Mom had massive p embolism & blood clot in leg due to leg procedure dr put on coumadin (warfarin) & told to eat normal is that right ie vitamin k

Yes: I usually tell patients starting warfarin to continue their usual eating habits. When people try new diets, that is when the warfarin effect will change. How much vitamin K one eats is less important than keeping it consistent. So don't try a new salad diet for example, and don't try cutting out all vitamin K either. Just keep intake steady, which is easiest when following usual diet.

Not entirely: As you already inferred, warfarin (Coumadin) is antagonized by certain foods. Usually we refer to these foods as "leafy vegetables": lettuce, brussel sprouts, cabbage, spinach, etc. Ingestion of these may unintentionally "thicken" the blood as it were, in other words make Coumadin less effective. There are differing thoughts on eating healthy while taking Coumadin. You should discuss this with MD
