According to the results of a recent study into the effects that higher levels of vitamin D in the blood had on a group of adult Japanese test subjects researchers have stated that elevated levels might help reduce the risk of developing certain types of cancers.
The researchers findings were published today in the BMJ medical journal with results supporting the hypothesis that vitamin D has protective effects at many different sites around the body.
Vitamin D is generated when a person’s skin reacts to sunlight it has been proven to keep bones, teeth and muscles healthy.
While there has been evidence for years as to the benefits Vitamin D has on a person’s bones there is now some new evidence that it may also protect against certain types of chronic diseases, including some types of cancers as well.
It was noted that Vitamin D concentrations can vary depending on a person’s ethnicity and even though studies have already been conducted in the United States and Europe the combined efforts of 6 Japanese medical schools set out to study if vitamin D could lower the risk of cancers in Asian people.
As part of their research a total of 33,736 men and women’s data from public records was analyzed.
Once the study began participants supplied information such as lifestyle, medical history and diet and had blood samples taken to measure the levels of vitamin D in their blood.
The participants were then monitored over a 16 year period during which time 3,301 cases of cancer were reported.
After adjusting for extenuating risk factors such as smoking and obesity it was found that higher levels of vitamin D was associated with a 20 percent lower cancer risk in both men and women studied.
The risk of developing liver cancer fell by 50 percent according to the results published today.
However researchers said that vitamin D did not have any effect on reducing the risk of both lung and prostate cancer.
Previous studies into a deficiency of vitamin D have been linked to increased risk of contracting conditions such as heart disease, colorectal cancer, depression, Alzheimer’s disease among others.
If this recent study is anything to go by it might be time to hit the beach and soak up some rays for the sake of your health, but remember to always use sun cream.
