As I say, we are well-studied here, and I fill out forms on what I eat, how I exercise etc. The latest study suggests that vitamin D could be a factor. I think we who live here are good about wearing sun screen, hats, and long-sleeves. We heed the warnings on skin cancer, and may not be getting enough vitamin D, or at least processing it as well as we could.
I suggest we all start taking extra vitamin D. My doctor has told me to, but I've been inconsistent with it. I'm feeling motivated now and I know this study is not conclusive, and is only a start, but it seems like vitamin D is a wise way to participate in our own health care.
