Your Microbiome May Be Key Factor Determining Your Health and Longevity

Mounting research suggests that your microbiome—colonies of bacteria, viruses, and other microbes living in your gut—may be one of the preeminent factors determining your health and longevity.

Feeding health-promoting gut bacteria with a healthy diet, avoiding hospitals (which are hotbeds for drug-resistant bacteria), and boycotting processed foods and animal foods raised in confined animal feeding operations

(CAFOs)—both of which tend to have an adverse effect on your microbiome—may be keystone strategies for longevity. Beneficial Microbes Prevent Disease

A number of studies have begun to identify specific species of bacteria that appear to have specialized functions and abilities to prevent disease. For example, in one study, DNA analysis of

diseased sections of intestine removed from patients suffering from Crohn’s disease revealed that one particular bacterium, Faecalibacterium prausnitzii, was lower than normal.

While researchers have linked the presence of specific bacteria to various diseases, this finding

suggests certain species may be actively involved in preventing certain disease states. When Faecalibacterium prausnitzii was transferred into mice, it protected them against induced intestinal inflammation, suggesting this

particular species may play an important anti-inflammatory role in the human microbiota. As reported by Scientific American:1 “Each of us harbors a teeming ecosystem of microbes that outnumbers the total number of

cells in the human body by a factor of 10 to one and whose collective genome is at least 150 times larger than our own. In 2012 the National Institutes of Health completed the first phase of the Human

Microbiome Project, a multimillion-dollar effort to catalogue and understand the microbes that inhabit our bodies. The microbiome varies dramatically from one individual to the next and can change quickly over time in a single individual...

[A] burgeoning body of research suggests that the makeup of this complex microbial ecosystem is closely linked with our immune function. Some

researchers now suspect that, aside from protecting us from infection, one of the immune system's jobs is to cultivate, or ‘farm,’ the

friendly microbes that we rely on to keep us healthy.” Specific Microbes with Health-Promoting Functions

One group of microbes that appear important for maintaining healthy immune function is the clostridial group of microbes—ironically enough, this group is related to Clostridium difficile, which can cause severe and life-threatening intestinal infections.

But whereas C. difficile prompts chronic inflammation, the clostridial clusters help maintain a healthy and well-functioning gut barrier, preventing inflammatory agents from entering your bloodstream.

The featured research suggests that while certain genetic factors can predispose you to inflammatory bowel diseases like Crohn’s, it’s actually the loss of anti-inflammatory microbes that ultimately allow the disease to blossom. As

noted by Scientific American:2 “[A]lthough... other good bacteria besides F. prausnitzii exist, this similarity hinted at a

potential one-size-fits-all remedy for Crohn's and possibly other inflammatory disorders: restoration of peacekeeping microbes...

The tremendous microbial variation now evident among people has forced scientists to rethink how these communities work. Whereas a few years ago they imagined a core set of human-adapted microbes common to us all, they are

now more likely to discuss core functions—specific jobs fulfilled by any number of microbes.” Inflammatory bowel diseases are not the only health problems affected alterations in your microbiome. Other research has found that onset

of type 1 diabetes (an autoimmune disease) in young children tends to be preceded by a change in gut bacteria. Previous research has also found that certain microbes can help prevent type 1 diabetes,

suggesting your gut flora may indeed be an epigenetic factor that plays a significant role in this condition. Research also suggests there’s a connection between certain types of bacteria and body fat

that produces a heightened inflammatory response that contributes to the metabolic dysfunction associated with type 2 diabetes.

In addition, preliminary research3 presented in 2010 revealed that transplanting fecal matter from healthy thin people into obese people with

metabolic syndrome led to an improvement in insulin sensitivity, again suggesting that such conditions can be effectively addressed by correcting the microbial composition of your gut. Antibiotic Overuse Has Fueled More Deadly

Infections Just as some bacteria help prevent disease, others promote it. One such bacterium is Clostridium difficile,4 the prevalence of which has steadily risen as a result of massive antibiotic

overuse, especially in farm animals. According to the latest statistics released by the Centers for Disease Control and Prevention (CDC), half a million Americans were infected with Clostridium difficile in 2011, and 29,000 of

them died within a month of diagnosis.5,6 ,7 Besides the human death toll, fighting C. difficile costs hospitals a staggering $4.8 billion per year.8 Hospitals are the number one location where

you’re apt to contract this type of infection, but the CDC also notes that many appear to have contracted it during visits to doctor’s and dental offices.9 Nursing homes are also hotbeds for this

hard-to-treat infection. As reported by Reuters:10

“The study11 by the US Centers for Disease Control and Prevention focused on the Clostridium difficile bacterium, which can cause deadly diarrhea. The findings... highlight how overprescription of antibiotics has fueled a rise in bacteria that are resistant to treatment.

People who take antibiotics are most at risk of acquiring C. difficile because these medications also wipe out ‘good’ bacteria that protect a healthy person against the infection.

‘Antibiotics are clearly driving this whole problem,’ Clifford McDonald, CDC senior advisor for science and integrity, said... One in every three infections occurred in patients 65 and older, the study found, with more than 100,000 C. difficile cases found in US nursing homes.”

Fecal Transplants Found Effective Against C. Difficile Infections

One novel treatment that has been shown to be quite effective against C. difficile infections is the fecal transplant.12 Fecal microbiota transplant (FMT) is a relatively simple procedure that

involves taking feces from a healthy donor and transferring it to the patient during a colonoscopy.

The patient basically receives a transplanted population of healthy flora that can go to work correcting any number of gastrointestinal problems, including C. difficile infection.

According to Dr. Mark Mellow, medical director of the Digestive Health Center at Integris Baptist Medical Center in Oklahoma City, fecal transplants lead to rapid resolution of symptoms in 98 percent of patients with Clostridium difficile who have not responded to other treatments.

While I believe fecal transplantation can be lifesaving in some circumstances, I want to make it clear that you will likely never have to resort to receiving donated feces if you address your gut health on a daily basis—by avoiding factors that

kill off your beneficial gut bacteria, and continuously “reseeding” your gut through a healthy diet and regular use of fermented vegetables. Also, any time you take an antibiotic, it is important to take probiotics and/or fermented vegetables to repopulate the beneficial

bacteria in your gut that are killed by the antibiotic, right along with the pathogenic bacteria. If you don’t, you’re leaving the door wide open for further health problems.

Beware of the Risks of Hospital-Acquired Infections

Hospitals are notorious hotbeds for drug-resistant disease, and hospital-acquired infections now affect one in 25 patients! Some of these infections are resistant to antibiotics, which is why avoiding hospitals, barring an acute, life-

threatening condition, is good advice. You could enter with a minor ailment only to come out with one that is much worse... In an effort to rein in some of these hospital-acquired drug-resistant infections, the US

government is now finalizing new cleaning protocols for duodenoscopes13,14—camera-equipped flexible tubes that are threaded through your mouth, down your throat, through your stomach into the top of your small intestine. These reusable medical instruments have been

implicated in a number of hospital-acquired drug-resistant outbreaks. In the latest outbreak, two of the seven patients affected died. The family members of one of them recently spoke out,15 chastising the hospital for not disclosing the risks of contracting such lethal infections upon

admission. According to Dr. John Allen, president of the American Gastroenterological Association:16

"This problem has been known since at least 1987. It certainly is disturbing that a fundamental design issue with these scopes

would cause problems for this long." By Dr. Mercola
