Probiotics Destroy Toxic Chemicals in Our Gut for Us
By Sayer Ji
It is an awesome fact of nature that we have trillions of organisms within our body – containing completely foreign DNA – some of which break down toxic chemicals that we humans have created to kill other things, but are now killing us, e.g., pesticides. Who are these strange helpers?
Wait. Aren’t bacteria supposed to harm us? Aren’t they the enemy in the endless war against infection?
Well, when our immunity fails, some can grow out of bounds opportunistically. But they respond to the environment within which they are raised, not unlike most other creatures.
• Provide organic, wholesome vegetables, for instance, and you have a hotbed of positive activity in your gut.
• Provide sugar, processed foods and an increasing burden of chemicals and it can get ugly in there!
Also, believe it or not, ancient bacteria teamed up with our cellular ancestors eons ago to produce the energy-producing organelles within our cells called mitochondria. [See “Probiotics and Mitochondria: Bacteria are Not Other.”]
So, are we really that different from bacteria? No, on some level, we ARE bacteria, spurring some researchers to describe us as "meta-organisms," composed as we are of many different living systems working symbiotically.
Let’s look at some of the amazing feats of these friendly bacteria….
1. Bisphenol A Toxicity: Absorption/Excretion
Bisphenol A (BPA) is an increasingly omnipresent petrochemical derivative with endocrine-disrupting properties (i.e., it messes up your hormones!) and is found in thermal printer receipts, all world paper currency, plastics, and many other consumer goods.(1) Sadly, it is not a matter of whether or not you will be exposed, but to what degree.
Enter the probiotics Bifodobacterium breve and Lactobacillus casei. In supplemented rats exposed to BPA in their diet, blood concentrations of BPA dropped significantly and it was excreted in their feces 2.4 times more readily than the non-supplemented control group. The researchers concluded that the probiotics "…reduced the intestinal absorption by facilitating the excretion of BPA, and that these probiotics may suppress the adverse effects of BPA on human health."
2. Bisphenol A Toxicity: Degradation
Novel, bisphenol A-degrading bacterial strains were isolated from the traditional Korean fermented cabbage dish known as kimchi.(2) Three isolates of Bacillus pumilus [commonly found in soil and salt tolerant] were shown capable of degrading BPA.
The researchers reported that these food-derived bacteria would make efficient and safer systems for the removal of BPA. Logically, the consumption of kimchi (or the probiotics extracted from kimchi) would enable a human’s gastrointestinal tract to break down this harmful chemical, as well. [Kimchi, like traditional unrefrigerated Western saurkraut, is made in brine without vinegar; in which the action of lactobacilli, also salt tolerant and plentiful on the roots & leaves of vegetables growing in or near the soil, creates lactic acid which acts as a preservative while promoting the growth of healthy flora.]
3. Insecticide Toxicity
Here comes kimchi to the rescue again! In 2009, the Journal of Agricultural and Food Chemistry revealed that the rather nasty insecticide chlorpyrifos (CP), which has been linked to neurological effects, developmental disorders and autoimmune disorders, may be no match for the bacteria that make possible kimchi fermentation.(3)
The researchers found the bacteria in kimchi turned CP into lunch (a source of carbon and phosphorous) and degraded it rapidly until day 3 (83.3% gone!) and degraded it completely by day 9!

The superheroes in this story were identified as: Lactobacillus brevis WCP902, Lactobacillus plantarum WCP931, and Lactobacillus sakei WCP904. But then things got even more amazing…..
These toxin-muching superheroes were found to degrade four other insecticides:
1. Coumaphos – Insecticide
If you think the chemical-munching and degrading abilities of probiotics are amazing…
Then consider that probiotics perform thousands of vital functions within our body, and have been clinically researched to prevent and/or reduce the symptoms of close to 200 different diseases. You can view the first-hand research on the benefits of probiotics on GreenMedInfo.com's research page dedicated to the topic. [An archive of abstracts on the benefits of more than 20 types of probiotics.]
Healthy Bacteria Depend on the Health of the Soil, and the Health of the Soil Depends on YOU
When it comes to good bacteria, it is important to point out that humans do not live within a vacuum. The quality of the bacteria in our gut reflects the quality of the food we eat, which ultimately depends on the quality of the soil.
If you grow your vegetables in raw human sewage (from unhealthy folks), or factory-farmed animal waste, already preloaded with antibiotic resistant bacteria and chemicals, there is little hope that you will receive sufficient beneficial bacteria from that food.
What is more likely is that you will be exposed to highly pathogenic antibiotic resistant bacteria which have already survived decades worth of chemical and antibiotic exposure within the human gastrointestinal tract, or loads of zoological antibiotics used on the Concentrated Animal Feeding Operation (CAFO), almost guaranteeing your own microflora will be continually challenged with unhealthy, disease-promoting strains of bacteria.
This is one of the most disturbing and unspoken aspects of conventionally produced food, but there are others: gamma irradiation, bacteriophage-sprays, etc.
Moreover, new research indicates that our increasingly GMO-based global food production system which depends so heavily on broad-spectrum biocides like the active ingredient in Roundup "weedkiller," namely, glyphosate, is destroying the fertility of the soil.
Essential, and culturally ancient, food-starter bacteria – as used in fermented foods like cheese and yogurt – are disappearing in certain regions of the world. The soils have become saturated with herbicides that are destroying the microbial biodiverisity, without which many of the foods that we consume would not be possible.
When that lifeline to health which comes from the soil is cut off, our own health is compromised – perhaps irreversibly.
What does this mean? Planetary health and human health are no longer separable – truth is, they never were. We need to move beyond the concept that we can hermetically seal ourselves off from the ecological destruction and mass poisoning occurring all around us by only consuming "organic."
If things continue at the pace they are going, the word "organic" will have no meaning whatsoever – other than marketing spin. The case of perchlorate accumulation in organic food makes this problem blatantly clear. In other words, unless we become activists on this issue, we will lose everything.
I believe one good place to start is to support campaigns such as the California Right To Know Campaign which will place Right to Know Genetically Engineered Food Act on the Ballot for Nov. 6th.
