The latest research: Vitamin D for prevention of respiratory infections March 23, 2013 -- John Cannell, MD Respiratory tract infection involves a large number of infectious diseases in the respiratory tract. They are split into upper respiratory tract infections (URTI) or lower respiratory tract infections (LRTI). LRTI, such as pneumonia, tend to be far more serious conditions than URTI, such as the common cold. Typical symptoms of URTI include tonsillitis, sore throat, laryngitis, sinusitis, ear infections, and the common cold. Symptoms of URTI can include cough, sore throat, runny nose, nasal congestion, headache, low grade fever, facial pain or pressure and sneezing. LRTI are much more serious and are the leading cause of death among all infectious diseases. The two most common types are bronchitis and pneumonia. Cough, chest pain and fever are the common symptoms. Influenza infections affects both the upper and lower respiratory tracts, but the much more dangerous strains, such as H1N1, infects deep into the lower lungs causing severe symptoms. Besides cough and fever, prostration (having to lie down) is a prominent symptom of a true influenza infection. An H1N1 influenza strain killed up to 50,000,000 people in 1918 and 1919, and, for unknown reasons, was especially fatal for young people in the prime of life. Recently, Dr Jaykaran Charan and colleagues of the Indian Institute of Public Health published a meta-analysis of all randomized controlled trials of vitamin D and respiratory tract infections.

Take a look at this presentation made by Andre Tomlin at the Cochrane UK & Ireland 21st Anniversary Symposium discussing social media and disseminating helpful conversation to influence practice. Help the Council Today Like Tweet Forward to Friend Copyright © 2013 The Vitamin D Council, So much information to pass along. I intend to blog more often when I see a interesting isolated study. I will continue to blog on Tuesdays with the News Letter when it comes out. I only plan a general mailing for the news letter. There is a RSS feed available though, if you want to make use of it.
Todays news letter. They are seeing a correlation between low vitamin D levels and esophageal cancer. In this country, it tends to be predominantly a disease of Aftrican Americans. They do run a much lower average vitamin D level than Caucasians. Also, it is reported, they found a correlation of lower Blood pressure readings in those African Americans who have higher vitamin D levels. Good news for the hypertensive black man. Apparently they have done a study in Germany that says optimization of the vitamin D levels in Asthmatics reduces the severity the problem. I have seen evidence of this for years with co workers who have Asthma and did optimized their vitamin D. So not surprised by this at all. Several had no problem, after optimization, and others where able to use less medicine to control asthma. All improved, in my experience and continue to do so as long as they keep their level up. I do get to see a quite a few people who have followed the optimized route with vitamin D since 2004. One more thing. I read years ago there was a lot of esophageal cancer in China. There is was correlated with the ingestion of cured nitrate meat. Something that should only be ingested rarely and certainly not daily, imho. Finally a expo is occurring in California on vitamin D. Anyone in the area can take advantage of it. Also there was a webinar today and it should be available on video at the website listed. Grass Roots Health is a valuable resource for those are interested in even more information. They sponsored the webinar and are very active with seminars and blood testing. Now for the news letter. Sun exposure and esophageal cancer: Does vitamin D help? March 16, 2013 -- John Cannell, MD Esophageal cancer is a relatively rare form of cancer, but some areas of the world have a markedly higher incidence than others: such as Belgium, China, Iran, Iceland, India, Japan, and the United Kingdom. The American Cancer Society estimates that just over 15 thousand cases of esophageal cancer are diagnosed in the United States every year. In the United States, squamous cell carcinoma of the esophagus usually affects African Americans. The incidence of esophageal adenocarcinoma has been rising relatively rapidly over the last four decades. Humans cannot be evolving quickly enough for genetics to explain this rapid change. Instead, this indicates that environmental or behavioral factors have important roles in the etiology of the cancer. Such general evidence might make one ask, does vitamin D have a role? Recently, Dr Joel Rubenstein of the University of Michigan Medical School wrote an editorial opining that while the vitamin D hypothesis is attractive, vitamin D should not be used to prevent esophageal cancer. Rubenstein JH. Editorial: shedding some light on the etiology of adenocarcinomas of the esophagus and gastric cardia. Am J Gastroenterol. 2012 Dec;107(12):1814-6. He pointed out that an ecological analysis found that counties in the United States with lower UVR exposure had greater incidences and mortality of esophageal cancer. However, ecological analyses are prone to biases called the “ecological fallacy,” because individual level data may differ from the population level data.

Prostate cancer and health disparities March 19, 2013 -- Vitamin D Event This week's free Grassroots Health webinar features Dr Bruce Hollis discussing vitamin D, prostate cancer, and health disparities. Register here for today's webinar, which starts at 10am PST! Have a vitamin D question? You can submit your questions for Dr Heaney when you register. A quick reminder. To negate most of the disabilities due to living in civilization you need to address what causes inflammation and disease in your body. Decrease inflammation and you decrease disease and positively affect your longevity and quality of life no matter your age. So, optimize your vitamin D. The higher the level the less inflammation. Take magnesium if you don't have a well from which you get your water. exception is those being treated for atrial fibrillation and use of anti coagulants like coumadin. Converting vitamin D to the pro hormone uses magnesium so your level will fall from a probably low level that existed already. There is no good test for magnesium. Most doc's don't know this. Take vitamin K2 either in pill form or by using fermented foods daily. Yoghurt is not high enough in colony count. Do not take k2 without a doc's supervision if you are on anti coagulants. Vitamin k2 directs calcium to your bones and not to your arteries. One study showed it cleaned out fifty percent of calcium in your arteries in six months. Look at the studies...tell your health provider.
Now the VDC news letter Vitamin D Newsletter - March 12, 2013 View this email in your browser Supporters of the Vitamin D Council What's with the USPSTF report? March 8, 2013 -- Brant Cebulla We have received many emails regarding the calcium, vitamin D and fracture report from the United States Preventative Services Task Force, often just abbreviated the USPSTF. The USPSTF is a panel of physicians and epidemiologists appointed by the US Department of Health and Human Services. They publish recommendations for a variety of different things after evaluating the effectiveness of interventions, screening and other clinical practices. Usually, the USPSTF publishes a draft for the public to read. They then open up a one month grace period for the public to comment before they release a finalized recommendation six months later. When their recent evaluation and recommendation hit headlines last week that vitamin D and calcium cannot prevent fractures, this was actually the same report that hit headlines around June/July 2012. Our Executive Director Dr Cannell responded to the draft then and what he stated then still echoes our opinions of now. Their report is based on data from two systematic reviews and a meta-analysis. They stated the following:
On the other hand, the second contention that vitamin D of intakes of greater than 400 IU have not been tested enough to determine its effect on fractures is disputed. In fact, Professor Bischoff-Ferrari pooled 11 randomized controlled trials and determined that intakes of 800 IU of vitamin D and greater likely reduce fracture incidence, while lower intakes do not.

Although you'll be without vitamin D news and blogs for a few hours, don't worry it will be worth the wait! Why test? March 12, 2013 -- Vitamin D Event This week's free Grassroots Health webinar features Dr Robert Heaney discussing the question: "Why test vitamin D?!" Register here for today's webinar, which starts at 10am PST! Have a vitamin D question? You can submit your questions for Dr Heaney when you register. What is the upper limit and NOAEL and are they justified? February 26, 2013 -- John Cannell, MD The upper limit (UL) for vitamin D, set by the 2011 Food and Nutrition Board, is 4,000 IU per day. This is defined as the highest level of daily consumption that causes no side effects in humans when used indefinitely without medical supervision. The same board set the No Observed Adverse Effects Level (NOAEL) at 10,000 IU/day. The NOAEL is the dose at which there are no published studies showing any adverse effects of that dosage. As an aside, if there are any studies showing 20,000 IU/day is unsafe, I would like to see them. Anyway, the Upper Limit is simply calculated from the NOAEL by dividing by a safety factor. In vitamin D’s case, they divided the NOAEL of 10,000 IU/day by 2.5 to get the Upper Limit of 4,000 IU/day. At the Vitamin D Council, we recommend that patients exceed the Upper Limit, but not exceed the NOAEL of 10,000 IU/day, unless they are under medical supervision or know what they are doing. But why do we recommend more than the Food and Nutrition Board’s Upper Limit? Because the question is, will 4,000 IU/day get 97.5% of the population above a certain 25(OH)D threshold, such as 30 ng/ml? Or are doses higher than 4,000 IU/day needed to achieve blood levels above 30 ng/ml, 30 ng/ml still being much lower than average 25(OH)D levels found in hunter gatherers living around the equator, which are about 46 ng/ml. Vitamin D status in indigenous populations: Part 1 Posted on August 27, 2012 by John Cannell, MD Doctor Etienne Cavalier and colleagues of the University of Liège in Belgium recently tried to find out if 4,000 IU/day is enough by giving large or stoss doses to a total of 140 subjects.
