Did you know that a simple jar of fermented cabbage can contain more probiotics than a bottle of store-bought supplements? Fermentation isn’t just an ancient tradition—it’s a science-backed way to boost your gut health. One of my favorite books on the science of this topic is The Life Bridge: The Way to Longevity with Probiotic Nutrients, which explores how microbes transform minerals into powerful health-promoting nutrients. As I write my own book—The Microbial Code: Unlocking the Secret to Life with Probiotic Nutrients—one that builds upon and updates the science from the last 20 years, I am excited to share how microbes foster life, how environmental chemicals are disrupting these processes, and what you can do to restore your gut, your minerals, and your health. My book will also include a guide to fermented foods from around the world, key microbes for health, and practical ways to cultivate a thriving gut microbiome and source a host of friendly microbes.
The Transformative Power of Fermentation
Fermentation is an age-old practice that not only preserves food but also enhances its nutritional value and introduces beneficial probiotics into our diet. A pivotal figure in the modern fermentation revival is Sandor Ellix Katz. After facing serious health challenges, Katz turned to traditional fermented foods, which played a significant role in his healing journey. His seminal work, The Art of Fermentation, offers an in-depth exploration of various fermentation processes and their benefits. You can learn more about his work and access a wealth of resources on his official website: wildfermentation.com.
One of the most accessible ways to experience the power of microbes firsthand is through fermentation. Let’s explore how simple it can be to start your own probiotic-rich foods at home.
Getting Started with Fermentation
For those new to fermentation, here are some accessible and rewarding probiotic-rich foods to begin with:
1. Sauerkraut and Kimchi
Fermenting cabbage into sauerkraut or its spicy counterpart, kimchi, is a straightforward process that yields flavorful results rich in lactic acid bacteria, supporting gut health.
2. Sourdough Bread
Creating a sourdough starter involves cultivating wild yeasts and bacteria to naturally leaven bread. This method not only imparts a unique flavor but also fosters a sense of community, as sharing starter cultures has become a cherished tradition among bakers.
3. Kefir
Kefir is a fermented milk drink teeming with a diverse array of beneficial microbes. Its complex microbial community works synergistically to promote digestive health. Kriben Govender, a food scientist and founder of NourishMe Organics experienced a profound personal transformation through kefir. Facing severe depression and health issues, Kriben turned to homemade fermented foods like kefir, which significantly improved his mental and physical well-being. He now shares his journey and knowledge through the Gut Health Gurus Podcast, aiming to help others harness the benefits of fermentation.

4. Kombucha and Jun Tea
Both kombucha (fermented tea with a SCOBY) and jun (a honey-based version) are fantastic ways to introduce probiotics and beneficial acids into your diet. The fermentation process also produces unique organic acids that support detoxification.
Cabbage Water: A Nutrient Powerhouse
Think oranges are the best source of vitamin C? Think again. Fermented cabbage packs even more of this immune-boosting nutrient—and it’s incredibly easy to make at home. Cabbage water is rich in nutrients and antioxidants, offering a range of health benefits, including reducing inflammation and boosting the immune system. Fermentation increases the vitamin C content exponentially. Fermented cabbage has more vitamin C than an orange. Purple/red cabbage even more!
Key Antioxidants in Cabbage Water
- Vitamin C: Supports the immune system and fights free radicals.
- Anthocyanins: Found in purple/red cabbage, these plant pigments may reduce the risk of heart disease.
- Indoles: Found in cabbage juice, these antioxidants may have anticancer properties.
Other Benefits of Cabbage Water
- Fiber: Promotes regular bowel movements.
- Potassium: Helps the body get rid of excess sodium through urine.
- Vitamin K: Helps the body fight bone breakdown and improves bone strength.
- Sulfur: Helps form keratin, which is required for healthy hair, nails, and skin.
Ways to Use Cabbage Juice
- Drink a shot of cabbage juice chilled.
- Dilute fermented cabbage juice with water and sip.
- Use cabbage juice topically to improve complexion.
- Cabbage in General
- Cabbage is a cruciferous vegetable primarily green, white or purple/red
- It is frequently used in dishes such as salads and sandwiches.
- Cabbage may help heal wounds and reduce swelling.

Microbial Communities: A Lesson in Harmony
Fermentation showcases the harmonious collaboration of diverse microbial communities. In kefir, for instance, bacteria and yeasts coexist, each contributing to the ecosystem's balance and health benefits. This symbiotic relationship serves as a powerful metaphor for human societies, illustrating how cooperation and diversity can lead to resilience and well-being.
Begin Your Fermentation Adventure
Starting your own fermentation projects is a fulfilling endeavor that connects you to ancient traditions and promotes health. Whether it's crafting your own kefir, baking sourdough bread, or fermenting vegetables, the process is both educational and nourishing. As you gain confidence, consider sharing your creations and even your starter cultures with friends and family, fostering community and well-being.
Simple Wild Fermentation Recipe
Simple Countertop Sauerkraut Ingredients:
- 1 medium head of organic cabbage*
- 1 tablespoon sea salt
Instructions:
- Finely shred the cabbage and place it in a large bowl.
- Sprinkle the salt over the cabbage and massage it with your hands until it begins to release liquid.
- Pack the cabbage tightly into a clean glass jar, pressing down to submerge it in its own brine.
- Cover loosely and let ferment at room temperature for 1-2 weeks, checking daily to ensure the cabbage remains submerged.
- Taste and refrigerate when the flavor reaches your preferred tanginess.
Are you ready to embark on your fermentation journey? Which probiotic-rich food will you start crafting this spring?
*If you can’t get an organic cabbage you may be missing the living organism that will ferment the cabbage. If you are concerned about this you can add 1 capsule of Sugar Shift which contains many of the cultures found in sauerkraut to “seed” your kraut.
