A
New Epidemic?
By Dan Farrell
A
recent article in the Reader's Digest points out some rather startling
new information, at least to this author, that according to Michael
Holick, who's spent the last 30 years researching the subject, believes
we're living in an unrecognized epidemic of Vitamin D deficiency. And
scientists are linking low levels of D to cancer, hypertension, diabetes
and osteoporosis.
Researchers
used to think that Vitamin D was for building strong bones but new research
shows that this humble nutrient is far more versatile.
Unlike
most vitamins, D isn't found in much we eat, other than fortified milk
and coldwater fish like mackerel and salmon. Most of it is supplied
by the sun. D-related hormone in the skin soaks up the ultraviolet rays
in sunlight and travels to the liver and the kidneys, where it is picked
up by extra molecules of oxygen and hydrogen.
This
process transforms this potent hormone into calcitriol. Scientists believe
that this disease fighting calcitriol is very important to prevent the
above diseases.
Let
the sun bake on your unprotected arms and face for a few minutes and
you will have all the D you need.
In
northern climes though it is believed that there is a deficiency from
20 to 60 percent among those over 50.
A
startling fact is that there is more and more rickets every because
doting parents are breastfeeding their infants and keeping them out
of the sun.
Here
are the recommended daily doses for Vitamin D:
Under
50 = 200IU's a day 51-69 = 400IU's a day over 70 = 600IU's a day More
than 2,000IU's can lead to a toxic buildup of calcium in the bloodstream.
Getting
800IU's isn't that hard. An 8-ounce cup of milk contains almost 100IU's.
For lactose intolerant or those who don't like milk, Minute Maid offers
D-fortified orange juice.
Better
still, get outside (but without sunscreen).
