Infectious Diseases, Microbiology & Beneficial Microbes

Probiotics and Prebiotics

Probiotics and prebiotics both support gut health but function differently. Probiotics are live microorganisms, typically bacteria or yeast, that confer health benefits when consumed in adequate amounts. These beneficial microbes are similar to those naturally found in the gut and are present in foods like yogurt, kefir, sauerkraut, kimchi, and in supplement form. They help maintain a healthy gut flora by encouraging the growth of beneficial bacteria and suppressing harmful ones. Probiotics have been linked to improved digestion, enhanced immune function, relief from irritable bowel syndrome (IBS), and even mental health support.

Prebiotics, on the other hand, are types of fiber that nourish beneficial gut bacteria. They are not digested by the human body but pass through to the colon, where they are fermented by gut bacteria, producing short-chain fatty acids that fuel colon cells and support gut health. Found in foods like bananas, onions, garlic, leeks, asparagus, chicory root, and whole grains, prebiotics work synergistically with probiotics to promote overall well-being.
