>Few claim to be lactose tolerant in adulthood, but how lactose tolerant are they? Really it is not a physiological tolerance, but a mental one, an acceptance that odd rashes and a digestive tract that works less than perfectly is normal, when it isn't. This threw me off. I don't know anyone ethnically local to my area that is lactose intolerant except for one grandma and it indeed becomes more common with age. Nobody else has odd rashes or digestive tract issues linked to it. We know perfectly well how some populations have adjusted to being capable of properly digesting it so your claims seem wild. https://en.wikipedia.org/wiki/Lactase#Genetic_expression_and_regulation https://en.wikipedia.org/wiki/Lactase#Genetic_expression_and...
