The Vitamin D myth

Jason Kottke and John Gruber both linked to this item from Outside.

For a number of years now in the UK, Vitamin D has been touted as the thing that is missing to keep us healthy. Those of us with darker skin don't get as much sun as we would if we lived somewhere warmer which would cause our bodies to create it's own Vitamin D. Turns out the evidence has been misleading as our bodies generate more than just Vitamin D when exposed to the sun.

My own understanding of Vitamin D was that our bodies used it to help better absorb the things we need, like calcium. But you need calcium to help you absorb Vitamin D which is why they're found in supplements together.

The Sun itself is the thing we miss the most.
