What foods cause INR to increase?

Note: Most fruits, meats, starches, dairy products and sweets do not contain high amounts of vitamin K. Consuming large amounts of cranberry juice may increase warfarin levels (so your INR may be higher, and you may be at a higher risk for bleeding).

Keeping this in view, what foods can decrease warfarin activity?

The foods that will potentially cause notable interactions with warfarin are mango, grapefruit, cranberry, and those with high vitamin K content such as certain green leafy vegetables, oils, multi-vitamins, herbal supplements, edible seaweed, avocado, and soymilk.
