To get us started off, here's the link to a section of the database of food nutrients that is maintained by the USDA (United States Department of Agriculture). This particular link is an extract of the full database that is sorted to show foods in order of Vitamin K content:
https://www.ars.usda.gov/SP2UserFiles/Place/12354500/Data/SR24/nutrlist/sr24w430.pdf.
The link to the full database which shows all nutrients is:
https://www.ars.usda.gov/Main/site_main.htm?modecode=12-35-45-00
When looking at this data, be aware that Vitamin K is reported as micrograms (mcg) per serving. The recommended daily allowance (RDA) for Vitamin K is 100 mcg so you can see from the chart that it is quite easy to overload. A few weeks ago, I inadvertently 'overdosed' on spinach when I consumed a whole supermarket pack of 250 grams, the equivalent of over 20 times that RDA. The following paper describes how this would have effected my standing INR:

I'll also post this link in a separate post for easy reference.
Note that all the USDA data is freely available in various data formats suitable for importing into other lists. My suggestion is that we lobby myFitnessPal (mFP) to use this source to add Vitamin K their existing database. Note that another option is to ask mFP to add a feature to enable us to gradually add the Vitamin K data manually. This, however, would still necessitate mFP tweaking the structure of the existing system to allow a) Vit K values to be inserted and b) To ensure that said data is incorporated into the various calculations that drive the display of calorie and nutrient contribution from each day's meals.
I will post any more articles about the general subject of warfarin - research papers, warfarin-friendly diets, etc. and I encourage everyone to do the same.
