What Are Probiotics & Prebiotics?

Probiotics are living microorganisms that naturally exist in certain fermented foods including kefir, tempeh, miso, buttermilk, pickles, sauerkraut or pickled vegetables. They are a type of bacteria that produces lactic acid—but not to be confused with the kind of lactic acid you think of that our bodies produce after you go for a long run.

By definition, they mean “for life,” which is fitting because they are bacteria that offer health benefits to us. We have trillions of microorganisms in our bodies, and when we are healthy, these microorganisms are in good balance. Did you know? A healthy adult human has more cells of outside microorganisms inside its GI tract than it does of its own cells of the entire body combined. These microorganisms are essential to our bodies functioning properly.

Probiotics support our immune system, including our ability to fight infection, and they help us optimize our overall intestinal function, specifically the ability to absorb nutrients. Just consider how 80 percent of our entire immune system is in our digestive tract! Within our gut, probiotics improve the balance of microbes while working against any pathogens or harmful bacteria.

While more research is needed, research has supported that these beneficial bacteria may also:

Improve gut health after taking certain antibiotics
Increase our absorption of nutrients needed from food
Help our gut recover after severe stressors
Help with recovery from certain intestinal infections
Prevent or reduce the severity of colds or the flu
Synthesize Vitamin K and other beneficial substances
Aid in the proper function of our liver and thyroid

Probiotics need food that they live off, also known as prebiotics, which is why you hear of both prebiotics and probiotics together so often. In most cases, prebiotics refers to non-digestible food components such as fiber. Prebiotics are found in a variety of foods such as bananas, onions, and even artichokes. The benefits of probiotics will be maximized when we combine them with prebiotics. Yogurt and kefir are considered “symbiotic” because they combine probiotics and prebiotics.

“I Want the ‘Good’ Bacteria!”

Knowing how our gut health impacts our entire health, what does that mean for you if you’re looking to introduce more probiotics into your diet?

All of us were born with this so-called “good bacteria” present in our bodies. Our gut flora can be negatively impacted by prescription antibiotics, sugar, excess grains, stress and other chemical stressors. Because of these factors, we look to add more of the “good” bacteria to restore our natural balance within the gut.

If you’re ready to restore your gut health through probiotics, start with the foods you are eating. Depending on your other health and wellness objectives, a few options to consider include:

Sauerkraut
Kimchi
Coconut kefir
Raw and unpasteurized cheeses
High quality yogurt (many brands are low quality and full of unnecessary sugar)
Kombucha (mixed with chia seeds makes a great Probiotic and Prebiotic combination)

With so many different options (and so many companies touting their foods as being probiotic-friendly), let us help you wade through the options to find what is right for you.

Before you decide to add probiotic supplementation to your diet, ask Dr. Bradford about what is right for you. Probiotic supplements can be one of the most important and most beneficial supplements a person takes, but, not all probiotic supplements are created equal. There are several that may be beneficial and/or recommended for you depending on your needs. If a supplement is right for you, Dr. Bradford can help you set up a plan that includes an effective supplement with a synergistic blend of probiotic strains and prebiotic fibers.
