Prebiotics: The Way To A Happy Microbiome

When it comes to maintaining gut health and digestion your first thought may be to reach for a probiotic supplement or to increase your fiber intake. However, what is often overlooked is the role of not only probiotics but prebiotics and all their beneficial properties. The environmental space of the gut is called the microbiome and to keep your gut happy and healthy and free of unwanted pathogens it requires the right balance of probiotics as well as prebiotics. Probiotics are live microorganisms that have a positive effect on gut health and aid in treating gastrointestinal disorders, improving symptoms of IBS, and allergic disorders, function as an anti-inflammatory agent, and have a positive impact on the body’s immune system. With all the benefits of probiotics you may be wondering just how do they thrive in our microbiomes and work to keep us healthy? That is where prebiotics come into play.

What are prebiotics and what do they do?

In general, prebiotics are indigestible fibers. When we eat them, they can alter the population of our gut microbiome by serving as food for organisms that live there, encouraging the good bacteria to thrive and starving off or crowding out the bad.

The advantage of maintaining a healthy gut microbiome via prebiotics, rather than relying on probiotic supplements, is that the balance of is maintained naturally over time. Probiotic supplements can be helpful when addressing a specific and/or acute issue. By using the prebiotics in food to address gut health, we enhance our bodies’ ability to find their own healthy balance!

Maintaining a healthy population of probiotics, or good bacteria, in the gut has a range of benefits, including:

– Reduced risk of certain cancers and tumors

– Immune system support

– Protection against infections

– Prevention of IBD and obesity

– Help in lowering cholesterol
