What Brings us to the Colon?
Sure, you can just go out and buy prebiotics. In fact, Prebiotin is an excellent prebiotic fiber supplement. But because Jackson GI is all about a nutritionally-aware consumer, here's the "story" before you just up and buy prebiotics to supplement your diet...
The Comfortable Past
Many years ago in medical school, there was not much to teach about the colon. We knew it was filled with bacteria, perhaps 300-400 types. The liquid stool entered it from the small intestine. Water was extracted from the stool so that when it arrived in the rectum, you had, hopefully, a soft, once-a-day stool pattern. It was an uncomplicated process and organ. We spent most of our time studying the diseases of the colon such as irritable bowel syndrome, diverticulosis, Crohn's disease, ulcerative colitis and colon polyps and cancer. The idea that the colon was a quiet health producing organ was totally foreign. The colon, in those days, was simply a receptacle that held the waste the body did not use until it could be evacuated. Pretty simple and pretty wrong.
What We Now Know About Food Fiber
During my years in practice, I was a firm advocate of increasing food fiber in the diet. I was aware of the work of researchers in Africa who discovered that rural Africans who consumed a largely plant based diet with lots of fiber had 2-3 large, soft bowel movements a day. In addition, they seldom had diseases of the colon that are so common in the Western world. A high fiber diet made sense to me and many of my patients were relieved of constipation and simply felt better on such a diet. Further, some epidemiologic studies (including heart disease and cancer) began to show health benefits when fiber was significantly increased in the diet. Still, it seemed that this was the end of the fiber story. Little did I know!
There are many types of fiber that have been discovered in plants, including various types of starches, lignins, cellulose and others. These were of interest to plant chemists, but not to physicians. Then in the 1980s, it was discovered that fiber could broadly be separated into insoluble and soluble types. No fiber is digested by the small intestine. All of it arrives into the colon unchanged. Insoluble fiber does not dissolve in water, is not fermented or broken down by colon bacteria, but does retain lots of water in the colon and so provides a larger, softer stool. Soluble fiber, on the other hand, is broken down and fermented by colon bacteria. We really didn't know too much more about these two types of fiber until the 1990s when better measuring methods were devised. In the last 15 years, the difference between these two fibers, insoluble and soluble, has become increasingly important, especially with the discovery of prebiotic soluble fibers.
Microbiota - The Glorious Cauldron of Colon Bacteria
In the recent past, researchers and physicians have come to understand the makeup of the colon bacteria to a remarkable degree. Microbiologists have been able to isolate and grow some 300-400 different bacteria from the colon, along with some viruses and yeasts - all entirely normal to find in the colon. In the past few years, reaearchers have been able to use complex microprobes to analyze the DNA within all the colon's bacteria, an amazing feat. Still more amazing, it has been found that there are likely over 1,000 different types of bacteria growing in the colon, twice the number previously known. In addition to that, the total number of bacteria in the colon is measured to be many trillions, at least 10 times the number of cells in the entire body. It gives you pause when companies that sell probiotic bacteria products claim to have 5 or 10 billion bacteria in a pill, an incredibly small number compared to what is already in the colon.
Here is a final fact to consider. There is no place in the world, no organ or colon in any other animal or fish where there is such a tightly packed collection of bacteria, as in the human colon. This is normal. So, the question is - why do humans have this incredible collection, this glorious, chaotic, tightly packed mix of bacteria as a normal part of our bodies? The answers are slowly coming in. They are incredibly surprising and exciting to scientists and physicians. The story can be best understood by knowing something about prebiotics.
Prebiotics
 Prebiotics are really the new kid on the block. The term was coined in 1995. A prebiotic is a special type of soluble fiber that is used mostly by the beneficial good bacteria as a fuel. These good bacteria, in turn, produce certain substances that acidify the colon (a very good thing) and serve as a nutrition source for the colon's own cells. Isn't this remarkable? The colon provides a warm, oxygen-free environment for these beneficial bacteria to grow. These bacteria, in turn, manufacture the nutrition source for the colon itself. This is a true symbiotic relationship where both the bacteria and colon depend on each other and promote each others' health. Of course, the body benefits even more as some, rather remarkable health benefits occur when this system is operating maximally.
So what are these prebiotics? The ones with the most science behind them are inulin and oligofructose. Inulin, itself, is remarkable in that it has been around in the plant world for a very long time. It has been found in over 36,000 different plants, so it somehow has been a vital food source for plant-eating animals and humans for a very long time. Interestingly, as our food industries and agriculture have developed, the foods in which we get inulin have become limited.
We now find inulin in: wheat, onions, bananas, garlic, leeks, chicory root, Jerusalem artichokes, wild yam, agava, and jicama.
In the U.S., most people get very little of this valuable fiber, perhaps only 2-3 grams a day on average with 70% of this coming from wheat and 20% from onions. Europeans eat three to five times this amount of inulin containing foods.
A prebiotic:
 1) is not digested by the small intestine
2) is used as fuel, or fermented, by some colon bacteria
3) produces health benefits by objective measurements
According to some leading authorities, only inulin and oligofructose have fulfilled these three criteria and that is why these are the two clinically-proven prebiotic fibers we use. Because we are dedicated to medically-credible supplements, our prebiotic supplement, Prebiotin, uses a special blend of these two proven prebiotic fibers only. Yes, there are also some possible prebiotics coming along such as: galacto oligosaccharide (GOS) - from milk, xylo-oligosaccharide - from wood pulp, isomalto-oligosaccharide (IMO) - from corn and wheat, soybean, and barley food extract. However, these possible prebiotics have not yet met all three above criteria in clinical testing. When (and IF!) they meet these criteria, we will consider adding them to Prebiotin.
So, the proven prebiotics fibers are a relatively new discovery. More than this, they have been found by careful research to provide significant health benefits, not only to the colon but to the body as a whole.

The Colon as a Health Organ
The colon, as a health organ, is an incredible idea. Who would have thought it? Facts, however, have a way of pushing themselves in front of you and, sooner or later, you just have to pay attention. So, here are some facts about what prebiotics do when they are acted on by the good bacteria in the colon. These facts are supported by research. Some of it is hard, meaning there is a lot of support in the research community. Some is soft, where there is early work showing benefits but more is needed. So consider the following benefits for the body when prebiotics, either in food or supplements, are taken in adequate doses.
-Increased probiotic growth. Yes, the probiotics you take need nourished by prebiotics.
-Improved bowel regularity-softer and more regular BM
-Increased absorption of calcium and magnesium throughout the colon
-Increased, stronger bone density. This is particularly true for young teenagers.
-Enhanced immune factors in the colon
-Reduced colon polyp and colon cancer causing factors
-Reduced triglyceride level
-Reduced allergies and asthma, especially in infants and children
-Controlled appetite and reduced weight
-Dramatically increased growth of good protective colon bacteria, bifidobacter and lactobacillus.
-Decreased growth of bad colon bacteria, clostridium and others
-Decreased or cessation of offensive flatus smell
Well, there are other benefits suspected from prebiotics, but you get the picture. There are a lot of healthy things happening when you get adequate prebiotic fiber such as inulin and oligofructose.
The Future of Prebiotics and Colon Health
No one should be rash enough to predict the future. However, it is always fun to close your eyes and think what might be. As a nation, we in the U.S. have reached a bizarre, almost schizophrenic, stage. Our food manufacturers have doused us with calories and high fructose corn syrup. We have an epidemic of obesity, undoubtedly with very poor nutrition. At the same time, Americans are living longer for a variety of reasons. Further, I am impressed that so many younger people seem to be shifting to, what I would judge to be a better-balanced diet with less red meat and increased vegetables and fruits. And further still, I see so many young people, especially girls and young women, who are aggressively taking care of their own health.
So, there are pluses and minuses. In my field of gastroenterology, I would dearly like to see prebiotics assume a role in the dietary management of many colon disorders. There is no downside, aside from excess colon gas if too much is used, and there may be great benefits. Just this past month, a friend with ulcerative colitis told me that since starting prebiotics, his bowels are regular, he feels better, he has reduced his medication and his malodorous flatus (hydrogen sulfide) no longer smells (see Ulcerative Colitis Dietary Therapy). This is one person and one case proves nothing. No one with any colon disorder should make dietary changes without advice from their physician. However, putting this information together has been incredibly stimulating. If, over time, these prebiotics food fibers can make a gradual improvement in the public's health, to say nothing of those with gastrointestinal problems, then my own medical career will have been topped off beyond my dreams.
