How does nattokinase contribute to Japanese longevity. What are the health benefits of consuming natto. Why is nattokinase considered a powerful fibrinolytic enzyme. How can nattokinase potentially prevent cardiovascular diseases.

The Discovery of Nattokinase: A Breakthrough in Thrombosis Research

In the realm of medical research, few discoveries have been as serendipitous and impactful as that of nattokinase. This powerful enzyme, found in the traditional Japanese food natto, has revolutionized our understanding of natural fibrinolytic agents and their potential in preventing and treating cardiovascular diseases.

Dr. Hiroyuki Sumi, affectionately known as “Dr. Natto,” stumbled upon this remarkable enzyme in 1980 while conducting research on thrombosis in Chicago. His curiosity led him to test natto’s effects on thrombus in a laboratory dish, resulting in a surprising discovery that would change the course of his career and contribute significantly to the field of physiological chemistry.

The Serendipitous Experiment

Dr. Sumi’s experiment was simple yet groundbreaking. He applied natto to a thrombus in a laboratory dish, a test typically performed with urokinase, a known fibrinolytic enzyme. The results were astounding – natto exhibited a strong fibrinolytic activity, effectively lysing the thrombus and leaving a large area cleared.

This unexpected finding prompted Dr. Sumi to delve deeper into the properties of natto, leading to years of research and experimentation. In 1986, he presented his findings to the scientific community, introducing the world to the enzyme he named “nattokinase.”

Nattokinase vs. Other Fibrinolytic Enzymes

How does nattokinase compare to other known fibrinolytic enzymes? Dr. Sumi’s research revealed that nattokinase surpasses even medical-grade enzymes in its fibrinolytic activity. Unlike urokinase (derived from human urine) or tissue plasminogen activator (TPA, obtained from cancer cells), nattokinase is entirely natural and food-derived, making it a safer and more accessible option for many people.

• Urokinase: Derived from human urine
• TPA: Obtained from cancer cells (melanoma)
• Streptokinase and staferokinase: Protein components from bacteria
• Nattokinase: Naturally occurring in fermented soybeans (natto)

The superiority of nattokinase lies not only in its potency but also in its safety profile. As a food-derived enzyme, it poses minimal risk of adverse reactions, making it an attractive option for long-term use in preventing thrombosis-related conditions.

The Unique Properties of Natto: More Than Just Nattokinase

While nattokinase has garnered significant attention, natto’s health benefits extend far beyond this single enzyme. This traditional Japanese food is a nutritional powerhouse, offering a complex array of compounds that contribute to overall health and longevity.

Vitamin K2: The Unsung Hero

Alongside nattokinase, natto is one of the richest dietary sources of Vitamin K2. This often-overlooked nutrient plays a crucial role in calcium metabolism, bone health, and cardiovascular function. How does Vitamin K2 complement nattokinase’s effects? While nattokinase works to dissolve blood clots and improve circulation, Vitamin K2 helps to prevent calcium deposits in arteries, effectively providing a two-pronged approach to cardiovascular health.

Antibacterial Properties

Natto’s benefits extend beyond cardiovascular health. Historical records from the Edo period in Japan suggest that natto was used to prevent various infectious diseases, including cholera, typhoid, and dysentery. Modern research has confirmed natto’s antibacterial properties, identifying compounds such as di-picolinic acid that can suppress harmful bacteria like E. coli O157:H7.

These antibacterial properties, combined with natto’s high nutritional value and easy digestibility, explain its historical use in treating various ailments and supporting overall health.

The Versatility of Nattokinase Production

While traditional natto is made from soybeans, Dr. Sumi’s research has revealed that nattokinase can be produced using various legumes and seeds. This versatility opens up new possibilities for nattokinase production and consumption, potentially making it more accessible to people with soy allergies or those following specific dietary restrictions.

Alternative Sources for Nattokinase

1. Black beans
2. Azuki beans
3. Kidney beans
4. Sunflower seeds

Despite these alternatives, soybeans remain the most efficient substrate for Bacillus natto, the bacteria responsible for natto fermentation. The unique protein composition of soybeans appears to facilitate optimal nattokinase production, explaining why traditional natto has been so effective.

The Global Impact of Natto Research

Dr. Sumi’s discovery of nattokinase has sparked worldwide interest in natto and its potential health benefits. As the incidence of thrombosis-related conditions like myocardial infarction and cerebral infarction continues to rise, particularly in countries adopting Western diets, the search for natural preventive measures has intensified.

Natto, with its powerful combination of nattokinase and Vitamin K2, has emerged as a promising food in the fight against cardiovascular diseases. Its long history of consumption in Japan, coupled with the country’s high life expectancy, has led many researchers to investigate the link between natto consumption and longevity.

Natto’s Role in Japanese Longevity

Japan consistently ranks among the countries with the highest life expectancy in the world. While many factors contribute to this longevity, including genetics, lifestyle, and healthcare systems, the traditional Japanese diet plays a significant role. Natto, as a staple in many Japanese diets, may be a key contributor to this longevity.

The combination of nattokinase’s fibrinolytic activity and Vitamin K2’s role in calcium metabolism provides a powerful defense against two major contributors to cardiovascular disease: blood clots and arterial calcification. This dual action may help explain the lower rates of heart disease observed in regions of Japan where natto consumption is highest.

The Future of Nattokinase Research and Applications

As interest in nattokinase continues to grow, researchers are exploring new applications and delivery methods for this powerful enzyme. While consuming natto remains the most traditional and natural way to obtain nattokinase, supplements and fortified foods are becoming increasingly available for those who may not enjoy natto’s distinctive taste and texture.
