So, what does modern science say about the importance of our gut health? Remarkably, the wisdom of Donguibogam is being proven with greater precision through advanced scientific fields such as modern neurology, endocrinology, and immunology. Modern medicine views the gut beyond an organ merely responsible for digestion, regarding it as a second brain and the control tower of immunity that governs the health of the entire body.
Did you know that over 100 trillion microorganisms live inside our intestines? Like a massive ecosystem, these microorganisms are intricately intertwined with beneficial bacteria, harmful bacteria, and neutral bacteria to form the gut microbiota ecosystem. The collapse of this balance is called gut dysbiosis, and this imbalance is pointed to as a core cause of decreased immunity.
The gut is home to gut-associated lymphoid tissue, where about 70% of our body’s immune cells are concentrated. A healthy gut microbiota supports the immune system in diverse ways, including blocking the invasion of external pathogenic bacteria, educating immune cells, and regulating inflammatory responses. Beneficial bacteria produce beneficial substances such as short-chain fatty acids to strengthen the intestinal mucosa, inhibit harmful bacteria proliferation, and secrete immunomodulators that positively influence systemic immunity. However, if the intestinal environment worsens, this vital defense line collapses, and leaky gut syndrome, characterized by increased intestinal mucosal permeability, can occur. Countless studies consistently show that when toxins or microbial fragments penetrate into the bloodstream through gaps in the intestinal barrier, they induce systemic inflammation and can even raise the risk of autoimmune diseases or allergic diseases.
Even more remarkable is the gut-brain axis theory, which states that the gut is closely connected to the brain. The gut communicates constantly with the brain through numerous nerve cells and neurotransmitters. It is now widely known that more than 90% of serotonin, known as the happiness hormone, is produced in the gut. Gut dysbiosis affects the production of these neurotransmitters and is said to be deeply linked to various mental health issues such as depressive feelings, anxiety, and sleep disorders. Feeling moody and tired for no apparent reason was not without cause, was it?
Chronic fatigue, skin trouble, dyspepsia, and even emotional fluctuations. If you thought these symptoms were separate issues, you now need to view them within the single big picture of gut health. Our intestines are organically connected to every system in the body, and when the balance of the gut microbiota collapses, other health problems can occur in a chain reaction like falling dominoes. Please remember that your intestines are not just a place that digests food, but the most important sentinel protecting the health of your body and mind.
