Understanding Prebiotics
Definition and Function of Prebiotics
Prebiotics are specialized plant fibers that serve as nourishment for the beneficial bacteria residing in the gut. Unlike other nutrients, prebiotics resist digestion in the upper gastrointestinal tract and reach the colon intact. Once in the colon, they undergo selective fermentation by beneficial microflora, which helps in changing the composition of the colonic microbiota.
The primary function of prebiotics is to stimulate the growth and activity of advantageous bacteria like bifidobacteria and lactobacillus. These bacteria play a crucial role in maintaining gut health by improving digestion, enhancing the immune system, and producing short-chain fatty acids that provide energy to the cells lining the colon (Healthline).
