It's not the prettiest dish, but natto has some powerful health benefits.
When you think of Japanese cuisine, fresh, delicate flavours and intricately presented morsels spring to mind. Amidst all this loveliness, gooey, sticky and stinky fermented soybeans seem somewhat out of place. Called natto, this pungent dish is lesser known in Australia, but it lurks in the freezer section of Asian supermarkets, waiting for adventurous types to seek it out. Craig Anderson, star of My Japanese Diet (screening April 6 on SBS) is one such culinary maverick.
In fact, when SBS Food calls him to chat about the documentary, he’s just finished a bowl of natto on rice – a daily ritual since filming My Japanese Diet, which sees him swap his former diet of burgers, pizza and lollies for traditional Japanese food. “Natto is a food that divides Japan: half of them hate it and half like it,” says Anderson, who maintained his Japanese diet even after cameras stopped rolling. “People complain that natto smells like foot odour mixed with paint thinner, but when I eat it, it tastes like Dijon mustard over cannellini beans and it provides protein and carbs that keeps me going through the day,” he says.
Craig Anderson in My Japanese Diet Craig Anderson tries natto for the first time in Japan.
Natto, a traditional food in Japan for thousands of years, is made by cooking fermented soybeans. It has a flavour that has been described as akin to fermented cheese. While some love the taste and the sticky-stringy texture, it's often served with condiments such as sliced green onions, wasabi or pickled ginger. Cooking, too, helps make it approachable (Japanese food writer Makiko Itoh, of popular blog JustBento, suggests using it in stir-fries or curries, or in her pan fried natto and potato cakes).
The health perks of natto Natto may not sound that appealing if you aren't a fan of funky flavours, but the growing body of research supporting its health benefits certainly is. Dr Kevin Wang, associate professor of molecular biology ant Northeastern State University, US, is one of the leading researchers exploring nattokinase, an enzyme extracted from natto. “Nattokinase has the ability to get into the blood stream and can directly destroy blood clots, thin the blood and improve blood flow,” he says. “It cleans out the blood vessels, reducing the risk of hypertension and stroke and can also reduce the risk of heart attack.”
According to Wang (who takes nattokinase supplements twice daily), it may well serve as a natural, side-effect free alternative to pharmaceutical anticoagulants such as warfarin. If you’d prefer to try the food version rather than a supplement, you’ll still reap the benefits. “We did an experiment where we found even one natto bean can dissolve fibrin [a protein involved in blood clots],” Wang tells SBS.
Natto Even a small serving of natto may have benefits.
Next generation natto As well as cardiovascular benefits, natto is a rich source of vitamin K2, which is important for bone health. In a 2012 Japanese study, scientists found that habitual intake of natto was associated with significantly higher bone mineral density, which they ascribed largely to the vitamin K content of natto. Other research tracking the bone mineral density change of postmenopausal Japanese women over time discovered that those who consumed natto regularly were less likely to experience bone loss, and as such, may be better protected against osteoporosis.
In the near future we may not even need to cultivate a taste for natto or add yet another supplement to our overly crammed medicine cabinets. “My current research is trying to introduce nattokinase genes into vegetables such as tomato and cucumber, and I’m hoping people will be able to access this in the next three to five years and that the price will be similar to regular fruit and vegetables,” Dr Wang says. “I’ve also been engineering soybeans to produce more nattokinase, so we don’t have to have the fermented ones.”
Fermented foods in the Japanese diet Natto isn’t the only fermented superfood in the Japanese diet. As Anderson discovered during his stay in Japan, the line-up of fermented foods that the Japanese enjoy ranges from pickled vegetables (tsukemono) as a side dish or seasoning, to pickled ginger on top of sushi, umeboshi plums, miso soup and soy sauce, which is made from fermented soy beans. “A traditional Japanese meal includes all these little bowls of things and there’s always a fermented product there,” he recalls. For Anderson, fermented Japanese foods are now a part of his regular diet. “When I make bento boxes to take to work for lunch, I put an umeboshi plum on top of the rice and I’ll often add pickled vegetables to my bowl of rice and natto at breakfast,” he says.
According to Nicole Dynan, accredited practising dietitian and spokesperson for the Dietitians Association of Australia, fermented foods are well worth incorporating. “They are considered probiotics because they contain live bacteria, and there is evidence that they are beneficial in the treatment of diarrhoea, IBS, inflammatory bowel disease and also just for protection against infection generally,” she says. “Fermentation can also increase some of the micronutrients in food, B vitamins particularly, and for some people it can make food more digestible.”
If you’re keen to branch out into Japanese fermented foods, sipping on miso soup, using pickled vegetables as a seasoning or trying natto is a great place to start.
In My Japanese Diet, award-winning actor and comedian Craig Anderson sets out on a dieting experiment towards better health by eating nothing but traditional Japanese cooking for 12 weeks. Watch his journey to Japan, and his new healthy regime, on SBS on April 6 at 8.30, then on SBS On Demand.
Along with natto, which I could not eat, pickled veggies, umiboshi plums, etc are in the good for you category. Friend bought me the Japanese version of pickled veggies, quite a bit tastier than Korean Kim Chee. So tasty, in fact, I was sure it could not be good for me. Kim Chee is supposed to taste awful, isn’t it? Doesn’t the horrid taste make you better right away, just to avoid eating any more of it? Do enjoy Japanese food in a good restaurant, ate it often in San Francisco.
For probiotics, I rely on goat kefir, which I LOVE. Best natural source of probiotics and Vitamin K2, according to online guru Dr. Axe, which you really need to take with D3.
Just ordered nattokinase in capsules from AMZ
Only one judge, said "I actually like natto..." (subtitled).
I just did a bit of research and found that it could be dangerous to supplement with nattokinase if you’re already taking a blood thinner.
Maybe if it were mixed with caramel and bacon...
Is natto the same product as stinky bean curds?
It apparently cleared up a severe calcification problem and I have diagnostic tests as evidence, though the doctors don’t believe it.
Had some yesterday on my rice with dinner . Sometimes I put it on toast .
I thought soybeans were supposed to be bad for you.
There’s a natto restaurant in Honolulu, near Ala Moana Center. The place smells like old dirty tennis shoes.
1. Soba noodles - made of buckwheat

That can’t be true. Soba noodles (yaki soba!) tastes good. Stuff that tastes good can’t be good for you.
Dang it. Now I’m craving an okonomiyaki. An okonomiyaki with Mongolian beef... or Spam. Either one would work.
Dear Lord, no! Natto is Japan’s revenge upon the world. Anyone who would eat that stuff would eat...raw fish or something...
Same with me. I had leg pain from peripherial artery disease for years and shoulder pain due to calcification.
K2 has resolved these problems.
Tried natto in Tokyo from a Chinese street vendor. Once is enough. Don’t know if I want to live forever.
I love Natto! gonna go get myself some more of it!
K2 is available in two forms:
MK4 [Menaquinone-4] and MK7 [Menaquinone-7].
MK-4 can be made to some extent in the body; MK-7 cannot. MK-7 is much more stable and effective than MK-4.
MK-7 is especially rich in Natto, fermented legumes (e.g., soy, chickpea/garbanzo).
Natto is also rich in Nattokinase, a powerful fibrinolytic (fibrin-digesting) enzyme.
The combination promotes beneficial calcium metabolism and cardiovascular functioning.
A supplement of K2 will typically not also contain Nattokinase, and vice versa.
A K2/MK-4 supplement will usually be labelled “K2”; a supplement of K2/MK-7 will usually be labelled “MK-7”. Read the “Supplement Facts” box on the back - regulated by the 1994 DSHEA - for exact and correct description of contents.
It is not a fad in Japan; it is a long-standing part of the reason for their overall superior health.
Asians have known for centuries (if not millennia) that legumes, especially soy, are difficult to digest.
Compared to faddish American vegetarians/vegans, they actually consume less soy, and consume more of it in the highly fermented (pre-digested) forms.
Natto is highly fermented. It also can be made from other legumes, such as chickpeas (although what you would find in a Japanese market would probably be from soy).
