A new study finds that a diet high in vegetables, fruit and fish prevents blood clotting and supports circulation.

The study, published in Circulation, studied the eating habits of more than 15,000 adults ages 45 to 64. The people who ate the most fruit, vegetables and fish had the smallest risk of developing a blood vessel clot (thrombus), which can block coronary arteries or cause stroke by disrupting blood flow in the brain. People with diets high in folic acid, vitamin B6 and omega-3 fatty acids were further protected. The risk of thrombosis doubled among people who ate 1.5 or more servings per day of red or processed meat.
