I just finished the book The Power of Vitamin D, by Dr. Sarfraz Zaidi. I found it to be an interesting read, but I'm not entirely certain what to think of it-- I'm having trouble finding balanced opinions of his work.
His arguments are compelling. Most people are significantly deficient in vitamin D, which is something that I've heard from many sources (including my own physician.) Vitamin D is a hormone that is vital to quite a few metabolic processes, and deficiency can have some fairly nasty repercussions. I'm not a biochemist, but his arguments feel relatively sound to me. It's consistent with other material that I've read about the topic.
On the other hand, his book has more than a whiff of quackery about it. Whenever I see one thing promoted as the miracle cure for a variety of ailments, I get suspicious. When the author says that (some set of people) don't want you to know about this because (whatever reason, usually because it cuts into their profits), I raise a very skeptical eyebrow. When the author has his own line of products to sell you, complete with his smiling mug on the labels, I pretty much call bullshit on the whole thing. Dr. Zaidi scores a bullshit bingo here.
Even with all of the red flags, his book feels to me like it's probably more true than false.
Anyone have information on this?
Also, I really wish it was possible to just waltz into a lab and order your own bloodwork.
