A blood clot, also known as thrombosis, can be a life-threatening situation, particularly if a large chunk of a blood clot breaks off and obstructs and artery or blood vessels. Asparagus is a surprisingly effective dietary element that can prevent blood clots, according to recent research. Asparagus contains a particular flavonoid called rutin, which directly inhibits blood clots by preventing platelet aggregation. For those who are at high risk for thrombosis, either through health history or behavioral aspects, adding asparagus to your weekly diet is a very wise choice.
