What is a primary function of nonpathogenic bacteria in the human body?

Nonpathogenic bacteria play several beneficial roles in the human body, with one of the primary functions being to help break down food. These bacteria are crucial to the digestive system, particularly in the intestines, where they assist in the fermentation and breakdown of complex carbohydrates and other substances that our bodies cannot digest on their own. This process aids in nutrient absorption, boosting overall health.

Additionally, the presence of nonpathogenic bacteria helps maintain the balance of the microbiome, which is essential for proper digestion and can also support the immune system by preventing the overgrowth of harmful bacteria. This naturally occurring flora contributes to a healthy gut environment, ultimately enhancing nutritional uptake and contributing to overall digestive health.
