Research Validation of Need for Vitamin D:

(From WorldHealth.NET - Feb 15, 2017)

Study shows that higher levels of vitamin D - specifically serum 25-hydroxyvitamin D - are associated with a reduced risk of cancer.

  • Cedric Garland, DrPH, adjunct professor at the University of California, San Diego School of Medicine and Public Health and member of Moores Cancer Center at UC San Diego Health, and his late brother, Frank, first made the connection between vitamin D deficiency and certain cancers back in 1980.
  • They determined that people residing at higher latitudes, resulting in less sunlight, were more likely to have Vitamin D deficiencies, as it’s produced by the bodies exposure to sunshine. These people also had higher rates of colon cancer. The Garland brothers also found in subsequent studies that vitamin D links to other cancers, including breast, lung, and bladder.

 

A new study, also conducted at University of California, San Diego School of Medicine, and led by Cedric Garland, has found that higher levels of vitamin D, specifically serum 25-hydroxyvitamin D, are associated with a decreased risk of cancer. "We have quantitated the ability of adequate amounts of vitamin D to prevent all types of invasive cancer combined, which had been terra incognita until publication of this paper," said Garland.

"These findings support an inverse association between 25(OH)D and risk of cancer," he said, "and highlight the importance for cancer prevention of achieving a vitamin D blood serum concentration above 20 ng/ml, the concentration recommended by the IOM for bone health."

The Risks and Benefits of Sun Exposure 2016
 
dermoendothumb(From Dermato-Endocrinology - October 2016)

Public health authorities in the United States are currently advising that human sun exposure be reduced.  At the same time, NHANES data show that 32% of Americans suffer from vitamin D insufficiency.

  • Public health authorities in the United States are recommending that men, women and children reduce their exposure to sunlight, based on concerns that this exposure will promote skin cancer. On the other hand, data show that increasing numbers of Americans suffer from vitamin D deficiencies and serious health problems caused by insufficient sun exposure.
  • The body of science concerning the benefits of moderate sun exposure is growing rapidly, and is causing a different perception of sun/UV as it relates to human health. Melanoma and its relationship to sun exposure and sunburn is not adequately addressed in most of the scientific literature. Reports of favorable health outcomes related to adequate serum 25(OH)D concentration or vitamin D supplementation have been inappropriately merged, so that benefits of sun exposure other than production of vitamin D are not adequately described.
  • This review of recent studies and their analyses consider the risks and benefits of sun exposure which indicate that insufficient sun exposure is an emerging public health problem. This review considers the studies that have shown a wide range health benefits from sun/UV exposure.

Key Takeaway:

The message of sun avoidance must be changed to acceptance of nonburning sun exposure sufficient to achieve serum 25(OH)D concentration of 30 ng/mL or higher in the sunny season and the general benefits of UV exposure beyond those of vitamin D.
