What Bread and Bacteria Taught Me in the Desert
Before deployment, I loved fermented foods. But I never made time to learn how to ferment. Then boredom hit in the desert, and I decided to finally figure it out. I wanted to master sourdough and kombucha so that when I got home, I’d be efficient.
Turns out, this wasn’t just a hobby. It was a science experiment with huge returns for recovery, performance, and gut health. My favorites so far? Sourdough bread, sourdough protein banana bread, and pomegranate kombucha. Message me for all the recipes!
What Is Fermentation? And Why Should You Care?
Fermentation has been part of the human diet for over 10,000 years. You know what hasn’t been? Gluten-free and fat-free fads.
Fermentation happens when bacteria and yeast break down carbs and transform them into acids, gases, and alcohol. That’s how I make sourdough and kombucha out here with just flour, water, tea, and sugar.
This process makes food easier to digest, lowers inflammation, and feeds the beneficial bacteria in your gut. You’re not just eating for calories. You’re feeding your microbiome, which affects digestion, recovery, sleep, focus, and immune health.
Fermentation takes basic ingredients and turns them into something powerful.
Fermentation vs. Store-Bought “Health” Foods
Let’s call it what it is. Most store-bought bread is trash. Mass-produced loaves are packed with preservatives and ultra-processed flour that spike blood sugar and drive inflammation.
Homemade sourdough is different. Long fermentation breaks down gluten and phytic acid, which improves digestion and nutrient absorption. The bacteria and yeast already do some of the heavy lifting for your gut, so you’re left with bread that feels good, not bloating.
Bonus: sourdough has a lower glycemic index, meaning steadier energy and fewer crashes. And it only takes four ingredients—flour, water, salt, and time.
My Favorite Recipe Right Now: Sourdough Protein Banana Bread
A gut-friendly recovery snack that combines fermented fuel, protein, and balanced carbs.
Ingredients (grams)
• 80 g sourdough discard (early or active)
• 200 g ripe banana (≈2 medium, mashed)
• 120 g plain Greek yogurt (protein + moisture)
• 40 g honey (natural sweetener)
• 50 g egg (1 large)
• 40 g melted coconut oil
• 5 g vanilla extract
• 100 g organic bread flour
• 60 g whole wheat flour (or heritage white flour)
• 30 g protein powder (vanilla or unflavored — whey or plant-based)
• 4 g cinnamon
• 3 g salt
• 6 g baking soda (1 tsp)
• Optional: 20–30 g shredded coconut, nuts, or dark chocolate chips
• Optional: 10 g chia or flax seeds for extra fiber
Method
■ Night Before (Fermentation)
1. Mash bananas and mix in sourdough discard, yogurt, and honey.
2. Add both flours (skip protein powder and baking soda).
3. Mix until thick and uniform.
4. Cover loosely and let ferment 8–12 hrs at room temp (if cool) or in fridge (if warm).
Next Morning
5. Preheat oven to 175 °C / 350 °F.
6. Whisk egg, oil, vanilla, protein powder, cinnamon, salt, and baking soda in a small bowl.
7. Stir this mixture into the fermented batter until just combined.
8. Fold in any add-ins. Batter should be thick but spoonable.
9. Pour into a greased loaf pan or small Dutch oven.
■ Bake
• Bake 45–55 min until a toothpick comes out clean.
• Cool at least 15–20 min before slicing
Final Thoughts:
Fermented foods can improve recovery and lower inflammation—but consistency matters more than quantity. Add a small serving of fermented food daily (like sauerkraut, yogurt, or sourdough) to support your gut and your game.
Sourdough is still a carbohydrate, so moderation matters.
Store-bought bread is built for shelf life.
Fermented bread is built for your health.
