Natto is a traditional Japanese food made from fermented soybeans. It has a unique taste and texture, and is often served as a breakfast food in Japan. While it may not be well-known in western countries, natto has gained popularity in recent years due to its potential health benefits.

What is Natto?

Natto is made by fermenting soybeans with a particular strain of bacteria called Bacillus subtilis. This fermentation process gives natto its characteristic sticky texture and strong flavor. It is often served with mustard, soy sauce, and sometimes over rice. Natto is rich in nutrients such as protein, fiber, and vitamins K2 and B2.

Natto and Longevity

In Japan, natto is often attributed to the longevity of the population. The country has one of the highest life expectancies in the world, and many studies have suggested that the traditional Japanese diet, which includes natto, may play a role in this. Researchers believe that the high nutrient content of natto, especially vitamin K2, may contribute to the health and longevity of individuals who consume it regularly.

Health Benefits of Natto

Aside from its potential role in promoting longevity, natto has been linked to several health benefits. Some of these include:

  • Heart Health: Natto contains a substance called nattokinase, which has been shown to have potential benefits for cardiovascular health. It may help to reduce blood clotting and improve circulation, lowering the risk of heart disease.
  • Bone Health: Natto is rich in vitamin K2, which is important for bone health. Vitamin K2 helps to regulate calcium in the body, promoting strong and healthy bones.
  • Digestive Health: The fermentation process involved in making natto creates beneficial probiotics, which can support a healthy gut microbiome and improve digestion.
