Taking coumadin? Limit these foods

Foods high in vitamin K can interact with blood thinning medications so every once in awhile it's okay to pass on the broccoli or spinach.

If you take the blood thinner warfarin (Coumadin®), cardiologists caution against eating too many foods high in vitamin K, which the body uses to clot blood. Foods like those below, which are high in vitamin K, can act as an antidote to your medicine.

  • Broccoli
  • Kale
  • Parsley
  • Spinach
  • Mustard greens
  • Broccoli Raab
  • Cabbage
  • Swiss Chard
  • Romaine and other dark green lettuces
  • Soybean oil

Leafy green vegetables contain the highest amount of vitamin K. You don't have to avoid these foods, but eat them in modest amounts and keep your intake consistent. The key is to try to eat a similar amount of foods that contain vitamin K each day so your blood levels remain stable.

You should also limit the amount of green tea, alcohol, and cranberry juice you drink.
