The ability for adults in some populations to digest animal milk was a useful adaptation to add caloric options to the diet.

I don't know man. Cheese, yogurt, kefir, butter, ice cream are tasty in moderation. Cheese wheels last forever if made and stored properly.

[link to www.atlasobscura.com (secure)] That is a link about people who make cheese wheels so people have something to eat at the funeral.

You could always try fermented mare's milk or goat milk if cow milk isn't your thing.

That said I respect someone elses decision not to consume milk. You have to look at quality and the sugar and fat content mean adults should maybe consume in moderation. Vegan substitutes don't do it for me but you and I are free to make our own choices.
