The Best Years in Life
Winter
Sun Makes It Difficult To Get Vitamin D Naturally
By Tony Isaacs
As the days grow
short in winter, your body may be missing invaluable
Vitamin D needed for optimum health and disease
prevention, according to Creighton University researcher
Joan Lappe, Ph.D.
During the summer, the body can convert solar energy
into ample amounts of vitamin D with just 10-15 minutes
exposure daily to the sun. That's not possible during
the winter months when the angle of the sun sinks lower
into the southern hemisphere.
Dr. Lappe, who is a professor of medicine and holder of
the Criss/Beirne Endowed Chair in the Creighton School
of Nursing, goes on to say that if you live in North
American at latitudes above the 37th parallel you may be
getting little or no Vitamin D at all.
"From October until the end of March, the angle of the
sun is such that, in much of North America, no vitamin D
is available from that source," Lappe said. "What that
means is most of us are deficient in vitamin D this time
of year." The amount of vitamin D you should take daily
is a subject of great debate, Lappe notes.
While there may be a great deal of debate about how much
vitamin D is needed for optimum health, there is little
debate about how valuable Vitamin D is for human health.
Without Vitamin D there would be no human life. Among a
very long list of benefits associated with Vitamin D are
prevention and treatment of : infections and
inflammation, cancer prevention, depression and
neurological disorders, cold and flu, diabetes,
osteoporosis and tuberculosis.
Vitamin D is available from several sources besides the
sun, although it`s difficult to take in adequate amounts
of vitamin D by eating alone. While you can get some
Vitamin D from the vitamin from food source, primarily
fish oil and fish, taking supplemental Vitamin D may be
necessary to get enough of this valuable vitamin. By far
the most effective form of Vitamin D is Vitamin D3, the
form found in nature.
The U.S. government`s recommended daily allowance is 200
IU until age 50, 400 IU for 50-70 year olds, and 600 IU
after age 70. However, many medical experts believe
those recommendations are way too low.
The Canadian Cancer Society recently recommended that
people with light skin take 1,000 IU of the vitamin
supplement during fall and winter, and that people with
darker skin or limited exposure to sunlight take that
amount throughout the year.
The society`s recommendation coincided with the
publication of the Creighton research in June. The
four-year study involving 1,179 Nebraska women showed a
60 percent decrease in the risk of developing canceer
for those who took calcium supplements plus 1,100 IU of
vitamin D3 daily.
On the other hand, Dr. John Cannell, of the prestigious
Vitamin D Council, recommends 5000 units of Vitamin D3
daily for optimum health, and many in the field of
natural health agree.
Note: due to concerns about Vitamin A toxicity, a
growing number of health experts, including Dr. Cannell
and Dr. Mercola are recommending against cod liver oil
as a source of vitamin D3.
