Siddhart and Aini are both correct. Vit K is PRO-thrombotic. If anything, it might increase any potential blockage. But that is all theoretical because you need those vitamins as part of a healthy diet. For example, the dark green leafy vegetables are also a good source of folic acid. And that might be beneficial in making your vessels more compliant. The only way, therefore, that eating vegetables rich in vitamin K (and folic acid) may help you is if you also avoid animal or saturated fats and so lower your cholesterol. But if you have a calcified plaque, even that may not be sufficient. But it is the combination of a plaque AND and clot in the coronary artery that is usually responsible for a heart attack. Take home message: what you re saying is nonsense. Believe it if you want. But you will not be protecting yourself from heart disease. As for your ridiculous conspiracy theory, if you really believe that doctors have the secret cure for heart disease, HIV/AIDS, cancer or whatever, then you have a medical condition called paranoia. And the next time you get ill or injured, I would dearly love to see whom you seek out for care.
