But eating too many of them can actually pose a risk to your health.

Vitamin K

Brussels sprouts contain vitamin K, which is a chemical the body uses to promote blood clotting.

According to the NHS, adults need approximately 1mcg a day of vitamin K for each kilogram of their body weight.

Someone who weighs 65kg would need 65mcg a day of vitamin K, while a person who weighs 75kg would need 75mcg a day.

However, vitamin K counteracts the effects of anticoagulants (blood thinning medication), which some people may need to prevent the occurence of blood clots.

Mayo Clinic advise that those taking the blood-thinning medication Warfarin should carefully monitor their daily vitamin K intake.

Their website explains that “Warfarin is a blood-thinning medication that helps treat and prevent blood clots.

“However, certain foods and beverages can make warfarin less effective in preventing blood clots. It’s important to pay attention to what you eat while taking warfarin.

“One nutrient that can lessen warfarin’s effectiveness is vitamin K. It’s important to be consistent in how much vitamin K you get daily.”
