Only from my own experience with dear f-i-l:

Onions are listed under foods that are low in vitamin K.
http://www.heartpoint.com/coumadin.html

My f-i-l has been taking coumadin for 15 years now. He has his blood tested
constantly. Everytime he sees a dentist even, he has his blood tested. He
has never been warned about eating onions. He has loads of doctors (top
notch mostly) and has been under dietary care for years now.

BTW, he loves onions.
