I use Natto almost daily and it is a food group that most foreigners have difficult eating. In fact, I had a chef to my home who hadn’t tasted it in over ten years but this preparation made him smile and us too.
The Nattokinase is a gooey-sticky food enzyme said to be a blood thinner but there is not real proof. The main issue is the taste which can be considered awful when eaten alone. You actually whip it and it creates strings of bonds and activates the enzmyes and serine proteases. In humans, they are responsible for coordinating various physiological functions, including digestion, immune response, blood coagulation and reproduction.
I prepare it with certain greens, peppers, herbs and veggies to turn a super food into a highly nutritious and active flowing food. While other soy foods contain enzymes, it is only the nattō preparation that contains the specific Nattokinase enzyme.
