    Vitamin D is a fat-soluble steroid hormone precursor that contributes to the maintenance of normal levels of calcium and phosphorus in the bloodstream. Strictly speaking, it is not a vitamin since human skin can manufacture it, but it is referred to as one for historical reasons. It is often known as calciferol. The major biologic function of vitamin D is to maintain normal blood levels of calcium and phosphorus. Vitamin D aids in the absorption of calcium, helping to form and maintain strong bones. It promotes bone mineralisation in concert with a number of other vitamins, minerals and hormones. Without vitamin D, bones can become thin, brittle, soft or misshapen. Vitamin D prevents rickets in children and osteomalacia in adults -- skeletal diseases that result in defects that weaken bones. This book gathers international research on the leading-edge of the scientific front.

New Research by D*action Member Dr. Cedric Garland Suggests Role Low Levels of Vitamin ... - 0 views

    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."

New Hot Paper Comment by Bruce W. Hollis - 0 views

    Vitamin D deficiency is a very serious health problem. Most people tend to think of it only in terms of skeletal problems; however, it is much more than that. Vitamin D deficiency has now been linked with a multitude of neoplasms, autoimmune dysfunction, compromised innate immunity and neurodevelopment in utero. Vitamin D is made in huge amounts when we go into intense sun. A fair-skinned individual can produce approximately 20,000 IU in 10 minutes' time with a total body exposure. A person with significant pigmentation will require up to 10 times the exposure to make an equivalent amount. In the winter at the latitude of Chicago, even a fair person cannot photo-produce vitamin D from mid-October through March. Thus, it is VERY important to have a realistic vitamin D recommendation as the current 200 IU/day recommendation is a joke

Does vitamin D protect against cancer? « Cancer Research UK - Science Update - 0 views

  •  
    This month, the authoritative International Agency for Research into Cancer (IARC) have weighed in on the issue. By gathering a group of expert scientists, they have looked at all the available evidence and published a detailed report on vitamin D and cancer. The massive tome weighs in at 465 pages, but we'll take a look at the key points in the first of two posts looking at the vitamin D debate.

    It is impossible for us to get more than about five percent of the vitamin D we need from our diet - unless, like Eskimos, we eat oily fish three times a day.

Researchers who touted high vitamin D doses shut out of panel - The Globe and Mail - 0 views

    The panel selected to analyze the health claims is being criticized for not including the medical researchers whose work prompted intense scientific interest in the nutrient in the first place.

    "If you were publicly in favour of vitamin D, you were not included, and I find that outrageous," said Reinhold Vieth, a professor in the department of nutritional sciences at the University of Toronto, and one of Canada's leading experts on the nutrient.
