It's almost exclusively the
DARK, LEAFY green vegetables that have lots of vitamin K: spinach, kale, collard greens. Most other vegetables, such as iceberg lettuce, califlower, cabbage, beans, etc., etc., for example, have far less vitamin K content per serving. The rule is not to necessarily avoid dark leafy green vegetables, but to be consistent in your intake. If you eat dark green leafy vegetables every day, continue to do so, or if you eat them once a week, continue that pattern. If you change your eating habits regarding these particular vegetables, your INR could change. On the other hand, if your vegetable intake involves mostly green beans, lettuce, etc., consistency if not that important. I was not a big spinach eater before, so I am not now. Other than the dark leafy green vegetables, I eat whatever vegetables whenever I want and my INR has been extremely stable. And I'll eat SOME spinach SOME times without any issue, just not a huge amount. So, say, if there is spinach scattered on a pizza, I don't get antsy, but I won't have a large spinach salad.
Here is a useful reference table.

I decided that anything below around 100 mcg per serving is not going to do anything significant. Again, that's just my way of dealing with this long list. And even 200 is not enough to do anything measurable. I made a general conclusion that there are only a handful of dark leafy green things have enough vitamin K to have a significant effect.
Also, note the portion sizes. I've seen some reference tables that are very misleading, seeming to indicate iceberg lettuce, for example, has a lot of vitamin K, but they made the mistake of quoting content for an entire head of lettuce. Another list had pie crust high in vitamin K - again, stupidly quoting the content for an entire pie crust. A lot of people just accept that veggies in general are loaded and use these lists without even looking them over to understand them. Even INR clinic staff seem to have a lot of mistaken ideas and give misleading advice.
