Can excessive intake of pineapple increase INR? Plums? I stay between 2.5 & 3.5 because of mitral valve replacement. i regulary eat lots of spinach & broccoli. I stay at around 3.0. Last check was 4.2! What could be the reason? I suspect I had large amount of pineapple juice, strawberries, mango, coconut milk, and plain yogurt. I take 10mg daily.
