There deos seem to be a real problem with people getting less D the
last 20 years, and it has been increasing. In the USA, the widespread
use of sunscreen contributes to it, as does not going out in the sun at
all. In addition, so many people live in more northerly latitudes that
do not receive much sun for many months on end. In historic eras, those
who lived in northern regions had less skin pigmentation, which allows
more D to be naturally synthesized in the body. But now people live all
over regardless of skin color.
D is not produced in any food- it is made by our skin, andother
organisms also make it. So supplementation is often necessary. It is in
cod liver oil, does anyone remember the school nurses handing out
tablespoons of cod liver oil? This was to provide D. So this is nothing
new. Now it is easily and cheaply available in pill form, so the need
to force cod liver oil on kids is sooo yeasterday.

For a year or two now I've watched Vitamin D (D3 and more) get
increasing headline space in "natural" news than any other nutrient.
(Please don't pick at my language, it is inexact....if you can tell
what I mean, read on, if not, delete.) Everywhere it seems there is
research going on or at least being reported, showing some amazing
need being met by Vit D.
I don't doubt that it is of benefit to many people because our food
supply is so corrupt and the RDA has been low enough that no doubt
many things are the result of deficiencies. Oh, and global warming.
But why only vitamin D? Is it the only nutrient particle of immense
benefit to the human body?
Is this something here that's patentable? Is it the byproduct of big
biz somewhere?
It reminds me of Soy 15 years ago...which is why I wonder if
something else is going on. This is exactly the way soy began to
become a necessary part of every hidden ingredient and everything we
elect to consume.
Where is the connection? Is there one? What's the real deal?

Vitamin D insufficiency is a global issue
In a report published on June 19, 2009 in the journal Osteoporosis
International, the International Osteoporosis Foundation's expert
working group on nutrition revealed the global extent of vitamin D
insufficiency. They found that suboptimal vitamin D levels are common
in most areas of the world, and appear to be on the rise.
The committee, chaired by Ambrish Mithal of Indraprastha Apollo
Hospitals in New Delhi, India, reviewed published literature
concerning the vitamin D levels of people residing in Asia, Europe,
Latin America, the Middle East and Africa, North America and Oceania.
Although there was some of variance in assay methodology and in the
definition of vitamin D deficiency and insufficiency,
25-hydroxyvitamin levels below 75 nanomoles per liter, which are
generally considered insufficient, were found to be widespread in
every region studied. Older age, female gender, higher latitude,
winter season, dark skin pigmentation, decreased sun exposure, dietary
habits, and a lack of vitamin D fortification were identified as
factors contributing to low vitamin D levels. Levels below 25
nanomoles per liter, indicating deficiency, were prevalent in South
Asia and the Middle East, where increased urbanization and the wearing
of clothing that covers most of the skin are major contributors.
