It has a unique smell, but with the passage of time, this smell will gradually disperse and become a softer taste. Natto is a traditional Japanese food, which is made from soybean through the action of similar enzymes. It has the functions of good solubility, improving immunity, regulating metabolism, promoting intestinal peristalsis and facilitating defecation. So natto and stinky beans are different.
