I mentioned on this page a few years back that I thought Vitamin D status might simply be a biomarker for sunshine exposure---and that improving health wasn't about taking a D supplement, but about getting more sun. Looks like the science is coming in on this--and yes, we need more sunshine. Part of the Endothelial Health Program since 2008. Joan
"How did we get it so wrong? How could people with low vitamin D levels clearly suffer higher rates of so many diseases and yet not be helped by supplementation?
As it turns out, a rogue band of researchers has had an explanation all along. And if they’re right, it means that once again we have been epically misled.
These rebels argue that what made the people with high vitamin D levels so healthy was not the vitamin itself. That was just a marker. Their vitamin D levels were high because they were getting plenty of exposure to the thing that was really responsible for their good health—that big orange ball shining down from above."

Current guidelines for sun exposure are unhealthy and unscientific, controversial new research suggests—and quite possibly even racist. How did we get it so wrong?
