I talk about probiotics a lot. I even have a PBS show on the topic—The Road to Perfect Health. I call your gut bacteria the Gut Protection System, or GPS. The word probiotics means, “for life.” Probiotics are defined as beneficial bacteria (sometimes yeast) that benefit the person taking them in some way. Many people relate probiotics to yogurt, because some yogurts contain probiotics. (Many don’t—if the probiotics aren’t added back in after pasteurization, there won’t be any probiotics in the yogurt due to high heat required during pasteurization. Plus, check the sugar levels in yogurt—yikes!)
Awareness of probiotics is increasing. In 2007, about 58 percent of people surveyed were aware probiotics might be good for the digestive system. In 2011 that percentage increased to 81 percent. People are starting to get it.
What about prebiotics? Prebiotics are non-digestible food ingredients that promote the growth of beneficial microorganisms (like probiotics) in the gut. They are essentially food for the beneficial gut bacteria—the fuel for the Gut Protection System, if you will. Prebiotics are often soluble fibers, like FOS (fructo-oligosaccharides) and acacia fiber.
If you think about it, soluble fibers escape digestion, arriving in the colon (large intestine) largely intact. Then, beneficial bacteria use the soluble fibers like food. A fermentation process occurs, yielding beneficial compounds like the short-chain fatty acid, butyrate, which fuels intestinal lining cells, and lactic acid, which lowers the colon pH to a healthy level.
Prebiotics and probiotics go hand-in-hand. When these two are found together, they are often called a “synbiotic,” highlighting their beneficial relationship. Studies show that the prebiotic FOS is particularly helpful in increasing levels of beneficial gut bacteria, while inhibiting an increase in harmful bacteria.
If you’re taking a prebiotic, be sure to take it with a probiotic to get the added benefit and to ensure you’re giving the “food” to the right kind of bacteria—the good kind.
I like to call the proper balance of gut bacteria your “GPS”—your Gut Protection System. Your GPS works to: protect your intestinal lining; “crowd out” and neutralize the harmful bacteria; and influence the immune system so that it responds in the proper way to harmful invaders like bacteria, toxins, and even undigested food particles.
Your GPS might not be properly balanced—and you may not even know it. Sure, some people experience obvious digestive symptoms like gas and bloating, or heartburn, but some people don’t exhibit digestive symptoms, yet still have a gut imbalance. A malfunctioning GPS can have far-reaching health consequences. For example, many mood disorders, like depression and anxiety, are closely linked to gut health. Rheumatoid arthritis—how much further from the gut could you get?—is also known to be associated with gut imbalances. The list goes on and on. Read about it in my new book, The Road to Perfect Health, available exclusively through my PBS special of the same title. (Check your local PBS listings for show times.)
So, how does your GPS malfunction? Well, there are a number of ways. I’ll highlight some here:
Exposure to chemicals
- Certain medications (like antibiotics and acid-suppressing medications)
- Over processed and refined foods (I call them Dead Foods)
- Low stomach acid
In today’s world, it can be hard to avoid some of these triggers. That’s why it’s best to balance your gut with beneficial probiotic bacteria to get your GPS up and running. As I say: Balance your gut, heal your body.
