Sun exposure reduces pancreatic cancer risk by nearly 50 percent

The health benefits of vitamin D are almost becoming too numerous to count, with  yet another new study presented at the recent American Association for Cancer  Research Pancreatic Cancer Conference in Lake Tahoe, Nev., shedding light on  the hormone’s specific anti-cancer benefits. According to the groundbreaking  research, individuals exposed to natural sunlight, which is the most abundant  source of natural vitamin D, are nearly 50 percent less likely to develop  pancreatic cancer than others who are not exposed.
Dr. Rachel Neale,  Ph.D., and her colleagues from the Queensland Institute of Medical  Research in Brisbane, Australia, conducted a case-control study in which 704  patients with pancreatic cancer, and 709 healthy individuals with no history of  pancreatic cancer, were evaluated based on blood serum levels of 25-hydroxy  vitamin D, the hormonal marker of vitamin D in the body. Each individual’s birth  location, skin cancer history, skin cancer type, tanning ability, and  predisposition to sunburn was also taken into account.
The team then used  NASA’s Total Ozone Mapping Spectrometer to assess each participant’s level of  ultraviolet (UV) radiation exposure to his or her birthplace, the data of which  was used to place participants into various tertile groups for average UV  radiation exposure. At the end of the day, researchers found that participants  who lived in areas with the highest amount of sunlight exposure were 24 percent  less likely to develop pancreatic cancer than individuals who lived in low  sunlight areas.
Additionally, individuals with the most sun-sensitive  skin, who are typically lighter-skinned individuals, were found to be roughly 50  percent less likely to develop pancreatic cancer than individuals with the least  amount of sun sensitivity. Overall, there was a direct correlation between high  sunlight exposure and low rates of pancreatic cancer in the study, a result that  suggests vitamin D plays a critical role in pancreatic cancer  prevention.
“High levels of vitamin D are associated with a lower risk of  pancreatic cancer based on both observational studies of individuals and  geographic studies of populations,” writes the Vitamin D Councilon their  website. “Based on studies of breast, colon, and rectal cancer, vitamin D levels  above 40 ng/mL (100 nmol/L) reduce the risk of cancer. Thus, maintaining vitamin  D blood levels above 40 ng/mL may reduce the risk of pancreatic cancer.”

Why vitamin D is crucial for vibrant health

Vitamin D, which is  actually a pro-hormone, actually plays an important role in regulating the  entire human genome. 1,25-dihidroxyvitamin D, also known as calcitriol, is  responsible for unlocking the more than 2,700 genetic binding sites specifically  designed for it that are located throughout the human body. And every single one  of the genes affected by calcitriol plays a role in the onset of most major  human diseases.
What this means is that vitamin D deficiency can cause  all sorts of illnesses, including everything from simple colds and influenza to  chronic diseases like heart failure and cancer. And since vitamin D can really  only be obtained in adequate amounts through natural sunlight or supplementation  with high doses of vitamin D3, it is crucial that every individual pay close  attention to his or her vitamin D levels.
The best way to obtain vitamin  D is through natural sunlight exposure. A fair-skinned person can produce enough  vitamin D from about 15 minutes of direct sunlight exposure during the peak  summer months, while a darker-skinned person may need as much as an  hour-and-a-half of sunlight exposure. Sunscreens are designed to block out the  UV rays responsible for vitamin D production in the skin, so it is important not to wear sunscreen when trying to obtain vitamin D from the sun  (
Another option is to  supplement with vitamin D3. The government’s recommended daily amount (RDA) for  vitamin D is still too low, as most people need to take anywhere from 1,000 –  10,000 international units (IU) of vitamin D3 every day to maintain adequate  blood levels. If you are unsure about your vitamin D levels, you may wish to  have a blood test taken to determine what is an appropriate amount of vitamin D  with which to supplement (
