The microbiome is one of the most important foundations of our health. These microbes support digestion, nutrient absorption, create a barrier against invaders, neutralize toxins, regulate immune responses, control inflammation, and produce vital vitamins and neurotransmitters that influence our brain. Often called the ‘second brain,’ the gut contains its own nervous system, the enteric nervous system which connects to the brain through the Vagus nerve. This gut-brain axis allows microbes to influence mental health as chemical messengers that are either calming or inflammatory. An inflamed gut equals an inflamed brain.

When microbes digest fiber, they produce short fatty chain acids (SCFAs)which include butyrate. Butyrate helps ‘plug leaks’ in the gut lining.  When the microbiome becomes imbalanced, known as gut dysbiosis, the gut lining can become permeable (leaky gut), allowing toxins and food particles to leak into the bloodstream. This triggers systemic inflammation and contributes to food sensitivities, autoimmune conditions, and mental health issues. Healthy gut bacteria produce essential brain chemicals like serotonin, dopamine, GABA, glutamate, and BDNF, Ninety percent of serotonin is made in the gut. 

GABA calms the nervous system and normalizes brain waves. BDNF supports the growth and protection of brain cells, and glutamate is crucial for learning and memory.

Without a diverse microbial community, harmful bacteria can take over. Antibiotics, which are not selective, can wipe out the entire microbiome, taking years to replenish. It can allow antibiotic resistant strains like Clostridium difficile to gain a foothold, which has been linked to Autism and chronic diarrhea. ADHD is a manifestation of a deficient microbiome leading to leaky gut and chronic inflammation from triggers like gluten, affecting the brain response. All health conditions begin in the gut and start with microbial imbalance. 

Many factors begin at birth including C-sections, bottle feeding and antibiotics. Other contributors are poor diet, artificial sweeteners, gluten, NSAIDs and antibacterial products that absorb through the skin. Yet, we can rebuild our microbiome. We must consider we are not only eating for ourselves but our microbes.

Include fermented foods like kefir, kombucha, pickled vegetables, and yogurt with live cultures. Take quality probiotics containing Lactobacillus and Bifidobacterium. Which are important for mental health and the more you have will crowd out pathogenic bacteria like Candida. Consider probiotic enemas if you've had repeated antibiotics. Feed your microbes prebiotic foods high in inulin like onions, garlic, leeks, artichokes, chicory, and dandelion greens. Resistant starches reach the colon fully intact to feed good bacteria, found in legumes, grains, unripe bananas, green peas and rice that has been cooked and cooled. Other sources of fiber include oats, flaxseed, apples and psyllium husk. For severe conditions, FMT (fecal microbial transplants) have shown to make drastic improvements. 

As the microbiome gains more popularity, there are companies you can send out your stool to have your microbiome analyzed. A healthy gut truly leads to a healthy mind and body.
