Yes: If you are on coumadin, (warfarin) foods rich in vitamin k reverse the therapeutic effect of the medication.Green leafy vegetables, vitamin k supplements make Coumadin (warfarin) less effective. Ask your doctor monitoring your level of anticoagulation for full list.

It depends: If you are taking coumadin/warfarin for your blood clots, the ability to maintain the drug within the therapeutic window can be affected by the foods you eat. This is true of green leafy vegetables such a spinach. To avoid these swings in your drug level while still eating these vegetables, some nutritionists recommend eating a consistent amount of them on a daily basis.

Only if....: ...You are on warfarin, then you want to avoid foods rich in vitamin k.
