Nutrition professionals need to share the details when recommending fermented products to clients. What are the health benefits of the specific food or beverage ? Does the product contain probiotics? Live microbes?

“There are a vast array of fermented foods. This is important because it means there can be tasty, culturally appropriate options for everyone,” says Hannah Holscher, PhD and registered dietitian (RD). But, she adds, remember that these are complex products.

Holscher spoke at a webinar produced by the International Scientific Association for Probiotics and Prebiotics (ISAPP) and Today’s Dietitian. Joined by Jennifer Burton, RD and licensed dietitian/nutritionist (LDN), the two addressed the topic Fermented Foods and Health — Does Today’s Science Support Yesterday’s Tradition? Hosted by Mary Ellen Sanders, executive director of ISAPP, the presentation touched on the foundational elements of fermented foods, their differences from probiotics, the role of microbes in fermentation, current scientific evidence supporting health claims and how to help clients incorporate fermented foods in their diets. 

Sanders called fermented foods “one of today’s hottest food categories.” Today’s Dietitian surveys show they are a top interest to dietitians, as the general public often turns to them with questions about fermented foods and digestive health. 

Here are three factors highlighted in the webinar that dietitians should consider before recommending fermented foods and beverages.

Does It Contain Live Microbes?

Fermentation is a metabolic process – microorganisms convert food components into other substances. 

In the past decade, scientists have applied genomic sequencing to the microbial communities in fermented foods. They’ve found there’s not just one microbe involved in fermentation, Holscher explained,  there may be many. The most common microbes in fermented foods are streptococcus, lactobacillaceae, lactococcus and saccharomyces.

But deciphering which fermented food or beverages contains live microbes can be difficult.

Live microorganisms are present in foods like yogurt, miso, fermented vegetables and many kombuchas. But they are absent in foods that were fermented then heat-treated through baking and pasteurization (like bread, soy sauce, most vinegars and some kombucha). They’re also absent in fermented products that are filtered (most wine and beers) or roasted (coffee and cacao). And there are foods that are mistakenly considered fermented but are not, like chemically-leavened bread, vegetables pickled in vinegar and non-fermented cured meats and fish.

“The main take-home message is that it’s not always easy to tell if a food is a fermented food or not. So you may need to do more digging, either by reading the label more carefully or potentially contacting the food manufacturer,” Holscher said. “When we just think of if live microbes are present or not, a good rule of thumb is if that food is on the shelf at your grocery store, it’s very likely that it does not contain live microbes.”

Does It Contain Probiotics?

The dietitians stressed: probiotics are not the same as fermented foods.

“Probiotics are researched as to the strains and the dosages to be able to connect consumption of a probiotic to a health outcome,” Holscher said. “These strains are taxonomically defined, they’ve been sequenced, we know what these microorganisms can do. They also have to be provided in doses of adequate amounts of the live microbes so foods and supplements are sources of probiotics.”

Though fermented foods can be a source of probiotics, Holscher notes: “In most fermented foods, we don’t know the strain level designation.”

“For most of the microbes in fermented foods, we’ve just really been doing the genomic sequencing of those over the last 10 years and so we may only know them to the genus level right,” she said. For example, we know lactic acid bacteria are present in kimchi and sauerkraut.

Holscher suggests, if a client has a specific health need, a probiotic strain should be recommended based on its evidence-based benefits. For example, the probiotic strain saccharomyces boulardii is known to help prevent travel-related diarrhea, and so would be good for a patient to take before a trip.

“If you’re looking to support health and just in general, fermented foods are a great way to go,” Holscher says.

The speakers recommended looking for probiotic foods in the Functional Food Section of the U.S. Probiotic Guide.

Does Research Support Health Claims?

Fermentation contributes to the functional and nutritional characteristics of foods and beverages. Fermented foods can: inhibit pathogens and food spoilage microbes, improve digestibility, increase vitamins and bioactives in food, remove or reduce toxic substances or anti-nutrients in food and have health benefits.

But research into fermented foods has been minimal, mostly limited to fermented dairy. Dietitians should be careful making strong recommendations based on health claims unless those claims are supported by research. And food labels should always be scrutinized.

“There’s a lot of voices out there that are trying to answer this question [Are fermented foods good for us?],” says Burton. “Many food manufacturers have published health claims on their labels talking about these benefits and, while those claims are regulated, they’re not always enforced. Just because it has a food health claim on it, that claim may not be evidence-based. There’s a lot of anecdotal accounts of benefits coming from eating fermented foods and the research is suggesting some exciting potential mechanisms. But overall we know as dietitians we have an ethical responsibility to practice on the basis of sound evidence and to not make strong recommendations if those are not yet supported by research.”

Reputable health claims are documented in randomized control trials. But only “possible benefits” can be linked to nonrandomized controlled trials. And non-controlled trials are  the least conclusive studies of all.

For example, Burton puts miso in the “possible benefits” category because, with its high sodium content, there’s not enough research indicating it’s safe for patients with heart disease. Similarly, she does not recommend kombucha because of its extremely limited clinical research and evidence. 

“We have to use caution in making these recommendations,” Burton says.

This is why Burton advises dietitians to be as specific as possible. Don’t just tell patients “eat fermented foods” — list the type of fermented food and its brand name. She also says to give patients the “why” — what is the benefit of this fermented food? Does it increase fiber or boost bioavailability of nutrients? 

“Are fermented foods good for us? It’s safe to say yes,” Burton says. “There’s a lot that we don’t know, but the body of evidence suggests that fermentation can improve the beneficial properties of a food.”

Fermented Dairy Improves Memory

A new study found fermented dairy products reduce memory loss. The study, published in Nutritional Neurosciences, confirms there is a connection between the gut microbiome and the nervous system, known as the gut-brain axis 

The adults in the test regularly consumed a dairy-based fermented drink, containing 25-30 billion colony forming units (CFUs). Drinking fermented dairy — like yogurt, kefir or fermented whey — “increased the presence of certain microorganisms in the gut and improved relational memory in healthy adults.”

Yogurt Alters Gut Microbiome

It’s widely appreciated that consuming high-quality yogurt can aid a healthy diet. Now new research shows eating yogurt changes the composition of the human gut microbiome.

In a new human study published in BMC Microbiology, researchers studied the microbiome of European twins. Results found those regularly eating yogurt had less visceral fat mass, reduced insulin levels and an increase of bacterial species in the gut. Strains S. thermophilus, B. animalis subsp. lactis., S. thermophilus and B. animalis subsp. lactis were all present in yogurt eaters.
The study also found the yogurt bacteria are “transient members of the gut microbiome and do not durably engraft within the gut lumen.”

Miso, frozen yogurt and pickled and fermented vegetables are driving growth in the $10.97 billion fermented food and beverage category. The fermented products space grew 3.3% in 2021, outpacing the 2.1% growth achieved by natural products overall.

“It really highlights how functional products have become the norm for shoppers when they’re in stores,” says Brittany Moore, Data Product Manager for Product Intelligence at SPINS LLC, a data provider for natural, organic and specialty products. Moore notes there’s an “explosion of functional products” in the market — “[they] are appearing everywhere. And fermented products have been leading that space in the natural market for years.”

The data was shared during TFA’s conference, FERMENTATION 2021. SPINS worked with TFA to drill into data covering 10 fermented product categories and 64 product types (an increase from last year). [A note that wine, beer and cheese sales are excluded from the data. These categories are very large, and would obscure  trends in smaller segments. Wine, beer and cheese are also well-represented by other organizations.]

Yogurt dominates the fermented food and beverage landscape with 75% of the market, but sales growth is soft. Frozen yogurt and plant-based offerings, though small portions of the yogurt category, are fueling what growth there is. “Novelty products are catching shopper’s eyes,” Moore notes.

 Kombucha, the fermented tea which led the U.S. retail revival of fermented products, still rules the non-alcoholic fermented beverages market, with 86% of sales. But growth is slowing. Moore points out that this slowdown is due to kombucha having penetrated the mass market with lots of brands on grocery shelves.

“There’s opportunity in kombucha for new innovations to catch the progressive shopper’s eye,” Moore says. “Shoppers are looking for an innovative twist to their functional product.”

Moore points to successful twists like hard kombucha, which grew nearly 60%, and probiotic sodas, which grew 31%.

Growth is slowing for hard cider, too, though hard cider leads the alcoholic beverages category with 83% share of sales. 

All sectors of the pickled and fermented vegetables category are growing, totalling nearly $563 million in sales. Refrigerated products are nine of the top 10 subcategories here. The “other” pickled vegetable subcategory is increasing at a 60% growth rate, “other” being the catch-all  for vegetables that are not cucumbers, cabbage, carrots, tomatoes, beets or ginger. Fermented radish, garlic and seaweed fall into this subcategory.

Soy sauce is not surprisingly still the largest product in sauces, representing 58% of the category. But that share is dropping. Gochujang is the growth leader, increasing at rate of nearly 20%.

Miso and tempeh are also performing well, which Moore attributes to the growing plant-based movement and the Covid-19 pandemic pantry stocking boom. Miso products — soups, broths, pastes and mixes — totaled over $24 million in sales in 2021. Though instant soups and meal cups represented only 8% of sales, they grew more than 110%.

For the fifth year in a row, fermented foods again top the Today’s Dietitian annual list of superfoods.

The 10th annual What’s Trending in Nutrition survey “reveals a wave of change resulting from the pandemic.” Public relations firm Pollock Communications, who conducted the survey for the magazine, surveyed 1,173 Registered Dietitian Nutritionists (RDNs) about trends for 2022. The “most surprising change from the past decade,” RDNs agreed, was “the shift from low-carb to high-fat diets…followed by plant-based eating.” 

Health- and immunity-boosting food “will be the biggest trend in the next decade that will shape changes in the food industry.” Immunity support, affordability and emotional well-being are consumers’ top purchase drivers; convenience, healthy, taste, low-cost and natural are the top label attributes.

The label attribute “healthy” first made the top three list in 2019 “as consumers began to better understand the connection between food and overall well-being.” RDNs say the Covid-19 pandemic accelerated the healthy food trend.

“With the focus on health and immunity in the next decade, and the increased popularity of plant-based eating, nutrient-dense options will be an important part of consumer diets, as [consumers]embrace food as medicine to help prevent disease,” says Louise Pollock, president of Pollock Communications. “In addition, there will likely be an increased interest in functional foods containing ingredients that provide health benefits beyond their nutrient profile.”

Consumer desire for gut-boosting benefits pushed fermented foods to #1 on the list. Changes to the top 10  show salmon is out and ancient giants are in. 

“The predictions of RDNs, the frontline experts in food and nutrition, are always reliable to help food and beverage manufacturers and marketers meet the demands of consumers. Our survey has accurately tracked health and wellness trends for a decade,” says Mara Honicker, publisher of Today’s Dietitian. “We are pleased to have been able to share these insights for the past ten years and especially during this chaotic time in our lives, when food is playing such a major role in providing health, wellness and emotional support.”

The full superfoods list is:

  1. Fermented foods, like yogurt and kefir
  2. Blueberries
  3. Seeds, like chia and hemp
  4. Exotic fruit, like acai and golden berries
  5. Avocados
  6. Green tea
  7. Nuts
  8. Ancient grains
  9. Leafy greens, like spinach
  10. Kale

Sebastian Vargo was an up-and-coming chef on the Chicago food scene when the Covid-19 pandemic hit and shuttered restaurants. Laid off from his job as head chef at Merchant Restaurant, Vargo experimented with different gigs — yoga teacher, realtor, even t-shirt graphic designer — but kept coming back to his passion: creating food.

So Vargo and his fiancée, Taylor Hanna, launched Vargo Brother Ferments. They produce a creative line-up of fermented condiments, sauces and beverages, including items like a pickled garlic sauce, chipotle beet sauerkraut, Mighty Vine tomato vinegar, Concord grape kombucha and a Bulgarian yogurt with fermented strawberry jam and miso peanut butter. 

“Ultimately, I’m a flavor chaser,” Vargo says. “Fermentation is not really an obligation, it’s a necessity to really unlock certain flavors.”

Most of what they make is  seasonal, created from fresh ingredients sourced locally from Chicago community gardens or out of Vargo’s backyard garden. Flavors heralding back to Vargo’s childhood are also featured. Collard greens kimchi is one example, featuring the leafy vegetable frequently served at  Vargo’s family dinner table as he grew up in Detroit. 

“You can’t help but find a little bit of nostalgia in what you make. Flavors are so connected to memories,” Vargo says. He recalls his mother’s buttery cornbread, her pinto beans flavored with a smoked ham hock and his grandmother’s braised short ribs with sauerkraut. “We were this African-American family in the Midwest in the ‘90s with Southern heritage, so some of my food preserves some of that history. With fermentation, there’s an intersection of both physical preservation and historical preservation. My fermented vegetables are an homage to the past, presenting certain vegetables in interesting and complex ways.”

Vargo and Hanna currently run their business from their home kitchen, selling over Instagram, at farmers markets and through collaborations with local restaurants around the Chicago area. They’re nearing the end of a Go Fund Me campaign to help move Vargo Brother Ferments into a commercial kitchen and, eventually, a storefront. . 

Below is an edited Q&A between Vargo and The Fermentation Association.

The Fermentation Association: How did you first get into cooking?

Sebastian Vargo: My origin is with my grandmother. My mom worked really hard, she worked nights and then she was going to school as well. My grandmother was in our household a lot, she taught me and my brothers [the namesake behind Vargo Brother Ferments] a lot of life skills, how to box, how to play basketball, how to cook. I have fond memories of eating sauerkraut as a child out of a coffee mug with a fork. She was my earliest inspiration, I have fond memories of my grandma in the kitchen.

TFA: And how did you get into fermentation?

SV: My grandma introduced me to sauerkraut. It was such an exciting flavor, I hadn’t experienced the brininess of lactic fermentation, the way it feels on my tongue and cheeks. My mom loved to take us to local delis and we loved Reuben sandwiches. We’d go to a lot of Jewish delis in southeast Michigan, and they had salt brine pickles. That was a real fermented pickle, that flavor is something, too, that really kind of jump started my interest in fermentation.

And then, just working with cool chefs. A new part of my mind was unlocked at every restaurant. Great chefs helped cultivate my love of fermentation. Being in the industry in Chicago is so cool. Every last one of us, we’re all trying to experiment and see what we can do with flavors. When I worked for Stephanie Izard at Girl & the Goat, we were doing kimchi for certain dishes. At Schwa with Brian Fisher and later Wilson Bauer, we made our own yogurt and fermented our leeks, our apricots. And then when I worked for Tony Quartaro at Dixie, he was really pushing the envelope with this Southern-style restaurant where we took inspiration from around the world in a way and applied it to this Southern technique. We had some peaches come in that were underripe, we couldn’t use them for the actual dish, so instead he mixed it with some rum and taught me how to make a vinegar out of it.

TFA: What took you from Detroit to cheffing in Chicago?

SV: It was one Le Cordon Bleu commercial. I was young, I was in a bit of a crossroads and I made the decision to go to the Le Cordon Bleu culinary school in Chicago. I was working at the Salvation Army at the time and I got on the Megabus with my little thrift bags and maybe $800. I had no plans, I found out $800 will not get you an apartment in Chicago, so I stayed in hostels. Before I got enough money for culinary school, I worked as a canvasser to make money. 

TFA: March 2020. You are the head chef at Logan Square’s Merchant and your fiancée was cooking at the Ace Hotel. Then Covid-19 lockdowns happen. Tell me how your lives changed.

SV: Merchant was the first restaurant where I was head chef, it was fun. We made our own hot sauces, we fermented pickles. But once I had the call that we were closing for Covid, I was ready to figure something out. I was a little bit burnt out from the industry at the time. I  was ready to leave, it’d been a lot of pressure and a lot of stress for a while. So, like a lot of Americans,  we took the unemployment. I had never been on unemployment. Being unemployed gave me a chance to finally reset. I was working up to 120 hours a week cheffing around. Now I could see what else is out there.

The whole time I was looking outside of the industry, me and Taylor were still doing  a lot of experiments in the kitchen. We  were making a lot of bagels, making pickles. I have a friend Joe Morski who runs a one-man sandwich operation called Have a Good Sandwich. It’s like a rotating sandwich club in Chicago. Meanwhile, I was trying to start a pickle club, and I asked him if he wanted to serve my pickles in the lunch pack for his sandwiches. That was my first foray into getting my pickles out there. From there, we just started peddling our jars.

TFA: What was the transition to your own business?

SV: To this day, there’s so few fermented, unpasteurized pickles on the market. It wasn’t even a search for a niche, it was something I love to do and I was excited to share my flavor palette with the public. Fermentation is a fun way to be creative, to use it as a platform for new dishes, to play aground with colors. It’s definitely been a great medium to pursue my love of food, of art. Feeding people is my love language. And fermentation is definitely something that’s going to live on forever. It’s wellness, it’s never going to go out of style.

TFA: Tell me about your G-Dilla pickle. That’s a customer favorite. What makes it so special?

SV: The G-Dilla pickle is a flagship that’s always in season. The name G-Dilla, we have blank labels and I didn’t want to write “Garlic Dill” each time. So I started G-Dilla as an homage to J-Dilla, a great producer [and rapper from Detroit].

The taste is akin to a Jewish deli, a garlic dill pickle, the one that would accompany a Reuben sandwich. I just take it kind of a step further with the herbs and the garlic. We use black tea in our pickle brine, it is a fun way to add tannins to the mix which provides that nice, crunchy skin. We really enforce the flavors through fresh herbs, fresh dill from our backyard, parsley, grape leaves, fresh bay leaf and we add lots of garlic and toasted block peppercorn and mustard seed. Maybe a little gochujang, some turmeric. You bite into one and you’re getting that loud crunch and you’re just getting that lactic acid zing that’s electrifying the flavor. It makes you stop what you’re doing, you can’t talk through it, you have to finish chewing and enjoy the whole experience. It’s been a journey — I think back to the first pickle I made to now and it’s something I’ve kept at, I’m a student of the game, always striving to learn more techniques and refine what I’m doing.

TFA: Why do you think more and more chefs are exploring fermentation?

SV: I think so many chefs are seeing the flavor benefits alone. Food fermentation offers a more nuanced flavor that you just can’t achieve the same way. Fermentation is in everything that we do, everything that we eat. There is really an endless source of inspiration and flavor for chefs. We’ve seen the interest pick up in fermentation, but it’s not a fad in the food world. Fermentation is something that is here to stay, with the recent explosion and interest in it, fermentation will find a nice settling place in food. 

TFA: What do you think is the future of fermentation?

SV: I would like to see a future in which fermentation is no longer just a trending topic, something that everyone acknowledges for its real health benefits. So people aren’t just taking a probiotic gummy, they know they can get probiotics easily through so many foods. Society is at a place where we are not quite as healthy as we should be. Maybe we can make fermentation convenient, maybe we can show people that it’s not hard, we can show folks that there’s food you can have that has enhanced flavors and there’s something in fermentation for everyone. 

A diet high in fermented foods increases microbiome diversity, lowers inflammation, and improves immune response, according to researchers at Stanford University’s School of Medicine.The groundbreaking results were published in the journal Cell.

In the clinical trial, healthy individuals were fed for 10 weeks, a diet either high in fermented foods and beverages or high in fiber. The fermented diet — which included yogurt, kefir, cottage cheese, kimchi, kombucha, fermented veggies and fermented veggie broth — led to an increase in overall microbial diversity, with stronger effects from larger servings.

“This is a stunning finding,” says Justin Sonnenburg, PhD, an associate professor of microbiology and immunology at Stanford. “It provides one of the first examples of how a simple change in diet can reproducibly remodel the microbiota across a cohort of healthy adults.”

Researchers were particularly pleased to see participants in the fermented foods diet showed less activation in four types of immune cells. There was a decrease in the levels of 19 inflammatory proteins, including interleukin 6, which is linked to rheumatoid arthritis, Type 2 diabetes and chronic stress. 

“Microbiota-targeted diets can change immune status, providing a promising avenue for decreasing inflammation in healthy adults,” says Christopher Gardner, PhD, the Rehnborg Farquhar Professor and director of nutrition studies at the Stanford Prevention Research Center. “This finding was consistent across all participants in the study who were assigned to the higher fermented food group.”

Microbiota Stability vs. Diversity

Continues a press release from Stanford Medicine News Center: By contrast, none of the 19 inflammatory proteins decreased in participants assigned to a high-fiber diet rich in legumes, seeds, whole grains, nuts, vegetables and fruits. On average, the diversity of their gut microbes also remained stable. 

“We expected high fiber to have a more universally beneficial effect and increase microbiota diversity,” said Erica Sonnenburg, PhD, a senior research scientist at Stanford in basic life sciences, microbiology and immunology. “The data suggest that increased fiber intake alone over a short time period is insufficient to increase microbiota diversity.”

Justin and Erica Sonnenburg and Christopher Gardner are co-authors of the study. The lead authors are Hannah Wastyk, a PhD student in bioengineering, and former postdoctoral scholar Gabriela Fragiadakis, PhD, now an assistant professor of medicine at UC-San Francisco.

A wide body of evidence has demonstrated that diet shapes the gut microbiome which, in turn, can affect the immune system and overall health. According to Gardner, low microbiome diversity has been linked to obesity and diabetes.

“We wanted to conduct a proof-of-concept study that could test whether microbiota-targeted food could be an avenue for combatting the overwhelming rise in chronic inflammatory diseases,” Gardner said.

The researchers focused on fiber and fermented foods due to previous reports of their potential health benefits. High-fiber diets have been associated with lower rates of mortality. Fermented foods are thought to help with weight maintenance and may decrease the risk of diabetes, cancer and cardiovascular disease.

The researchers analyzed blood and stool samples collected during a three-week pre-trial period, the 10 weeks of the diet, and a four-week period after the diet when the participants ate as they chose.

The findings paint a nuanced picture of the influence of diet on gut microbes and immune status. Those who increased their consumption of fermented foods showed effects consistent with prior research showing that short-term changes in diet can rapidly alter the gut microbiome. The limited changes in the microbiome for the high-fiber group dovetailed with previous reports of the resilience of the human microbiome over short time periods.

Designing a suite of dietary and microbial strategies

The results also showed that greater fiber intake led to more carbohydrates in stool samples, pointing to incomplete fiber degradation by gut microbes. These findings are consistent with research suggesting that the microbiome of a person living in the industrialized world is depleted of fiber-degrading microbes.

“It is possible that a longer intervention would have allowed for the microbiota to adequately adapt to the increase in fiber consumption,” Erica Sonnenburg said. “Alternatively, the deliberate introduction of fiber-consuming microbes may be required to increase the microbiota’s capacity to break down the carbohydrates.”

In addition to exploring these possibilities, the researchers plan to conduct studies in mice to investigate the molecular mechanisms by which diets alter the microbiome and reduce inflammatory proteins. They also aim to test whether high-fiber and fermented foods synergize to influence the microbiome and immune system of humans. Another goal is to examine whether the consumption of fermented foods decreases inflammation or improves other health markers in patients with immunological and metabolic diseases, in pregnant women, or in older individuals.

“There are many more ways to target the microbiome with food and supplements, and we hope to continue to investigate how different diets, probiotics and prebiotics impact the microbiome and health in different groups,” Justin Sonnenburg said.

Researchers from the nonprofit research center Chan-Zuckerberg Biohub also contributed to the study. Here’s the complete press release from Stanford Medicine News Center.

Forty years after the U.S. Food and Drug Administration (FDA) released its first legal definition of yogurt, the government agency has now updated that standard of identity. But, according to the International Dairy Foods Association (IDFA), this new final rule is so outdated and out-of-touch with yogurt makers that popular products could be removed from grocery store shelves. The IDFA, which represents the nation’s dairy manufacturing industry, submitted an 87-page formal objection to the FDA.

“The result is a yogurt standard that is woefully behind the times and doesn’t match the reality of today’s food processing environment or the expectations of consumers,” says Dr. Joseph Scimeca, senior vice president of IDFA’s Regulatory and Scientific Affairs. 

The IDFA is particularly concerned that the FDA crafted its final rule using comments made when the agency first pitched the guideline 12 years ago. Scimeca continues: “the final rule is already out of date before it takes effect…as if technology has not progressed or as if the yogurt making process itself has been trapped in amber like a prehistoric fossil.”

The revised standard does not include IDFA’s recommended revisions.

Dairy-Free “Vegurt”

Chr. Hansen, a global bioscience supplier of ingredients, has developed Vega Culture Kits, a new line of probiotic starter cultures that can be used to create plant-based yogurt. “Vegurt,” a shortening of vegan or vegetarian yogurt, is the name being used for this non-dairy product. This term was created in reaction to the European Parliament’s current debate over whether plant-based products can use dairy-related terms like yogurt and milk.

“Vegurt seemed a catchy and suitable category name compared to having to sprain our tongues calling them ‘fermented plant-based alternatives to dairy yogurt,’” said Dr. Ross Critenden, senior director for commercial development at Chr. Hansen. 

The Vega Culture Kits are  designed to “robustly ferment” any dairy-free plant base, like nuts, cereals, legumes or seeds. The Vega Culture will appear as “culture” on ingredient lists, in the same way that dairy yogurts include “culture” when cultures or probiotic strains are added.

“Strategic Rotting”

Fermentation saved the human diet, argues Krish Ashok, author of Masala Lab: The Science of Indian Cooking. He calls fermentation strategic rotting. The discovery of fire was key to the human’s survival as they learned to cook meat, but fermentation allowed civilization to create bread and alcohol, turn milk into yogurt and preserve a harvest through the winter. 

“Fast forward a few millennia, and we have mastered fermentation to the point where we can pick and choose microbes with precision and generate complex flavours in the bargain,” Ashok writes. Pictured, his charming drawings illustrate microbes used in fermentation.
