‘Bacteria in our gut enable us to live. We could not survive without bacteria. … They allow us to digest food, to assimilate the nutrients in our food; and they play a huge role, just beginning to be understood, in our immune functioning and in many other processes in our bodies. All life has evolved from bacteria and no other form of life has lived without bacteria. … Our bacteria perform all sorts of essential functions for us, and because we are continually attacking them effectively with all of these chemicals in our lives, simply replenishing and diversifying these populations has a benefit for us.’ Sandor Katz

Not all of us walk around aware that there is a living, thriving, non-human colony of organisms that resides in our digestive tract. Your large intestine is home to approximately 4 pounds of beneficial bacteria, collectively known as the microbiome. This microbiome consists of thousands of different strains of bacteria, totaling up at around one hundred trillion cells.

In fact, bacterial cells outnumber human cells by a ratio of around 10:1. They provide innumerable functions for us, many of which are probably still unknown, but include digestive, absorptive and assimilation functions. The microbiome influences the immune, endocrine and cardiovascular systems.

Fermented foods are foods that have been through a process of lacto-fermentation in which natural bacteria feed on the sugar and starch in the food creating lactic acid. This process preserves the food, and creates beneficial enzymes, B vitamins, Omega-3 fatty acids, and various strains of probiotics (beneficial bacteria). The proliferation of lactobacilli in fermented foods enhances their digestibility and increases vitamin levels.  These bacteria promote and support the growth and development of those healthy bacteria throughout your intestines. Probiotics are a supplemental form of beneficial bacteria that can be used to bolster the microbiome, balance immunity or to be used for specific conditions.

It turns out that there are a lot of good reasons to consider incorporating probiotic rich foods or a good form of probiotic supplementation into your daily regime, including:

  • Regulation of bowel function, improving both constipation and diarrhea
  • Supporting the breakdown of proteins into free amino acids
  • Aiding the digestion of lactose, improving intolerance
  • Reducing intestinal inflammation, the cornerstone of many digestive disruptions and disorders
  • Reducing gas and associated pain
  • Optimizing intestinal pH, creating an unfriendly environment for pathogenic (unfriendly) bacteria, yeasts and other harmful organisms
  • Short chain fatty acids are a major fuel source for the cells in the gastrointestinal tract and are manufactured by the good bacteria in your microbiome
  • Supporting the manufacturing of B vitamins and vitamin K
  • Changing the structure of certain plant compounds such as flavonoids so they can be optimized by your cells.
  • Preventing and treating antibiotic-associated diarrhea
  • Creating a buffer against food poisoning and the toxins released from bacterial, yeast or parasitic infections.
  • Supplementation with probiotics aids in the treatment of urinary tract infe
