The following list summarizes selected foods containing high levels of Vitamin K, as measured by the U. S. Department of Agriculture.
By far, the major source of Vitamin K is green, leafy, vegetables - kale, collards, spinach, and turnip greens are the highest.
Vitamin K aids blood clotting, protects the heart, and helps to build bones.
Those who need to increase their Vitamin K intake can select foods from this high Vitamin K food summary list.
It is not necessary to take Vitamin K supplements, to achieve a high level of Vitamin K nutrition.
Others, who wish to avoid Vitamin K because they are taking Coumadin, may also use the list to help themselves avoid excessive blood thickening. Vitamin K (blood thickener, clotting agent) decreases the action of Coumadin (warfarin - blood thinner, stroke preventer).
Note the profound discrepancies between the U.S.D.A. data, and the Du Pont data handed out at Dominican hospital. This is a serious disconnect.
