The June 9, 2008 issue of Archives of Internal Medicine published by the American Medical Association presented the finding of Harvard researchers that men who have deficient vitamin D levels have a greater risk of myocardial infarction (heart attack) than men whose blood levels of the vitamin are sufficient. Edward Giovannucci,Isabel Marant Sneakers, MD of Harvard School of Public Health and his associates reviewed data from men aged 40 to 75 who participated in the Health Professionals Follow-up Study,Roger vivier uk, a prospective cohort investigation designed to evaluate associations between the occurrence of chronic disease and diet among male health care professionals who now have been followed for many years. Blood samples collected from 1993 to 1995 were analyzed for plasma 25-hydroxyvitamin D (25-OHD), lipoprotein and triglyceride levels, and diet and lifestyle factors were determined though the use of questionnaires which were given to each of the participants on study entry. Nine hundred participants without heart disease were matched for age, smoking status,Roger vivier outlet, and time of blood collection with 454 men of similar age (age 40 to 75) who had fatal coronary heart disease or non-fatal heart attack which was diagnosed in the 9 to 11 year period between the time of blood sample collection through January, 2004. Adjusted analysis of the data found a 2.42 times greater risk of heart attack among subjects with plasma vitamin D levels of 15 nanograms per milliliter or less compared with those whose levels were sufficient at 30 nanograms per milliliter or higher. Even those men whose vitamin D levels fell in an "intermediate range" had a 43 to 60 percent greater risk of heart attack compared to men with sufficient levels. Adjustment for a number of factors, such as family history of heart attack, failed to significantly reduce the association. Vitamin D as an anti-inflammatory agent showing benefit in cardiovascular disease is a possible mechanism of benefit,Giuseppe Zanotti Online, as cardiovascular disease has been linked in the past to inflammation and inflammatory markers such as C reactive protein, a protein often present when inflammation is present in the body. "If this association is causal, which remains to be established,Roger vivier flats, the amount of vitamin D required for optimal benefit may be much higher than would be provided by current recommendations (200-600 IU per day), especially in those with minimal sun exposure. Thus,giuseppe zanotti sandals, the present findings add further support that the current dietary requirements of vitamin D need to be increased to have an effect on circulating 25(OH)D levels substantially large enough for potential health benefits."

Giovannucci, et al.] Vitamin D and All-cause Mortality: This vitamin could help you live longer Low vitamin D levels have been linked with cancer, diabetes, and high blood pressure. Using the National Health and Nutrition Examination Survey,Nike Soccer Shoes Online, a large population-based study, researchers at the Albert Einstein College of Medicine evaluated whether low serum vitamin D levels were associated with mortality in the general population. These researchers studied the association of low vitamin D levels with all-cause mortality, cancer, and cardiovascular disease (CVD) mortality among 13,331 American adults who were 20 years or older. Vitamin D levels of these study participants were collected over a 6-year period (from 1988 through 1994), and participants were followed for mortality through the year 2000 (12 years). The researchers found that being older, female, nonwhite, having diabetes,cheap isabel marant, a current smoker,roger vivier mens, and having a higher body mass index were all independently associated with a greater risk of being vitamin D deficient, while greater physical activity, vitamin D supplementation, and evaluating subjects in a non-winter season (greater exposure to sunshine) were all associated with higher levels of vitamin D. Being in the lowest quartile (defined as vitamin D levels less than 17.8 ng/mL) was associated with a 26% increased rate of death from any cause (mortality rate ratio,Roger vivier flats, 1.26; 95% CI,Roger Vivier Flats Online, 1.08-1.46). The adjusted models of CVD and cancer mortality revealed a higher risk, but it was not statistically significant. Richards and coworkers examined whether vitamin D concentrations could slow the rate of shortening of telomeres on leukocytes (a marker of aging). Leukocyte telomere length (LTL) is predictive of the development of numerous aging-related disease, and length of leukocyte telomeres decreases with each cell division and with increased inflammation (more common in the elderly). Researchers measured the concentrations of vitamin D in the blood of 2160 women aged 18-79 years (the mean age of these women was about 49 years) from a large population-based study. This study divided the group into thirds [tertiles] based on vitamin D levels,Roger vivier, and found that increased age was significantly associated with shorter LTL (r = -0.40,Cheap Isabel Marant Sneakers, P This information was originally posted at: Beneficial Effects of Vitamin D Dr. Steven Petrosino received his Baccalaureate (BA) degree in both Science and English from Penn State University in 1975, pursued his Masters degree (American Studies) with honors at Penn State in 1977-1978, and graduated Summa Cum Laude with a Doctorate in Nutrition from Lasalle University in 1995. program at Walden University (Public Health).
