I want you to imagine that the surface of your intestines is a battlefield. There are two armies waging war – the good bacteria (probiotics) and the bad bacteria (pathogens). Obviously, we want the good bacteria to win this battle because they help us in a multitude of ways like improving digestion and nutrient absorption, reducing inflammation, boosting our immune system, and protecting us from harmful microbes.1,2 The pathogens on the other hand contribute to inflammation in the intestines and throughout the body, poor digestion, leaky gut, ulcers, malnutrition, and a weakened immune system.
We simply give them the food they need to thrive so they can crowd out the bad guys. Luckily, probiotic bacteria and pathogens eat very different types of food and they respond quickly to the food they are given. In fact, you can change the balance of probiotics vs. pathogens in your intestines in as little as 24 hours simply by altering the type of food you eat.3
Prebiotic Fiber! The term “PREbiotic” refers to the food that “PRObiotics” eat - which is primarily dietary fiber found in plant-based foods. One of the reasons high fiber foods like fruits and vegetables are so healthy for us is that they provide prebiotic fiber for our healthy probiotic bacteria to eat.4 When the probiotics are fed well, they multiply quickly and crowd out the pathogenic bacteria that make us sick. The bad pathogenic bacteria tend to prefer simple sugars and other ingredients we tend to find in junk foods.
If you are like 97% of Americans then, no – you are not getting enough fiber. According to recent national surveys, less than 3% of the population meets their recommended daily fiber intake.5 Generally, you want to aim for at least 13 grams of fiber for every 1,000 calories you consume, so a 2,000 calorie diet would require at least 26 grams of fiber. Despite abundant knowledge about the benefits of fiber and fortification of food products, most of us are still falling short. While it would be great to get all of your daily fiber from your diet, we know that this is an ideal situation that is not possible for some people, so a supplement may be required.
Think back to our image of a battlefield: consuming probiotic foods or supplements would be like sending more soldiers into the fight to replace those that have been lost. It can help to get the numbers up in a hurry, but it can be expensive and without the proper nourishment they will continuously need to be replaced. Using a Prebiotic Fiber supplement, however, is like sending in supplies to support and strengthen the troops that are already there fighting. Essentially, using prebiotics allows you to grow and maintain a strong “army” of probiotics in your intestines, always on standby to take out any invading pathogens. Prebiotics make probiotics happy - and happy probiotics reproduce - so using a prebiotic also increases the size of your "army."
You should consider the cost difference between probiotics and prebiotics. Probiotic foods and supplements depend on having significant numbers (colony forming units, or CFU’s) of living bacteria that can make it through the digestive processes in the stomach and small intestines, all the way to the large intestine. Most of the probiotic supplements that have meaningful amounts of living bacteria in them are quite expensive with short shelf lives and often require refrigeration.
Probiotic foods like yogurt and naturally fermented foods (sauerkraut, kefir, pickles, kimchi) tend to provide such small amounts of the beneficial bacteria that you would need to eat dozens of servings to make a significant impact – this is not necessarily an efficient strategy for most people. On the other hand, Prebiotic Fiber does not contain or need to contain any living bacteria in the product itself to be effective, so they cost less, last longer, and can better tolerate being incorporated into foods when compared to probiotics.
Now, let’s say you were just on a prescription antibiotic because you were sick. There’s a good chance that the antibiotic altered the balance of good and bad bacteria in your intestines by killing off both good and bad bacteria. This is one reason why antibiotics can cause diarrhea for a lot of people.6 Prebiotics can certainly help the good bacteria recover and should be used, but this might also be an appropriate time to consider “sending in more troops” by adding a high-quality probiotic to get your numbers back up as quickly as possible.6 But for the long-term maintenance of that healthy probiotic bacteria you will need to be feeding them with the Prebiotic Fiber that sustains them. At the end of the day, it is more economical to maintain your healthy gut bacteria with a prebiotic and save the expensive probiotics for specific situations like using antibiotics.
Not all fibers are the same when it comes to supporting healthy gut bacteria.
Soluble fiber provides a better food source for bacteria than insoluble fiber, like psyllium husk, which is used more for its bulk-forming properties to promote bowel movements.7 Supplements with insoluble fiber generally don’t taste very good and have texture issues, so they tend to be incorporated into products with a lot of added sugars and flavors. In fact, many contain more sugar than fiber, which would do more to support the pathogens than the probiotics.
Products that use polyethelyne glycol, such as Miralax®, are actually osmotic laxatives and do not contain fiber at all. People sometimes assume that this type of product contains fiber because they are usually found near fiber supplements in stores and pharmacies - but this is not the case.
Some prebiotics like inulin (found in chicory) and fructooligosaccharides (FOS) do not tolerate heat or acidity very well and break down into simple sugars when they are incorporated in foods or exposed to stomach acid.8 They also tend to be digested very quickly by intestinal bacteria, meaning they can cause gas and bloating with servings as low as 3 grams.9,10
In comparison, the non-GMO digestion-resistant maltodextrin used in Pinnaclife’s Prebiotic Fiber supplement is heat and acid stable and gets digested slowly by the bacteria so you can consume more than 11 grams of fiber per serving without the gas and bloating.11,10 It is flavorless soluble fiber without any added sugars, sweeteners or flavorings so it can be easily and unnoticeably added into your favorite food and drinks – you can even bake with it!
Basically any food or drink that can be stirred can have Pinnaclife Prebiotic Fiber added to it to boost the fiber content and support healthy probiotic bacteria without altering the flavor, appearance, or texture. Plus you get the added antioxidant support from Olivamine 10 Max!
