Position of health organizations and agencies in Australia, Canada, New Zealand, the United Kingdom, and the United States, and the World Health Organization, on UV radiation and vitamin D


It's the great cancer cover-up. Panicked into avoiding sunlight by health experts, we are now dying in our thousands from diseases linked to deficiencies of vitamin D. But still the exaggerated warnings come.

Objectives and approach

The primary objective of SUNARC is to do research on and provide information on the primary prevention of chronic disease through lifestyle and dietary choices.

To this end, SUNARC will conduct research and provide information on (or advance the understanding and acceptance of) ultraviolet radiation, solar and artificial, as an important positive health factor, not only for musculoskeletal diseases, but also for chronic diseases such as autoimmune diseases, cancer, heart disease, multiple sclerosis, and neurological disorders.

The approach will be to have the most comprehensive summary of data, research findings, health policies, and links to information regarding the health benefits of ultraviolet radiation and vitamin D.

In addition, SUNARC will conduct research and provide information about the role of nutrition as risk and risk reduction factors for chronic diseases such as Alzheimer's disease, autoimmune diseases, cancer, heart disease, musculoskeletal diseases, and rheumatoid arthritis.

William Grant has 142 publications on vitamin D listed at as of December 31, 2011, and an additional 17 publications on ultraviolet radiation. To access many of them, go to and enter “Grant W, vitamin D” in the search field. 47 have open access/free download; 21 are reviews. Another 5 papers on ultraviolet have open access. He publishes about 30 articles and letters to the editor each year, so check back often for important updates on ultraviolet B and vitamin D.

The health benefits of ultraviolet-B (UVB) irradiance and vitamin D are coming into sharper focus as more research results are published. There are now about 100 conditions and diseases linked to low serum 25-hydroxyvitamin D concentrations. Documents on about 75 of these diseases and conditions are posted at
