Love your food list. I see that green peppers are high in Vitamin K. Does the same hold true for red, yellow and orange bell peppers?
An early version of the food list you're referring to does have a typo with respect to green peppers. Green bell peppers should be listed as Low in Vitamin K. A cup of diced green pepper has only 11 micrograms (mcg) of Vitamin K and this would be considered low enough to be safe. I am sorry for the misunderstanding.
The updated lists can be found at these links:
https://staging.mds.culinarymedicine.org/md/warfarinbrief.pdf - a short list of common foods that are considered High or Medium with respect to Vitamin K. Specific amounts of Vitamin K are not listed.
https://staging.mds.culinarymedicine.org/md/relativewarfarinlist.pdf - a longer list sorted by ingredient name with the relative amounts of Vitamin K (High, Medium, Low).
https://staging.mds.culinarymedicine.org/md/warfarincomprehensive.pdf - Specific amounts of Vitamin K in micrograms in an alphabetical list.
Our most comprehensive list of over 800 common foods and their specific amounts of Vitamin K, sorted both by name and by amount of Vitamin K, is available in the Store for $4.95 for the PDF and $12.95 + s/h for the purse-sized paperback.
Interestingly, yellow peppers contain no Vitamin K (zero) and red peppers only 7 mcg for a large pepper.
