I heard 2/3 of the world is lactose intolerant, is this new? Or is there another reason
In: 0
Most of the world being lactose intolerant(as adults) isn’t new at all. If anything, it’s more of the norm than the exception. IIRC the gene that codes for being able to handle lactose as an adult is a mutation, the *default* is lactose intolerance happening as an adult.
It’s theorized it started somewhere in the middle east, but the gene didn’t make it over the Himalayas so most of East Asia is lactose intolerant as adults. There are also theories that the gene wasn’t really that useful in areas that didn’t support dairy farming well.
Why is it important?
Milk itself, isn’t
The nutrients in it are.
Calcium, potassium, vitamin D, proteins, etc can all be had from other forms of diet.
It’s a little bit of marketing, and a little bit of “Well a bunch of nutrients that are important are in one drink.”
You can get proteins from beans, vitamin D from fish and the sun, calcium from kale. Milk just has a blend of all of them.
