Ok, I admit, saying it gets destroyed was a poor choice of words. But from your article:
>> Although milk as it comes from the cow is a poor source of vitamin D, fortified milk is considered an excellent source, especially because of its calcium content. Other foods considered good dietary sources of vitamin D are relatively rare but do include fatty fish, eggs and liver. Vitamin D is a fat-soluble vitamin.
As for the "destroyed" part of my comment, I meant that both it and vitamin A are fat soluble. So when you "skim" the milk, you lose lots of the vitamins. You lose so much, that vitamin A has to be re-added. Again from your article:
>> As skim and lower fat milks became popular, the reduction of vitamin A levels with fat reduction became an issue since whole milk was considered a good source of vitamin A.
TL;DR - I should've said vitamin A but got lazy/greedy. Vitamin D, while subject to the same problem as vitamin A, is added as refurb explains.
