Your gut and your brain are in constant conversation. Scientists call it the gut-brain axis — a bidirectional communication network linking your enteric nervous system (the 100 million neurons lining your digestive tract) with your central nervous system. What happens in your gut doesn't stay in your gut.
Research now links gut microbiome health to mood regulation, anxiety, cognitive function, and even sleep quality. The good news? What you eat has a profound influence on the diversity and health of your gut bacteria — and two of the most powerful tools are fermented foods and bone broth.
Why Gut Diversity Matters
A diverse microbiome — one with a wide variety of bacterial species — is associated with better mental health outcomes, stronger immune function, and reduced inflammation. Fermented foods introduce beneficial live bacteria (probiotics) that help maintain and restore this diversity.
Fermented Foods: Your Gut's Best Friends
Traditional fermented foods have been part of human diets for thousands of years. At HOTRO, we make our own in-house:
- HOTRO Golden Sauerkraut — naturally fermented, rich in Lactobacillus strains that support gut lining integrity
- HOTRO Ruby Kraut — red cabbage, beet & apple sauerkraut, house-made in Gibsons, BC, with added antioxidants from beet and apple
Our Gut Hut collection also includes krauts, kimchi, fermented drinks and tonics, and koji ferments — a full spectrum of probiotic-rich foods to rotate through your diet.
Bone Broth: Healing the Gut Lining
While fermented foods add beneficial bacteria, bone broth works differently — it helps repair and maintain the gut lining itself. The collagen, gelatin, and amino acids (particularly glycine and glutamine) extracted during slow simmering are the building blocks of the intestinal wall.
A healthy, intact gut lining is critical for preventing "leaky gut" — a condition where undigested particles pass through the intestinal wall into the bloodstream, triggering systemic inflammation that can affect mood and cognition.
Our Nourish Yourself Bone Broth range includes:
- Beef Bone Broth — rich in collagen and minerals, deeply restorative
- Chicken Bone Broth — lighter, high in glycine, great for daily use
- Turkey Bone Broth — naturally high in tryptophan, a precursor to serotonin
- Vegetable Defender Broth — for a plant-forward gut-support option

The Serotonin Connection
Here's a striking fact: approximately 90% of your body's serotonin — the neurotransmitter most associated with mood and wellbeing — is produced in the gut, not the brain. This means that a healthy gut microbiome isn't just good for digestion; it's foundational to emotional resilience and mental clarity.
A Simple Daily Protocol
- Morning: a warm cup of Chicken Bone Broth to start the day with gut-healing glycine
- With meals: a tablespoon of Golden Sauerkraut or Ruby Kraut as a condiment
- Evening: Turkey Bone Broth — its natural tryptophan content may support relaxation and sleep
Your gut is your second brain. Feed it accordingly.
