February 24, 2011 ─ (BRONX, NY) ─ A study of more than 3,000 children shows that low vitamin D levels are associated with increased likelihood that children will develop allergies, according to a paper published in the February 17 online edition of the Journal of Allergy and Clinical Immunology. Researchers from Albert Einstein College of Medicine of Yeshiva University headed the study. Researchers looked at the serum vitamin D levels in blood collected in 2005-2006 from a nationally representative sample of more than 3,100 children and adolescents and 3,400 adults. The samples are derived from the National Health and Nutrition...

With most people unable to get enough vitamin D from sunlight or foods, scientists are suggesting that a new vitamin D-fortified food — bread made with high-vitamin D yeast — could fill that gap. Their study, confirming that the approach works in laboratory tests, appears in ACS' Journal of Agricultural and Food Chemistry. Connie Weaver and colleagues cite studies suggesting that up to 7 in 10 people in the United States may not get enough vitamin D, which enables the body to absorb calcium. Far from just contributing to healthy bones, however, vitamin D seems to have body-wide beneficial effects....

Researchers at the University of California, San Diego School of Medicine and Creighton University School of Medicine in Omaha have reported that markedly higher intake of vitamin D is needed to reach blood levels that can prevent or markedly cut the incidence of breast cancer and several other major diseases than had been originally thought. The findings are published February 21 in the journal Anticancer Research While these levels are higher than traditional intakes, they are largely in a range deemed safe for daily use in a December 2010 report from the National Academy of Sciences Institute of Medicine. "We...

Gov't Research Also Shows Them Much Higher in Vitamin D; Dietitian: Credit Healthier Animal Feed, in Part(CBS) If you like eggs, this is good news: A new government study finds they're actually 14 percent lower in cholesterol and 64 percent higher in vitamin D than previously thought. Registered Dietitian Cynthia Sass stopped by the "The Early Show" Tuesday to explain what this may mean for your health. What caused this change in cholesterol and vitamin D levels? Sass, the author of "Cinch!: Conquer Cravings, Drop Pounds, and Lose Inches," told "Early Show" co-anchor Chris Wragge the saying "You are what...

CINCINNATI—A new study shows that vitamin D deficiency could be linked to the development and severity of certain autoimmune lung diseases. These findings are being reported in the Jan. 4 edition of the journal Chest. Brent Kinder, MD, UC Health pulmonologist, director of the Interstitial Lung Disease Center at the University of Cincinnati and lead investigator on the study, says vitamin D deficiencies have been found to affect the development of other autoimmune diseases, like lupus and type 1 diabetes. "We wanted to see if lack of sufficient vitamin D would also be seen in patients who are diagnosed with...

Most Americans and Canadians up to age 70 need no more than 600 international units (IUs) of vitamin D per day to maintain health, and those 71 and older may need as much as 800 IUs, says a new report from the Institute of Medicine. The amount of calcium needed ranges, based on age, from 700 to 1,300 milligrams per day... > A large amount of evidence, which formed the basis of the new intake values, confirms the roles of calcium and vitamin D in promoting skeletal growth and maintenance and the amounts needed to avoid poor bone health. >...

Supplementation with the 'sunshine vitamin' may reduce risk of diabetes and heart disease(SACRAMENTO, Calif.) ― Researchers from the UC Davis Health System have found that compared with healthy controls, blood levels of vitamin D are significantly reduced in patients in the Sacramento area with metabolic syndrome, a constellation of disease risk factors that affects about one in three U.S. adults and predisposes them to diabetes, heart disease and stroke. The study is the first to examine vitamin-D status in patients with metabolic syndrome living in Northern California, where the many hours of sunshine make the vitamin-D deficiency finding surprising. The...

Megadoses of 'sunshine vitamin' don't prevent disease, may be harmful WASHINGTON — For the past few years vitamin D has been the "it" vitamin, with studies wildly trumpeting the supplement's role in strengthening bones, reducing the risk of some cancers, heart disease, along with fighting autoimmune diseases and diabetes. But long-awaited new dietary guidelines say there's no proof that megadoses of the "sunshine vitamin" prevent cancer, diabetes or other conditions. While some people will need a bit more vitamin D than they're already getting, some studies suggest that too much could actually cause some kinds of cancer, according to the...

WASHINGTON (AFP) – Vitamin D and calcium have been hailed as a possible antidote for cancer, heart disease and more, but a panel of US and Canadian doctors said Tuesday that the duo's only sure benefit is bone health. After reviewing about 1,000 studies on the supposed links between low vitamin D levels and higher risk of serious diseases, the panel concluded that they showed inconsistent results, sometimes due to shoddy research methods. The experts also issued new guidelines -- the first since 1997 -- for North Americans, saying people should take between 700 and 1,300 milligrams of calcium and...

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. Michael Holick...

Supplementation Is Safe and Effective. DR. HEANEY is John A. Creighton University Professor and professor of medicine in the division of endocrinology at Creighton University in Omaha, Neb. He was a member of the Institute of Medicine's Calcium and Related Nutrients Panel of the Food and Nutrition Board, which set the intake recommendations for vitamin D in 1997. He reports no financial disclosures.Widespread supplementation of the adult population with vitamin D is advisable because it restores the conditions under which human physiology evolved, and because it is efficacious and safe.Let's look first at the physiology. Vitamin D is normally made in...

PITTSBURGH, Aug. 25 – Vitamin D may be an effective therapy to treat and even prevent allergy to a common mold that can cause severe complications for patients with cystic fibrosis and asthma, according to researchers from Children's Hospital of Pittsburgh of UPMC, the University of Pittsburgh School of Medicine and Louisiana State University School of Medicine. Results of the study, led by Jay Kolls, M.D., Ph.D., a lung disease researcher at Children's Hospital and professor of pediatrics at the University of Pittsburgh School of Medicine, are published in the September 2010 issue of the Journal of Clinical Investigation. Aspergillus...

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...

Vitamin D expert Anthony Norman recommends a daily intake of 2000 international units for most adultsRIVERSIDE, Calif. – Vitamin D surfaces as a news topic every few months. How much daily vitamin D should a person get? Is it possible to have too much of it? Is exposure to the sun, which is the body's natural way of producing vitamin D, the best option? Or do supplements suffice? In the July 2010 issue of Endocrine Today, a monthly newspaper published by SLACK, Inc., to disseminate information about diabetes and endocrine disorders, Anthony Norman, a distinguished professor emeritus of biochemistry and...

Physicians say Canadians should be taking more supplementsNew and updated guidelines on recommended vitamin D intake have been published this week in the online issue of the Canadian Medical Association Journal (CMAJ). Dr. David Hanley, professor at the University of Calgary Faculty of Medicine, and member of Osteoporosis Canada's (OC) Scientific Advisory Council, is the lead author of the paper on behalf of Osteoporosis Canada. "OC's current recommendations on vitamin D intake for Canadians are more than 10 years old, and since then, there has been a lot of new and exciting research in this area," says Hanley, who is...

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...

A pair of new studies has uncovered evidence that low levels of vitamin D could lead to poor blood sugar control among diabetics and increase the risk of developing metabolic syndrome among seniors. ..... More than 90 percent of the patients, who ranged in age from 36 to 89, had either vitamin D deficiency or insufficiency, the authors found, despite the fact that they all had had routine primary care visits before their specialty visit. Just about 6 percent of the patients were taking a vitamin D supplement at the time of their visit, the research team noted, and those...

At a time when consumer interest in health-enhancing foods is high, Agricultural Research Service (ARS)-funded scientists have contributed to a limited but growing body of evidence of a link between vitamin D and cognitive function. Cognitive function is measured by the level at which the brain is able to manage and use available information for activities of daily life. Alzheimer's disease, the most common form of age-related dementia, affects about 47 percent of adults aged 85 years or older in the United States. Identifying nutritional factors that lower cognitive dysfunction and help preserve independent living provides economic and public health...
