    Optimal vitamin D status attenuates the age-associated increase in systolic blood pressure in white Americans: results from the third National Health and Nutrition Examination Survey. Judd SE, Nanes MS, Ziegler TR, Wilson PW, Tangpricha V. Am J Clin Nutr. 2008 Jan;87(1):136-41. PMID: 18175747 Conclusions: SBP is inversely associated with serum vitamin D concentrations in nonhypertensive white persons in the United States. This observation provides a rationale for studies on the potential effects of vitamin D supplementation as a method to reduce SBP in persons at risk of hypertension.

    Low serum 25-hydroxyvitamin D concentrations and secondary hyperparathyroidism in middle-aged white strict vegetarians. Lamberg-Allardt C, Kärkkäinen M, Seppänen R, Biström H. Am J Clin Nutr. 1993 Nov;58(5):684-9. PMID: 8237875 In conclusion, white strict vegetarians are at risk of vitamin D deficiency, at least in the winter, primarily because of a low dietary vitamin D intake, despite a normal sunlight exposure in summer. Low serum 25(OH)D concentrations are accompanied by high S-iPTH concentrations, which also are affected by a low calcium intake. The effect of these changes on bone health remains to be evaluated.

White Europeans evolved only '5,500 years ago' - Times Online - 0 views

  •  
    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.

    Dietary recommendations for vitamin D: a critical need for functional end points to establish an estimated average requirement. Whiting SJ, Calvo MS. J Nutr. 2005 Feb;135(2):304-9. Review. PMID: 15671232 In summary, vitamin D has emerged as a critical nutrient for which there is a compelling health need to establish adequate dietary guidelines in North America and worldwide given the increasing evidence of vitamin D deficiency and insufficient links to risk of chronic disease. We strongly argue that now there are enough data to consider setting an estimated average requirement for vitamin D and to recognize the crucial need for more research to determine the role of vitamin D in noncalciotropic functions and prevention of chronic diseases

    Cod liver oil, vitamin A toxicity, frequent respiratory infections, and the vitamin D deficiency epidemic. Cannell JJ, Vieth R, Willett W, Zasloff M, Hathcock JN, White JH, Tanumihardjo SA, Larson-Meyer DE, Bischoff-Ferrari HA, Lamberg-Allardt CJ, Lappe JM, Norman AW, Zittermann A, Whiting SJ, Grant WB, Hollis BW, Giovannucci E. Ann Otol Rhinol Laryngol. 2008 Nov;117(11):864-70. Review. PMID: 19102134 Until we have better information on doses of vitamin D that will reliably provide adequate blood levels of 25(OH)D without toxicity, treatment of vitamin D deficiency in otherwise healthy children should be individualized according to the numerous factors that affect 25(OH)D levels, such as body weight, percent body fat, skin melanin, latitude, season of the year, and sun exposure.2 The doses of sunshine or oral vitamin D3 used in healthy children should be designed to maintain 25(OH)D levels above 50 ng/mL. As a rule, in the absence of significant sun exposure, we believe that most healthy children need about 1,000 IU of vitamin D3 daily per 11 kg (25 lb) of body weight to obtain levels greater than 50 ng/mL. Some will need more, and others less. In our opinion, children with chronic illnesses such as autism, diabetes, and/or frequent infections should be supplemented with higher doses of sunshine or vitamin D3, doses adequate to maintain their 25(OH)D levels in the mid-normal of the reference range (65 ng/mL) - and should be so supplemented year round. Otolaryngologists treating children are in a good position to both diagnose and treat vitamin D deficiency.

Low vitamin D raises blood pressure in women: study | Health | Reuters - 0 views

  •  
    WASHINGTON (Reuters) - Younger white women with vitamin D deficiencies are about three times more likely to have high blood pressure in middle age than those with normal vitamin levels, according to a study released on Thursday. The study, presented at a meeting of the American Heart Association in Chicago, adds younger women to a growing list of people including men who may develop high blood pressure at least in part because of low vitamin D.

    Hypovitaminosis D in British adults at age 45 y: nationwide cohort study of dietary and lifestyle predictors. Hyppönen E, Power C. Am J Clin Nutr. 2007 Mar;85(3):860-8. PMID: 17344510 Conclusion: Prevalence of hypovitaminosis D in the general population was alarmingly high during the winter and spring, which warrants action at a population level rather than at a risk group level. Data from the 1958 birth cohort suggest that, at different cutoffs for hypovitaminosis D, a substantial public health problem exists in British whites. Obese participants and those living in Scotland were at the highest risk of hypovitaminosis D. However, the prevalence in the general population was very high during the winter and spring, which suggests that, to improve the situation, action is required at a population level rather than at a risk-group level. In the United States, calls have gone out for an increase in vitamin D fortification of foods (11), and the data from the current study suggest that such action is also warranted in the United Kingdom. Vitamin D is currently available without prescription as a dietary supplement only as part of cod liver oil or multivitamin products; hence, a need clearly exists to consider increased availability of over-the-counter supplements. Hypovitaminosis D has been implicated in the development of serious conditions, including diabetes, various types of cancer, and cardiovascular diseases, in addition to its essential role in maintaining bone health (1, 2). The high rates of hypovitaminosis D reported in this study suggest that immediate action is needed to improve the vitamin D status of the British population.

    In the July 2005 FASEB Journal, Adrian F. Gombart of the University of California, Los Angeles (UCLA) and his colleagues reported that vitamin D boosts production in white blood cells of one of the antimicrobial compounds that defends the body against germs.\n\nImmediately, Cannell says, the proverbial lightbulb went on in his head: Maybe the high doses of vitamin D that he had been prescribing to virtually all the men on his ward had boosted their natural arsenal of the antimicrobial, called cathelicidin, and protected them from flu. Cannell had been administering the vitamin D because his patients, like many other people in the industrial world, had shown a deficiency:

    The bioavailability of vitamin D from fortified cheeses and supplements is equivalent in adults. Wagner D, Sidhom G, Whiting SJ, Rousseau D, Vieth R. J Nutr. 2008 Jul;138(7):1365-71. PMID: 18567762 Compared with baseline, serum parathyroid hormone decreased with both fortification (P = 0.003) and supplementation (P = 0.012). These data demonstrate that vitamin D is equally bioavailable from fortified hard cheeses and supplements, making cheese suitable for vitamin D fortification.

    (VIDEO) Shedding light on the vitamin D deficiency 'crisis' By GrassRootsHealth.com Oct 11, 2009 - 4:49:39 PM San Diego, CA - Can vitamin D prevent 80% of the incidence of breast cancer? What is its affect on colon cancer and other major illnesses? These questions and more will be addressed when some of the most prominent vitamin D researchers in North America participate in the " Diagnosis & Treatment of Vitamin D Deficiency" seminar presented by GrassrootsHealth at the University of Toronto on Tuesday, November 3 from 8 a.m. - 5 p.m. GrassrootsHealth is the founder of D*action, an international public health project whose goal is to solve the vitamin D deficiency epidemic. GrassrootsHealth and D*action work with over 30 scientists, institutions and individuals committed to educate, test, and study vitamin D levels worldwide. At the conference, a group of physicians and researchers in the vitamin D field will discuss vitamin D's role in the potential prevention of many diseases, including breast cancer, colon cancer, type 1 diabetes and multiple sclerosis, the ultimate reduction in the incidence of infectious diseases and the economic impact of such action

    Serum 25-hydroxyvitamin D status of the US population: 1988-1994 compared with 2000-2004. Looker AC, Pfeiffer CM, Lacher DA, Schleicher RL, Picciano MF, Yetley EA. Am J Clin Nutr. 2008 Dec;88(6):1519-27. PMID: 19064511 doi:10.3945/ajcn.2008.26182 Conclusions: Overall, mean serum 25(OH)D was lower in 2000-2004 than 1988-1994. Assay changes unrelated to changes in vitamin D status accounted for much of the difference in most population groups. In an adult subgroup, combined changes in BMI, milk intake, and sun protection appeared to contribute to a real decline in vitamin D status. In summary, age-standardized mean serum 25(OH)D concentrations based on observed values were significantly lower in 2000-2004 than in 1988-1994 in all groups examined. Adjustment for assay changes noticeably reduced the difference between surveys. However, mean serum 25(OH)D concentrations remained significantly lower in males (except Mexican Americans) in NHANES 2000-2004 than in NHANES III, even after adjustment for assay differences. This remaining difference likely represents a real decline in vitamin D status. Changes in BMI, milk intake, and sun protection appeared to contribute to this decline in a subgroup of non-Hispanic white adults. The possibility that trends in overweight, sun protection, and milk intake may continue supports the need to continue monitoring the serum 25(OH)D status of the population
