If the name Michael Holick means anything to you, you will recall that he was asked to resign from a post in Boston University’s dermatology department in February 2004 for promoting “sensible sun exposure” in his book The UV Advantage.
Holick’s thesis—which was apparently anathema to Boston University derm department chair Barbara Gilchrest—is that most people who live in the US north of Atlanta are vitamin D deficient because one of the key sources of that vitamin is the sun. (Vitamin D is essential for the absorption of calcium and thus strong, healthy bones.) And even when the sun shines brightest, and for the longest, during the summer, we’re told to shun the sun and slather our bodies in high SPF sunscreens to defend against skin cancer.
