Vitamin D Slashes Cancer and Heart Disease Risk in Half

Health conscious individuals have been closely following Vitamin D research for the past decade as volumes of scientific evidence prove this prohormone has been selected through our evolution to provide critical protection against many inflammatory and immune mediated diseases.

New information now reveals a clear picture of how this amazing nutrient works at the cellular level while prompting the expression of more than 3000 individual genes to protect us against many lethal forms of cancer and heart disease as well. You can dramatically reduce your risk of illness and extend your healthy lifespan by making sure your blood is saturated at an optimal level with Vitamin D.

Vitamin D Influences our Genes, Cuts Cancer Risk in Half
Research has determined that virtually every cell in the human body has evolved with a Vitamin D receptor (VDR) which needs to be filled with circulating Vitamin D from our blood. Insufficient levels of the nutrient means that cellular receptors will be left open to be hijacked by a rogue virus. This can pave the way for infection by the influenza virus or eventually lead to a greatly increased risk of cancer.

According to a study published in Genome Research, Vitamin D regulates genes which provide protection against many forms of cancer and autoimmune diseases. Vitamin D specifically binds with these genes to provide a protective shield which dramatically reduces our risk of disease. Vitamin D also acts as a master blueprint for cellular replication, guiding the DNA strands with instructions to accurately divide during mitosis and provides critical guidance to prevent cellular proliferation, a hallmark of cancer metastasis.

Vitamin D Lowers Heart Disease Risk by 47%
The results of a study presented to the American College of Cardiology show that correcting deficient Vitamin D blood levels can reduce the risks associated with coronary artery disease. Study participants were given Vitamin D supplements to raise their blood level well beyond the current minimum reference point and were followed for a period of a year to assess their risk for cardiovascular disease. While this study didn`t provide an explanation for the 47% risk reduction, other research has shown that Vitamin D can lower systemic inflammation throughout the body which promotes healthy arteries and lowers blood pressure.

Ensure You Aren`t Vitamin D Deficient
As much as 85% of the adult population is Vitamin D deficient, needlessly placing themselves at considerable risk for a variety of diseases ranging from flu and the common cold to heart disease and cancer. Sun exposure and multi vitamins are inconsistent sources of Vitamin D as we lose the ability to convert the nutrient to its active form on our skin as we age.

The only way to accurately determine if you need to supplement is by having your blood tested. Be sure to request a 25(OH)D blood test which yields the most accurate results. Optimal levels are between 50 and 70 ng/mL. If you test below this level you`ll need to supplement with an oil-based gelcap form of Vitamin D. Most people find that 1000 IU is needed to raise the blood level by 10 ng/mL.

Deficient levels of Vitamin D are responsible for millions of needless deaths and much suffering each year. Extensive research has shown exactly how this mega nutrient works on the cellular level to provide lowered risk from many lethal conditions including cancer and heart disease. Those interested in lowering disease risk will want to have a simple blood test and supplement accordingly to reap a multitude of health benefits.

PROFESSOR Frank Garland, and his brother, Cedric, recommend [...] taking 50,000 units of vitamin D per week for eight to twelve weeks followed by maintenance on 1,000 to 2,000 units a day”.
ACCORDING Cedric F. Garland, Dr. P.H., FACE, Department of Family and Preventive Medicine and Moores Cancer Center of the University of California, San Diego (UCSD), “It is projected that raising the minimum year-around serum 25(OH)D level to 40-60 ng/ml (100-150 nmol/L) would prevent approximately 58,000 new cases of breast cancer and 49,000 new cases of colorectal cancer each year, and three quarters of deaths from these diseases, in the US and Canada.”
Plasma vitamin D and mortality in older men: a community-based prospective cohort study.
“There was a U-shaped association between vitamin D concentrations and total mortality. An approximately 50% higher total mortality rate was observed among men in the lowest 10% (<46 nmol/L) and the highest in the highest 5% (>98 nmol/L [or 39 ng/ml]) of plasma 25(OH)D concentrations compared with intermediate concentrations. Both high and low concentrations of plasma 25(OH)D are associated with elevated risks of overall and cancer mortality.

“African Americans … are more likely to be vitamin D deficient due to their darker skin pigmentation’s ability to block the sun’s rays”
It is not true that melanin blocks the wavelengths which synthesize vitamin D . The value of melanin as a sunscreen (2010).
“epidermal melanin is not a neutral density filter providing no or minimal protection for the induction of erythema at 295 and 315 nm and some protection at 305 and 365 nm”
It does block 305nm but around that wavelength is the most damaging A UVB Wavelength Dependency for Local Suppression of Recall Immunity in Humans Demonstrates a Peak at 300 nm. also see Erythema curve. Note the relative danger curve ( yellow) peaks at around 305nm
T the blocking of a limited spectra of vitamin D synthesizing UVB doesn’t matter the other wavelengths get through. Blood vitamin D levels in relation to genetic estimation of African ancestry “found novel evidence that the level of African ancestry [rather than skin pigmentation] may play a role in clinical vitamin D status”.
There is a negative feedback system; evolution has has got vitamin D levels just right
Klotho protein deficiency and aging.
“α-Klotho protein is shown to function in the negative feedback regulation of vitamin D3 synthesis These observations indicated that abnormal vitamin D3 metabolism is the main cause of aging phenotypes.″
Klotho was named after one of the Moirae or fates, supplementing vitamin D is indeed a fateful step.

Many people of tropical ancestry have a optimum homeostasis of vitamin D which is below the new IoM levels, but if they're wise they'll not take supplements
