Women With Breast Cancer Have Low Vitamin D Levels - 0 views

  •  
    "ScienceDaily (Oct. 8, 2009) - Women with breast cancer should be given high doses of vitamin D because a majority of them are likely to have low levels of vitamin D, which could contribute to decreased bone mass and greater risk of fractures, according to scientists at the University of Rochester Medical Center."

    Scientists funded by the NCI analyzed vitamin D levels in each woman, and the average level was 27 nanograms per milliliter; more than two-thirds of the women had vitamin deficiency. Weekly supplementation with high doses of vitamin D -- 50,000 international units or more -- improved the levels, according to Peppone's study.

    The U.S. Institute of Medicine suggests that blood levels nearing 32 nanograms per milliliter are adequate.

Relationship Between Vitamin D Deficiency And Increased Inflammation In Healthy Women - 0 views

  •  
    According to a recent study in the Archives of Internal Medicine, 75 percent of Americans do not get enough Vitamin D. Researchers have found that the deficiency may negatively impact immune function and cardiovascular health and increase cancer risk. Now, a University of Missouri nutritional sciences researcher has found that vitamin D deficiency is associated with inflammation, a negative response of the immune system, in healthy women.

    Serum tumor necrosis factor-alpha concentrations are negatively correlated with serum 25(OH)D concentrations in healthy women.
    Peterson CA, Heffernan ME.
    J Inflamm (Lond). 2008 Jul 24;5:10.
    PMID: 18652680
    doi:10.1186/1476-9255-5-10

    Conclusion
    Serum 25(OH)D status is inversely related to TNF-α concentrations in healthy women, which may in part explain this vitamin's role in the prevention and treatment of inflammatory diseases. Results gleaned from this investigation also support the need to re-examine the biological basis for determining optimal vitamin D status.

Low Levels Of Vitamin D In Patients With Autoimmune Disease May Be Result, Not Cause, O... - 0 views

  •  
    ScienceDaily (Apr. 8, 2009) - Deficiency in vitamin D has been widely regarded as contributing to autoimmune disease, but a review appearing in Autoimmunity Reviews explains that low levels of vitamin D in patients with autoimmune disease may be a result rather than a cause of disease and that supplementing with vitamin D may actually exacerbate autoimmune disease.

The Heart Scan Blog: Vitamin D for Peter, Paul, and Mary - 0 views

  •  
    Why is it that vitamin D deficiency can manifest in so many different ways in different people? One big reason is something called vitamin D receptor (VDR) genotypes, the variation in the receptor for vitamin D.

    Why is it that the dose of vitamin D necessary to reach a specific level differs so widely from one person to the next? VDR genotype, again. Variation in blood levels of 25-hydroxy vitamin D from a specific dose of vitamin D can vary three-fold, as shown by a University of Toronto study. In other words, a dose of 4000 units per day may yield a 25-hydroxy vitamin D blood level of 30 ng/ml in Mary, 60 ng/ml in Paul, and 90 ng/ml in Pete--same dose, different blood levels.

Mean Serum 25(OH)D Levels Decreasing in All Categories of the US Population - 0 views

  •  
    March 27, 2009 - A significant decrease in serum 25-hydroxyvitamin D (25[OH]D) levels has led to an increase in vitamin D insufficiency in the US population, especially in racial and ethnic groups, according to results of a population-based study reported in the March 23 issue of the Archives of Internal Medicine.

    "Vitamin D insufficiency has been associated with increases in cardiovascular disease, cancer, and infection," write Adit A. Ginde, MD, from the Department of Emergency Medicine at the University of Colorado Denver School of Medicine, Aurora, Colorado, and colleagues. "Vitamin D supplementation appears to mitigate the incidence and adverse outcomes of these diseases and may reduce all-cause mortality."

    [...]

    "These findings have important implications for health disparities and public health," the study authors conclude. "Our data provide additional evidence that current recommendations for vitamin D supplementation (200-600 IU/d) are inadequate to achieve optimal serum 25(OH)D levels in most of the US population." They add that large, randomized controlled trials of higher doses of vitamin D supplementation are needed to evaluate their effect on general health and mortality.

Shedding Light on Vitamin D and Cancer - 0 views

  •  
    Vitamin D's days of obscurity seem pretty much over. Once just an afterthought to most people-relegated to the sides of milk cartons and the pages of medical texts-it's now on the cusp of becoming a full-fledged disease prevention star. Although vitamin D has long been known as an important factor in bone health, a quickly growing body of evidence now shows that it may also help lower the risk of cancer, heart disease, and even premature death.[1], [2] Not surprisingly, scientists and the public have started to take note, particularly of vitamin D's potential to protect against cancer
