Microbiome and Mental Health

Microbiome and Mental Health

The concept that gut bacteria influence our mood and mental health. Through the 'gut-brain axis,' microorganisms in the intestines play a role in our emotional responses and stress reactions.

What is the Microbiome and Mental Health?

Trillions of microorganisms live inside our bodies. Research is increasingly showing that the gut microbiome influences not only digestion, but also our mood, emotions, and stress responses.

The Gut-Brain Axis

Mindy has a fascinating story to share with you. The gut and brain are directly connected through the vagus nerve. Gut microbes can send signals to the brain through this pathway. Did you also know that approximately 90% of serotonin is produced in the gut? Serotonin is a key neurotransmitter that regulates mood.

How Gut Microbes Affect the Mind

When the balance of the gut microbiome is disrupted, various psychological changes can occur:

  • Increased inflammatory substances: Can trigger brain inflammation and heighten feelings of depression
  • Changes in neurotransmitters: Affects the production of serotonin, GABA, and other chemicals
  • Altered stress responses: Influences the activation of the HPA axis
  • Mood changes: Lower diversity of gut microbes may increase the risk of anxiety or depression
  • Lifestyle Habits for Gut Health

  • Eat diverse dietary fiber: Fruits, vegetables, and whole grains serve as food for beneficial bacteria
  • Fermented foods: Kimchi, yogurt, and miso help replenish good bacteria
  • Stress management: Stress alters the gut environment
  • Adequate sleep: Sleep deprivation disrupts the balance of gut microbes
  • Avoid unnecessary antibiotic overuse: Beneficial bacteria can be reduced along with harmful ones
  • To care for your mind, it helps to also tend to your gut health. The body and mind are far more closely connected than you might think.

    💡 Real-Life Example

    If you've noticed that you feel unusually low or anxious when your gut health is poor, it may be the influence of the microbiome through the gut-brain axis.
