Researchers at the Mayo Comprehensive Cancer Center in Minnesota, US, report finding that people who have higher intakes of vitamin K from their diet have a lower risk of developing non-Hodgkin’s lymphoma.

In the first study of its kind, the researchers found that the risk of developing non-Hodgkin’s lymphoma was about 45% lower for participants with vitamin K intakes of greater than 108 ug/day, compared with participants who had intakes of less than 39 ug/day. The association remained after accounting for age, sex, education, obesity, smoking, alcohol use and intake of foods with high amounts of antioxidants.

The researchers said vitamin K appeared to be important in the inhibition of inflammatory cytokines thought to play a role in non-Hodgkin’s lymphoma, as well as pathways involved in cell cycle arrest and cell death.
