Many patients recently have been asking me the importance of probiotics and prebiotics to a healthy diet and gastrointestinal system.
For a healthy body, we need bacteria. Sounds strange! But it’s true-some of the microorganisms that live in our gut help us with vital functions. Without these untold millions of microbial species, we’d have trouble digesting foods as well as facing or dealing with immune challenges. It’s also true that some of our gut hitchhikers don’t help us and could challenge our gut as well.
Indeed, one way to promote gut balance is through the use of probiotics and prebiotics. These are products that work with your body to keep the gut environment healthy.
Probiotics – “Good” Bugs
Probiotics are live beneficial bacteria that help support normal balance in the intestinal tract. By adding these bacteria to the digestive tract, there are a number of ways they would improve the gut environment:
They could take up space in the gut, leaving less “free” space for other bacteria.
Interfere with the growth or activity of other bacteria.
Help change the pH of the gut so that it is less hospitable to other types of bacteria.
Support the cells and mucus of the gut.
Attached to other bacteria as they can’t attach to the gut wall.
Probiotic bacteria can be found at a range of products. But when deciding which product is best for you it’s important to determine whether it contains research-supported strains. By using probiotic strains with the research behind them, you can trust that the product is effective and high quality.
Prebiotic – Food for the “Good” Bugs
These are indigestible carbohydrates, used by beneficial bacteria as food. They support a favorable gut environment by selectively stimulating the growth of your unique beneficial bacteria (including Bifidobacteria and Lactobacillus). Different bugs prefer different prebiotics -for example Bifidobacteria (found primarily in the colon) seem to prefer GOS, a natural prebiotic originally found in breast milk.
In addition, prebiotics promote gut colonization by desirable bacteria, energize colon cells, improve immune system function and mineral absorption, and help intestinal gene expression and cell differentiation (the process that allows cells to become more specialized).
So, without a doubt, if you’re not taking any probiotics or prebiotics to help promote a healthy gastrointestinal tract then you should be!
