An optimum Vitamin D intake lowers the mortality rate
25.02.2011 08:16:47 - Scientists recommend moderate sun exposure and the use of nutritional supplementation to meet vitamin D requirements
(live-PR.com) - Vitamin D deficiency can lead to serious, often fatal diseases, including numerous forms of cancers, cardiovascular disease, diabetes, infections, autoimmune diseases, osteoporosis, dementia and heart failure. The mortality rate could be reduced by up to 24 percent if the population was to have an optimal intake of vitamin D, believed to be a value of 105 nano-molecules per litre of
blood (105 nmol/L). These findings come from a study published in the “Scandinavian Journal of Public Health” professional journal, carried out by a research group from the five Northern European countries of Denmark, Finland, Iceland, Norway and Sweden and led by William B. Grant, one of the world's most renowned experts in the field of vitamin D research. To ensure that the population has an optimal vitamin D intake, experts recommend moderate exposure to sunlight, either through spending time outdoors or by using sunbeds, together with the use of dietary supplements. “In particular, the crucial role played by sunlight exposure in ensuring an optimal vitamin D level should be emphasised to a greater extent in health policy recommendations”, said William B. Grant on the results of the study.
In their study, the research group determined the effect of an increased vitamin D intake on the mortality risk, based on the existing research findings and using the example of the five North European countries mentioned. An average vitamin D level of at least 70 nano molecules per millilitre of blood (70 nmol/L) is scientifically considered to be the value at which the positive effects of vitamin D are seen. Vitamin D production is stimulated by UV radiation with 90 percent of it being produced in the skin.
The Sunlight Research Forum (SRF) is a non-profit organisation based in the Netherlands. Its aim is to make the latest medical and scientific evidence on the effects of exposure to moderate UV radiation available to the general public.

Moan: Health benefit of increased serum 25(OH)D levels from oral intake and ultraviolet-B irradiance in the Nordic countries; Scandinavian Journal of Public Health, 2011; 39: 70–78” can be found on the SRF-Website www.sunlightresearchforum.eu and is available to download.
