Prebiotics and probiotics (P&P) are both important for maintaining gut health.
P&P function differently.
Probiotics are live microorganisms that, when administered confer health benefits on the host.
Probiotic benefits include modulation of the intestinal microflora, enhancement of the immune system, and prevention of gastrointestinal infections such as rotavirus-induced diarrhea and antibiotic-associated diarrhea.
Common probiotic strains include Lactobacillus, Bifidobacterium, and Saccharomyces bollard.
Prebiotics, on the other hand, are non-digestible food ingredients that selectively stimulate the growth or activity of beneficial bacteria in the colon, such as bifidobacteria and lactobacilli.
Prebiotic fermentation leads to a beneficial shift in the gut microbiota composition, which can improve gut health and potentially reduce the risk of certain diseases.
Common prebiotics include inulin, fructo-oligosaccharides, and galacto-oligosaccharides.
The American Gastroenterological Association (AGA) defines prebiotics as substances that are selectively utilized by host microorganisms conferring a health benefit.
The AGA indicates probiotics are live microorganisms that confer health benefits when administered in adequate amounts.
Prebiotics are specialized plant fibers that act as food for beneficial gut bacteria.
Prebiotics: Foods like onions, garlic, bananas, chicory root, and Jerusalem artichokes
Complex carbohydrates and fiber that your body can’t digest but gut bacteria can use.
Compounds called oligosaccharides and inulin
Probiotics are the actual living beneficial microorganisms that help maintain a healthy gut environment.
These include: Bacteria strains like Lactobacillus and Bifidobacterium Found naturally in fermented foods like yogurt, kefir, sauerkraut, and kimchi Also available as dietary supplements
The relationship between P&P is synergistic – prebiotics feed and support the growth of probiotic bacteria.
Benefits of maintaining healthy levels of both P&P. – Improved digestion and nutrient absorption – Stronger immune system function – Potential reduction in inflammation – Better mental health through the gut-brain axis) – More regular bowel movements
