Vitamin K benefits the heart

New research has found that people who eat a diet rich in vitamin K have a lower risk of conditions affecting the heart or blood vessels

The new study looked at 50,000 people over 23 years and found that people who eat a diet rich in vitamin K have an up to 34% lower risk of illnesses related to plaque build-up in the arteries, also known as atherosclerosis-related cardiovascular disease. 

There are two types of vitamin K in foods we eat: vitamin K1 and vitamin K2. Vitamin K1 comes primarily from green leafy vegetables such as kale, while vitamin K2 is found in meat, eggs, and cheese. 

The researchers think that vitamin K might protect against the calcium build-up in the body’s major arteries.
