Probiotics are lactic acid bacteria and bifidobacteria. They survive the devastating effect of stomach acid, bile acids and digestive enzymes, and exert a beneficial effect on the small intestine, playing a very important role. Lactobacilli are found in the small intestine, while bifidobacteria are found in the large colon.
Probiotics are food supplements containing bacteria beneficial to the human organism. In the food industry, lactic acid bacteria are often used, as they are able to convert sugars, including lactose, as well as other carbohydrates, into lactic acid. This gives dishes a characteristic sour taste, found in yoghurts. Yogurt reduces the pH, inhibiting the growth of harmful micro-organisms and helping to prevent digestive infections.
True partners in our health, probiotics are defined as live ingested micro-organisms (bacteria or yeast).
Probiotics are also particularly indicated when taking antibiotics or when medication disrupts flora and transit.
Probiotics are living micro-organisms which, when consumed in adequate quantities, produce a health benefit for the host. The micro-organisms of the intestinal flora make up the intestinal microbiota.
A microbiota is the set of microorganisms inhabiting a microbiome, i.e. a well-defined living environment. The intestinal microbiota is made up of 100,000 billion living micro-organisms.
In all individuals, there are 3 major bacterial phyla (out of 55 in existence) representing 80 to 90% of the fecal bacterial species common to the human genus: Firmicutes, Bacteroidetes, Actinobacteria, and one of lesser population importance: Proteobacteria. Within these major kingdoms, 6 genera are found in dominance: Eubacterium, Lactobacillus, Enterococcus, Clostridium, Bacteroides, Bifidobacterium.
The balance of the intestinal microbiota appears to be involved in a wide range of pathologies. The role of the microbiota is implicated in neurodegenerative diseases, among others.
Changes in the intestinal microbiota induced by an ultra-processed Western diet favor the development of neurodegenerative diseases. Alterations in the microbiota have been observed in Parkinson's disease, which could be a biomarker in the future: a decrease in Prevotellaceae, and conversely an increase in Enterobacteriaceae, which is associated with more severe postural instability; an increase in Lactobacillus, Bifidobacterium, Verrucomicrobiaceae and Akkermansia, and a decrease in Faecalibacterium spp. have been observed, Coprococcus spp, Blautia spp, revotella spp. and Prevotellaceae.
In Parkinson's disease, for example, intestinal dysbiosis is observed. Similarly, a change in the microbiota is observed in Alzheimer's disease.
The use of probiotics leads to a marked improvement inirritable bowel symptoms (or functional colopathy).
The mechanism of action is thought to result from immunoregulation between pro- and anti-inflammatory cytokines. Some probiotics elaborate antibacterial molecules (bacteriocins), others increase the production of innate immune molecules in the mucosal barrier (mucins, defensins), or promote adaptive immune responses (secretory immunoglobulin A, regulatory T lymphocytes, interleukin-10), while some probiotics activate receptors in the enteric nervous system, helping to relieve visceral pain.
Zonulin, a protein synthesized by the intestinal mucosa, is the physiological modulator of strong intercellular junctions, involved in intestinal hyperpermeability (permeable bowel syndrome), incriminated in various pathologies (dysbiosis, bacteremia, inflammation, autoimmunity, cancer).
Gluten's gliadin induces increased intestinal permeability to macromolecules. Certain strains are anti-inflammatory: Lactococcus lactis, Lactobacillus casei, Lactobacillus plantarum, Bifidobacterium infantis, Faecalibacterium prausnitzii.
Combining the effects of medicinal plant extracts oressential oils with probiotics may represent a new approach due to their complementary antimicrobial effects.
