Prebiotics Defined as Substrates for Beneficial Gut Microorganisms, Offering Health Benefits
Prebiotics are identified as substrates that are selectively utilized by host microorganisms, leading to health benefits. These are typically types of fiber that specific gut microbes can ferment and use as fuel. Examples include inulin and other fermentable fibers. Unlike probiotics, prebiotics are not living organisms; instead, they serve as nourishment for existing beneficial bacteria within the gut. This support for beneficial gut bacteria contributes to overall health. The concept highlights that while probiotics introduce live microorganisms, prebiotics provide the necessary sustenance for these and other beneficial microbes to thrive and function effectively within the digestive system.
