A study published in Nutrition, Metabolism and Cardiovascular Disease, 28 February, 2009, found vitamin K consumption to strongly reduce the risk of coronary heart disease. This finding surfaced with an analysis of a cohort study, Prospect-EPIC, consisting of 16,057 women aged between 49 and 70, none of whom had cardiovascular disease at the start of the study. To the surprise of many, those who got their vitamin K from plant forms by eating lots of leafy vegetables did not fare better than the normal population. However, those women who got their vitamin K from animal sources like whole eggs, cheese, goose liver, and animal fats had substantially reduced incidence of cardiovascular disease.

Unfortunately, the researchers are calling for vitamin K2 supplementation not a healthy diet consisting of animal products, which would yield a whole host of other health benefits.

An analysis of the Prospect ? EPIC cohort, which consisted of 16057 post menopausal women between the ages of 49 ? 70, found vitamin K reduces the risk of cardiovascular disease (CVD). None of the participants had CVD at the start of the study. Those who got their vitamin K by eating leafy green vegetables had the same risk of CVD as the general population. Those who obtained their vitamin K by eating whole eggs, cheese, goose liver, and animal fats had a substantially reduced incidence of CVD when compared to the general population.
