Question

I heard 2/3 of the world is lactose intolerant, is this new? Or is there another reason

In: 0

Answer 1

Because during WW2 they upped dairy productuon to send lots of milk powder out to troops. After the war, they had a massive surplus of milk suppliers, so they had to convince the public they needed lots of milk every day.

There is more accessible calcium in broccoli than there is in milk.
