    Association between serum 25(OH)D concentrations and bone stress fractures in Finnish young men. Ruohola JP, Laaksi I, Ylikomi T, Haataja R, Mattila VM, Sahi T, Tuohimaa P, Pihlajamäki H. J Bone Miner Res. 2006 Sep;21(9):1483-8. doi: 10.1359/jbmr.060607 Conclusions: A lower level of serum 25(OH)D concentration may be a generally predisposing element for bone stress fractures. Considering the obvious need of additional vitamin D in prevention of stress fractures, the effects of vitamin D fortification of foods and supplementation will be subjects of interest for future research PMID: 16939407

JNNP -- eLetters for Soilu-Hänninen et al., 79 (2) 152-157 - 0 views

    Vitamin D may suppress infections which lead to development of Multiple Sclerosis Steven R Brenner, None (16 August 2007) J Neurol Neurosurg Psychiatry 2008 I read the article with reference to the inverse relationship between multiple sclerosis clinical activity and deficiency of vitamin D by Soilu-Hannienen (1) with interest, and was considering what mechanism could be in play to cause such a relationship. 25-hydroxylated metabolites of vitamin D act as intracellular regulators of the synthesis and action of defensin (2) molecules against bacterial antigens, defensin being an endogenously synthesized antimicrobial substance (2). Human cathelicidin antimicrobial peptide gene is a target of vitamin D receptor and is strongly up-regulated by 1,25-dihydroxyvitamin D3, indicating vitamin D receptor and the 1,25-dihydroxyvitaminD3 regulate primate innate immunity (3)

Researchers who touted high vitamin D doses shut out of panel - The Globe and Mail - 0 views

  •  
    The panel selected to analyze the health claims is being criticized for not including the medical researchers whose work prompted intense scientific interest in the nutrient in the first place. "If you were publicly in favour of vitamin D, you were not included, and I find that outrageous," said Reinhold Vieth, a professor in the department of nutritional sciences at the University of Toronto, and one of Canada's leading experts on the nutrient.

Basic Nutrition: The Miracle of Vitamin D - 0 views

  •  
    In April of 2000 a clinical observation published in Archives of Internal Medicine caught my attention. Dr. Anu Prabhala and his colleagues reported on the treatment of five patients confined to wheelchairs with severe weakness and fatigue. Blood tests revealed that all suffered from severe vitamin D deficiency. The patients received 50,000 IU vitamin D per week and all became mobile within six weeks.1\n\nDr. Prabhala's research sparked my interest and led to a search for current information on vitamin D, how it works, how much we really need and how we get it. The following is a small part of the important information that I found.

The Vitamin D-Antimicrobial Peptide Pathway and Its Role in Protection Against Infectio... - 0 views

    The vitamin D-antimicrobial peptide pathway and its role in protection against infection. Gombart AF. Future Microbiol. 2009 Nov;4:1151-65. PMID: 19895218 Vitamin D deficiency has been correlated with increased rates of infection. Since the early 19th century, both environmental (i.e., sunlight) and dietary sources (cod liver) of vitamin D have been identified as treatments for TB. The recent discovery that vitamin D induces antimicrobial peptide gene expression explains, in part, the 'antibiotic' effect of vitamin D and has greatly renewed interest in the ability of vitamin D to improve immune function. Subsequent work indicates that this regulation is biologically important for the response of the innate immune system to wounds and infection and that deficiency may lead to suboptimal responses toward bacterial and viral infections. The regulation of the cathelicidin antimicrobial peptide gene is a human/primate-specific adaptation and is not conserved in other mammals. The capacity of the vitamin D receptor to act as a high-affinity receptor for vitamin D and a low-affinity receptor for secondary bile acids and potentially other novel nutritional compounds suggests that the evolutionary selection to place the cathelicidin gene under control of the vitamin D receptor allows for its regulation under both endocrine and xenobiotic response systems. Future studies in both humans and humanized mouse models will elucidate the importance of this regulation and lead to the development of potential therapeutic applications

Free The Animal - 1 views

  •  
    After much consideration into this blog's new name in the light of my new direction, the decision has been made. "Free the Animal" Why? First, if you read that post linked above, you know that my health and fitness approach is perfectly in harmony with my philosophical approach; and hence, my approach to politics and all that. In other words, a big part of the reason I have discovered something that truly works; and moreover, is the simplest, most natural, downright fun way of living: that gets you lean and fit; gets you feeling and sleeping great; and gets you looking years and years younger is precisely because I don't believe in the gods of heaven or earth, we evolved over millions of years and are conditioned by survival pressures that in no way include all vegetable diets, gorging on bottled water all day, eating ground grass seeds (grains and derivatives) running on a treadmill or elliptical, or involving ourselves in social schemes and cons that leave us powerless, with no influence, and at the mercy of the crowd and collective (the cannibal pot). Some have a lot of the pieces and do good work. I have all of the major pieces, though acquiring all of the specifics is a lifelong and never-ending journey of discovery. I will focus on essentials and specifics that really matter to me and others living a normal life in pursuit of survival, prosperity and happiness. I will point to other sources that provide more depth in specific areas that are of interest to only some

VitaminD3 - Ted Hutchinson's blog - 0 views

  •  
    "Thursday, 17 December 2009 This blog is in response to Dr Briffa's post here. as I keep having problems commenting on his blogs. While 44ng/ml is sufficient to not only maximize uptake of calcium (>32ng/ml) and ensure maximum bone mineral density (>42ng/ml), pregnant and nursing mothers should be aware that in order to maximize the amount of vitamin D3 in human breast milk 6400iu/daily was found to be necessary to raise (>58ng/ml) at latitude 32. This is detailed in the Taylor, Wagner and Hollis paper. Vitamin D supplementation during lactation to support infant and mother. Although 4000iu/daily met the mothers daily needs in full it left babies being born with lower 25(OH)D status than required for optimum calcium absorption They also found DAILY use of supplements was required by pregnant and nursing mothers to ensure an even daily Vitamin D3 supply to the foetus & baby. It makes virtually no measurable difference for everyone else if you supplement daily or weekly. While Dr Briffa will not be lactating he may be interested seeing in the Grassrootshealth chart showing disease incidence by 25(OH)D status. this may encourage him to go just another 10ng/ml higher and a bit nearer to the natural level at which human breast milk flows replete with D3."
