Sun exposure and vitamin D levels may play a strong
role in risk of type 1 diabetes in children, according
to new findings by researchers at the Moores Cancer
Center at University of California, San Diego (UCSD)
and the Department of Family and Preventive Medicine.
This association comes on the heels of similar research
findings by this same group regarding vitamin D levels
and several major cancers.
In this new study, the researchers found that populations
living at or near the equator, where there is abundant
sunshine (and ultraviolet B irradiance) have low
incidence rates of type 1 diabetes. Conversely,
populations at higher latitudes, where available
sunlight is scarcer, have higher incidence rates.
These findings add new support to the concept of a
role of vitamin D in reducing risk of this dis-ease.
Ultraviolet B (UVB) exposure triggers photosynthesis
of vitamin D3 in the skin. This form of vitamin D
also is available through diet and supplements.
That is why I will be releasing a new Young
pHorever formula of Vitamin D and antioxidant
herbs this summer.
“This is the first study, to our knowledge, to show
that higher serum levels of vitamin D are associated
with reduced incidence rates of type 1 diabetes
worldwide,” said Cedric F. Garland, Dr. P.H., professor
of Family and Preventive Medicine in the UCSD School of
Medicine, and member of the Moores UCSD Cancer Center.
The study is published June 5 in the online version of
the scientific journal Diabetologia.
Type 1 diabetes is the second most common chronic
dis-ease in children, second only to asthma. Every
day, 1.5 million Americans deal with type 1 diabetes
and its complications. About 15,000 new cases are
diagnosed in the United States each year, where this
dis-ease is the main cause of blindness in young and
middle-aged adults and is among the top reasons for
kidney failure and transplants in youth and midlife.
“This research suggests that childhood type 1 diabetes
may be preventable with a modest intake of vitamin D3
(1000 IU/day) for children, ideally with 5 to 10
minutes of sunlight around noontime, when good weather
allows,” said Garland. “Infants less than a year old
should not be given more than 400 IU per day without
consulting a doctor. Hats and dark glasses are a
good idea to wear when in the sun at any age, and can
be used if the child will tolerate them.”
The association of UVB irradiance to incidence of
type 1 diabetes remained strong even after the
researchers accounted for per capita health care
expenditure. This was an important consideration
because regions located near the equator tend to
have lower per capita health care expenditures,
which could result in under-reporting of type 1
diabetes.
The researchers created a graph with a vertical axis
for diabetes incidence rates, and a horizontal axis
for latitude. The latitudes range from -60 for the
southern hemisphere, to zero for the equator, to +70
for the northern hemisphere. They then plotted
incidence rates for 51 regions according to latitude.
The resulting chart was a parabolic curve that looks
like a smile.
In the paper the researchers call for public health
action to address widespread vitamin D inadequacy
in U.S. children.
“This study presents strong epidemiological evidence
to suggest that we may be able to prevent new cases
of type 1 diabetes,” said Garland. “By preventing this
disease, we would prevent its many devastating
consequences.”
Dr. Robert O. Young, a research scientist at the pH
Miracle Center states, "the primary cause of type 1
diabetes is congestion and/or damage to the intestinal
villi of the small intestine from ingesting protein
and sugar. Children that are having problems with
high blood sugars can reverse this quickly by getting
off animal protein and sugar and starting an alkaline
lifestyle and diet. One part of this diet includes
nutritional supplementation of 1000 I.U.'s of
vitamin D, liquid chlorophyll, healthy oils,
alkaline water and or course liberal amounts
of mineral salts."
