We recently hosted a guest in our Undoctored Inner Circle weekly Virtual Meetup (via Zoom), noted microbiologist Dr. Raul Cano.
Dr. Cano has had a long career in creating unique findings worldwide of the human microbiome, including sequencing ancient stool from naturally mummified human beings dating back many centuries and obtaining fungal and bacterial types from amber a la Jurassic Park. He even brewed beer from a fungi obtained from the stomach of an ancient bee that was 25-45 million years old.
Amongst a lot of Dr. Canos insightful declarations was one that truly stuck in my mind. In action to a concern regarding the reliability of different gut plants testing techniques, he made the point that microbes inhabiting the human colon (along with upper intestinal, GI, tract) vary inch-by-inch. As we continue through our days, we consume various foods, consume different liquids, experience different feelings, engage in various activities, experience various hormonal modifications, and so on, all of which influence microbial composition of the GI tract. It implies that, by sending a small sample of defecation for analysis, we are only sampling a small snapshot of stool microbial structure however failing to analyze the much broader series of microbes (and metabolites) that might be discovered all throughout the GI system.
For this reason, Dr. Cano, by means of an organization called the BioCollective, uses whole defecation for analysis, instead of little samples. They homogenize (mix) the sample, and after that carry out genetic analyses to specify the microbes present. Dr. Cano and BioCollective creator, Martha Carlin, told me that, by analyzing whole samples, numerous unique observations have actually been made that are extremely different from evidence collected from small stool samples.
The typical adult human colon is roughly 5 feet in length, or 60 inches. It is a virtual record of the previous 24 or more hours: what you ate for breakfast, lunch, supper, treats; how much prebiotic fibers, polysaccharides, polyphenols, and sugars you consumed; how numerous herbs, spices, and other foods with antimicrobial properties you consumed; just how much tension you experienced (recall that the gut-brain axis is bidirectional); how well or for how long you slept; what drugs you took; the quality of the air you breathed (air pollution likewise has microbiome ramifications); age-related and circadian modifications in hormones and other factors. Analyzing entire stool samples is for that reason a minimum of a big action in the right direction of acquiring a more comprehensive viewpoint on bowel plants structure. (Unfortunately, the BioCollective is only carrying out such analyses for research, not for medical functions.).
It implies that, no matter whether you send a stool sample for analysis to GI Map, GI Effects, Viome, Thryve, Vibrants Gut Zoomer, Verisana, or other techniques, all you are going to receive is a small picture of bowel plants composition. Send a different poop sample from the exact same defecation and you are most likely to get various outcomes. Among our Undoctored Inner Circle Members recently sent stool samples, all from the exact same defecation, to four various testing services. Each service reported different outcomes, with some results in direct contradiction of each other.
What to do with such extensively variable, discrepant, and incomplete results? The BioCollective technique of entire stool analysis would be a start of an option, though I understand of no laboratory currently doing this commercially. Another way, though pricey, would be to submit several samples either within a single bowel movement or over numerous bowel motions.
Bottom line: Be cautious with interpretations of bowel flora analyses, as they can just offer a restricted view of what is going on in your GI system, just a picture with limited capability to characterize the entire microbiome. Physiologic steps supplied by such screening services, nevertheless, such as pancreatic elastase or calprotectin levels, are more reliable and bring higher certainty. Well-defined overgrowth of, state, Enterobacteriacea such as Klebsiella or E. coli must be taken seriously.
As we continue through our days, we eat different foods, drink various liquids, experience various emotions, engage in various activities, experience various hormone modifications, etc., all of which influence microbial structure of the GI tract. Dr. Cano and BioCollective creator, Martha Carlin, told me that, by analyzing whole samples, numerous distinct observations have been made that are very different from proof gathered from little stool samples.
