Most bacteria in the human body are beneficial and essential for health.
Here's why:
* Trillions of bacteria live on and inside us. They are collectively known as the human microbiome.
* The majority are beneficial. They help with digestion, immune system development, and protection from harmful bacteria.
* Some bacteria are neutral. They neither help nor harm us.
* A small minority are harmful. These can cause infections and diseases.
Therefore, while we often associate bacteria with illness, the vast majority of bacteria in our bodies are actually crucial for our well-being.
