It seems like someone somewhere is always involved in a study directed at human health. Some of these studies make front page news… some do not. Here’s one that should be on the front page.

In a recently published study, researchers working

at the University of Oxford, shows the extent to

which vitamin D interacts with our DNA.  

Vitamin D deficiency is linked to a host of health issues including some cancers, rheumatoid arthritis. lupus, MS and autoimmune system disorders.

Of further note is that about 70% of adults and children here in the U.S. are deficient in vitamin D levels.

Working against adequate levels of vitamin D in our population is the fact that this vitamin is only found in very few of our current food sources. The best food sources for vitamin D are oily fish like salmon, tuna and mackerel. Other D vitamin sources include egg yolks, vitamin fortified milk and some varieties of mushrooms.

But the all-around best, most reliable source is sunlight. The problem here is an obvious one. Our dermatologists tell us to use a strong sunblock when sun exposure is on the days’ itinerary. Sunblock prevents vitamin D delivery. And sunlight gets the blame for skin cancer.

Skin cancer is a major problem in the U.S. Here’s what is posted on

  • Skin cancer is the most common form of cancer in the United States. More than 3.5 million skin cancers in over two million people are diagnosed annually
  • Each year there are more new cases of skin cancer than the combined incidence of cancers of the breast, prostate, lung and colon.
  • Treatment of non-melanoma skin cancers increased by nearly 77 percent between 1992 and 2006.
  • Over the past three decades, more people have had skin cancer than all other cancers combined.


As a personal note: I have survived 5 cases of melanoma, 3 basal cell carcinomas and more than a dozen squamous cell cancers. Since February, 2013 I was diagnosed with 5 squamous cell lesions. Two of the “rookie” squamous troublemakers were treated with a prescription topical cream, and the rest required surgery.

I rely on daily vitamin D supplements. More specifically I take 4,000 units of Vitamin D3. You can request a simple blood test called, the 25-hydroxy vitamin D test from your health care provider.

“Our study shows quite dramatically the wide-ranging influence that vitamin D exerts over our health,” says Dr Andreas Heger from the MRC Functional Genomics Unit at Oxford, one of the lead authors of the study.
