A new study suggests that more than
half of older Americans might not be getting enough bone-building
Research published in the New
England Journal of Medicine found more than half of the patients
admitted to a Boston hospital were deficient in the vitamin, and
nearly a quarter of them had blood serum concentrations less than
half the amount thought necessary to preserve bone mass.
Earlier studies of homebound seniors
and nursing home residents had found between a quarter and half
of elderly people to be low on the vitamin, depending on the yardstick
But Dr. Joel Finkelstein of Massachusetts
General Hospital and colleagues looked at a more diverse group,
290 patients ages 18 to 95 admitted in March and September 1994.
"Although we expected to see
significant levels of vitamin D deficiency in the patients, we were
surprised that the results were so dramatic," Finkelstein said.
"This suggests vitamin D deficiency is more common than currently
appreciated in the general population as well."
In particular, among a subgroup of
77 patients in the study who were under 65 and had none of the other
risk factors linked with deficiency, 41 percent still had low D
"This suggests that the standard
clinical indicators may not adequately predict who is at risk for
vitamin D deficiency," said Dr Melissa Thomas, a study co-author.
Vitamin D helps the body absorb calcium
and phosphorus, two major components of bone. and helps bones harden.
The body makes the vitamin when exposed to sunlight, but most people
living anywhere but the tropics need to get at least some vitamin
D from their diets, and this need increases as people age because
older skin also produces less of the vitamin.
Not getting enough vitamin D can contribute
to reduced bone mass and increased risk of fractures, and
may weaken other organs and the immune system.
Few foods have much vitamin D, although
fortified milk and some
fatty fish, like salmon and mackerel, are good sources, as are many
fortified cereals. But unless they drink more than a quart of milk
a day, most people need to take a vitamin supplement, particularly
if they're older or during seasons they're getting little or no

Cancer Prevention-Evidence of vitamin D's
protective effect against cancer is compelling. For more than 50
years, documentation in the medical literature suggests regular
sun exposure is associated with substantial decreases in death rates
from certain cancers and a decrease in overall cancer death rates.
Recent research suggests this is a causal relationship that acts
through the body's vitamin D metabolic pathways. For instance, some
evidence points to a prostate, breast and colon cancer belt in the
United States, which lies in northern latitudes under more cloud
cover than other regions during the year Rates for these cancers
are two to three times higher than in sunnier areas.
Dark-skinned people require more sun exposure
co make vitamin D. The thickness of the skin layer called the stratum
corneum affects the absorption of UV radiation. Black human skin
is thicker than white skin and thus transmits only about 40 percent
of the UV rays for vitamin D production. Darkly pigmented individuals
who live in sunny equatorial climates experience s higher mortality
rate (not incidence) from breast and prostate cancer when they move
to geographic areas that are deprived of sunlight exposure in winter
months. The rate of increase varies, and researchers hesitate to
quote figures because many migrant black populations also have poor
nutrition and deficient health care thai confound statistics somewhat.
Although excessive sun exposure may give
rise to skin cancer, researchers as early as 1936 were aware that
skin cancer patients have reduced rates
of other cancers. One researcher estimates moderate sunning would
prevent 30.000 annual cancer deaths in the United States.
Vitamin D may
also go beyond cancer prevention and provide tumor therapy. Much
ado has been made of pharmaceutical angio-genesis inhibitors —
agents that help inhibit the growth of new, undesirable blood vessels
that tumors require for nutrient supply and growth. Laboratory tests
have shown vitamin D to be a potent angiogenesis inhibitor.
Vitamin D also
works at another stage of cancer development. Tumor cells are young,
immortal cells that never grow up, mature and die off. Because vitamin
D derivatives have been shown to promote normal cell growth and
maturation, drug companies today are attempting to engineer patentable
forms of vitamin D for anti-cancer therapy.
Up until now, vitamin D has been better known for its ability to
promote bone strength by increasing calcium absorption. Supplemental
vitamin D has been shown to reduce hip fracture risk among elderly
women when combined with supplemental calcium. In one study of 3.270
healthy women, mean age 34, 1,634 received 1.2g calcium and 800
international units (IU) vitamin D3, while the other 1,636 received
placebo. During the 18-month study, the supplemented group experienced
43 percent fewer hip fractures, 32 percent fewer non-vertebral fractures,
and a 2.7 percent increase in bone density of the proximal femur
vs. the 4.6 percent bone density decrease seen in the placebo group.
bear out vitamin D's importance to bone health, to the point where
it's now widely known that vitamin D deficiency is associated with
hip fractures, and supplementation helps. Unfortunately, not everyone
is getting enough vitamin D. A recent study reveals that about 10
percent of retirees in Boston social clubs are vitamin D deficient
(< 15ng/mL serum vitamin D) compared with 21 percent of hip-fracture
patients at the Massachusetts General Hospital. So experts now suggest
people take 600 IU vitamin D daily, and up to 800 !U a day for elderly
patients who do not produce vitamin D from sun exposure as easily
as they did when younger. A recent study showed that 37 percent
of adult hospital patients were deficient in vitamin D upon admission.
Two-thirds of these patients did not consume enough vitamin D from
dietary sources. Surprisingly, 46 percent of those who took
daily multivitamins (most of which provide 400 IU) were also in
a state of deficiency.

ACCORDING TO A STUDY published in the Journal of the American
Medical Association, many postmenopausal women are still unaware
of the critical role vitamin D plays in preventing fractures. This
nutrient helps the body use calcium to maintain strong bones, but
more public awareness is necessary to emphasize D's importance,
says Dr. Meryl S. LeBoff, lead study author and director of the
osteoporosis program at Brigham and Women's Hospital in Boston.
Loading up on calcium without adequate vitamin D could still leave
bones at risk. In their study, researchers compared 30 women with
hip fractures with 68 women who didn't have fractures. Half the
broken-hip group had vitamin-D deficiencies.
Common sources of vitamin D include eggs
and fortified milk and cereal. Experts advise asking your doctor
about supplements. — AP

(by Robert Barefoot) The following
is an excerpt from an article written by Robert Barefoot.
....Typical of articles attempting to perpetuate
the myth that God's nutrient, vitamin-D, is toxic, the article not
only provides misinformation, it also uses arguments that are not
true. For example it states that "there have been no systematic
studies to determine vitamin-D toxicity for humans". This is
simply not true. In my book, The Calcium Factor, I provide
10 such studies, all of which "conclude that vitamin-D is not
toxic." Many of these were ten year studies done on hundreds
of animals and humans. Studies that were carried out by our best
scientists and doctors at our best scientific research establishments.
For example, the Streck Report of 1937, "Further Studies
on Intoxification With Vitamin-D", which was done at the
University of Chicago Medical Facility and took dozens of doctors
and scientists nine years to complete, concluded that they found
large doses of vitamin D to be non toxic and, because of the correlation
of their animal studies to their human studies, they concluded that
"the burden of proof rests with those who claim the undesirability
of vitamin D therapy." This study was followed up by other
massive studies which all concluded the non toxicity of vitamin
Finally, this article did provide information
that proved that vitamin D, in the amounts such as 1200 IU and 2000
IU which they claimed were toxic, just simply could not possibly
be toxic. It is simple because all one has to do is apply grade
8 math to the numbers provided in the article. The article refers
to a paper "Cholecalciferol Production", P.C. Beadle,
where Beadle measured the vitamin-D production in the epidermis
(skin) to be 163 IU per square centimeter in light skin per day
and 69 IU per square centimeter in dark skin per day.
The human body has about 20 square feet
of skin or 18,600 square centimeters. This means that the human
body can produce over 3,000,000 IU of non toxic vitamin D per day.
Also, the article suggests that 30 minutes of sunshine per week
produces enough vitamin D for the human body. Assuming this to be
true, and also assuming 12 hours of sunlight per day, the amount
of vitamin D produced in 30 minutes is 128,000 IU which calculates
to 18,300 IU per day. This means that they are advising that 18.300
IU of vitamin D are required by the human body per day (which this
author wholeheartedly supports), while saying that 1200 IU "may
be toxic". This is ludicrous as the healthiest people in the
world, the Hunzas in Pakistan, the Bamas in China, the Georgians
in Russia, the Titi Cacas in Peru and the Okinawans in Japan, all
of whom have virtually no diseases, all get about 7 hours of sunshine
each day and therefore produce about 500,000 IU of Vitamin-D each
day (their skin is dark). Thus the logic of the Ph.D.'s lies in
the ruins of grade eight math.

Receptors for vitamin D are found in most
of the cells in the body and research during the 1980's suggested
that vitamin D contributed to a healthy immune system, promoted
muscle strength, regulated the maturation process and contributed
to hormone production.
During the last ten years, researchers have
made a number of exciting discoveries about vitamin D. They have
ascertained, for example, that vitamin D is an antioxidant that
is a more effective antioxidant than vitamin E in reducing lipid
peroxidation and increasing enzymes that protect against oxidation.
Vitamin D deficiency decreases biosynthesis
and release of insulin. Glucose intolerance has been inversely associated
with the concentration of vitamin D in the blood. Thus, vitamin
D may protect against both Type I and Type II diabetes.
The risk of senile cataract is reduced in
persons with optimal levels of D and carotenoids.
PCOS (Polycystic Ovarian Syndrome) has been
corrected by supplementation of D and calcium.
Vitamin D plays a role in regulation of
both the "infectious" immune system and the "inflammatory"
Low vitamin D is associated with several
autoimmune diseases including multiple sclerosis, Sjogren's Syndrome,
rheumatoid arthritis, thyroiditis and Crohn's disease.
Osteoporosis is strongly associated with
low vitamin D. Postmenopausal women with osteoporosis respond favorably
(and rapidly) to higher levels of D plus calcium and magnesium.
D deficiency has been mistaken for fibromyalgia,
chronic fatigue or periphereal neuropathy.
Infertility is associated with low vitamin
D. Vitamin D supports production of estrogen in men and women. PMS
has been completely reversed by addition of calcium, magnesium and
vitamin D. Menstrual migraine is associated with low levels of vitamin
D and calcium.
Breast, prostate, skin, and colon cancer
have a strong association with low levels of D and lack of sunlight.
Activated vitamin D in the adrenal gland
regulates tyrosine hydoxylase, the rate limiting enzyme necessary
for the production of dopamine, epinephrine and norepinephrine.
Low D may contribute to chronic fatigue and depression.
High stress may increase the need for vitamin
D or UV-B sunlight and calcium.
People with Parkinson's and Alzheimer's
have been found to have lower levels of vitamin D.
Low levels of D, and perhaps calcium, in
a pregnant mother and later into he child may be the contributing
cause of "crooked teeth" and myopia. When these conditions
are found in succeeding generations it means the genetics require
higher levels of one or both nutrients to optimize health.
Behavior and learning disorders respond
well to D and/or calcium combined with an adequate diet and trace
Administration of dietary vitamin D or UV-B
has been shown to lower blood pressure, restore insulin sensitivity
and lower cholesterol.
Did you ever wonder why some people can eat all they want and not
get fat, while others are constantly battling extra pounds? The
answer may have to do with vitamin D and calcium status. SUnlight,
UV-B, and vitamin D normalize food intake and normalize blood sugar.
Weight normalization is associated with higher levels of vitamin
D and adequate calcium. Obesity is associated with vitamin D deficiency.
In fact, obese persons have impaired production of UV-B-stimulated
D and impaired absorption of food source and supplemental D.
When the diet lacks calcium, whether from
D or calcium deficiency, there is an increase in fatty acid syntheses,
an enzyme that converts calories into fat. Higher levels of calcium
with adequate vitamin D inhibit fatty acid syntheses while diets
low in calcium increase fatty acid syntheses by as much as five-fold.
In one study, genetically obese rats lost 60 percent of their body
fat in 6 weeks on a diet that had moderate calorie reduction but
was high in calcium. All rats supplemented with calcium showed increased
