HEALTH TIP: Vitamin K May Lower Lymphoma Risk Word from the Mayo Clinic is that people whose diets provide higher levels of vitamin K have an approximately 45 percent lower risk of developing non-Hodgkins lymphoma, an immune system cancer, than those whose K intake is lowest. The investigators compared food questionnaires from 603 newly diagnosed patients with the disease as well as from 1,007 cancer-free controls. The questionnaire asked about the intake of 120 food items two years prior to the cancer diagnosis or enrollment in the study. The researchers also asked about a variety of supplements in order to estimate overall vitamin K intake. The team leader described the findings as fairly strong but cautioned that they need to be confirmed by further studies. The data showed that increasing intake of K via supplements was protective, but that the highest intake from supplements provided no extra advantage, suggesting that taking high doses isn’t likely to be helpful. Good dietary sources of K include leaf lettuce and spinach.#dherbs
