How Much Fermented Food Does the Average American Eat?

When you think of kimchi, sauerkraut, yogurt, kombucha, or miso, you’re probably picturing flavors, textures, and culinary traditions rooted in different parts of the world. But there's a growing trend in the United States — one that revolves around the consumption of fermented food and beverages, and its connection with gut health, microbial diversity, and overall well-being.

But how much fermented food and beverage does the average American actually consume? Is it a regular staple or just an occasional addition to meals? Let’s explore this flavorful topic, backed by consumer trends, evolving food preferences, and some insights into the fascinating world of fermented fare.

A Look at American Eating Habits

To understand the intake of fermented foods and beverages in the U.S., we first need to recognize how eating patterns have evolved over the decades. Traditionally, many Americans leaned toward processed, convenience-oriented foods, especially during the post-war boom of the 1950s. However, in recent years, there has been a noticeable shift toward whole, natural, and functional foods.

Fermented products are gaining recognition due to their role in supporting the gut microbiome. As consumers become more aware of what they’re putting on their plates, eating fermented foods has moved from niche to mainstream. Still, when compared globally — especially with countries like Korea (kimchi), Germany (sauerkraut), or Japan (miso and natto) — Americans are only just catching up.

What the Numbers Say

Precise nationwide data on the average American’s intake of fermented food is still limited, but several consumer research reports offer insight:

• A 2023 survey by the International Food Information Council noted that around 30% of Americans reported consuming fermented foods like yogurt, kefir, or kombucha at least once per week.
• Yogurt remains the most commonly consumed fermented dairy product, often incorporated into breakfasts or smoothies.
• Kombucha, a fizzy fermented tea, has shown a 500% increase in sales between 2015 and 2022, signaling greater interest in fermented beverages.
• Miso, kimchi, fermented vegetables, and tempeh remain less common in American households but are gradually entering mainstream grocery shelves.

On average, it's estimated that Americans consume about 2 to 3 servings of fermented foods per week — primarily yogurt, pickles, and kombucha. While that may seem promising, many experts suggest this frequency is still relatively low, especially when considering the global emphasis on probiotic and prebiotic intake for supporting microbial diversity in the gut.

Fermented Foods on the Rise

So what’s fueling the growing consumption of fermented food in the United States?

1. Awareness of Gut Health and Microbial Diversity

The term gut microbiome is now a part of everyday conversations. While it was once limited to scientific journals, today it’s popping up in social media wellness tips, documentaries, and grocery store labels. Americans are increasingly interested in the role of food in supporting overall health, particularly through the lens of digestion and internal balance.

2. Influence of Global Cuisines

The introduction of kimchi, sauerkraut, miso, and fermented soybean products through Asian and European cuisine has introduced Americans to new flavors and traditions. Korean restaurants, German delis, and Japanese ramen bars often include these fermented vegetables as standard sides or toppings.

3. Scientific Association for Probiotics and Fermentation Advocacy

Organizations like the Scientific Association for Probiotics and Prebiotics have played a role in bringing scientific clarity to the public. By distinguishing between probiotic and prebiotic foods and emphasizing the importance of active cultures, they help demystify how and why people might choose to consume fermented foods.

A Diversity of Fermented Options

Let’s explore some popular types of fermented food and beverage choices in the American market:

Yogurt and Kefir

These are by far the most widely consumed fermented dairy products in the U.S. Many brands highlight their active cultures or strains of bacteria on packaging, appealing to consumers focused on gut-conscious choices.

Kimchi and Sauerkraut

While not yet staple items in every household, these fermented vegetables are gaining traction. Their tangy flavor and crunchy texture make them excellent sides, toppings, or salad additions.

Kombucha

This fermented beverage, made from sweet tea and a symbiotic culture of bacteria and yeast (SCOBY), is especially popular among millennials and Gen Z consumers. Available in a variety of flavors, kombucha sales are booming in health food stores and mainstream supermarkets.

Pickles and Fermented Cucumbers

It’s important to note that not all pickles are fermented. Many commercial varieties are vinegar-brined. However, traditionally fermented pickles (those made with just saltwater and time) are enjoying a slow but steady comeback.

Miso and Tempeh

Used primarily in plant-based and Asian-inspired dishes, these items are more likely to be found in niche grocery stores or specialty aisles. Their popularity is growing, especially among vegetarian and vegan consumers.

Why Aren’t Americans Eating More?

Despite increased awareness, many Americans still do not consume fermented foods on a daily basis. Several factors influence this:

• Taste Preferences: Not everyone enjoys the tangy, pungent flavors typical of fermented fare.
• Lack of Familiarity: Some people are unsure how to prepare or incorporate items like kimchi, tempeh, or miso into everyday meals.
• Misunderstanding of Labels: The term “fermented” isn’t always clear on packaging. Products labeled as “pickled” might not contain active cultures, leading to confusion.
• Cultural Gaps: In countries where fermentation is a culinary tradition, such as Japan or Korea, children grow up eating these foods. In the U.S., these habits are only starting to form.

Building a Fermented Future

Looking ahead, food industry analysts predict that the intake of fermented foods and beverages in the United States will continue to climb, driven by:

• Education: As consumers better understand terms like probiotic and prebiotic, and how they relate to gut health, demand is likely to grow.
• Product Innovation: Brands are creating new ways to make fermented food and beverage more palatable — think fruit-infused kefir, sparkling probiotic drinks, or kimchi-flavored snacks.
• Restaurant Influence: Chefs are experimenting with fermentation techniques, making it trendy and accessible through fusion menus and food trucks.
• Sustainability Trends: Fermentation is a natural preservation technique, which aligns with efforts to reduce food waste and support environmentally friendly food practices.

Fermented Foods Beyond the Plate

Fermentation is more than a flavor booster — it’s a tradition rooted in preservation, transformation, and community. Across cultures and generations, it has allowed societies to make the most of seasonal harvests, enhance flavor profiles, and store food safely.

In the U.S., there is now a movement not only toward eating fermented foods, but also toward home fermentation. DIY enthusiasts are making their own sourdough bread, kombucha, and fermented vegetables, often sharing recipes and starter kits online. These efforts strengthen not only individual food choices but also cultural curiosity and culinary skill.

How to Incorporate More Fermented Foods Into Your Diet

If you're one of the many Americans curious about increasing your consumption of fermented food, here are a few easy ways to start:

• Start with Yogurt or Kefir: Choose options that list active cultures on the label.
• Add Sauerkraut to Sandwiches: It adds crunch and flavor without needing extra preparation.
• Mix Miso Into Dressings or Soups: It’s salty, savory, and works well in small amounts.
• Snack on Fermented Pickles: Make sure they’re naturally fermented and not just vinegar-soaked.
• Experiment with Kimchi Fried Rice: A flavorful and easy way to include fermented vegetables in your meal.
• Try Kombucha as an alternative to soda or sugary drinks.

It doesn’t take much — just a few servings each week can introduce you to the complex, bold flavors that define fermentation.

The American Fermentation Landscape: A Work in Progress

While it’s clear that the average American’s intake of fermented foods is still modest compared to global standards, the trajectory is upward. As more people become aware of their gut microbiome, and as scientific and culinary communities continue to advocate for broader adoption, the culture of fermentation is steadily growing roots in American kitchens.

Whether you’re picking up a jar of artisanal kimchi from your local market or brewing kombucha in your kitchen, your efforts to consume fermented foods contribute to a food movement that is flavorful, diverse, and increasingly appreciated.

Conclusion

In summary, the consumption of fermented food in the United States is increasing — though the average intake remains lower than in cultures with long-standing fermentation traditions. With the help of organizations like the Scientific Association for Probiotics, the growing interest in gut health, and the influence of global cuisines, eating fermented foods is becoming more commonplace. From dairy products and fermented vegetables to bubbly fermented beverages, these foods are stepping out of the shadows and into mainstream meals.

Fermentation isn't just a trend — it’s a rediscovery. A celebration of tradition. And in America, it’s only just beginning.
