Should I avoid foods with vitamin K if I'm taking warfarin?

Warfarin (Coumadin) is an anticoagulant or "blood thinner." Anti means against, and coagulant refers to blood clotting.  An anticoagulant helps reduce the risk of clots forming in the blood. Many foods you eat have vitamin K in them and vitamin K helps your body make clots. Foods that are high in vitamin K include leafy green vegetables, and some peas and beans. Foods with vitamin K do not need to be avoided if you are on warfarin, but it is important for you to keep your diet consistent.
