Vitamin D 'reduces cancer risk'

13 September 2006

Increasing vitamin D intake could reduce the risk of pancreatic cancer, according to findings in the US.

Scientists concluded that people who consumed 10 micrograms (or 0.01mg) of the vitamin per day appeared to reduce the risk of developing pancreatic cancer by 43 percent.

Vitamin D can be found in a wide range of food including fish, eggs and liver and is also produced when the skin is exposed to sunlight.

The study, conducted at Northwestern University and Harvard University, also found that people who consumed less than four micrograms a day had a 22 percent lower risk of developing pancreatic cancer.

Dr Halcyon Skinner, the lead author of the study, explained that the lack of effective screening for pancreatic cancer meant that it was essential to identify potential preventive measures.

Dr Skinner added: "Vitamin D has shown strong potential for preventing and treating prostate cancer."

He explained that areas with greater sunlight exposure have lower incidence and mortality for prostate, breast and colon cancers, which has led the researchers to investigate a role for vitamin D in pancreatic cancer risk."

"Few studies have examined this association," he said, "and we did observe a reduced risk for pancreatic cancer with higher intake of vitamin D."

Most people get enough vitamin D in their diet and from sunlight on their skin, but certain groups are recommended to take a 10 microgram vitamin D supplement. These include pregnant and breastfeeding women and older people. Other people who should consider a daily 10 microgram vitamin D supplement include:

  • people of Asian origin
  • those who always cover up completely when outdoors
  • those who rarely go outside
  • people who eat no meat or oily fish
