Now after many eons of milk consumption all of a sudden in the last 60-70 years AFTER the intoduction of pasturization some people have become lactose intolerent. Does the mainstream blame pasturization for this?
Just because a disease was not understood or characterized doesn't mean it didn't exist. They have actually found that adults gradually develop lactose intolerence by their lack of dairy consumption. All you need to do to avoid the gastric distress is to eat yogurt with Lactobacillus acidophilus daily.
