Your gut is home to trillions of bacteria—collectively called the gut microbiome—that influence everything from digestion to immune function to mental health. Understanding and supporting this ecosystem is foundational to overall wellness.
What the Microbiome Does
- Digest certain fibers and produce short-chain fatty acids
- Synthesize vitamins K and B12
- Train and regulate the immune system
- Produce neurotransmitters (95% of serotonin is gut-produced)
- Protect against harmful pathogens
- Influence metabolism and body weight
What Harms the Microbiome
- Antibiotics (necessary sometimes, but disruptive)
- Processed foods and artificial sweeteners
- Chronic stress
- Poor sleep
- Low fiber intake
How to Support Gut Health
- Eat diverse fibers: Prebiotic foods (garlic, onions, asparagus) feed beneficial bacteria
- Include fermented foods: Yogurt, kefir, sauerkraut, kimchi add beneficial bacteria
- Eat polyphenol-rich foods: Berries, tea, dark chocolate feed good bacteria
- Minimize artificial sweeteners: Some evidence suggests they harm the microbiome
