Excessive consumption of vitamin K1-rich foods may antagonise the action of warfarin. Eating a large amount of brussels sprouts precipitated hospital admission for a patient who was on anticoagulation therapy for a left ventricular assist device. Doctors should counsel all patients in whom maintenance of anticoagulation is crucial against overconsumption of such foods.
