How many cases of rickets have you heard of in the US lately? If vitamin D deficiency were as common as you make it sound, we would have seen a rapid increase in rickets, especially in children.

Not many cases of rickets but plenty of cases of diabetes that we are learning could be partly caused by a long term vitamin D deficiency.
Why do you think people get the flu in the winter and not the summer? Could it possibly be lack of sun exposure causing a D deficiency?

You're misrepresenting the data. Vitamin D deficiency is a risk factor, not a cause, for type II diabetes, and has been connected to poor control of diabetes. Being a male is also a risk factor, but I don't think you would argue that that is a cause of diabetes, would you?

Influenza transmission is tied to a lower humidity in the air, which occurs most often in winter.

I don't tend to trust any site that has a bit "PLEASE GIVE US MONEY" ad at the top. Do you have any peer-reviewed work to support your claims?

I just want to clear something up a little bit, about the sun and vitamin D, if nobody minds.
First, don't get your sunshine through a window or with sunscreen on, because they will filter out the UVB rays. And then you'll only get the UVA rays, which actually deplete your vitamin D. It's the UVB rays that cause your body to produce vitamin D.
Now, someone mentioned that your body makes vitamin D internally. That's a little misleading. What happens is the UVB rays cause your body to produce vitamin D ON YOUR SKIN. And that's not the end of the process. Your body actually needs to absorb the vitamin D back into the body through the skin in order for the vitamin D to do you any good.
The issue people seem to have a problem with is giving their body enough time to absorb their vitamin D. It takes about 48 hours. This means that you shouldn't shower after being out in the sun, and you might want to wait 48 hours at that.
People didn't used to shower every day like we do here now. We think we're healthier showering all the time. But oddly enough, we aren't.
