Gut And The Microbiome
Before we explore the realm of probiotics, it's important to gain insight into the role bacteria plays within the human body. Our bodies harbor a diverse community of bacteria, encompassing both beneficial and harmful strains, commonly known as commensal bacteria.
The beneficial bacteria serve critical functions, including the breakdown of indigestible compounds, safeguarding the body against invading pathogens, and contributing to the development of the immune system. However, it's essential to note that achieving a state of 100% beneficial bacteria within the body is practically unattainable. The majority of our microbial inhabitants, over 90% of them, and a substantial portion of our immune system, approximately 70%, reside in our gastrointestinal tract, making the gut the primary arena for immune education.
As long as the population of beneficial bacteria significantly outweighs that of harmful bacteria, the immune system can coexist with the harmful ones, maintaining a state referred to as "Eubiotic." In this Eubiotic condition, beneficial bacteria constitute 85% or more of the bacterial population. Nonetheless, factors such as excessive antibiotic usage, exposure to toxic substances in the environment, or unhealthy lifestyle choices can lead to the depletion of beneficial bacteria, particularly in the gut. This imbalance, known as dysbiosis, subsequently results in a compromised immune system.
