Quizplus · Accepted Answer

Spinach is high in Vitamin K, which can counteract the effects of anticoagulant therapy. It is important for patients on anticoagulant therapy to maintain a consistent intake of Vitamin K, so they should be advised to limit or avoid foods high in Vitamin K, such as spinach. Bananas, tomatoes, and sweet potatoes are not high in Vitamin K and do not have a significant effect on anticoagulation levels.
