DonFerrari said: The trends seem to always be changing and going back to the same place. Perhaps you don't know that the population that is most lactose intolerant are the Asians (a lot among japanese) and the main explanation is that for the previous several gen they weren't drinking cow milk and dairies so their system got unused to it so nowadays they are the most part of the intolerant population. What you are pointing at seems more like allergies, where some types the person will only trigger at a certain age or due to continuous exposition. Also everyone reacts different so it may not even be some type of abuse. |
You say Asians got un-used to eating dairy. It's that they rarely ate dairy in the first place, not that they at some point got used to not eating it. Humans only started eating dairy about 8-10K years ago, a blink of an eye evolutionarily.
And your body can get used to almost anything. Someone from a long line of heavy drinkers might have a higher tolerance towards alcohol. But that doesn't mean being a heavy drinker is good for you.
