    Vitamin D Is Essential To The Modern Indoor Lifestyle By Michael Holick October 23rd, 2010; Vol.178 #9 (p. 32) Every cell in the body has a vitamin D receptor protein. It's estimated that upwards of 2,000 genes are directly or indirectly regulated by vitamin D.It’s known that vitamin D is necessary for proper bone formation and maintenance. But recent decades have seen a torrent of studies suggesting that vitamin D can also affect many other aspects of health; some scientists have come to consider the daily recommended intake of 400 international units of vitamin D far too low.

    The extent to which vitamin D deficiency may increase susceptibility to a wide range of diseases is dramatically highlighted in research published today. Scientists have mapped the points at which vitamin D interacts with our DNA – and identified over two hundred genes that it directly influences. The results are published today in the journal Genome Research. It is estimated that one billion people worldwide do not have sufficient vitamin D. This deficiency is thought to be largely due to insufficient exposure to the sun and in some cases to poor diet. As well as being a well-known risk factor...

    Vitamin D promises to be the most talked-about and written-about supplement of the decade. While studies continue to refine optimal blood levels and recommended dietary amounts, the fact remains that a huge part of the population — from robust newborns to the frail elderly, and many others in between — are deficient in this essential nutrient. If the findings of existing clinical trials hold up in future research, the potential consequences of this deficiency are likely to go far beyond inadequate bone development and excessive bone loss that can result in falls and fractures. Every tissue in the body, including...

    Previously I have highlighted the benefits vitamin D has with regard to improving the immune response and helping keep infections such as flu at bay. It has been mooted that the upsurge in viral infections during the winter is connected with the generally lower vitamin D levels at this time. The traditional view is that winter infections are due to “indoor crowding.”However, research indicates that flu epidemics do not occur in the summer in crowded workplaces despite the presence of the flu virus around people who should be susceptible to infection. This is based on research by the Centers for...

    The amount of cholesterol circulating in the bloodstream is partly regulated by the brain, a study in mice suggests. It counters assumptions that levels are solely controlled by what we eat and by cholesterol production in the liver. The US study in Nature Neuroscience found that a hunger hormone in the brain acts as the "remote control" for cholesterol travelling round the body.Too much cholesterol causes hardened fatty arteries, raising the risk of a heart attack. The research carried out by a US team at the University of Cincinnati found that increased levels of the hunger hormone ghrelin in mice...

    (NaturalNews) I remember the H1N1 "swine flu" season of 2009 very well. People were rushing out to get vaccinated, scared half to death by the mainstream media which was pushing false reports that the swine flu would kill tens of millions of people and that only a vaccine could save you. The CDC and health authorities were pushing a double-barreled vaccine strategy that demanded people get both a seasonal flu shot as well as an H1N1 pandemic flu shot. Those who questioned the sensibility of vaccines for fighting the flu were attacked as "baby killers" for not kow-towing to the...

    MADISON — For more than 30 years, scientists have known that multiple sclerosis (MS) is much more common in higher latitudes than in the tropics. Because sunlight is more abundant near the equator, many researchers have wondered if the high levels of vitamin D engendered by sunlight could explain this unusual pattern of prevalence. Vitamin D may reduce the symptoms of MS, says Hector DeLuca, Steenbock Research Professor of Biochemistry at University of Wisconsin-Madison, but in a study published in PNAS this week, he and first author Bryan Becklund suggest that the ultraviolet portion of sunlight may play a bigger...

The bad news comes from estimates prepared by the World Health Organization, which asserted this week that drug resistant tuberculosis is on the rise in other parts of the globe, most notably in Russia, India and China.  In fact, of the 440,000 cases of resistant TB reported in 2008, one third died and half were in India and China.  As a result, WHO is urging these countries to devote entire...

    WINSTON-SALEM, N.C. – Vitamin D is quickly becoming the "go-to" remedy for treating a wide range of illnesses, from osteoporosis to atherosclerosis. However, new evidence from a Wake Forest University School of Medicine study suggests that supplementing vitamin D in those with low levels may have different effects based on patient race and, in black individuals, the supplement could actually do harm. The study is the first to show a positive relationship between calcified plaque in large arteries, a measure of atherosclerosis or "hardening of the arteries," and circulating vitamin D levels in black patients. It appears in the March...

    Taking high doses of vitamin D3 supplements in winter helps reduce risk of acquiring seasonal flu in winter, a new Japanese trial demonstrated. The trial results, reported in the March 10, 2010 issue of American Journal of Clinical Nutrition, show that children given vitamin D(3) supplement were 42 percent less likely to get infected with seasonal flu than those who were given a placebo. The efficacy is remarkable as it may be comparable to that of flu vaccine, which is generally low because the virus used to construct the vaccine is likely different from the circulating one.

  • Vitamin D and calcium interplay explored

    Increasing calcium intake is a common--yet not always successful--strategy for reducing bone fractures. But a study supported in part by the Agricultural Research Service (ARS) underscores the importance of vitamin D and its ability to help the body utilize calcium. The study also may explain why increasing calcium alone isn't always successful in dealing with this problem. Currently, calcium intake recommendations are not tied to vitamin D status, which may explain why markedly different recommended calcium intakes exist among countries. In the United States, the recommended calcium intake is 1,200 milligrams (mg) daily for adults aged 50 and older. The...

    SNOWMASS, COLO. — Serious questions exist about the safety and efficacy of the popular practice of high-dose vitamin D supplementation across a broad swath of the population. One of these concerns is that not all of the extra calcium absorption promoted by boosting vitamin D is going into bone to prevent fractures. Some of it may actually be taken up by atherosclerotic plaque, increasing the risk of cardiovascular events, Dr. Lenore M. Buckley cautioned at a symposium sponsored by the American College of Rheumatology. This is of particular concern in patients with known coronary disease and for those at high...

    Vitamin D Crucial To Activating Immune DefensesScientists at the University of Copenhagen have discovered that Vitamin D is crucial to activating our immune defenses and that without sufficient intake of the vitamin, the killer cells of the immune system – T cells - will not be able to react to and fight off serious infections in the body. For T cells to detect and kill foreign pathogens such as clumps of bacteria or viruses, the cells must first be 'triggered' into action and 'transform' from inactive and harmless immune cells into killer cells that are primed to seek out and...

    As recently as a decade ago, vitamin D was mostly thought of as a helper-nutrient - it allowed the body to absorb and use calcium for strong bones. With a diet of fortified foods and a little bit of sunshine every day, most people got plenty of it. But that was years ago. Today, research suggests that vitamin D does much more than help build strong bones, and the findings come at a time when a high number of people are no longer getting enough of the nutrient, doctors say.

    Effects of vitamin D deficiency amplified by shortage of estrogenResearchers at Johns Hopkins are reporting what is believed to be the first conclusive evidence in men that the long-term ill effects of vitamin D deficiency are amplified by lower levels of the key sex hormone estrogen, but not testosterone. In a national study in 1010 men, to be presented Nov. 15 at the American Heart Association's (AHA) annual Scientific Sessions in Orlando, researchers say the new findings build on previous studies showing that deficiencies in vitamin D and low levels of estrogen, found naturally in differing amounts in men and...

    > Magnesium is a must. The diets of all Americans are likely to be deficient. Even a mild deficiency causes sensitiveness to noise, nervousness, irritability, mental depression, confusion, twitching, trembling, apprehension, insomnia, muscle weakness and cramps in the toes, feet, legs, or fingers. Folic acid deficiency can lead to neural tube closure defects (NTDs) and anemia. Zinc deficiency affects immune function, contributing to as many as 800,000 child deaths per year. Iodine deficiency is the leading preventable cause of brain damage and it can significantly lower the IQ of whole populations. >

    It's emblazoned across the front page of USA Today, just underneath a subhead declaring Michael Jackson was, indeed, killed by a drug overdose: "Flu could infect half of USA." The article goes on to describe the predicted number of deaths expected in the U.S. (30,000 - 90,000 Americans) as well as the actions being taken by the government to protect Americans from the coming swine flu pandemic. That advice reads sort of like a comic book of health care advice for kindergarteners: Wash your hands, cover your mouth if you cough and let "the grownups" take care of the rest...

    With new studies showing the sun vitamin may slow come cancers, some physicians are eager to add it to treatment programs Responding to research indicating that vitamin D may slow the progression of breast, colon and other common cancers, some doctors have begun adding the supplement to their tool kit of cancer therapies alongside more conventional treatments such as radiation, surgery and chemotherapy. While not all physicians are convinced the evidence is strong enough to warrant taking an extra dollop of the sunshine vitamin, those recommending the course say popping the pills is a simple health strategy that has few,...

    Supplements of the sunshine vitamin may improve insulin resistance and sensitivity, both of which are risk factors for diabetes, says a new study from New Zealand. Insulin resistance, whereby insufficient insulin is released to produce a normal glucose response from fat, muscle and liver cells, was significantly lower in women following high-dose vitamin D supplementation, according to results of a randomised, controlled, double-blind trial published in the British Journal of Nutrition. The optimal effects were observed when blood vitamin D levels were in the range 80 to 119 nanomoles per litre, said the researchers, “providing further evidence for an increase...

    CHICAGO – At least one in five U.S. children aged 1 to 11 don't get enough vitamin D and could be at risk for a variety of health problems including weak bones, the most recent national analysis suggests. By a looser measure, almost 90 percent of black children that age and 80 percent of Hispanic kids could be vitamin D deficient — "astounding numbers" that should serve as a call to action, said Dr. Jonathan Mansbach, lead author of the new analysis and a researcher at Harvard Medical School and Children's Hospital in Boston. > The body also makes vitamin...

    Among women enrolled in the Michigan Bone Health and Metabolism Study high blood pressure developed at 3 times the rate in women who were vitamin D deficient before menopause. Do not wait until you get older before starting to take nutrition seriously. If you wait the damage will already be done before you act. <snip> CHICAGO, Sept. 23, 2009 — A high-fructose diet raises blood pressure in men, while a drug used to treat gout seems to protect against the blood pressure increase, according to research reported at the American Heart Association’s 63rd High Blood Pressure Research Conference.

    Can an over-the-counter vitamin-like substance slow the progression of Parkinson's disease? Rush University Medical Center is participating in a large-scale, multi-center clinical trial in the U.S. and Canada to determine whether a vitamin-like substance, in high doses, can slow the progression of Parkinson's disease, a neurodegenerative disorder that affects about one million people in the United States. "At present, the very best therapies we have for Parkinson's can only mask the symptoms – they do not alter the underlying disease," said neurologist Dr. Katie Kompoliti, a specialist in movement disorders. "Finding a treatment that can slow the degenerative course of...

    A new study by researchers at the University of Colorado Denver and Massachusetts General Hospital (MGH) shows vitamin D plays a vital role in reducing the risk of death associated with older age. The research, just published in the Journal of the American Geriatrics Society, evaluated the association between vitamin D levels in the blood and the death rates of those 65 and older. The study found that older adults with insufficient levels of vitamin D die from heart disease at greater rates that those with adequate levels of the vitamin. "It's likely that more than one-third of older adults...

    Humans come in a rainbow of hues, from dark chocolate browns to nearly translucent whites. This full kaleidoscope of skin colors was a relatively recent evolutionary development, according to biologists, occuring alongside the migration of modern humans out of Africa between 100,000 and 50,000 years ago. The consensus among scientists has always been that lower levels of vitamin D at higher latitudes — where the sun is less intense — caused the lightening effect when modern humans, who began darker-skinned, first migrated north. But other factors might be at work, a new study suggests. From the varying effects of frostbite...

    A deficiency of the sunshine vitamin may worsen plaque accumulation in vessels of diabetes patients Vitamin D deficiency may exacerbate the excess heart disease risk that people with type 2 diabetes face, a new study in the Aug. 25 Circulation suggests. In lab tests, researchers demonstrate that immune cells with very low vitamin D levels turn into soggy, cholesterol-filled baggage that can become building blocks of arterial plaques. Carlos Bernal-Mizrachi, an endocrinologist at Washington University School of Medicine in St. Louis, and his colleagues found that people with diabetes seem more susceptible than nondiabetics to the negative cardiovascular effects attributable...
