Natto is a traditional Japanese food often served at breakfast, alongside miso soup, fish and rice. Like tofu and tempeh, natto is a whole food form of soybean. It’s made by soaking whole soybeans, then steaming or boiling them. Next, the bacteria Bacillus subtilis is added, then left to ferment. Natto has an interesting smell, taste and texture. It looks similar to a small, sticky bean and smells like old cheese. Natto is an acquired taste, but it offers many health benefits. Natto nutrition contains copper, iron, magnesium, calcium, potassium, zinc, selenium and phosphorus. Thanks to these nutrients, along with the powerful probiotics it contains, natto benefits include the ability to prevent kidney stones, boost brain health, improve digestive health and more. (1)
