Throw your ideas out the window and go back to eating the vegetables as you always have. The Coumadin will have to be adjusted for the extra K, but so what. Eat the normal diet you usually eat and don't try playing the game of dieting the dose, dose the diet instead. I eat lots of high vit k vegetables nearly daily. There is no reason to stop doing anything differently besides some silly person telling you that you can't do it. Broccoli, Spinich, Lettuce, Brussel Sprouts, you name it, I eat it and a whole lot more then they say to also. If you read the Coumadin Cookbook, your allowed 5 Brussel sprouts per serving. Not this boy, I settle for 10 or 12 as a serving.
Don't plan meals out of a chart either, it won't work!!! You can use the charts for a reference number, but outside of that, forget them completely.
Bottom line---Do NOT modify the diet. Continue to eat as you always have. Just don't suddenly eat a whole bag of spinich or do some crazy off the wall binging on High K items.
