As far as I am aware, yes. Maybe not with a 100% success rate, but yes. I am white as snow and when I went vegan I developed a lactose intolerance (every once in a blue moon I’ll accidentally grab some milk chocolate or something without realising.) While there’s probably some genetics at play, western cultures have a much higher focus on milk, so you are much more likely to just drink/consume milk with some regularity throughout your life, from childhood, so you just never lose those… well, I don’t know, enzymes, I think? Every mammal starts out with a lactose tolerance, after all.
