Interesting post for me in general (didn't know that Sweden did that "enrichment" + destroys at the same time my idea of "milk" just being "milk").
In general I would think that if there are countries that are not poor in relation to vitamin D, then it would be Sweden & Norway, as I understand that fish does contain a lot of vitamin D (random hit here: https://www.healthline.com/nutrition/9-foods-high-in-vitamin... ) (at the same time I'm subjectively assuming that people in Sweden & Norway & other nordic countries eat a lot more fish that others) => I'm therefore conflicted: if that's correct, assuming as well that the population eats fish (relatively often), then why enrich milk with extra vitamin D?
