I'm glad someone is finally warning people of color about vitamin D deficiency--it really is an invidious health condition, and one that's been far too little noted.

Not to mention, our current approach to addressing it is totally stupid. There's a significant overlap in the United States between people who are lactose-intolerant due to heredity and the people who would need Vitamin D supplementation. So, why the heck are we fortifying milk with vitamin D? We should be fortifying other foods. I dunno, maybe cooking oil or some other staple that everyone uses.
