This time of the year offers an abundance of fresh and in-season fruits and vegetables for every taste bud.1 Eating sufficient amounts of fruits and vegetables can help lead to a healthy lifestyle. However, it is also important to note which of these fruits and vegetables may interact with warfarin, either because of the vitamin K content or by other means. 

Purchasing and eating in-season fruits and vegetables is a good way to enjoy fresh foods anytime of the year. Some in season vegetables low in vitamin K are butternut squash, potatoes, and radish. Asparagus, broccoli, kale, leeks, and turnips are high in vitamin K. Avocado is another beneficial vegetable that has a medium amount of vitamin K. Although it is safe to eat, there may be possible warfarin interactions with avocado, see our article on avocadofor more information.2

Although in-season fruits are not as plentiful as vegetables this time of the year here are some that you may find at your local grocery store. Kiwi is an in-season fruit that is high in vitamin K, it is important to talk with your doctor before eating this fruit. Oranges and pineapple are abundant this time of the year and contain low amounts of vitamin K.2

For more information about the amount of vitamin K in the foods and beverages you consume, check out our Vitamin K Finder. Vitamin K content can vary even within the same piece of fruit or vegetable. Some foods, like iceberg lettuce, are listed as low, medium and high vitamin K content in our Vitamin K Finder for this reason.

It is important to talk with your doctor about starting any new foods because they can interact with your warfarin, so please keep this in mind when planning your next meal.
