25-Hydroxyvitamin D Levels Inversely Associate with Risk for Developing Coronary Artery Calcification -- de Boer et al. 20 (8): 1805 -- Journal of the American Society of Nephrology - 0 views

  •  
    25-hydroxyvitamin D levels inversely associate with risk for developing coronary artery calcification. de Boer IH, Kestenbaum B, Shoben AB, Michos ED, Sarnak MJ, Siscovick DS. J Am Soc Nephrol. 2009 Aug;20(8):1805-12. Epub 2009 May 14. PMID: 19443637 doi: 10.1681/ASN.2008111157 "In conclusion, lower 25-hydroxyvitamin D concentrations associate with increased risk for incident CAC. Accelerated development of atherosclerosis may underlie, in part, the increased cardiovascular risk associated with vitamin D deficiency."

Association Between Serum 25-Hydroxyvitamin D Level and Upper Respiratory Tract Infection in the Third National Health and Nutrition Examination Survey, February 23, 2009, Ginde et al. 169 (4): 384 - Arch Intern Med -- Abstract - 0 views

  •  
    Association between serum 25-hydroxyvitamin D level and upper respiratory tract infection in the Third National Health and Nutrition Examination Survey. Ginde AA, Mansbach JM, Camargo CA Jr. Arch Intern Med. 2009 Feb 23;169(4):384-90. PMID: 19237723 Conclusions Serum 25(OH)D levels are inversely associated with recent URTI. This Association may be stronger in those with respiratory tract diseases. Randomized controlled trials are warranted to explore the effects of vitamin D supplementation on RTI.

The Association of Solar Ultraviolet B (UVB) with Reducing Risk of Cancer: Multifactorial Ecologic Analysis of Geographic Variation in Age-adjusted Cancer Mortality Rates - Anticancer Research - 0 views

  •  
    The association of solar ultraviolet B (UVB) with reducing risk of cancer: multifactorial ecologic analysis of geographic variation in age-adjusted cancer mortality rates. Grant WB, Garland CF. Anticancer Res. 2006 Jul-Aug;26(4A):2687-99. PMID: 16886679 CONCLUSION: These results provide additional support for the hypothesis that solar UVB, through photosynthesis of vitamin D, is inversely-associated with cancer mortality rates, and that various other cancer risk-modifying factors do not detract from this link. It is thought that sun avoidance practices after 1980, along with improved cancer treatment, led to reduced associations in the latter period. The results regarding solar UVB should be studied further with additional observational and intervention studies of vitamin D indices and cancer incidence, mortality and survival rates.

Vitamin D and vitamin D analogues for preventing fractures associated with involutional and post-menopausal osteoporosis - 0 views

  •  
    Vitamin D and vitamin D analogues for preventing fractures associated with involutional and post-menopausal osteoporosis. Avenell A, Gillespie WJ, Gillespie LD, O'Connell D. Cochrane Database Syst Rev. 2009 Apr 15;(2):CD000227. Review. PMID: 19370554 DOI: 10.1002/14651858.CD000227.pub3 AUTHORS' CONCLUSIONS: Frail older people confined to institutions may sustain fewer hip fractures if given vitamin D with calcium. Vitamin D alone is unlikely to prevent fracture. Overall there is a small but significant increase in gastrointestinal symptoms and renal disease associated with vitamin D or its analogues. Calcitriol is associated with an increased incidence of hypercalcaemia.

Calcium and vitamin D intakes may be positively associated with brain lesions in depressed and non-depressed elders - 0 views

  •  
    Calcium and vitamin D intakes may be positively associated with brain lesions in depressed and nondepressed elders. Payne ME, Anderson JJ, Steffens DC. Nutr Res. 2008 May;28(5):285-92. PMID: 19083421 doi: 10.1016/j.nutres.2008.02.013 In conclusion, calcium and vitamin D consumption were associated with brain lesions in elderly subjects even after controlling for potentially explanatory variables. These associations may be due to vascular calcification or other mechanism. The possibility of adverse effects of high intakes of calcium and vitamin D needs to be further explored in longitudinal studies of elderly subjects.

Higher Levels of Vitamin D May Be Associated with a Lower Risk of Lung Cancer in Women and Younger Subjects by Derrick DeSilva Jr., M.D. - Alternative Health Blog - Alternative Health Journal - 0 views

  •  
    "In a prospective study involving 6,937 men and women, higher levels of vitamin D were associated with a significantly lower risk of lung cancer in women and younger participants. During a maximum follow-up of 24 years, 122 cases of lung cancer were identified. After adjusting for potential confounders, higher serum 25-hydroxyvitamin D levels were associated with reduced risk of lung cancer risk in women (84% reduced risk) and younger participants (66% reduced risk). No association was observed between vitamin D status and lung cancer risk in men and older participants. "

    Typically, grains, such as whole wheat tiniest seed, really are a delicious supply of insoluble dietary fiber. In the event that you're actually sensation supported, it's the actual insoluble dietary fiber that'll become the broom as well as drive away everything waste materials. Getting lots of insoluble dietary fiber in what you eat retains a person normal, even though it's essential to pay attention to your general dietary fiber suggestion, not only obtaining a particular kind of dietary fiber. For any typical two, 000-calorie diet plan, you'll require twenty-eight gr associated with dietary fiber, that fulfills the actual fourteen gr for each each and every 1, 000-caloirie increment suggestion, based on the Nutritional Recommendations with regard to People in america, 2010. Discovering a method to eat simply one-quarter mug associated with whole wheat tiniest seed every single day, which supplies 3. 8 gr associated with complete dietary fiber, occupies almost fourteen % of the suggestion.

    Effectiveness and safety of vitamin D in relation to bone health. Cranney A, Horsley T, O'Donnell S, Weiler H, Puil L, Ooi D, Atkinson S, Ward L, Moher D, Hanley D, Fang M, Yazdi F, Garritty C, Sampson M, Barrowman N, Tsertsvadze A, Mamaladze V. Evid Rep Technol Assess (Full Rep). 2007 Aug;(158):1-235. Review. PMID: 18088161 CONCLUSIONS: The results highlight the need for additional high quality studies in infants, children, premenopausal women, and diverse racial or ethnic groups. There was fair evidence from studies of an association between circulating 25(OH)D concentrations with some bone health outcomes (established rickets, PTH, falls, BMD). However, the evidence for an association was inconsistent for other outcomes (e.g., BMC in infants and fractures in adults). It was difficult to define specific thresholds of circulating 25(OH)D for optimal bone health due to the imprecision of different 25(OH)D assays. Standard reference preparations are needed so that serum 25(OH)D can be accurately and reliably measured, and validated. In most trials, the effects of vitamin D and calcium could not be separated. Vitamin D(3) (>700 IU/day) with calcium supplementation compared to placebo has a small beneficial effect on BMD, and reduces the risk of fractures and falls although benefit may be confined to specific subgroups. Vitamin D intake above current dietary reference intakes was not reported to be associated with an increased risk of adverse events. However, most trials of higher doses of vitamin D were not adequately designed to assess long-term harms.

DHA reduces tumor growth - Life Extension Update - 0 views

  •  
    Mice injected with cancer cells experienced significantly elevated levels of C-reactive protein, white blood cells, and lipid peroxidation compared with control mice. These levels were reduced in animals that received cisplatin and/or DHA. While treatment with 125 mg/kg DHA inhibited tumor growth by 38 percent compared to untreated animals, 250 mg/kg suppressed tumor growth by 79 percent, which was a greater effect than that of cisplatin alone (which was associated with a 55 percent reduction). The combination of DHA and cisplatin resulted in an 81 percent inhibition of growth, while reducing elevated white blood cell levels (leukocytosis) to normal levels. Treatment with the higher dose of DHA alone was associated with a similar reduction in white blood cells, which, when elevated, are associated with tumor growth. A strong relationship was observed between tumor growth and white blood cell levels as well as C-reactive protein levels. In another experiment with rats treated with cisplatin, the addition of 250 mg/kg DHA prevented lethal kidney toxicity in 88 percent of the animals that received it, while none of the rats that received cisplatin alone survived.

    Meat intake and mortality: a prospective study of over half a million people. Sinha R, Cross AJ, Graubard BI, Leitzmann MF, Schatzkin A. Arch Intern Med. 2009 Mar 23;169(6):562-71. PMID: 19307518 Red and processed meat intakes were associated with modest increases in total mortality, cancer mortality, and cardiovascular disease mortality. When comparing the highest with the lowest quintile of white meat intake, there was an inverse association for total mortality and cancer mortality, as well as all other deaths for both men (Table 2) and women (Table 3). In contrast, there was a small increase in risk for CVD mortality in men with higher intake of white meat. There was no association between white meat consumption and death from injuries and sudden death in men or women.

    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.

Quantitative Analysis of the Benefits and Risks of Consuming Farmed and Wild Salmon -- Foran et al. 135 (11): 2639 -- Journal of Nutrition - 0 views

  •  
    Quantitative analysis of the benefits and risks of consuming farmed and wild salmon. Foran JA, Good DH, Carpenter DO, Hamilton MC, Knuth BA, Schwager SJ. J Nutr. 2005 Nov;135(11):2639-43. PMID: 16251623 Contaminants in farmed Atlantic and wild Pacific salmon raise important questions about the competing health benefits and risks of fish consumption. A benefit-risk analysis was conducted to compare quantitatively the cancer and noncancer risks of exposure to organic contaminants in salmon with the (n-3) fatty acid-associated health benefits of salmon consumption. Recommended levels of (n-3) fatty acid intake, as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), may be achieved by consuming farmed or wild salmon while maintaining an acceptable level of noncarcinogenic risk. However, the recommended level of EPA+DHA intake cannot be achieved solely from farmed or wild salmon while maintaining an acceptable level of carcinogenic risk. Although the benefit-risk ratio for carcinogens and noncarcinogens is significantly greater for wild Pacific salmon than for farmed Atlantic salmon as a group, the ratio for some subgroups of farmed salmon is on par with the ratio for wild salmon. This analysis suggests that risk of exposure to contaminants in farmed and wild salmon is partially offset by the fatty acid-associated health benefits. However, young children, women of child-bearing age, pregnant women, and nursing mothers not at significant risk for sudden cardiac death associated with CHD but concerned with health impairments such as reduction in IQ and other cognitive and behavioral effects, can minimize contaminant exposure by choosing the least contaminated wild salmon or by selecting other sources of (n-3) fatty acids.

    Vitamin D, aging, and cancer. Tuohimaa P. Nutr Rev. 2008 Oct;66(10 Suppl 2):S147-52. Review. PMID: 18844842 DOI: 10.1111/j.1753-4887.2008.00095.x Deficiency of the prohormone calcidiol (25OH vitamin D3) seems to be associated with several aging-related chronic diseases including cancer. Our results suggest that calcidiol is mainly responsible for differentiation homeostasis, whereas calcitriol might be more involved in calcium homeostasis. Therefore, an imbalance of calcidiol rather than calcitriol is a risk factor for cancer and chronic diseases. Calcidiol insufficiency, as well as insufficient solar exposure, is associated with increased risk of several solid cancers. Both a vitamin D3 deficiency and a high concentration of calcidiol may increase cancer risk. Similarly, aging phenomena show a U-shaped association with vitamin D bioactivity. Therefore, the chronic diseases and cancers related to aging might be prevented by an optimal concentration of serum calcidiol, which remains to be determined.

    Vitamin D, nervous system and aging. P. Tuohimaa, T. Keisala, A. Minasyan, J. Cachat and A. Kalueff. . Psychoneuroendocrinology, Volume 34, Supplement 1, December 2009, Pages S278-S286 NEUROACTIVE STEROIDS: EFFECTS AND MECHANISMS OF ACTION doi:10.1016/j.psyneuen.2009.07.003 This is a mini-review of vitamin D3, its active metabolites and their functioning in the central nervous system (CNS), especially in relation to nervous system pathologies and aging. The vitamin D3 endocrine system consists of 3 active calcipherol hormones: calcidiol (25OHD3), 1α-calcitriol (1α,25(OH)2D3) and 24-calcitriol (24,25(OH)2D3). The impact of the calcipherol hormone system on aging, health and disease is discussed. Low serum calcidiol concentrations are associated with an increased risk of several chronic diseases including osteoporosis, cancer, diabetes, autoimmune disorders, hypertension, atherosclerosis and muscle weakness all of which can be considered aging-related diseases. The relationship of many of these diseases and aging-related changes in physiology show a U-shaped response curve to serum calcidiol concentrations. Clinical data suggest that vitamin D3 insufficiency is associated with an increased risk of several CNS diseases, including multiple sclerosis, Alzheimer's and Parkinson's disease, seasonal affective disorder and schizophrenia. In line with this, recent animal and human studies suggest that vitamin D insufficiency is associated with abnormal development and functioning of the CNS. Overall, imbalances in the calcipherol system appear to cause abnormal function, including premature aging, of the CNS.

    Food Choices and Coronary Heart Disease: A Population Based Cohort Study of Rural Swedish Men with 12 Years of Follow-up. Sara Holmberg, Anders Thelin and Eva-Lena Stiernström. Int. J. Environ. Res. Public Health 2009, 6(10), 2626-2638; doi:10.3390/ijerph6102626 - published online 12 October 2009 Coronary heart disease is associated with diet. Nutritional recommendations are frequently provided, but few long term studies on the effect of food choices on heart disease are available. We followed coronary heart disease morbidity and mortality in a cohort of rural men (N = 1,752) participating in a prospective observational study. Dietary choices were assessed at baseline with a 15-item food questionnaire. 138 men were hospitalized or deceased owing to coronary heart disease during the 12 year follow-up. Daily intake of fruit and vegetables was associated with a lower risk of coronary heart disease when combined with a high dairy fat consumption (odds ratio 0.39, 95% CI 0.21-0.73), but not when combined with a low dairy fat consumption (odds ratio 1.70, 95% CI 0.97-2.98). Choosing wholemeal bread or eating fish at least twice a week showed no association with the outcome.
