among Central European Neolithic farmers.”
Are they saying that lactose intolerant people continued to make cheese for 4,000 years after discovering that they couldn’t eat it?
I am reading a book on the history of British food, and back in medieval days, drinking milk from animals was not done — it was reserved for cheesemaking. Almond milk was common — which I had thought was a new invention.
If at first you don't succeed...
It's a triumph of the human spirit, I tell you.
