The human body can be thought of as a micro-ecosystem, which includes our own cells as well as a huge number of microorganisms. It is estimated that our bodies house trillions of microorganisms, including bacteria, fungi, viruses, etc., which far exceed the number of our own cells. These microorganisms form a mutually beneficial symbiotic relationship with our human hosts, working collaboratively with our bodies to maintain ecological balance.
In recent years, an increasing number of studies have revealed the close connection between these microorganisms and our growth and development, digestion and absorption, regulation of the immune system, metabolic processes, and emotional and mental health. They are involved in regulating immune responses, helping us digest food, synthesize necessary vitamins and other biochemicals, and maintain the health of the intestinal mucosa. This synergy between microorganisms and the human body is crucial to maintaining overall health, making us more aware of the importance of microorganisms within the human body.
Because of this, probiotics have become famous in the nutritional market and can definitely be regarded as the new favorite of human health in recent years. A growing body of research also shows that probiotic-rich foods and supplements show the potential to prevent and treat many health problems and diseases, from gastrointestinal disorders to brain disorders, allergies, and even cancer. etc.
The earliest use of probiotics may date back to ancient times. When human ancestors switched from hunting and gathering to agriculture 11,000 years ago, they may not have realized it yet, but they had already started using probiotics at that time. At that time, farmers used to store excess food. Once you store food, microorganisms will continue to multiply on the food. Sometimes, the stored food will ferment. The so-called fermentation is a process in which microorganisms continue to grow, decompose food into various metabolites, and make the food rich in probiotics. The fermentation process not only extends the storage time of food but also makes it easier for the body to digest and absorb.
The human micro-ecosystem is a complex and sophisticated symbiotic relationship that has a profound impact on many aspects of our health and life. Research on this ecosystem is continuing to expand our understanding of how the body works, providing new possibilities for future medicine and health management.
