What kind of lettuce Pellicle? I use iceberg (low vitamin k) with heart of romaine.
I would love to indulge in mixed greens and butter lettuce. Both high vitamin k.
Also I love avocado but I avoid because of vitamin K. I bought a book called “the Coumadin cookbook” . Written for warfarin patients last edition 2005. It says BEWARE OF AVOCADO. It says vitamin k content in it can vary as much as 40 times! And that small amounts can alter INR.
