on NPR but other than that, I'm not surprised you haven't heard. The study recently in the NEJof M, I believe, suggests that 15 minutes or so of sunlight/day is actually good for most people but that no one is getting sunlight any more because we've got sunscreen in everything. Heck there are hand lotions that have it in them now. I think it's a matter of moderation just like everything else.

If you have specific concerns about skin cancer, you can boost your Vitamin D in other ways. Do bear in mind that Vitamin D is essential in processing calcium so it's not just the vitamin loss at risk. I certainly understand your concern, but, being osteopenic myself, urge you to consider supplementing the D in other ways.
