Vitamin K Linked to Decreased Risk of Non-Hodgkin Lymphoma
A study was recently presented at the 101st Annual Meeting of the American Association for Cancer Research (AACR) which found that vitamin K may slash the risk of developing Non-Hodgkin lymphoma.
Non-Hodgkin Lymphoma is a life threatening disease that affects white blood cells and causes tumorous growths. According to the American Cancer Society there are 50,000 new cases of Non-Hodgkin lymphoma in the US every year.
The study was conducted by researchers from the Mayo clinic and included 603 participants with Non-Hodgkin lymphoma and 1,007 healthy control subjects with no cancer.
All of the participants completed food questionnaires in order to determine intakes of vitamin K both from food sources and supplements.
Based on the data the researchers were able to determine that people with high intakes of vitamin K (over 108 mg) had a 45% reduced risk of developing Non-Hodgkin Lymphoma. This protective effect was apparent when vitamin K was consumed through normal dietary sources as well as from supplement sources.
Vitamin K has been receiving an increasing amount of attention due to various other health benefits ranging from bone and joint health to reducing the risk of prostate cancer.
Due to all of these new findings, experts are urging the creation of new daily recommendations for vitamin K, which actually comes in two main forms: K1 (phylloquinone) and K2 (menaquinones). Vitamin K1 is found in green leafy vegetables and makes up about 90% of the vitamin K consumption in a western diet.
Vitamin K2 is harder to come by and therefore makes up only 10% of consumption. It is most common in fermented foods like cheese but can also be found in meat and soybeans. Both vitamin K1 and K2 can also be found in supplement form.
