Natto has a long and fascinating history that dates back over a thousand years in Japan. As a traditional food, it is deeply rooted in Japanese culture, enjoyed for its unique taste and health benefits.
There are a few legends about how natto came to be. One popular story suggests that it was accidentally discovered by a group of Japanese samurai warriors. After boiling soybeans for their meal, the samurai were suddenly called into battle, leaving their beans behind. When they returned days later, they found that the soybeans had fermented, creating the first-ever batch of natto.
The fermentation process for natto utilizes a specific type of bacteria called Bacillus subtilis. In ancient times, people likely stumbled upon this bacteria because it is naturally present in straw, which was used to store and transport soybeans. The interaction between the bacteria and the soybeans, combined with water and heat, resulted in the creation of natto, with its distinctive taste, texture, and aroma.

As you explore the world of natto, you’re not only enjoying delicious and nutritious food but also taking part in a culinary tradition that has been cherished for over a millennium.

Natto is fermented with Bacillus subtilis natto, a type of probiotic bacteria that supports gastrointestinal health. Probiotics help maintain a healthy balance of good bacteria in the gut, which can improve digestion, boost the immune system, and contribute to overall well-being.

Natto contains an enzyme called nattokinase, which has been found to support cardiovascular health. Nattokinase helps break down blood clots and may lower blood pressure, reducing the risk of heart disease and stroke.

Natto is a rich source of vitamin K2, which plays a crucial role in bone health. Vitamin K2 helps the body use calcium effectively, promoting strong bones and reducing the risk of osteoporosis.

Natto is packed with essential nutrients including protein, dietary fiber, vitamins, and minerals. It contains vitamins B2, B6, and E, as well as minerals like calcium, iron, magnesium, and potassium.

Soybeans, the main ingredient of natto, are rich in isoflavones. These plant compounds have been linked to various health benefits, such as reducing the risk of certain types of cancer, improving menopausal symptoms, and supporting heart health.

The dietary fiber in natto can help with weight management by promoting a feeling of fullness and aiding in digestion. This may help with appetite control and prevent overeating.
