Examples: Common probiotic strains include Lactobacillus acidophilus, Bifidobacterium bifidum, Lactobacillus rhamnosus, and Saccharomyces boulardii.
Prebiotics:
Definition: Prebiotics are non-digestible fibers and carbohydrates that serve as food for beneficial bacteria in the gut microbiota. They help promote the growth and activity of probiotics and support overall gut health.
Sources: Prebiotics are found naturally in certain foods, including chicory root, Jerusalem artichokes, garlic, onions, leeks, asparagus, bananas, apples, oats, and flaxseeds. They can also be added to foods and beverages as functional ingredients.
Health Benefits: Prebiotics help nourish beneficial bacteria in the gut, enhance the production of short-chain fatty acids (SCFAs), improve gut barrier function, and modulate immune responses. They may also support regularity, reduce inflammation, and improve metabolic health.
Examples: Common prebiotic fibers include inulin, fructooligosaccharides (FOS), galactooligosaccharides (GOS), resistant starch, and soluble fiber from sources like psyllium husk, oats, and legumes.
