What’s post-biology?

Postbiotics are primarily the byproducts of our intestine microbiota. In different phrases, your physique makes postbiotics after digest prebiotic and probiotic meals.

Examples of postbiotics embrace the short-chain fatty acids butyric acid (or butyrate), acetic acid (or acetate), and propionic acid (or propionate).

These molecules are produced when good probiotic micro organism break down fiber from meals like vegetables and fruit, grains, and legumes.

These postbiotics are vital in your intestine microbiome. Wholesome probiotic micro organism thrive on these short-chain fatty acids in our intestine.

And a few postbiotics may help stave off “unhealthy” micro organism. For instance, probiotic micro organism (akin to Lactococcus lactis) produce particular chemical substances known as micro organism that may block the colonization of pathogens akin to E coli within the gut. This course of is called “colonization resistance”.

Microbial fermentation is the place microorganisms within the intestine break down advanced carbohydrates. Specifically, microbial fermentation in a plant-based (polyphenol-rich) food regimen results in the postbiotic manufacturing of phenylacetic acid. This postbiotic can scale back the expansion of dangerous pathogens within the physique.

One other research discovered low numbers of short-chain fatty acid-producing micro organism in premenopausal breast most cancers sufferers.

A number of cell and animal research have additionally reported that postbiotic butyrate could assist chemotherapy struggle breast most cancers and higher regulate the immune system.

As reported in epidemiological research, a food regimen wealthy in fiber, particularly complete grains, could scale back the danger of colorectal most cancers. That is primarily as a result of a high-fiber food regimen results in the manufacturing of short-chain fatty acids within the colon.
