A traditional fermented Japanese soybean food known for its unique stickiness and distinctive aroma
What is natto?
Natto / fermented soybeans (納豆 in Japanese) are soybeans fermented with natto bacteria after being softened by boiling or steaming, known for their distinctive ammonia aroma generated by the break down of proteins and their overall stickiness when stirred. Natto pairs well with carbohydrates such as rice, bread, and noodles, but is also enjoyed on its own.
Nutrition facts
Natto has extremely high nutritional value. In addition to protein, it is rich in ingredients that are beneficial to overall health, including dietary fiber that contributes to intestinal health, calcium and vitamin K that help keep bones healthy and potassium that aids in stabilizing blood pressure. These fermented soybeans also contain magnesium that keeps blood vessels healthy, iron that prevents anemia and various other crucial nutrients including zinc, molybdenum, vitamin B2, folic acid, niacin, vitamin B6, pantothenic acid, and biotin. In addition, due to undergoing fermentation, natto has a higher digestibility than boiled soybeans.
Nattokinase, an enzyme derived from bacillus subtilis (natto bacteria), is anticipated to improve peripheral blood flow. Since nattokinase and B vitamins are sensitive to heat, it is best to consume natto without heating to maintain maximum nutritional value.
Storage to prevent food loss
Must be stored in the refrigerator. Can be frozen if sealed in an airtight storage plastic bag, then moved to the refrigerator the day before use to slowly thaw, preserving the flavor and nutrients.
Trivia
Natto bacteria are highly resilient and fast-growing. It is said that this bacteria can quickly dominate a soybean-containing environment, readily turning all soybeans into natto.
The vitamin K contained in natto may interfere with the effectiveness of certain blood-thinning medications. Please consult your doctor if you are taking any medications that could interact with natto.
