AAD: your Vitamin D should come from diet, not the sun


Thanks for the tip from the Clinuvel Blog. The AAD has issued an Updated Position Statement on Vitamin D.

The AAD’s position is that there is NO SAFE THRESHOLD for sun or indoor tanning exposure, and that we ought to get our recommended daily allowance for Vitamin D from our diet.

This is big news. We are told in the media that we ought to get enough Vitamin D from normal exposure to the sun, but the peak skin health body is now telling us that this is wrong.

The AAD also appears to be taking a very conservative position on the overall importance of Vitamin D in health and thus if any minimum daily allowance should be supported.

Academy Issues Updated Position Statement on Vitamin D

SCHAUMBURG, ILL. (Jan 19, 2011)

The American Academy of Dermatology (Academy) has updated its position statement on vitamin D based on the results of a review of the increasing body of scientific literature on this vitamin and its importance for optimal health recently conducted by the National Academy of Sciences Institute of Medicine (IOM).

The Academy continues to recommend that the public obtain vitamin D from a healthy diet that includes food naturally rich in vitamin D, foods and beverages fortified with vitamin D, and/or dietary supplements. The Academy reaffirmed its position that vitamin D should not be obtained from unprotected exposure to ultraviolet (UV) radiation from the sun or indoor tanning devices, as UV radiation is a known risk factor for the development of skin cancer.

The IOM reviewed the scientific literature examining the possible relationship between vitamin D and certain types of cancers, neurologic disease, infectious disease, autoimmune disease and cardiovascular disease. Based on review of more than 1,000 studies and expert and stakeholder testimony, the IOM concluded that while the evidence for associating vitamin D levels with bone health was strong, the evidence for other conditions was inconsistent, inconclusive and insufficient to inform nutritional requirements.

The Academy’s position statement reflects the IOM’s findings, including the vitamin D blood level deemed adequate and safe for the human body (20 ng/ml), and the Recommended Dietary Allowance (RDA) for calcium and vitamin D intake to support skeletal health. The Academy noted that the RDAs for vitamin D reflect an assumption of minimal sun exposure.

The Academy’s updated position statement also asserts that there is no scientifically proven, safe threshold of sun or indoor tanning device exposure that allows for maximum vitamin D synthesis in the skin without increasing the risk of skin cancer.
