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...

White Europeans could have evolved as recently as 5,500 years ago, according to research which suggests that the early humans who populated Britain and Scandinavia had dark skins for millenniums. It was only when early humans gave up hunter-gathering and switched to farming about 5,500 years ago that white skin began to be favoured, say the researchers. This is because farmed food was deficient in vitamin D, a vital nutrient. Humans can make this in their skin when exposed to sunlight, but dark skin is much less efficient at it. In places such as northern Europe, where sunlight levels are...

Aug. 21, 2009 -- Low levels of vitamin D are known to nearly double the risk of cardiovascular disease in patients with diabetes, and researchers at Washington University School of Medicine in St. Louis now think they know why. They have found that diabetics deficient in vitamin D can't process cholesterol normally, so it builds up in their blood vessels, increasing the risk of heart attack and stroke. The new research has identified a mechanism linking low vitamin D levels to heart disease risk and may lead to ways to fix the problem, simply by increasing levels of vitamin D....

Increasing blood levels of vitamin D are linked to a lower prevalence of the metabolic syndrome, as well as improved 'good' cholesterol levels, says a new study. According to findings published in the Journal of Clinical Lipidology, the lowest levels of the sunshine vitamin were associated with a 31 per cent prevalence of metabolic syndrome, compared to only 10 per cent for people wit the highest average levels. The researchers noted that the results do not prove that low vitamin D levels contributes or causes metabolic syndrome, and called for more studies to "assess whether increasing vitamin D intake...

BOSTON — The high prevalence of vitamin D deficiency found in a cohort of healthy children in a sunny Southwestern climate has prompted a call by the study's investigators for generalized routine screening of vitamin D levels among all children. In a study designed to assess vitamin D levels in children living in a region with year-round sunshine and to compare vitamin D levels in children with vague musculoskeletal pain with those of children without pain, Dr. Elizabeth A. Szalay and her colleagues at the University of New Mexico Hospital in Albuquerque retrospectively studied the serum 25-hydroxyvitamin D (25[OH]D) levels...

Early research findings may lead to new treatments for the diseaseUCLA scientists and colleagues from UC Riverside and the Human BioMolecular Research Institute have found that a form of vitamin D, together with a chemical found in turmeric spice called curcumin, may help stimulate the immune system to clear the brain of amyloid beta, which forms the plaques considered the hallmark of Alzheimer's disease. The early research findings, which appear in the July issue of the Journal of Alzheimer's Disease, may lead to new approaches in preventing and treating Alzheimer's by utilizing the property of vitamin D3 — a form...

NaturalNews) Children who develop multiple sclerosis have substantially lower levels of vitamin D than children who do not develop the disease, according to a series of studies presented at an international conference on multiple sclerosis in Montreal. Multiple sclerosis is a degenerative disease of the nervous system in which the myelin sheath that insulates nerve cells breaks down, leading to problems in the transmission of nervous signals. Symptoms can range from tingling and numbness to tremors, paralysis or blindness. An estimated 2.5 million people around the world suffer from the disease, which is rarely diagnosed before the age of 15....

Wow. Had a doctor's appointment last week for a completely different issue. First thing the doc says is, "the weight loss is great!" That's when I explained that the 30-35 pounds I had lost had all been in the last month or so. That I was constantly thirsty, and "peeing like a race horse." That's when the original reason for the appointment got pushed to the back and that's when life changed. That's when we tested my blood sugar and found it at 297, and shortly after that was when I did my first injection of insulin. Yes, the symptoms...

Father John Corapi gets on a phone in his Montana office and asks someone to boost the volume. The assistant who helped arrange an interview with him had warned about this. “Speak loudly,” she said, “he’s hard of hearing.” Father Corapi himself has never been hard to hear. For nearly two decades, his thundering voice has preached the Gospel with a forceful, meat-and-potatoes theology that’s made him among the most recognizable priests in the world.But since August 2007, that voice has been relatively silent. At first, that was by choice — having traveled more than 2 million miles spreading the...

Vitamin D Tied to Hypertension, Hyperglycemia: Teens with the lowest vitamin D levels had low HDL, metabolic syndrome, and high triglicerides. Low serum levels of vitamin D were linked to increased blood pressure, hyperglycemia, and obesity in an analysis of more than 3,500 American teenagers, a link previously seen in adults. “Vitamin D plays a useful role in general human health. We are just now beginning to understand the role that vitamin D may play in cardiovascular health,” said Dr. Jared P. Reis, who presented a poster on the associations of vitamin D levels and cardiovascular risk factors at a...

SAN DIEGO — The Institute of Medicine is reviewing its 1997 guidelines for vitamin D intake, and will likely recommend increased supplementation when new guidelines are published in 2010. There is a growing consensus that currently recommended intakes—200 IU per day for individuals under age 50 and 400 IU for those aged 50-70—are too low, said Connie Weaver, Ph.D., director of the department of food and nutrition, at Purdue University, West Lafayette, Ind. A recent analysis of data collected by the National Health and Nutrition Examination Survey (NHANES) during 1988-1994 and 2001-2004 even suggests that an epidemic of vitamin D...

Researchers suggest a huge bump in recommended daily levels as the vitamin's benefits extend to helping fight diabetes, cancer and cardiovascular disease. Vitamin D's star is on the rise and physicians who have studied it say it's about time.Recent research has found that higher D levels are beneficial in fighting ills ranging from colds to cancer. And, on March 26, the Institute of Medicine's Food and Nutrition Board began reviewing those studies and many others with an eye to revising the recommended dietary intake of vitamin D and its close companion in maintaining bone health -- calcium. A report is...

CHICAGO – Doctors know some patients needing lifesaving care won't get it in a flu pandemic or other disaster. The gut-wrenching dilemma will be deciding who to let die. Now, an influential group of physicians has drafted a grimly specific list of recommendations for which patients wouldn't be treated. They include the very elderly, seriously hurt trauma victims, severely burned patients and those with severe dementia. The suggested list was compiled by a task force whose members come from prestigious universities, medical groups, the military and government agencies. They include the Department of Homeland Security, the Centers for Disease Control...

Vitamin D supplements may help prevent fractures in people over 65, provided they take enough of the right kind. A new review of clinical trials appears to show a strong dose-dependent effect for vitamin D in lowering the risk for nonvertebral fractures in the elderly. --snip-- The type of vitamin D made a difference. The effect of vitamin D3 was significant, with a 23 percent risk reduction, but there was no significant reduction with vitamin D2. The authors suggest that D3 is more effective in maintaining blood levels of 25-hydroxyvitamin D, the active form that the supplement takes in the...

It used to be that mothers would tell their children, "Go out and play in the sunshine, it's good for you." In more recent years, saying something like that too loudly might have gotten a poor mom arrested and her children taken away from her. "The sun, good for you? Are you crazy? Are you trying to kill your kids with skin cancer?" At least, make sure the urchins are slathered all over in 45 SPF sunscreen, and preferably wearing hats and long sleeves. You might call this the Gospel of St. John the Dermatologist, and it has now been...

A lack of Vitamin D, due to reduced sunlight, has been linked to depression and the symptoms of Seasonal Affective Disorder (SAD), but research by the University of Warwick shows there is no clear link between the levels of vitamin D in the blood and depression. Exposure to sunlight stimulates vitamin D in the skin and a shortage of sunlight in the winter has been put forward as one possible cause of SAD. However Warwick Medical School researchers, led by Dr Oscar Franco, have discovered low levels of vitamin D in the blood may not be connected to depression. The...

WEDNESDAY, March 4 (HealthDay News) -- Many teens today, especially black teens, aren't getting enough of vitamin D, the so-called sunshine vitamin that is essential for cells to function, say researchers from Weill Cornell Medical College in New York City. Vitamin D deficiency has been linked to many chronic diseases, including heart disease, diabetes, immune system problems and inflammatory diseases. "There is evidence that the levels of vitamin D we have been using in the past may have been too low," said lead researcher Dr. Sandy Saintonge, a fellow in general preventive medicine at Weill Cornell. Vitamin D is measured...

People with asthma and other preexisting lung diseases face an especially exaggerated year-round risk from a deficiency Getting plenty of vitamin D — more than diet can offer — appears to provide potent protection against colds, flu and even pneumonia, a new study reports. Although the amount of protection varies by season, the trend is solid: As the amount of vitamin D circulating in blood climbs, risk of upper respiratory tract infections falls. Though that’s not too surprising (SN: 11/11/06, p. 312), the researchers found one unexpected trend: “In people with preexisting lung disease, such as asthma and chronic obstructive...

Multiple sclerosis could be prevented through daily vitamin D supplements, scientists told The Times last night. The first causal link has been established between the “sunshine vitamin” and a gene that increases the risk of MS, raising the possibility that the debilitating auto-immune disease could be eradicated. George Ebers, Professor of Clinical Neurology at the University of Oxford, claimed that there was hard evidence directly relating both genes and the environment to the origins of MS. His work suggests that vitamin D deficiency during pregnancy and childhood may increase the risk of a child developing the disease.

Study finds Parkinson’s patients are more commonly lacking in the vitamin than Alzheimer’s patients or healthy peopleA vitamin D shortage is more likely to show up in people with Parkinson’s disease than in healthy people or those with Alzheimer’s disease, scientists report in the October Archives of Neurology. The study is the most recent contribution to a torrent of findings linking vitamin D deficiency with health risks. It’s well documented that such a deficiency can cause osteoporosis. Studies in recent years have also implicated a shortage of vitamin D in heart disease, stroke, multiple sclerosis, cancer and even respiratory problems....

The nation's leading pediatricians group says children from newborns to teens should get double the usually recommended amount of vitamin D because of evidence that it may help prevent serious diseases. To meet the new recommendation of 400 units daily, millions of children will need to take daily vitamin D supplements, the American Academy of Pediatrics said. That includes breast-fed infants — even those who get some formula, too, and many teens who drink little or no milk. Baby formula contains vitamin D, so infants on formula only generally don't need supplements. However, the academy recommends breast-feeding for at least...

An EU-funded project coordinated by Uppsala University in Sweden will study the origins and significance of lactose tolerance in Europe. The project, called LECHE ('Lactase persistence and the early cultural history of Europe'), is a training network with 13 participating universities in Europe... Approximately 85% of adult northern Europeans are able to digest lactose, a sugar found in milk and other dairy products; however, in the rest of the world the ability to digest milk drops off sharply after infancy. In fact, as one moves south from Scandinavia, lactose tolerance in adulthood drops off. The persistence of lactase (the enzyme...

Low levels of the sunshine vitamin, vitamin D, may contribute to chronic pain among women, scientists believe. The link does not apply to men, suggesting hormones may be involved, according to a study published in the Annals of Rheumatic Diseases said. The team from the Institute of Child Health in London said studies were now needed to see if vitamin D supplements can guard against chronic pain. About one in 10 people are affected by chronic pain at any one time in the UK. The causes are not well understood and much of the focus to date has been on...

Vitamin D Theory of Autism In addition to the current epidemic of vitamin D deficiency, say another epidemic—an epidemic of autism—was upon our children? What if the autism epidemic began at the same time the epidemic of vitamin D deficiency began? What if both epidemics had worsened in unison? What if one theory explained all the unexplained facts about autism? What if both epidemics had the same root cause: sun avoidance? What if both were iatrogenic, that is, medical advice to avoid the sun had caused both epidemics? Be warned, what follows is not light reading—autism is not a...

Vitamin D Linked To Colon Cancer Survival ScienceDaily (June 20, 2008) — Patients diagnosed with colon cancer who had abundant vitamin D in their blood were less likely to die during a follow-up period than those who were deficient in the vitamin, according to a new study by scientists at Dana-Farber Cancer Institute. The findings of the study -- the first to examine the effect of vitamin D among colorectal cancer patients -- merit further research, but it is too early to recommend supplements as a part of treatment, say the investigators from Dana-Farber and the Harvard School of Public...

Get A Little Sun This Summer -- It Could Help Save Your Life, Researcher SuggestsExperts still agree that a fairly modest amount of sun is enough -- perhaps 10-15 minutes of exposure on your arms and face about three times a week. Sunburn should of course be avoided and a tan clearly isn't necessary -- but some real sun exposure probably is. (Credit: iStockphoto/Robert Churchill) ScienceDaily (Jun. 18, 2008) — As summer comes and people across America get ready to start slathering on the sunscreen, a note of caution is in order – a little sunshine is good for you....

Men With Vitamin D Deficiency May Have Increased Risk Of Heart Attack ScienceDaily (Jun. 11, 2008) — Low levels of vitamin D appear to be associated with higher risk of myocardial infarction (heart attack) in men, according to a new report. Studies have shown that the rates of cardiovascular disease-related deaths are increased at higher latitudes and during the winter months and are lower at high altitudes, according to background information in the article. "This pattern is consistent with an adverse effect of hypovitaminosis D [vitamin D deficiency], which is more prevalent at higher latitudes, during the winter and at...

Men with low levels of vitamin D have an elevated risk for a heart attack, researchers said on Monday in the latest study to identify important possible health benefits from the "sunshine vitamin." In the study, men classified as deficient in vitamin D were about 2 1/2 times more likely to have a heart attack than those with higher levels of the vitamin. "Those with low vitamin D, on top of just being at higher risk for heart attack in general, were at particularly high risk to have a fatal heart attack," study author Dr. Edward Giovannucci of the Harvard...

AP Medical Writer Breast cancer patients with low levels of vitamin D were much more likely to die of the disease or have it spread than patients getting enough of the nutrient, a study found - adding to evidence the "sunshine vitamin" has anti-cancer benefits. The results are sure to renew arguments about whether a little more sunshine is a good thing. The skin makes vitamin D from ultraviolet light. Too much sunlight can raise the risk of skin cancer, but small amounts - 15 minutes or so a few times a week without sunscreen - may be beneficial, many...

Vitamin D supplementation for high risk groups may be warrantedIn a definitive critical review, scientists at Children’s Hospital & Research Center Oakland ask whether there is convincing biological or behavioral evidence linking vitamin D deficiency to brain dysfunction. Joyce C. McCann, Ph.D., assistant staff scientist and Bruce N. Ames, Ph.D., senior scientist at Children’s Hospital Oakland Research Institute (CHORI) conclude that there is ample biological evidence to suggest an important role for vitamin D in brain development and function, and that supplementation for groups chronically low in vitamin D is warranted. Their conclusions will be published on April 22, 2008...

Vitamin D Deficiency May Be To Blame For Soft Bones In Baby's Skull ScienceDaily (Mar. 28, 2008) — Softening of the skull bones in normal-looking babies might reflect vitamin D deficiency during pregnancy, according to a new study. Furthermore, breast-feeding without vitamin D supplementation could prolong the deficiency, which might lead to a risk of serious health problems later in life, including type 1 diabetes and decreased bone density. “Craniotabes, the softening of skull bones, in otherwise normal newborns has largely been regarded as a physiological condition without the need for treatment,” said Dr. Tohru Yorifuji, of Kyoto University Hospital...

Extra Vitamin D In Early Childhood Cuts Adult Diabetes Risk ScienceDaily (Mar. 13, 2008) — Vitamin D supplements in early childhood may ward off the development of type 1 diabetes in later life, reveals a research review published ahead of print in the Archives of Disease in Childhood. Type 1 diabetes is an autoimmune disorder, in which insulin producing beta cells in the pancreas are destroyed by the body's own immune system, starting in early infancy. The disease is most common among people of European descent, with around 2 million Europeans and North Americans affected. Its incidence is rising at...

The claims have been sensational. Martin Mittelstaedt checks up on the research behind the hypeIn the summer of 1974, brothers Frank and Cedric Garland had a heretical brainwave. The young epidemiologists were watching a presentation on death rates from cancer county by county across the United States. As they sat in a lecture hall at Johns Hopkins University in Baltimore looking at the colour-coded cancer maps, they noticed a striking pattern, with the map for colon cancer the most pronounced. Counties with high death rates were red; those with low rates were blue. Oddly, the nation was almost neatly divided...

Vitamin D Deficiency Study Raises New Questions About Disease And Supplements ScienceDaily (Jan. 27, 2008) — Low blood levels of vitamin D have long been associated with disease, and the assumption has been that vitamin D supplements may protect against disease. However, this new research demonstrates that ingested vitamin D is immunosuppressive and that low blood levels of vitamin D may be actually a result of the disease process. Supplementation may make the disease worse. In a new report Trevor Marshall, Ph.D., professor at Australia’s Murdoch University School of Biological Medicine and Biotechnology, explains how increased vitamin D intake affects...

Lack Of Vitamin D May Increase Heart Disease Risk ScienceDaily (Jan. 8, 2008) — The same vitamin D deficiency that can result in weak bones now has been associated with an increased risk of cardiovascular disease, Framingham Heart Study researchers report in Circulation: Journal of the American Heart Association. "Vitamin D deficiency is associated with increased cardiovascular risk, above and beyond established cardiovascular risk factors," said Thomas J. Wang, M.D., assistant professor of medicine at Harvard Medical School in Boston, Mass. "The higher risk associated with vitamin D deficiency was particularly evident among individuals with high blood pressure." In a...

Pregnant or breastfeeding women have been urged to boost their vitamin D intake amid warnings that cases of rickets in children are increasing. Rickets is a bone disease mainly caused by a lack of the vitamin. It can lead to deformities, stunted growth and general ill-health. Some minority ethnic groups in the UK, including Asians, are particularly at risk, says the Department of Health. Doctors want pregnant women to take more vitamin D during winter months. It is made by the skin in response to sunlight, but can also be found in certain foods. Officials are urging women to check...

A team of researchers led by National Cancer Institute (NCI) epidemiologist Dr. Michal Freedman has published an article suggesting that vitamin D is highly successful in reducing deaths from cancers of the colon and rectum. The researchers studied 16,818 people who had joined a nationwide U.S. government health survey between 1988 and 1994. The volunteers were then followed through the year 2000, by which time 536 had died of cancer. The study found that people with relatively high blood levels of vitamin D when they entered the study had a 72 percent reduction in their risk of dying of colorectal...
