Foods High In Vitamin K To Avoid While On Coumadin
Introduction
Coumadin, also known as warfarin, is a blood-thinning medication used to prevent blood clots. People who take Coumadin need to be careful about their diet because vitamin K can interfere with the medication. Vitamin K is a nutrient found in many foods, and it helps with blood clotting. Therefore, it is important to know which foods are high in vitamin K and should be avoided while on Coumadin.
Foods High In Vitamin K
Foods that are high in vitamin K include dark, leafy greens such as spinach, kale, collard greens, and mustard greens. Other vegetables such as broccoli, Brussels sprouts, and asparagus are also high in vitamin K. Fruits such as blueberries, blackberries, and figs are also sources of vitamin K. Herbs such as parsley, basil, and thyme are also high in vitamin K.
How Vitamin K Interferes With Coumadin
Coumadin works by blocking the action of vitamin K in the body, which prevents blood clotting. However, if you consume too much vitamin K while taking Coumadin, it can interfere with the medication's effectiveness. This can cause blood clots to form, which can lead to serious health problems such as stroke or heart attack.
Recommended Daily Intake of Vitamin K
The recommended daily intake of vitamin K varies depending on age and gender. For adult males, the recommended daily intake is 120 micrograms per day, and for adult females, it is 90 micrograms per day. However, if you are taking Coumadin, your doctor may recommend a lower daily intake of vitamin K to avoid interfering with the medication.
