For a patient on coumadin, which foods should be consistently included in their diet?

For a patient on Coumadin (warfarin), it is essential to maintain a consistent intake of foods that are high in vitamin K, as this vitamin plays a critical role in blood clotting and can affect the medication's efficacy. Spinach and collard greens are both rich sources of vitamin K.

By consistently including these foods in their diet, patients on Coumadin can help maintain stable INR (International Normalized Ratio) levels, which is crucial for avoiding complications associated with both under- and over-anticoagulation. This consistency allows healthcare providers to better manage the warfarin dosage, ensuring that patients achieve the desired therapeutic effect without increased risk of bleeding or clotting.

In contrast, the other food options listed contain varying levels of vitamin K or are not typically considered significant sources. Therefore, while they can be part of a balanced diet, relying on them would not provide the necessary vitamin K consistency needed for a patient on Coumadin.
