We asked three fermentation experts if recent popularity of fermented foods is a fading trend or a new food movement. These industry professionals weigh in on their predictions for fermentation’s future. The fermenters include Katherine Harmon Courage (author of “Cultured: How Ancient Foods Can Feed Our Microbiome”), Aneta Lundquist (owner of 221 BC Kombucha) and Alex Lewin (author of “Real Food Fermentation” and “Kombucha, Kefir, and Beyond”)
Do you think the surge of fermented food and drinks is a trend will disappear or a new food movement here to stay?
Katherine Harmon Courage, author of “Cultured: How Ancient Foods Can Feed Our Microbiome”: It’s here to stay. I expect to see it expanding and incorporating into more people’s lives. There is really compelling research with the health benefits, but there’s also these amazing flavors for those of us who weren’t raised with it. Like kimchi. Once you eat kimchi, food seems bland and lacking without it. Koreans describe it as “You need kimchi with every meal.” They can’t imagine eating it without. The flavor and texture experience is a big part of eating. We shouldn’t be forcing it down for our health, but truly enjoying it.
Aneta Lundquist, Owner 221 BC Kombucha: The future is fermented. Stretching back as far as human history itself, the origins of fermentation are hard to track down. People have been teaming up with microbes for much longer than we know. Almost every culture appears to have embraced fermentation for millennia but without a deeper understanding of it’s purpose. Fortunately for us, today’s science became “microbes-curios” and surprised us with some terrific findings. One of the most important ones is that we actually are ONE large thriving ecosystem and its survival is based on an ongoing symbiotic dance between microbial and human cells. Those cells communicate with each other and the outside world, exchange their DNAs and they even shape human behaviors. Now, in the 21st Century, we finally started embracing this profound partnership because of its obvious benefits (gut-brain connection, anti-inflammatory properties, digestive help, depression and Alzheimer aid… this list is almost endless). And there is no way back from here. Demand on fermenting foods is going to only grow from now on. As soon as so called “good microbes” from fermented food find a safe home in human guts, they will call for more of its kind. This is how “they” operate! Suddenly, people will crave kombucha, sauerkraut and kimchi-ferment generally. And that is exactly what we are observing now.
Alex Lewin, author of “Real Food Fermentation” and “Kombucha, Kefir, and Beyond”: Fermentation is not a new technology — in fact, it is one of our oldest! People have been doing it for millennia, and microbes have been doing it on their own since before humans even darkened the earth.
So by the numbers, it qualifies as a trend or movement.
But it’s definitely not a fad.
And to be fair, in some parts of the world, fermentation was never “out of fashion”. In Korea, for instance, kimchi has been a staple food for a very long time, often eaten with every meal.
My forecast for North America is that fermentation will continue to grow.
This is because fermentation is the meeting point of a few trends that are on the rise here:
– Health. We are more interested in health (and concerned about health) now than we have been at any time in recent memory. We are learning more about gut health and how it affects the rest of human physiology. Fermented foods are directly related to gut health.
– Food. North Americans watch more food TV than ever before, and celebrity chefs are as famous as pro athletes. People are eating things on a regular basis that their parents had never heard of.
– Sustainability/Infrastructure Resilience. Producing and preserving food without reliance on electricity and other infrastructure is an important thing that we as individuals can do to prepare for an uncertain future that will include climate change and may include dramatic societal change and partial or total infrastructure collapse.
The New York Times asks: are there benefits to drinking kombucha? The article explores hard kombucha and the health claims of drinking the fermented tea. “But for those interested in integrating a variety of microbes into their diet, Dr. Emeran Mayer, author of ‘The Mind-Gut Connection,’ recommends doing so naturally. ‘I personally drink it occasionally,’ he said. Instead of using pills or supplements, he said, alternate different fermented foods, including sauerkraut, kimchi, cultured milk products, and, yes, kombucha.

Raw, clean ingredient pet food is the fastest growing part of the pet food category. More pet food brands are inventing ways to feed their pets unprocessed, organic ingredients. A new article highlights Answer Pet Food, the first (and so far only) fermented raw pet food supplier. Answers Pet Food utilized kombucha, raw cultured whey, cultured raw goat’s milk and kefir in their pet food products. Their products include fermented chicken feet and fermented pig feet. Answers Pet Food says: “Fermentation is the most natural and effective way for us to make our products as safe and healthy as possible. … Our raw fermented pet foods are formulated to create a healthy gut. Fermentation supports healthy immune function by increasing the B-vitamins, digestive enzymes, antioxidants, and lactic acid that fight off harmful bacteria. It’s also the ultimate source of probiotics.”

If just 10% of the population chooses to eat fermented foods, could the food industry be disrupted? Fermentation guru Sally Fallon says: absolutely.
“With fermented foods, you could get rid of all this huge medical industry selling you antacids and digestive aids, and this huge industry that’s grown up around IBS and celiac disease. We can destroy that industry by eating the right foods, and that means eating fermented foods,” Fallon says. The author of cookbook and nutrition guide “Nourishing Traditions” is often credited with bringing ancestral diet methods back into vogue.
Fallon, president of the Weston A. Price Foundation, founder of A Campaign for Real Milk and author of the new book “Nourishing Diets,” discussed fermentation during The Fermentation Summit. Below, selected highlights from Fallon’s interview with Paul Seelhorst, host of the summit.
Seelhorst: Tell us more about yourself and how you got into the fermentation topic.
Fallon: Well, when I was writing “Nourishing Traditions,” I wanted to make sure I was really describing traditional diets and not something people just think they are. I was very fortunate to find a book in French about fermented foods. I had never read about these before, lacto-fermented foods.
Recipes were very complicated – keep them at certain temperature for this many hours, then switch temperature for another few hours.
I kind of took this principle and worked out a way that was easy and fool-proof, using glass jars, we use way of innocuous so they don’t go bad while they’re starting to ferment.
Tried all these recipes, experiments, made children try – kids have funny stories about trying all these
The neat thing about fermentation is that it is a practice that’s traditional. When you ask traditional people why they do this, they wouldn’t know what to say or how to answer you, they just do it. But it totally accords to modern science. We have seen a complete paradigm shift in the last 20 years. In the past, bacteria were evil and they attacked us and made us sick. Now we realize that bacteria are our best friends, and we need at least 6 pounds of bacteria lining our guts in order to be healthy.
The way traditional people made sure that they had plenty of this good bacteria restocking everyday was to eat these raw fermented foods full of this healthy bacteria. They ate them in small amounts with the rest of their meals. This is how they did it, they had really healthy guts. We know when you have a healthy gut, everything goes better in life. You feel better, you digest better, you have more energy.
I recently wrote this book called “Nourishing Diets” which is about diets all over the world and what really struck me was the fermented foods. Every single culture in the world without exception eats fermented foods. Now some of these foods are pretty weird – like fermented seal flippers. Africa is the land of fermented foods. Almost everything they eat in traditional culture is fermented in Africa. They’ll kill an animals and ferment every part of the animal — the blood, the bones, the hoofs, the skin, the organ meats, the fat, the urine. Everything is fermented when they kill an animal.
Seelhorst: That’s pretty easy because its warm?
Fallon: Its warm, the bacteria like it. They have a saying – a rich man needs 10 animals to feed the wedding feast because he feeds everything fresh, but a poor man can feed the same feast with one animals because he ferments everything
Seelhorst: Do you know what they make out of urine, like a probiotic lemonade?
Fallon: I don’t know, they didn’t say. There’s two wonderful books on fermented foods – one is the “Handbook on Indigenous Fermented Foods” by Keith Steinkraus. He was at Cornell and is retired now. I fortunately talked to him while I was working on “Nourishing Traditions” and what he shows, he has a bunch of students from all over the world, especially Africa, and they do studies on the food. For example they take a food like cabbage and they’d measure the Vitamin c and the amino acids then they’d ferment it and measure it again. The vitamins goes way up – some 10-fold increase – and the amino acid increase.”
The other thing fermentation does with grains and meats, it releasees the minerals so they’re easily available.
There’s another wonderful book called “The Indigenous Fermented Foods of the Sudan: A Study in African Food and Nutrition.” The author was a student of Dr. Steinkraus. He reminds me a lot of Weston Price – he’s going to these traditional people not to, you know, lord over them and tell them how superior Western culture is. He goes with hat in hand saying “You guys have the secret here. You know how to eat; you know how to prepare food. Not only that, these foods can be done at the homestead, they can be taken to the market and sold, they are a good income for millions of people.” So he’s not pushing the industrial system, he’s pushing artisan food.” I just thought what a wonderful man, how humble. That’s how we need to come to these traditions – not how to make millions of dollars on them, but how to make a decent living for thousands of people and provide a healthy food for millions of people.”
Seelhorst: What I also like about fermentation is the sustainability aspect. People can make food sustainability and do not need fridges to keep the food good and not get it moldy.
Fallon: Foods like grains are impossible for humans to digest unless they are fermented. So many people can’t do grains, they’re sensitive to gluten. But when you ferment, as in the case of a sourdough bread or soaking your oats or pressed cakes all over the Southeast and Africa, these are fermented grains pressed into biscuits, this takes a food where most of the nutrients are unavailable to us and makes it readily available.
Seelhorst: Nowadays, people have fancy equipment to
ferment food. How did people ferment food back in the day?
Fallon: Usually they did it in large terracotta pots. And the culture was sort of in the holes of the pots, they didn’t have to add a culture, it was just hanging out there. When I started this in the late 1990s, this book I read in French was talking about these big pots. You couldn’t get these pots in the states when I was writing this book. I thought this isn’t going to work, the pots are heavy they’re expensive and they make a very large quantity which you may not be able to use. I thought we need a different method for the modern house wife or modern father. I thought “Let’s try to do this in Mason jars, the big quart jars with the wide top. Instead of having the culture hanging out in the holes, we didn’t have that. You had to add something in your culture, so that’s where we came up with adding whey. You have your cabbage or pickle or carrots or whatever it is you want to ferment, you put them in a bowl, you toss them with salt and a little bit of whey. You toss them, pound them a little bit, push them in the jar, push down heavily so the liquid comes and covers the top, this is an anerobic fermentation. Leave it at room temperature for a few days and its done.
Seelhorst: Where do people get the whey from?
Fallon: We teach people how to make it. You start with yogurt or with raw milk or something fermented like yogurt or kefir and you poor it through a fine cloth and the whey will drip out. From a quart of yogurt, you get about two and a half cups of whey. You’re only using a little bit at a time – a tablespoon or two – so that will keep a long time in the fridge. That’s your culture. There are other cultures, too. People are selling powders in culture. The only thing I would warn you is don’t try to do this without salt. Because the only time I heard about someone getting sick from fermented foods is when they didn’t use salt.
Seelhorst: Simply put – what happens during fermentation.
Fallon: What happens during fermentation is lactic acid is created by the fermentation. And in some foods, the lactic acid is already there. Like cabbage, cabbage juice is full of lactic acid. This makes whatever you’re fermenting get sour, it lowers the pH to under 4 and no pathogens can exist at a pH under 4. It makes the foods very safe and they don’t spoil after that. Lactic acid is a preservative just like alcohol is a preservative, but lactic acid doesn’t make you drunk. So, at the same time, these bacteria that are fermenting in there, they’re creating vitamins. Vitamin C, b vitamins. They’re breaking down what we call anti nutrients that block the simulation of minerals. They’re creating digestive enzymes that help you digest your food. The interesting thing is these bacteria and these enzymes do get through the stomach, they do get through and are passed into the small intestines where they are really useful. We’re not sure how that happens, they’re buffered in some way, but we do know these bacteria do get through
Seelhorst: How do you think fermented foods can fit into a modern diet.
Fallon: You can include them every day. One of my favorites foods is a fermented beet juice, I first noticed it in Germany, it’s called beet kvass. I have that every morning for breakfast. Sauerkraut is a really easy way, that’s the way most people do it, they just have sauerkraut with their meal. And then the fermented dairy foods like yogurt or kefir, those are wonderful fermented foods. You have a little bit with every meal.
Seelhorst: Are those the oldest fermented foods that we ate?
Fallon: In Europe, yes. We don’t have a tradition of eating fermented bones or fermented blood. But we definitely had fermented vegetables like sauerkraut, that dates to Roman times at least. And also fermented fish, the fish sauce, the universal seasoning, they found it in the ruins of Pompei where they were making it.
Seelhorst: What’s the difference between industrialized and self-made fermented food.
Fallon: once you industrialize something, they start to take shortcuts because they want to lower the cost. Typically, what they’ll do is eat something. So they’ll heat the sauerkraut and package it in plastic bags or something horrible or they’ll can it. So it will last forever and be shelf stable. Typically, the industry has not done genuine fermented foods because its not something that lends itself to an industrialized process. The things we consider true fermented foods in the united states, they’re being made by small companies.
Now the one exception to that might be yogurt. Yogurt is big business, it’s made by the big conglomerates. I would never even eat that yogurt because apparently the cultures are not even any good and the milk has been pasteurized.
Seelhorst: What’s your favorite fermented food.
Fallon: Kombucha. I make my own kombucha. I have a 30-day kombucha, I call it kombucha like fine champagne. It gets these tiny, tiny bubbles in it, it gets really, really sour and a little thick. I also make sauerkraut. It’s interesting – I’m a lot busier than I was when I wrote my book, I don’t have as much time as I used to have, but I still make my own fermented food. I do carrots and cabbage, I’m just about to pull some carrots and make some fermented cabbage.
I forgot to mention cheese. And cheese. Cheese is a fermented food. Here on our farm, we make cheese. I’d have to say cheese is my favorite fermented food. And also, traditionally made salami. A charcuterie is fermented. They hung these sausages up and fermented them. So they are fermented foods, they’re full of bacteria, good bacteria. They should be kind of sour, they’re very good for you.
Seelhorst: Do you want to add anything for people that just found the Fermentation Summit and may not know what fermentation is, they want to try it
Fallon: I will say this – you don’t have to make it yourself, there’s a lot available, in the states there’s now hundreds of artisan producers making sauerkraut. I love to see that – I love to seen an individual be able to start a little business without a big capital investment and make food that’s really good for people and make a decent living. Here on our farm, we have a store and we sell sauerkraut made by a Russian lady who has just made a wonderful living doing this. I love to see that. Just like artisan cheese. I love see small production of cheese; I love small production of fermented goods. Bread is another one, we now have a lot of artisan bread makers. This is the future of food – its sustainable food, its moral food, its food that makes you healthy, its good for the economy, it keeps the money in your community. I think people need to realize that every morsel of food they put in their mouth is a political act. It’s a decision they make. What are you going to support? Are you going to support Monsanto and Kraft and Unilever? These huge corporations who don’t care about you at all, all they care about is making a profit. Or are you going to support local artisan producers? People just like you making a decent living and providing a healthy food. And you’re also deciding whether you’re going to put something healthy or unhealthy in your body and in your children’s bodies. The traditional cultures, they had no choices in what they ate. They ate what was there, they ate according to their traditions. Today, we are not traditional people. We have left all that behind. We have to think what we eat, everything we eat is a choice. They didn’t have a choice, they just had healthy food. Now we always have this choice between healthy artisan food and unhealthy corporate food. So what kind of society do you want to live in?
Ever wonder why you crave umami, the savory food taste common in fermented foods? You were born with it.
“When you say taste, it’s actually just as much the nose because were actually using all the five senses when we say taste or taste experience,” says Ole Mouritsen, a professor of gastrophysics at Copenhagen University in Denmark. “Taste and particularly odor is very good to invoke memories, good memories and bad memories, because that’s the way its hardwired in the brain. These senders that store our memories are stored to the limbic center, and the processing center for taste and odor are in the same area. You can be brought back to your grandma’s kitchen in no time.”
The five basic tastes are: sweet, sour, salty, bitter and savory (umami).
He continues: “There are some basic tastes and odors that you prefer. We’re born to like sweet and umami, and we’re born to dislike bitterness and too much sourness. But our preferences change over time.”
Mouritsen and Adam James, founder of fermentation condiments company Rough Rice, spoke with Cooking with Science host Kevin Glidden on the topic of fermentation and taste. Glidden brings researchers and foodies together in an interactive interview for the Tasmanian Institute of Agriculture.
Glidden asked why Mouritsen and James think fermented foods played such a big part in other culture’s diets, but not in the Western diet.
James travelled on a Churchill Fellowship-backed fermentation world tour to study ancient and modern fermentation techniques. He pointed out that fermentation has never been part of Western culture.
“If you look at what my biggest influences are – Japan, Korea, China – they eat fermented foods pretty much with every meal, in the form of a pickle or a soy sauce,” James said. “But again, I think that’s something that’s just been part of their culture. Families would sit down and make kimchi together.”
Mouritsen agreed, adding: “If we want to learn about making old-fashioned pickles, we will not ask our mothers, we’ll ask our grandmothers, because the knowledge is lost.”
In the segment, James made a brown rice congee with Tasmanian abalone and fermented condiments. Congee – an Asian rice porridge – dates back 4,700 years, 1,000 years before shoes were invented. James’ cooked his congee using untraditional methods. Congee is usually made using a chicken stock or duck stock as a base, but James made his congee with shitake mushrooms, fresh tomatoes and kelp. Though no meat was used, the result was an umami-tasting flavor.
A new Kerry Health and Nutrition Institute white paper titled “Umami: The Taste that Perplexes” details why umami is a vital food flavor. Umami’s functions and biological mechanisms are not very well understood. “…Unfortunately the way many people have learned about umami is through the stigma of monosodium glutamate (MSG), the prototypical stimulus of umami taste,” writes author Nancy Rawson, the associate director of the Monell Chemical Senses Center.
The umami flavor, though, extends well beyond MSG. It can be found in every day food, like mushrooms, tomatoes and aged cheese. Umami is popular in Asian cultures, where fermented food is high in the glutamate compound. Fermented fish and fish sauce are a common cooking item in South East Asia cuisine, creating “a more balanced taste.” Miso and soy bean paste are used in North Asia, where they flavor food with “a natural and longer lingering taste and mouthfeel.”
Mouritsen said umami is one of the ultimate dining experiences. He adds: “It gives you appetite, when you stick it in your mouth, the saliva starts running. It’s a very good way of getting appetite. We have receptors in the stomach, in the intestinal system, that signals back to the brain that those umami-rich food, and it will eventually tell you to stop. It’s knowledge one could use to make more healthy eating patterns for people.”
Western North Carolina is becoming “a hot spot for fermented goods” thanks to female entrepreneurs. These fermented product brand leaders credit the health-conscious culture of Asheville, N.C. with helping their businesses thrive in “Ferment City.” Sara Schomber of the Buchi Mamas tells Asheville’s Mountain Xpress: “Fermentation is all about the alchemy of ingredients normally found in the hearth and home where, for centuries, women have been the keepers. We believe fermentation is the expression of a natural tendency, the human spirit’s way of giving itself permission to heal and inviting all of us to extend beyond our own immediate mortality. It’s normal and natural for humans to want to preserve, put away and celebrate.” Local brands featured include: Shanti Elixirs Jun, Smiling Hara Tempeh, Yoga Bucha kombucha, Buchi Kombucha, Sister of Mother Earth cider and honey, Serotonin ferments ferments and Fermenti Foods ferments.

Good news for fermented food and drink brands. Today’s increasingly disruptive, consumer-driven economy is favoring brands that are craft and artisanal, source responsibly, reduce waste, nourish their microbiome and aim for better treatment of the planet. These are already core operating values for many fermentation brands.
“Consumer values are shifting in the marketplace; businesses are working hard to find ways to use their business as a force of good. Consumers are increasingly engaged in supporting the businesses that are looking to disrupt the status quo, that are looking to change,” said Eric Pierce, vice president of strategy and insights for New Hope Network. “Our market is moving in this direction with more innovation, with more access, with more options for consumers that are easier for them to get a hold of…we will find more and more people opting into the products we are bringing to the marketplace.”
The top trends driving the natural products industry were shared at a “What’s Next” session for industry leaders at Expo East. Here are six trends the fermentation industry can use to grow their company.
1. Brands Supporting the Planet
From the treatment of animals on the farm, the soil used to grow the vegetables and the type of packaging used, the environment is on the top of consumer’s minds. Consumers want to support brands that practice regenerative farming, zero waste production and responsible supply chain sourcing.
“The top three trends fell under purpose-driven commerce,” said Amanda Hart, market research manager for NEXT Data & Insights. She said consumers want brands to be more mindful, proactive and “really dive in and solve for community health and issues where government regulation is lagging or lacking.”
2. Selling Outside the Health Food Crowd
Since the start of the natural food industry, natural and organic foods were mostly purchased by a demographic of shoppers SPINS market research defines as “Core Natural/Organic.” These “true believers” and “enlightened environmentalists” make up the majority of natural industry shoppers.
Meanwhile, the mainstream consumer has traditionally been a harder group for brands to reach. These “indifferent traditionalists,” “struggling switchers” and “resistant non-believers” make up the smallest part of natural product sales.
That gap is closing – today 92 percent of all households buy organic products, and 99 percent buy natural products.
Pierce noted he was surprised when studying these groups that the reason they purchase natural products is now the same.
“What this means to us is their level of commitments to products in the industry, their level of commitment to brands is dramatically different,” Pierce said. “But consumers across our economy value similar things what it comes to what they’re looking for from us.”
“Increasingly, these products are resonating with mass retailers,” he continued.
The findings also showed the food trends that resonate with consumers were not influenced by their political leaning. Whether Democrat or Republican, consumers care about the same food values.
The top five food trends these groups care about: waste reduction, responsible sourcing, responsible meat and dairy, craft and artisanal and responsible packaging.
3. Expanding Knowledge of Microbiome
Probiotics – which has topped SPINS trend lists for years — is no longer claiming a top spot. This doesn’t mean consumers don’t care about gut health, though. Consumers are looking at different beneficial options for their microbiome.
“How can consumers cultivate a health microbiome, to make us our strongest selves as we navigate the forces of modern life?” Hart said.
There is lots of research on nourishing a healthy microbiome. Brands should market gut health to consumers, especially with scientifically-backed claims on how fermented foods aid the gut bacteria.
4. No Added Sugar
Sugar – especially added sugar – has long been the nemesis of natural food shoppers. But consumers now want blatant communication from brands on product flavoring.
“Sugar and sweetener are different, so some brands now are starting to leverage both of those terms and really communicate how they’re adding a sweet flavor to their product – or not adding,” Hart said.
Botanical flavoring is starting to become a sweetner alternative for brands.
5. Alcohol-Free Drinks
Concerned with their health and focused on mindful drinking, Americans are purchasing less alcohol. Data from industry tracker IWSR found that U.S. alcohol volumes are dropping every year. Beer was the lowest, with volumes down 1.5 percent in 2018 and 1.1 percent decline in 2017. Growth in wine and spirits also slowed. This is especially true among younger, millenial consumers.
The taste for a fermented craft beer or cocktail is not waning, though.
This trend was seen on the show floor, where more and more alcohol-free brands are marketing alcohol-free drinks, like non-alcoholic beers, sugar-free mocktails and sparkling vinegars.
6. DIY Rules
Consumers want to be part of the creative process, “like they’re building products for themselves,” Hart said. Pierce added: “consumers value innovation efforts…that engage their sense of adventure and exploration.”
Fermentation brands are catering to consumers DIY nature by offering recipes to experiment with their product, like kefir smoothies, kombucha cocktails or sauerkraut omelets. Some fermentation brands are even selling fermentation kits for home use.
More fermentation brands are creating ways to connect with their customers, face-to-face. Harvest Roots Ferments started in 2012 as a small farm in Birmingham, Ala. “At the time, Lindsay was fermenting kraut and kombucha for our farmers market table. Our customers wanted ferments way more than kale,” said Pete Halupka, who runs Harvest Roots Ferments with Lindsay Whiteaker. “About three of four years ago, we committed fully to fermentation. Now we produce kombucha, kraut, kimchi and other fermented vegetables and sell them across Alabama.” Now Harvest Roots Ferments is opening Birmingham’s first kombucha taproom. No longer traditional farmers (they source from local farmers, buying 75,000 pounds of produce since 2015), Harvest Roots Ferments is looking to build and connect to the Birmingham community that has helped their business grow. Halupka continues: “We love community in all forms—from the microbial community in action fermenting our products to the community found in our Southern forests and our human community across Birmingham—and we want our space to be a reflection of this.”

Summer Bock compares the gut microbiome to a forest. If a fire destroys the forest and forest restoration is attempted by just introducing a few animals, the forest would never rebuild.
“That’s what we’re missing with probiotic pills,” Bock says, adding that relying on a probiotic pill to fix the gut is like telling a few bacteria strains: “’You’re in charge of building our entire gut microbiome,’ you just can’t. if you’re just picking a few probiotics and saying ‘You’re the work horse, you’re going to do all of it,’ they can’t. You have to go think of this bigger picture ecosystem. When we use ferments, we’re bringing in some of the nutrition, the soil and even bringing in a greater variety of probiotics than what you find in most pills. …there’s a huge benefit of ferments that people are missing out on.”
A fermentationist, health coach and founder of Guts and Glory, Bock detailed how fermented foods can improve overall health at the Fairmentation Summit. She coined the word “gut rebuilding” and was the founder of the Fermentationist Certification Program.
Bock started fermenting after becoming incredibly sick. A trained herbalist, Bock began treating multiple food allergies, regular panic attacks and chronic exhaustion with herbs. This was long before terms like probiotics and gut microbiome were a regular part of diet discussions. But Bock was recommended by a naturopathic doctor to try taking probiotics, and “a lot of my symptoms started clearing up very quickly.”
Bock, though, is a purest, and wanted to know how she could ingest probiotics without taking a pill.
“What’s the whole food version of probiotics?” Bock said. “If I’m missing it and I’ve wiped it out with antibiotics, how did my ancestors get this into their body on a daily basis? That’s how I discovered fermented foods.”
So Bock started fermenting everything. During this experimentation process, Bock sold sauerkraut and kimchi from her fridge, launching her first sauerkraut company. She described sharing sauerkraut with her roommate’s friends, skeptics who would initially say “I don’t like it,” but would come back a week later and tell her “I have to come back and but it because I can’t stop thinking about that one bite.”
“This is an addictive healthy food, and I got fascinated by what is happening on your taste buds that makes your body go ‘I don’t like this right now,’ but your body recognizes that health benefit,” Bock said. “If there’s some communication happening through one little bite of food and that person can’t stop thinking about it and they want it, I’m still utterly fascinated by that today.”
Her favorite fermented food is kimchi “because it has all the benefits of lacto-fermented vegetables, it has all the great probiotics in it plus it has prebiotics, it has organic acids and the lactic acid which is a natural microbial.”
Studies during the avian flu outbreak found birds who ate kimchi were not contracting the bird flu. One microbiologist in South Korea found 11 of 13 chickens infected with avian flu who ate kimchi made a full recovery. All birds in the control group died.
“Fermented foods are really powerful, and I think that what’s fascinating about them for me is they differ from just probiotics. They contain probiotics, but they also have the prebiotics. They have the entire ecosystem,” she said. “We eat it because it’s delicious, but we also eat it because that food assists us in some way.”
Probiotic-rich ferments “acts as a fertilizer” for the gut microbiome, killing off pathogenic organisms. Microbes grow best at room temperature, a temperature the health department defines as a danger zone because it’s the best temperature for pathogenic, food-born illness to grow.
“What we’ve found is, when there’s that acidic environment, these pathogenic food-borne illnesses can’t exist there. They don’t grow,” she adds.
Multiple nutrients are produced through fermentation, like Vitamin B and Vitamin K. Only a few organisms produce these vitamins, Bock notes. They are critical vitamins because they’re not absorbed easily through food. Bok calls them the “star players” of the microbiome. People with an imbalanced microbiome are often lacking in vitamins B and K.
If not fermenting their own food at home, consumers need to practice due diligence when purchasing fermented food brands, Bock says. Kombucha, she shares as an example, is a great “gateway ferment” for most people, but how much sugar is in it? Is it fermented naturally or are lab strains of probiotics added?
“You have to ask yourself, what is the major probiotic we’re talking about,” in the food you’re eating, Bock said. “Is it a naturally-occurring probiotic or a…patented, genetically-modified probiotic?”
Americans have a “Supersize” mentality, Bock said. People shouldn’t be consuming bowls of fermented foods every day.
“Remember that fermented foods are generally a condiment, especially the ones with live organisms, like kimchi and sauerkraut, natto,” she said. “So if you treat it as such, you’re maintaining the respect for these organisms and for these foods,” she said. “Your body knows what it needs.”
Farmhouse Culture is retooling their packaging, moving away from what the CEO calls “natural food cliches.” Using consumer research as their guide, the fermentation brand is using “always organic” on their labels, indicating quality to shoppers. Farmhouse Culture is also decreasing their emphasis on probiotics because, though shoppers want products with digestive health benefits, they’re confused over how to achieve digestive health. The Wisconsin-based brand makes sauerkraut, fermented veggie drinks and sauerkraut chips.
