Health Benefits of Natto

5. Thins Your Blood to Reduce Heart Disease Risk

As mentioned, natto can be helpful in preventing heart disease, but in particular, it works by thinning your blood. The nattokinase enzyme breaks down a substance called fibrin in your blood to help make red blood cells less sticky. The result is that they are less likely to stick to the walls of arteries and turn into plaque. Long term, this can help reduce the risk of heart attacks and strokes since plaque is the number one cause of both.
