Hi! I am a nutrition student doing an internship and one of my projects is to revise a Coumadin diet instruction sheet for patients. I was wondering if you could send me a listing of foods high in vitamin K with values i.e. micrograms (mcg). There has been some conflicting information on vitamin K in onions and onion soup. Any information you could send would be appreciated! Thank you.
Onions are OK for persons on Coumadin except for green or Spring type onions. Onion soup is most often made with yellow or white onions so it should be fine. A few green onions slices sprinkled on the top would not be a problem either.
Here is a table of vitamin K values (micrograms per serving) which you can also get from the USDA. I have selected foods high in vitamin K that people usually consume (excluding spices and herbs which are used in very small amounts). The Recommended Dietary Allowances for vitamin K for adult males is 120 mcg and for adult females 90 mcg.
Table: vitamin K in 1 cup serving:
