  • Scientists Blow The Lid on Cancer & Sunscreen Myth

    According to a June 2014 article featured in The Independent (UK), a major study conducted by researchers at the Karolinska Institute in Sweden found that women who avoid sunbathing during the summer are twice as likely to die as those who sunbathe every day. The epidemiological study followed 30,000 women for over 20 years and “showed that mortality was about double in women who avoided sun exposure compared to the highest exposure group.” Researchers concluded that the conventional dogma, which advises avoiding the sun at all costs and slathering on sunscreen to minimize sun exposure, is doing more harm than...

    We've seen promising moves towards developing a universal or near-universal influenza vaccine, but researchers at the Donald P. Shiley BioScience Center have taken a different tack to ward of the crafty virus. Although the flu virus actively keeps the immune system from detecting it for a few days, giving it time to gain a foothold, the researchers have found that a powerful synthetic protein, known as EP67, can kick start the immune system so that it reacts almost immediately to all strains of the virus. Previously, EP67 had primarily been used to help activate the immune response by being added...

As a child, I was allergic to milk and was raised on soybean formula. I practically lived outside and took jobs, like bean row walking and picking tomatoes. I did not start suffering from OCD until I started working in factories and restaurants. I spent a few years farming, and the OCD ebbed. Next I started trucking and worked in confinement hog buildings. I did a total tailspin and the OCD...

    Another day, and another vitamin has failed to live up to all of its hype. This time it’s vitamin D. The reality check is coming from two new research reviews published in the Annals of Internal Medicine. The reviews, which looked at hundreds of previous studies of the “sunshine vitamin,” conclude that there’s little evidence that vitamin D protects against cancer or heart disease. They also show that vitamin D doesn’t prevent fractures when it’s taken alone. Pairing vitamin D with extra calcium does appear to help prevent broken bones in the elderly, however. “For many years, the enthusiasm for...

UK and Canadian scientists identified the mutated gene in 35 parents of a child with MS and, in each case, the child inherited it. Researchers say this adds weight to suggestions of a link between vitamin D deficiency and MS. The study is in Annals of Neurology. Multiple sclerosis is an inflammatory disease of the central nervous system (the brain and spinal cord). Although the cause of MS is not yet conclusively known, both genetic and...

When consumed, numerous metabolic forms of D2 can be traced in the body.

A new monograph suggests that Mozart died from too little sunlight. The researchers give us a simple theory. When exposed to sunlight, people's skin naturally produces vitamin D. Mozart, toward the end of his life, was nearly as nocturnal as a vampire, so his skin probably produced very...

"Since vitamin D is generally lower in persons with obesity, it is possible that low vitamin D could account, in part, for the link between obesity and diseases such as cancer, heart disease and diabetes," said Caitlin Mason, Ph.D., lead author of...

    Having low vitamin D levels may increase a person's risk of developing Parkinson's disease later in life, say Finnish researchers. Their study of 3,000 people, published in Archives of Neurology, found people with the lowest levels of the sunshine vitamin had a three-fold higher risk. Vitamin D could be helping to protect the nerve cells gradually lost by people with the disease, experts say. The charity Parkinson's UK said further research was required. Parkinson's disease affects several parts of the brain, leading to symptoms like tremor and slow movements. 30-year study The researchers from Finland's National Institute for Health and...

    ATS 2011, DENVER – Vitamin D supplements may help patients with chronic obstructive pulmonary disease (COPD) get more from their pulmonary rehabilitation programs, according to a study conducted by researchers from Belgium. The study results will be presented at the ATS 2011 International Conference in Denver. "Our study shows that high doses of vitamin D supplementation on top of a standard rehabilitation program improve the outcome in terms of exercise capacity and respiratory muscle strength," said Miek Hornikx, physiotherapist and doctoral student in the department of pneumology at the Katholieke Universiteit Leuven in Leuven, Belgium. Vitamin D deficiency is common...

    Abstract The association is not clear-cut, according to an assessment of data from the Third National Health and Nutritional Examination Survey. Introduction Ultraviolet radiation has various deleterious effects but a positive influence on vitamin D metabolism. Dermatologists typically recommend that patients use sunscreen and take other precautions to prevent sunburn, nonmelanoma skin cancer, melanoma, and cutaneous photoaging. This practice is increasingly being scrutinized because much of the population is vitamin D deficient and because several healthful effects have been attributed to vitamin D, including a potential cancer-protection effect. To assess the association between baseline serum 25-hydroxyvitamin D levels (25[OH]D) and...

    A new study published in the journal Respirology reveals that adult patients admitted to the hospital with pneumonia are more likely to die if they have Vitamin D deficiency. Vitamin D is known to be involved in the innate immune response to infection. The team of researchers at Waikato Hospital and the Universities of Waikato and Otago, measured vitamin D in the blood samples of 112 adult patients admitted with community acquired pneumonia during the winter at the only acute-care hospital in Hamilton, New Zealand. The researchers found that Vitamin D deficiency was associated with higher mortality within the first...

    News tips from the 2011 Annual Meeting of the Pediatric Academic Societies, April 30-May 3, Denver, Colo.Pediatricians from Johns Hopkins Children's Center and elsewhere have discovered a link between low levels of vitamin D and anemia in children. The findings, presented on May 1 at the annual meeting of the Pediatric Academic Societies in Denver, Colo., show that vitamin D deficiency may play an important role in anemia. Anemia, which occurs when the body has too few oxygen-carrying red blood cells, is diagnosed and tracked by measuring hemoglobin levels. Symptoms of mild anemia include fatigue, lightheadedness and low energy. Severe...

    High levels of vitamin D in the bloodstream appear to be associated with a decreased risk of developing early age-related macular degeneration among women younger than 75 years, according to a report in the April issue of Archives of Ophthalmology, one of the JAMA/Archives journals. "Age-related macular degeneration (AMD), a chronic, late-onset disease that results in degeneration of the macula, is the leading cause of adult irreversible vision loss in developed countries," the authors write as background information in the article. "Age-related macular degeneration affects approximately 9 percent (8.5 million) of Americans aged 40 years and older." Amy E. Millen,...

    Researchers say their mice study should provide a word of caution to people who believe that excess vitamin D prevents cancerOrlando, Fla. -- In mice models of breast cancer, researchers at the Georgetown Lombardi Comprehensive Cancer Center, a part of Georgetown University Medical Center, found that vitamin D significantly reduced development of estrogen receptor-positive (ER+) breast cancer both in lean and obese mice, but had no beneficial effect in estrogen receptor-negative (ER-) cancer. In fact, obese mice destined to develop ER- breast cancer were clearly worse off than lean ER- mice if they were given vitamin D in their diet....

    A lack of vitamin D, even in generally healthy people, is linked with stiffer arteries and an inability of blood vessels to relax, research from the Emory/Georgia Tech Predictive Health Institute has found. The results add to evidence that lack of vitamin D can lead to impaired vascular health, contributing to high blood pressure and the risk of cardiovascular disease. Study participants who increased their vitamin D levels were able to improve vascular health and lower their blood pressure. The data is being presented on Sunday by Ibhar Al Mheid, MD, a cardiovascular researcher at Emory University School of Medicine,...

    [PRESS RELEASE, 9 March 2011] A study from Karolinska Institutet has shown that the body's ability to break down medicines may be closely related to exposure to sunlight, and thus may vary with the seasons. The findings offer a completely new model to explain individual differences in the effects of drugs, and how the surroundings can influence the body's ability to deal with toxins. The study will be published in the scientific journal Drug Metabolism & Disposition and is based on nearly 70,000 analyses from patients who have undergone regular monitoring of the levels of drugs in their blood. The...

    U-M researchers find high levels of enzyme that blocks vitamin D can predict lung cancer survivalANN ARBOR, Mich. — Recent research suggests vitamin D may be able to stop or prevent cancer. Now, a new study finds an enzyme that plays a role in metabolizing vitamin D can predict lung cancer survival. The study, from researchers at the University of Michigan Comprehensive Cancer Center, suggests that this enzyme stops the anti-cancer effects of vitamin D. Levels of the enzyme, called CYP24A1, were elevated as much as 50 times in lung adenocarcinoma compared with normal lung tissue. The higher the level...
