Question: 1 / 400

Which of the following is NOT a common food that may reduce warfarin's effectiveness?

Leafy Greens

Fish

Fish is not a common food that may reduce warfarin's effectiveness because it contains omega-3 fatty acids which are known to have a positive effect on cardiovascular health and do not interfere with warfarin's actions. Leafy greens, vitamin K-rich foods, and dairy products, on the other hand, contain high levels of vitamin K which can counteract the effects of warfarin by promoting blood clotting. It is important for individuals taking warfarin to maintain a consistent intake of vitamin K-rich foods and consult with their doctor before making any major changes to their diet.
