Actually, that’s not quite true. Almost all humans produce lactase (the enzyme required to digest milk) at birth in order to digest their mother’s milk, which is about 9% lactose. In most populations, as the child is weaned, their need to produce lactase goes away as they consume less and less milk, so they ‘become’ lactose intolerant as they become adults. However, with the domestication of sheep, goats, and other dairy animals around the mediterranean, the people who raised them consumed milk their entire lives, so their lactase production never stopped. Eventually, a genetic quirk that caused lactase production through adulthood somehow came about and quickly became dominant in the populations that consumed lots of dairy products, which is why Europeans have such a low rate of lactose intolerance, and most of them who are lactose intolerant suddenly became so at some point in their life. The lactose intolerance in Asians didn’t happen because of the traditional diet, they just never really became lactose tolerant in the first place because of their traditional diet.

So, you’ve got it partially right. In any case, I’m lactose intolerant so I LOVE soy products.
