Ask Dr. Gourmet

Why should Coumadin (warfarin) users avoid frozen meals?

What does avoiding eating frozen foods have to do with being on Coumadin?

Dr. Gourmet Says...

Vitamin K is not listed in the Nutrition Facts box on frozen food packages (indeed, it is not on any food), as food manufacturers are not required to report the amount of that vitamin, and consequently do not test for its presence.

Because of this you can't know for sure how much Vitamin K you are consuming when eating convenience meals. I tell my Coumadin patients to avoid eating frozen and other convenience foods for this reason: your doctor may feel differently and you should follow their guidance.

Thanks for writing,
