    Seasonality of UV-radiation and vitamin D status at 69 degrees north.
    Brustad M, Edvardsen K, Wilsgaard T, Engelsen O, Aksnes L, Lund E.
    Photochem Photobiol Sci. 2007 Aug;6(8):903-8. Epub 2007 Jun 27.
    PMID: 17668121

    The generally high dietary intakes of vitamin D, especially in winter, mask largely the effect of seasonal variation in UV-exposure, causing an atypical seasonal variation in vitamin D status. The UV-hour variable significantly predicted 25(OH)D levels in blood when adjusted for intakes and artificial UV-radiation exposure and sun holidays abroad.

    "In 1995 my son received the devastating diagnosis of MS. Having been a research scientist for 30 years, I decided to plunge into the scientific literature for MS to determine the most likely factors which cause MS and to use this information to develop an effective therapy for my son.

    Notably, many people are having great success in halting or greatly slowing MS with nutritional strategies; many Testimonials are available. I am most pleased to report that my son remains in excellent health with no MS symptoms.

    I discovered abundant scientific evidence that indicates that various nutritional factors potentially play major roles in the onset and progression of MS. Strangely, this information was not being made available to persons with MS by doctors nor by established MS charities."

    Food chain as origin of vitamin D in fish
    D. Sunita Rao and N. Raghuramulu.
    Comparative Biochemistry and Physiology Part A: Physiology
    Volume 114, Issue 1, May 1996, Pages 15-19
    doi:10.1016/0300-9629(95)02024-1

    Plankton, the chief food source of fish, was assessed as the possible dietary origin of vitamin D in fish. The presence of vitamin D compounds were examined in fresh water phytoplankton and zooplankton employing a series of chromatographic procedures. Abundant amounts of provitamins D and vitamins D (D2 and D3) were found in the fresh water plankton. The high amount of vitamin D observed may be due to exposure of plankton to sunlight because the plankton were caught during the summer month. Thus, plankton may be an important contributor to vitamin D in fish.

    Vitamin D intake is inversely associated with rheumatoid arthritis: results from the Iowa Women's Health Study.

    Arthritis Rheum. 2004 Jan;50(1):72-7.
    PMID: 14730601
    DOI: 10.1002/art.11434

    CONCLUSION: Greater intake of vitamin D may be associated with a lower risk of RA in older women, although this finding is hypothesis generating.

    Vitamin D from dietary intake and sunlight exposure and the risk of hormone-receptor-defined breast cancer.
    Blackmore KM, Lesosky M, Barnett H, Raboud JM, Vieth R, Knight JA.
    Am J Epidemiol. 2008 Oct 15;168(8):915-24. Epub 2008 Aug 27.
    PMID: 18756015
    doi:10.1093/aje/kwn198

    This study suggests that vitamin D is associated with a reduced risk of breast cancer regardless of ER/PR status of the tumor. Future studies with a larger number of receptor-negative and mixed tumors are required.

    Dietary vitamin D and cancers of the oral cavity and esophagus.

    Ann Oncol. 2009 Sep;20(9):1576-81. Epub 2009 Jun 1.
    PMID: 19487490

    Conclusion: We observed inverse associations between dietary vitamin D intake and risk of SCCE and, perhaps, oral/pharyngeal cancer, which were most pronounced among heavy current smokers and heavy consumers of alcohol.

    J Am Coll Nutr. 2006 Jun;25(3):224-30.
    PMID: 16766781

    Conclusions: Diet changes that increase renal NAE are associated with increases in serum PTH, bone resorption, and calcium excretion over a 60-day period.

    An ecologic study of dietary and solar ultraviolet-B links to breast carcinoma mortality rates.
    Grant WB.
    Cancer. 2002 Jan 1;94(1):272-81.
    PMID: 11815987

    CONCLUSIONS
    It is hypothesized that animal products are associated with risk for breast carcinoma because they are associated with greater amounts of insulin-like growth factor-1and lifetime doses of estrogen. Vegetable products contain several risk reduction components including antioxidants and phytoestrogens. The association with latitude is very likely because of solar UV-B radiation and vitamin D. Alcohol modulates estrogen's effects on breasts. Fish intake is associated with risk reduction through vitamin D and n-3 oils. These results are consistent with those of many case-control and cohort studies but should be assessed in well designed cohort studies.

    Factors that influence the cutaneous synthesis and dietary sources of vitamin D.

    Vitamin D is rare in food. Among the vitamin D-rich food, oily fish are considered to be one of the best sources. Therefore, we analyzed the vitamin D content in several commonly consumed oily and non-oily fish. The data showed that farmed salmon had a mean content of vitamin D that was ~25% of the mean content found in wild caught salmon from Alaska, and that vitamin D2 was found in farmed salmon, but not in wild caught salmon. The results provide useful global guidelines for obtaining sufficient vitamin D3 by cutaneous synthesis and from dietary intake to prevent vitamin D deficiency and its health consequences.ensuing illness, especially, bone fractures in the elderly.
