Natto: Japan's Slimy Fermented Superfood Goes Global 2026

Natto, Japan's slimy fermented superfood, is emerging as a global health trend to rival kimchi, kombucha, and kefir. Despite its pungent smell and viscous texture, this traditional Japanese breakfast staple is winning over health enthusiasts worldwide.

What is Natto?

Natto is made from whole soybeans fermented with Bacillus subtilis, a bacterium that gives it its characteristic slimy texture and strong odor. The fermentation process breaks down the beans' proteins, making them easier to digest and enhancing their nutritional profile.

While many Japanese people avoid natto due to its sensory qualities, it has been a cherished breakfast food for centuries among those who appreciate its unique taste and health benefits.

Origins and History of Natto

The exact origins of natto are unclear. Some believe it was introduced to Japan from China by Buddhist monks during the Yayoi period (300BC-AD300), becoming a rural staple during the Edo period (1603-1868).

A more colorful legend credits Minamoto no Yoshiie, a military commander during the Heian period (794-1185). His troops discovered that simmered soybeans, originally intended for their horses, had fermented in the heat after an enemy sighting. Famished, they ate the beans anyway and liked them enough to offer them to their master, who was similarly impressed.

Nutritional Profile and Health Benefits

Natto is packed with nutrients and beneficial compounds. It is particularly rich in vitamin K2, which supports bone health and cardiovascular function, and nattokinase, an enzyme that may help prevent blood clots.

Additionally, natto is a great source of protein, fiber, and probiotics, which promote gut health. Its fermentation process also increases the bioavailability of nutrients, making it a true superfood.

How to Enjoy Natto

Natto is typically eaten with rice, often mixed with soy sauce, mustard, and green onions. It can also be added to soups, salads, or even pasta for a nutritional boost. If you're new to natto, start with small amounts and experiment with seasonings to find your preferred taste.

Global Availability

Natto is now exported worldwide, packaged in Styrofoam trays with small paper cups and frozen to preserve its nutritional value. Manufacturers ensure that the fermentation process continues to deliver the same health benefits regardless of where it's consumed.
