Researchers from Northwestern and Harvard report that vitamin D could cut the risk of pancreatic cancer by half.ÂÂ
The new study, published in the journal Cancer Epidemiology Biomarkers & Prevention is the first of its kind to use a large scale epidemiological survey to examine the relationship between the nutrient and this type of cancer.
The study examined data from over 46,000 men aged 40 to 75 who took part in the Health Professionals Follow-up Study and over 75,000 women aged 38 to 65 who took part in the Nurses' Health Study.
Researchers found that people taking the Recommended Daily Allowance (RDA) of vitamin D (400 IU/day) reduced their risk of pancreatic cancer by 43 percent. Less than 150 IU/day of the vitamin was associated with a 22 percent risk reduction.ÂÂ
Further research is needed to determine if vitamin D from dietary sources, like eggs, fatty fish and fortified dairy products or through sun exposure are preferable to multi-vitamin supplements.
