Vitamin K1 related to blood sugar control in both men and women

Jul 31, 2008

.

     Researchers at the Jean Mayer USDA Human Nutrition Research Center at Tufts University in Boston write that evidence indicates that Vitamin K may be involved in the control of blood sugar but there is no observational data so far on the associations between vitamin K intake and insulin sensitivity.
     They examined the association of vitamin K1 intake with insulin sensitivity and glycemic (blood sugar) status in the Framingham Offspring Cohort. Dietary and supplemental Vitamin K1 intakes were assessed by using a food-frequency questionnaire. It was found that higher K1 intake was associated with greater insulin sensitivity and glycemic (blood sugar) status. The study is published in the July 2008 issue of the American Journal of Clinical Nutrition.
