    A prospective study of egg consumption and risk of cardiovascular disease in men and women. Hu FB, Stampfer MJ, Rimm EB, Manson JE, Ascherio A, Colditz GA, Rosner BA, Spiegelman D, Speizer FE, Sacks FM, Hennekens CH, Willett WC. JAMA. 1999 Apr 21;281(15):1387-94. PMID: 10217054 Results We documented 866 incident cases of CHD and 258 incident cases of stroke in men during 8 years of follow-up and 939 incident cases of CHD and 563 incident cases of stroke in women during 14 years of follow-up. After adjustment for age, smoking, and other potential CHD risk factors, we found no evidence of an overall significant association between egg consumption and risk of CHD or stroke in either men or women. The relative risks (RRs) of CHD across categories of intake were less than 1 per week (1.0), 1 per week (1.06), 2 to 4 per week (1.12), 5 to 6 per week (0.90), and >=1 per day (1.08) (P for trend=.75) for men; and less than 1 per week (1.0), 1 per week (0.82), 2 to 4 per week (0.99), 5 to 6 per week (0.95), and >=1 per day (0.82) (P for trend=.95) for women. In subgroup analyses, higher egg consumption appeared to be associated with increased risk of CHD only among diabetic subjects (RR of CHD comparing more than 1 egg per day with less than 1 egg per week among diabetic men, 2.02 [95% confidence interval, 1.05-3.87; P for trend=.04], and among diabetic women, 1.49 [0.88-2.52; P for trend=.008]). Conclusions These findings suggest that consumption of up to 1 egg per day is unlikely to have substantial overall impact on the risk of CHD or stroke among healthy men and women. The apparent increased risk of CHD associated with higher egg consumption among diabetic participants warrants further research.

    Prospective study of predictors of vitamin D status and cancer incidence and mortality in men. Giovannucci E, Liu Y, Rimm EB, Hollis BW, Fuchs CS, Stampfer MJ, Willett WC. J Natl Cancer Inst. 2006 Apr 5;98(7):451-9. PMID: 16595781 doi:10.1093/jnci/djj101 Conclusions: Low levels of vitamin D may be associated with increased cancer incidence and mortality in men, particularly for digestive-system cancers. The vitamin D supplementation necessary to achieve a 25(OH)D increment of 25 nmol/L may be at least 1500 IU/day.

    Coffee, decaffeinated coffee, and tea consumption in relation to incident type 2 diabetes mellitus: A systematic review with meta-analysis. Huxley R, Lee CM, Barzi F, Timmermeister L, Czernichow S, Perkovic V, Grobbee DE, Batty D, Woodward M. Arch Intern Med. 2009 Dec 14;169(22):2053-63. PMID: 20008687 Conclusions Owing to the presence of small-study bias, our results may represent an overestimate of the true magnitude of the association. Similar significant and inverse associations were observed with decaffeinated coffee and tea and risk of incident diabetes. High intakes of coffee, decaffeinated coffee, and tea are associated with reduced risk of diabetes. The putative protective effects of these beverages warrant further investigation in randomized trials.

GrassrootsHealth | Vitamin D Action - Vitamin D Scientists' Call to Action Statement - 0 views

  •  
    "We are aware of substantial scientific evidence supporting the role of vitamin D in prevention of cancer. It has been reasonably established that adequate serum vitamin D metabolite levels are associated with substantially lower incidence rates of several types of cancer, including those of the breast, colon, and ovary, and other sites. We have concluded that the vitamin D status of most individuals in North America will need to be greatly improved for substantial reduction in incidence of cancer. Epidemiological studies have shown that higher vitamin D levels are also associated with lower risk of Type I diabetes in children and of multiple sclerosis. Several studies have found that markers of higher vitamin D levels are associated with lower incidence and severity of influenza and several other infectious diseases."

    Higher levels of 25-hydroxyvitamin D are associated with a lower incidence of multiple sclerosis only in women. Kragt J, van Amerongen B, Killestein J, Dijkstra C, Uitdehaag B, Polman Ch, Lips P. Mult Scler. 2009 Jan;15(1):9-15. Epub 2008 Aug 13. PMID: 18701572 DOI: 10.1177/1352458508095920 CONCLUSIONS: Our data suggest that higher circulating levels of 25(OH)D are associated with a lower incidence of MS and MS-related disability in women. This may imply clues to the pathogenesis of the sex difference in risk and to the nature of the environmental factors involved in MS.

    Plasma 25-hydroxyvitamin D levels and risk of incident hypertension among young women. Forman JP, Curhan GC, Taylor EN. Hypertension. 2008 Nov;52(5):828-32. Epub 2008 Oct 6. PMID: 18838623 doi: 10.1161/HYPERTENSIONAHA.108.117630 Women in the lowest compared with highest quartile of plasma 25(OH)D had an adjusted odds ratio for incident hypertension of 1.66 (95% CI: 1.11 to 2.48; P for trend=0.01). Compared with women with sufficient levels, those with vitamin D deficiency (<30 ng/mL; 65.7% of the study population) had a multivariable odds ratio of 1.47 (95% CI: 1.10 to 1.97). Plasma 25(OH)D levels are inversely and independently associated with the risk of developing hypertension.

Is vitamin D deficiency linked to Alzheimer's disease and vascular dementia? - 0 views

  •  
    Amsterdam, The Netherlands, May 26, 2009 - There are several risk factors for the development of Alzheimer's disease and vascular dementia. Based on an increasing number of studies linking these risk factors with Vitamin D deficiency, an article in the current issue of the Journal of Alzheimer's Disease (May 2009) by William B. Grant, PhD of the Sunlight, Nutrition, and Health Research Center (SUNARC) suggests that further investigation of possible direct or indirect linkages between Vitamin D and these dementias is needed. Low serum levels of 25-hydroxyvitamin D [25(OH)D] have been associated with increased risk for cardiovascular diseases, diabetes mellitus, depression, dental caries, osteoporosis, and periodontal disease, all of which are either considered risk factors for dementia or have preceded incidence of dementia. In 2008, a number of studies reported that those with higher serum 25(OH)D levels had greatly reduced risk of incidence or death from cardiovascular diseases

    Incidence of reported cold/influenza symptoms according to season. The 104 subjects in the placebo group (light shade) reported cold and flu symptoms year around with the most symptoms in the winter. While on 800 IU per day (intermediate shade) the 104 test subjects were as likely to get sick in the summer as the winter. Only one of the 104 test subjects had cold/influenza symptoms during the final year of the trial, when they took 2,000 IU of vitamin D per day (dark shading).

    Plasma 25-hydroxyvitamin D and 1,25-dihydroxyvitamin D and risk of incident ovarian cancer. Tworoger SS, Lee IM, Buring JE, Rosner B, Hollis BW, Hankinson SE. Cancer Epidemiol Biomarkers Prev. 2007 Apr;16(4):783-8. PMID: 17416771 doi: 10.1158/1055-9965.EPI-06-0981 Overall, our results do not suggest that plasma vitamin D levels are associated with risk of ovarian cancer. However, we observed significant associations in some subgroups, which should be evaluated further in other studies because increasing vitamin D intake is an easy preventive measure to adopt.

    Fatigue fractures in military conscripts : A study on risk factors, diagnostics and long-term consequences Ruohola, Juha-Petri University of Helsinki, Faculty of Medicine, Institute of Clinical Medicine, Orthopaedics and Traumatology, Helsinki University Central Hospital Centre of Military Medicine, Helsinki 2007-03-09 Doctoral dissertation (article-based) It seems likely that low vitamin D levels are related to fatigue fractures, and that an increasing trend exists between TRACP-5b bone resorption marker elevation and fatigue fracture incidence. Though seldom detected by plain radiography, fatigue fractures often underlie unclear lower leg stress-related pain occurring in the distal parts of the tibia. Femoral neck fatigue fractures, when displaced, lead to long-term morbidity in a high percentage of patients, whereas, when non-displaced, they do not predispose patients to subsequent adverse complications. Importantly, an educational intervention can diminish the incidence of fracture displacement by enhancing awareness and providing instructions for earlier diagnosis of fatigue fractures

    Calcium and vitamin d supplementation decreases incidence of stress fractures in female navy recruits. Lappe J, Cullen D, Haynatzki G, Recker R, Ahlf R, Thompson K. J Bone Miner Res. 2008 May;23(5):741-9. PMID: 18433305 doi: 10.1359/jbmr.080102 Conclusions: Generalizing the findings to the population of 14,416 women who entered basic training at the Great Lakes during the 24 mo of recruitment, calcium and vitamin D supplementation for the entire cohort would have prevented 187 persons from fracturing. Such a decrease in SFx would be associated with a significant decrease in morbidity and financial costs.

    (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
