Prebiotic fiber can also increase your body’s ability to absorb certain minerals, such as calcium and magnesium. In your intestine, prebiotics are fermented by your good bacteria to produce short-chain fatty acids, which can then boost your body’s metabolic health. In fact, it essentially acts as food for the good bacteria. Prebiotic fiber is non-digestible fiber that helps support the growth of good bacteria in your gut. So, where does prebiotic fiber come into play? It turns out it’s also important for the health of the rest of your body, too, since all the nutrients your body needs must first go through the gut. Making sure your gut has enough of the right kinds of bacteria is important for the health of your gut and gastrointestinal system generally. Your gut microbiome consists of trillions of living microorganisms – a mix of what some would call good and bad bacteria. Let’s take a quick step back for those of you who might not know much about gut health. If you don’t already, you should also think of prebiotics. When you think of gut health, you might think of probiotics, which are the living microorganisms in your gut that influence the health of your gut microbiome.
