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."

    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

    There was a protective effect of UVB irradiance on risk of breast cancer that was independent of fertility rate, proportion of the population overweight, alcohol intake, animal energy intake, and other covariates.

    Vitamin D for cancer prevention: global perspective.
    Garland CF, Gorham ED, Mohr SB, Garland FC.
    Ann Epidemiol. 2009 Jul;19(7):468-83. Review.
    PMID: 19523595

    RESULTS/CONCLUSIONS: It is projected that raising the minimum year-around serum 25(OH)D level to 40 to 60 ng/mL (100-150 nmol/L) would prevent approximately 58,000 new cases of breast cancer and 49,000 new cases of colorectal cancer each year, and three fourths of deaths from these diseases in the United States and Canada, based on observational studies combined with a randomized trial. Such intakes also are expected to reduce case-fatality rates of patients who have breast, colorectal, or prostate cancer by half. There are no unreasonable risks from intake of 2000 IU per day of vitamin D(3), or from a population serum 25(OH)D level of 40 to 60 ng/mL. The time has arrived for nationally coordinated action to substantially increase intake of vitamin D and calcium.

    Vitamin D and prevention of breast cancer: pooled analysis.
    Garland CF, Gorham ED, Mohr SB, Grant WB, Giovannucci EL, Lipkin M, Newmark H, Holick MF, Garland FC.
    J Steroid Biochem Mol Biol. 2007 Mar;103(3-5):708-11.
    PMID: 17368188

    CONCLUSIONS: Intake of 2000 IU/day of Vitamin D(3), and, when possible, very moderate exposure to sunlight, could raise serum 25(OH)D to 52 ng/ml, a level associated with reduction by 50% in incidence of breast cancer, according to observational studies.

    "A study conducted by Cedric Garland and other prominent vitamin D researchers determined that women with vitamin D levels above 52 ng/ml have half the risk of developing breast cancer as those with 13 ng/ml! Garland (et al) estimates that 58,000 new cases of breast cancer in the U.S. could be prevented per year by raising vitamin D levels to 52 ng/ml. Imagine what the global impact could be! "

    Vitamin D status differs by latitude and race, with residents of the northeastern United States and individuals with more skin pigmentation being at increased risk of deficiency. A PubMed database search yielded 63 observational studies of vitamin D status in relation to cancer risk, including 30 of colon, 13 of breast, 26 of prostate, and 7 of ovarian cancer, and several that assessed the association of vitamin D receptor genotype with cancer risk.

    The majority of studies found a protective relationship between sufficient vitamin D status and lower risk of cancer. The evidence suggests that efforts to improve vitamin D status, for example by vitamin D supplementation, could reduce cancer incidence and mortality at low cost, with few or no adverse effects.

    Serum 25-hydroxyvitamin D and colon cancer: eight-year prospective study.
    Garland CF, Comstock GW, Garland FC, Helsing KJ, Shaw EK, Gorham ED.
    Lancet. 1989 Nov 18;2(8673):1176-8.
    PMID: 2572900

    Blood samples taken in 1974 in Washington County, Maryland, from 25 620 volunteers were used to investigate the relation of serum 25-hydroxyvitamin D (25-OHD) with subsequent risk of getting colon cancer. 34 cases of colon cancer diagnosed between August, 1975, and January, 1983, were matched to 67 controls by age, race, sex, and month blood was taken. Risk of colon cancer was reduced by 75% in the third quintile (27-32 ng/ml) and by 80% in the fourth quintile (33-41 ng/ml) of serum 25-OHD. Risk of getting colon cancer decreased three-fold in people with a serum 25-OHD concentration of 20 ng/ml or more. The results are consistent with a protective effect of serum 25-OHD on colon cancer.

    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.

  •  
    San Diego, CA (PRWEB) May 25, 2009 -- Coming on the heels of the publishing in the Annals of Epidemiology of a new study led by Dr. Cedric Garland, on the preventive measures of vitamin D, GrassrootsHealth D*action Project is calling on physicians, health clinics and groups throughout the country to recognize the need for determining vitamin D levels and to ensure the public have their blood levels of vitamin D tested.

    According to research from the newly published study by Cedric F. Garland, Dr. P.H., FACE, Department of Family and Preventive Medicine and Moores Cancer Center of the University of California, San Diego (UCSD), "It is projected that raising the minimum year-around serum 25(OH)D level to 40-60 ng/ml (100-150 nmol/L) would prevent approximately 58,000 new cases of breast cancer and 49,000 new cases of colorectal cancer each year, and three quarters of deaths from these diseases, in the US and Canada."

    Geographic variation in breast cancer mortality in the United States: a hypothesis involving exposure to solar radiation.
    Garland FC, Garland CF, Gorham ED, Young JF.
    Prev Med. 1990 Nov;19(6):614-22.
    PMID: 2263572
    doi:10.1016/0091-7435(90)90058-R

    Vitamin D from sunlight exposure may be associated with low risk for fatal breast cancer, and differences in ultraviolet light reaching the United States population may account for the striking regional differences in breast cancer mortality. The ecological nature of this study is emphasized, and the possibility that an indirect association with dietary and socioeconomic factors could explain these findings is discussed.

The health benefits of vitamin D greatly outweigh the health risks - 0 views

  •  
    In his recent essay, Trevor G. Marshall explores how vitamin D supplementation may be contributing to the current epidemics of obesity and chronic disease[1]. Unfortunately, he has overlooked many important papers that disagree with his hypothesis. This letter points out some of the omissions.
    The health benefits of vitamin D3 have been reviewed recently[2]. The benefits for bone health have been known for nearly a century. Benefits for cancer, infectious diseases, autoimmune diseases, and metabolic diseases have been identified in the past three decades.
