I am on Coumadin and I have diabetes. I am told that I can't have grapefruit. Why not?

Dr. Gourmet Says...

Grapefruit and grapefruit juice can interact with many medications. A recent Dr. Gourmet Health and Nutrition Bites discusses this topic and should answer your question. You can read it online at http://www.drgourmet.com/bites/0531.htm. The daily Dr. Gourmet Newsletter covers such diverse topics as this as well as information on supplements and new research on diet and nutrition. You can sign up on the home page.

Thanks for writing.
