Rethinking Fermented Foods: More Than Just a Gut Health Supplement

I stopped recommending our ferments strictly for gut health when people started asking how much they should "take." I understand that some digestive systems need time to adjust to new foods, but it’s disheartening to see living, traditional foods like sauerkraut and kimchi reduced to tiny, medicinal doses. These are staple foods that people around the world have enjoyed for generations—yet now, we’re told to start with a teaspoon of kraut juice and slowly build up tolerance before actually eating it.

Gut Health Is a Journey, Not a Destination

Much like exercise, supporting gut health isn’t a one-time fix—it’s an ongoing commitment. You don’t “heal” your gut once and return to old habits. Our bodies function as a complex system where everything that goes in influences what comes out, including the probiotics and prebiotics we consume. Incorporating real, living foods—like sauerkraut, kimchi, kefir, vinegars, sourdough, and tempeh—shouldn’t be an occasional experiment, but a regular part of life.

Unfortunately, modern environments don’t naturally support this. Our food systems have strayed far from the wild, living foods that were once an everyday part of human diets. Unlike previous generations, we have limited exposure to soil, microbes, and the biodiversity that naturally nourished our guts. That means we need to make a conscious effort to reintroduce these foods into our lives.

A Note of Caution: Histamine Sensitivity

While fermented foods offer incredible benefits, they aren’t for everyone. Some people have histamine intolerance, which can cause headaches, skin issues, digestive distress, or other symptoms when consuming fermented foods. This is because fermentation increases histamine levels, which certain individuals struggle to break down. If you suspect histamine sensitivity, start slowly, pay attention to how you feel, and consult a healthcare professional if needed.

A Simple Approach to Eating for Gut Health

Supporting your microbiome doesn’t have to be complicated. Here are some basic principles:

• Eat smaller portions, focusing on quality over quantity.

• Reduce simple carbohydrates and ultra-processed foods.

• Eat slowly, chew thoroughly, and be mindful of your meals.

• Prioritize whole, unprocessed foods.

• Incorporate more living, fermented foods regularly.

• Eat plenty of plants and fiber-rich foods.

• Share meals and prepare food with others—it’s good for both digestion and the soul.

The Gut-Brain Connection: Mental Health Benefits

Your gut isn’t just about digestion—it plays a crucial role in mental health. Known as the "second brain," your gut houses billions of microbes that influence mood, cognition, and even emotional resilience. Studies show a strong link between gut health and conditions like anxiety, depression, and brain fog. A balanced gut microbiome can help regulate neurotransmitters like serotonin, dopamine, and GABA—chemicals that support calmness, focus, and overall mental well-being.

If you’ve ever felt sluggish, anxious, or mentally drained, your gut might be playing a role. Prioritizing whole, living foods and reducing inflammatory foods can make a noticeable difference in how you feel—both physically and mentally.

Prebiotics: Do You Really Need to Supplement?

If you’re eating a diverse, fiber-rich diet that includes living fermented foods, you likely don’t need to worry about “taking” a prebiotic. Prebiotics serve as food for beneficial bacteria, but when you consume ferments in their raw, unpasteurized form, those bacteria are already thriving. Simply put, eating a varied, plant-forward diet naturally supports your gut’s microbial balance.

For those without specific dietary restrictions or gut health conditions, the best approach is simple: prioritize whole, real foods and include ferments as often as possible. Be mindful of what you’re buying—refrigerated ferments contain live cultures, while shelf-stable versions are typically pasteurized and no longer contain active bacteria. This is the key difference between true ferments and pickled foods.

Not All Ferments Are Alive, But They’re Still Beneficial

Some fermented foods, such as sourdough, injera, dosa, tempeh, and miso, don’t contain live bacteria by the time they reach your plate because they’re cooked. However, fermentation makes them easier to digest, more nutrient-dense, and richer in complex flavors. These foods offer significant health benefits even if they’re not probiotic-rich in their final form.

Final Thoughts

To truly support your gut, aim for a diverse intake of raw, living fermented foods—small amounts, as often as possible. Enjoy the unique flavors, listen to your body, and be kind to yourself in the process. Keep moving, breathe deeply, and if possible, take time to meditate. Don’t stress about being overly clean or trying to eliminate all bacteria. Instead, stay curious—there’s a whole world of ferments out there waiting to be explored.

Find the ones you love, and make them part of your daily life.
