I wrote the article. It was very hard to write a concise article about all of Vitamin D research, and so I didn't have space to address it, though I really appreciate the feedback. Race and Vitamin D is an interesting area. The VITAL trial, which is the largest study on Vitamin D that we have, with 25,000 participants, tried to enroll more Blacks, and in the end 20% of the participants were Black. They showed the same results, but interestingly it did seem like there might be a trend toward fewer cancers for Blacks who received Vitamin D, but this was not definitive. More research on this is needed.

The other reason I didn't get into race and Vitamin D is that we then start getting into the blood levels, and what really constitutes deficiency. I think we are a little too liberal with our diagnosis of deficiency right now.
