- A. I should avoid them completely during treatment
- B. I should eat a consistent amount from week to week
- C. I should eat a large amount before each test

Green leafy vegetables contain vitamin K, which can reduce warfarin's anticoagulant effect. They do not need to be eliminated, but the amount should remain reasonably consistent so treatment can be adjusted safely.
