More evidence to support the effectiveness of Soil Based probiotics.



Soil based bacterial spores offer the advantage of higher survival rate during the acidic stomach passage of the carnivore.

As scientists continue to map the human microbiome, they have begun to delve deeper into the animal microbiome, and they are getting a picture of the difference between normal and abnormal.

Proper microbe/microbiome balance is vital to healthy immune function, providing appropriate protection against potential infections and playing a critical role in the digestion and absorption of food and nutrients. The interaction of multiple strains of bacteria is an essential element in health and well-being.

Researchers are now finding that changes in gut bacteria may even affect the brain and personality. In fact, in studying Germ-free mice, they have found the mice to be dramatically more anxious and hyperactive than their counterparts with a normal microbiome. These changes have also been associated with neurochemical changes in the mouse brain.

Evidence also supports the concept that microbiota balance can have a large impact on healthy metabolic processes. This delicate balance has a definite impact on nutrient acquisition and overall energy regulation and balance. Plentiful research has pointed to the impact of Firmicutes and Bacteroidetes balance on fat mass and obesity, and as fat mass increases so does the release of powerful signaling molecules called cytokines, many of which impact inflammatory processes. Appropriate signaling is essential to maintaining the healthy metabolic nature of the body and, when problematic, could represent an initial stage in the development of metabolic syndrome.

This article and the few references I will list, represent only a few of the many studies examining the impact of gut microbiota balance and the connection between the health of vital body systems such as:

  • The brain
  • Energy homeostasis
  • Complex signaling molecules such as cytokines and adipokines

This is all so exciting!  A definite paradigm shift is underway!

Increasing numbers of farmers are now focusing on sustainable agriculture. They are working at rebuilding the soil (the terrain) with macronutrient fertilizers and their animal manures with the ultimate goal of re-creating the rich “Paleolithic” terrestrial environment in which to grow grass, hay and other crops.

More and more consumers are paying more money and seeking out whole, natural, RAW foods that are nutritionally dense. They are beginning to shun genetically engineered food products and processed foods for themselves and finally, their pets too! More and more of us want the most assurance possible that not just our own food but what we are feeding our companion animals is safe and truly nutritious.

Along with this shift in dietary practices for pets and people comes a shift towards ancestral health practices and species-specific nutrition. One of these practices of course includes increased exposure to the beneficial microbiota both man and animal have been co-existing with for millennia prior to recent times – soil based organisms.  This means that we are turning to soil-based bacteria as a naturally resilient source of healthy probiotic bacteria, while research on SBO probiotics is backing up this wonderful shift.

Lactobacillus, acidophilus and bifidobacteria, the bacterial species typically found in traditional probiotics that have been cultured on diary or plants, simply do NOT have the naturally protective shell inherent to all spore-forming bacteria, so they cannot withstand gastric acids, especially the highly acidic stomach acid of the carnivore. While giving these types of bacteria to our carnivore companions may still have some benefits we are not yet aware of, unfortunately scientific studies show that very few, if any of these organisms ever even reach the lower intestine, even in humans.

Scientific study has demonstrated for example; that yogurt or probiotics grown/cultured in dairy products or plants, just can’t measure up to the hardiness of spore-forming probiotic bacteria. A recent study found that yogurt or dairy grown products have only subtle effects at best on gut bacteria.

The study involved seven pairs of identical twins. One in each pair ate twice-daily servings of yogurt containing five strains of lactic-acid bacteria. The research team performed DNA sequencing on the bacteria in the twins’ stool samples. They found that the yogurt bacteria did not take up residence in the young women’s guts and there was no evidence the bacteria became part of the microbial community at all, in the intestines. The researchers concluded that the yogurt, heavily fortified with “billions of lactic acid probiotic bacteria”, had no effect on the women’s health.   It there was no microbes reaching or taking hold in human guts, it only goes to show that yogurt or dairy microbes are not becoming part of the carnivore microbial community at all!

Soil-based microbial strains have proved to be necessary in breaking down gut matter putrefaction and destroying un-welcome pathogens. This is critically necessary to allow successful re-colonization of the gut, which is desperately needed in most pets and even people today, due to the use of antibiotics and other chemical based medications.

Soil-Based Probiotics: A Natural Advantage

SBO probiotics have a simple, natural advantage. “Bacterial spores offer the advantage of a higher survival rate during the acidic stomach passage and better stability during the processing and storage of the food product,” writes researcher Johannes Bader, from the Technische Universitat Berlin.

You may have seen and/or read on social media, all the big hype on how we should be supplementing our dogs with fermented foods – they are after all, touted as being valuable in re-populating and healing the human gut so surely they will do the same for our carnivore companions, right?   No,not really… while eating fermented foods can be a good thing for supplementing or maintaining gut flora for humans/omnivores, the downside is that our carnivore companions lack the digestive enzymes to completely break down and digest fermented vegetables and/or fermented dairy products.  The argument that wild carnivores eat the contents of the stomach and intestines, simply does not hold up against the fact that the contents of wild prey animals stomachs/intentines – deer, rabbit, etc. do not contain “vegetables” but instead, wild grasses and herbs. Another fact that many raw feeders and holistic veterinarians don’t want to talk about is that in most cases, especially in the case of prey animals larger than a rabbit; it has been observed that the carnivore actually violently shakes out the contents of the intestines of the prey animal prior to eating the intestines themselves.

So again, while fermented foods can be potent and somewhat helpful in humans, they simply do not contain the correct type nor the therapeutic strength of probiotics necessary to destroy pathogenic bacteria, viruses and fungi that have taken up residence within the carnivore intestines, especially in the intestines that have been exposed to antibiotics, chemical wormers, processed, low nutritional value foods and vaccines . These things have destroyed the majority of the “friendly” or good microbes that should naturally reside there.

Also, please know that fermented foods simply are not strong enough by themselves to destroy the dominating pathogens in the gut of an animal or a person suffering from autoimmune disease, leaky gut, etc. They do not contain the strains necessary to re-establish a beneficial balance of microbes and heal/seal the gut wall that is leaking toxins into the bloodstream. Unlike most probiotic supplements, made from fragile, lactic-acid based organisms, SBOs are naturally hardy and will survive its journey to the gut without being destroyed or weakned by the carnivore’s acidic stomach acid/PH.

*A consultation is highly recommended before any preventative or healing program is started. A consultation includes a personalized diet and holistic program suggestions that are custom-tailored to your own dog’s individual and personal needs. While I continue to provide educational articles and information for you here, most of these are general in nature. Therefore, I encourage you to set up an appointment with me to tailor a program specifically for your pet’s needs.
