Natto is a traditional Japanese dish made from fermented soybeans. It has a unique texture and flavor that some people find off-putting, but it is highly regarded for its health benefits and nutritional value. In this article, we will explore the science behind the making of natto and its nutritional properties.
How Natto is Made
The production of natto begins with steamed soybeans, to which a bacterium called Bacillus subtilis var. natto is added. This bacterium ferments the soybeans, producing the characteristic sticky texture and strong smell associated with natto. The fermentation process typically takes around 24 hours at a warm temperature, after which the natto is ready to be consumed.
During fermentation, the bacterium produces an enzyme called nattokinase, which is believed to have health benefits such as improved circulation and heart health. This enzyme also contributes to the unique flavor and texture of natto.
Nutritional Value of Natto
Natto is an excellent source of nutrients, including protein, fiber, vitamins, and minerals. It is particularly high in vitamin K2, a nutrient important for bone health and cardiovascular health. Natto also contains significant amounts of iron, magnesium, and calcium, as well as various B vitamins.
One of the most important nutritional components of natto is its high content of probiotics. The fermentation process introduces beneficial bacteria that can improve gut health and digestion. These probiotics also support the immune system and may have anti-inflammatory properties.
Another unique compound found in natto is polyglutamic acid, which has been studied for its potential health benefits, including antioxidant and anti-inflammatory effects.
Conclusion
Natto is a traditional Japanese dish made from fermented soybeans, and it offers a wide range of health benefits. The fermentation process gives natto its unique texture and flavor, while also producing beneficial compounds such as nattokinase, probiotics, and polyglutamic acid. As a result, natto is a nutrient-dense food that can contribute to a healthy and balanced diet.
