Scientific Research

The number of scientific studies published on the microbiota has increased exponentially in recent years. Once considered a necessary evil because they’re nearly impossible to eradicate, the bacteria that live with us form a unique ecosystem in each human being. We live in symbiosis with the bacteria. The intestinal bacteria live in all the internal folds in different places depending on the environmental niche that they need to live. They settle in one place and live off the foods we ingest.

The microbiota changes according to the ecosystem of the location in the digestive system depending on the availability of foods present (nourishment at different stages of digestion), the secretions of the organs, the pH level, and the oxygen content.

The stomach and the small intestine alone contain 105 colony-forming units (CFUs) per milliliter of anaerobic bacteria (living without the presence of oxygen). These bacteria are responsible for much of the absorption of the nutrients ingested by the human body. On average, 66-95% of the protein and fat we eat are absorbed before entering the large intestine. In addition, sugars such as sucrose, lactose, and starch are digested and absorbed by the small intestine before reaching the colon, while more complex carbohydrates are exclusively broken down and fermented by the bacteria colony present there.

Probiotic bacteria operate on 3 different levels:

  • Interference with the growth of pathogenic bacteria in the intestines;
  • Strengthening of the epithelial barrier and the mucosal immunity, as well as production of mucous in the lumen;
  • Effect on the immune system as well as other organs such as the liver.

This ecosystem is delicate and can quickly become disordered if the diet deteriorates, while taking antibiotics, or during a harmful bacterial contamination.
