Valentine’s Day & Your “Warfarin Diet”

Valentine’s Day is a great day of the year to show your loved ones how much you mean to them and of course to spoil them with chocolates and often nice dinners. Valentine’s Day delights are full of drinks and foods, such as wine and dark chocolate, that you should be able to enjoy, even when you are taking medications such as warfarin.

Although there is no specific “warfarin diet”, it is important to watch what you eat as some foods and beverage can change how warfarin works. It is important to maintain a consistent diet.1 You should not see vitamin K as the enemy nor should you avoid eating foods that are high in vitamin K. Most foods with vitamin K are healthy food choices, and may play important roles in the body such as healthy bone maintenance.1 Some foods and drinks you consume during Valentine’s Day may contain vitamin K or other ingredient that may affect warfarin.

Dark chocolate, for example, contains a higher number of calories (1 serving size is 3 squares or 1.5 ounces and contains approximately 180 calories). Is dark chocolate safe to eat while you are on warfarin? Dark chocolate consumption has shown to have many positive effects, such as blood pressure and cholesterol reduction.

Be consistent this Valentine’s and talk to you doctor before making any changes in your diet.
