Dear Dr. Gourmet,

While taking Coumadin, is it OK to eat iceberg lettuce?

A: Dr. Gourmet Says...

Iceberg lettuce fell out of favor amongst foodies but I have always loved it. It is the one lettuce that doesn't have a lot of Vitamin K. One cup of iceberg lettuce contains only about 13 micrograms (mcg) of Vitamin K. This is a low amount and should be safe for you to use as part of your diet while on Coumadin® (warfarin).

Thanks for writing,

Dr. Gourmet
