I admit to being a big fan of Vitamin D and the role it plays in our health—especially when it comes from natural sources, such as the interaction of sunshine and our skin. (See previous posts Hold That Sunscreen!; Vitamin D; and Sunshine, Vitamin D, and Why I'm Skeptical of the Medical Establishment's Confidence in Its Broad Pronouncements.) Regular readers will not be surprised that I managed to find time, despite the busiest December we've had in recent memory, to listen to the entire hour of the following MedCram interview, which discusses the possible correlation between high levels of vitamin D in the blood and favorable COVID-19 outcomes.

Despite the length—or perhaps because of it—it is my kind of informative interview. it is full of enough charts, graphs, and data to make your head spin, and even more importantly of the kind of phrasing I'm accustomed to in scientific discussions, and which I've found so sorely lacking in scientific pronouncements these days. Words like, "we don't know for sure," "correlation does not prove causation," and "this study shows X, and suggests but does not prove Y."

Despite the hedging—or again maybe because if it—this information strongly encourages me to resume my former habit of taking a daily "sun walk" for at least 15 minutes of sun exposure on as much skin as I can reasonable turn to the sun. It's easier to do that here in Florida where the sun is more direct and short sleeves usually the order of the day, so it's good to know that this interview suggests that vitamin D supplements are also effective. I still prefer the sun/skin partnership, which produces helpful nitric oxide as well as vitamin D, but we take what we can get. I'm sure I'd be better off if I liked sardines as well.
