The intestinal microbiome plays a crucial role in protecting the digestive tract and modulating the immune system. Discover how it works and its impact on health.
[...] How to Improve and Care for Your Intestinal Microbiome4 ? - First, we need to adopt a varied and rich diet in plant fibers to promote diversity of our intestinal microorganisms. - A controlled exposure to microorganisms from birth (contact with nature and animals) helps to develop a healthy and balanced microbiome. - Another important aspect of lifestyle is to limit (or eliminate) alcohol consumption and reduce red meat consumption, and above all, learn to manage stress. - Finally, we need to consume probiotics, fermented foods (yogurt, bread, or sauerkraut) that directly provide beneficial bacteria to our microbiome.

[...] It acts on digestive, metabolic, immune, and neurological functions. It has not only a local impact, but also influences the innate and adaptive immune responses of the organism as a whole. Beyond the intestine, the intestinal flora can also modulate systemic immune responses, with beneficial or deleterious effects depending on the pathological context. The intestinal microbiome is capable of preparing the immune system to react effectively against pathogens through the diffusion within the body of substances produced by the bacteria of the microbiome and their metabolism.

[...] In general, bacterial metabolites are responsible : - of modifications of the food bolus, - of anatomical modifications of the digestive tract, - of stimulation of the host's immune system (barrier effect). Source : Hill MJ. (1997) Intestinal flora and endogenous vitamin synthesis. Eur J Cancer Prev. ; 6 Suppl 1:S43-5. Focus on the relationship between the intestinal flora and the immune system The intestinal flora and the immune system have been interacting closely since birth. Their collaboration is essential for the development and maintenance of what is called the "intestinal immune barrier". How? [...]
[...] However, on the other hand, the microbiome, and particularly SFB, can also exacerbate inflammation in arthritis models by exacerbating the production of auto-antibodies. Here's how the intestinal microbiome protects the digestive tract from aggression caused by potentially pathogenic bacteria: the intestinal microbiome helps our body to distinguish between useful bacteria and pathogenic bacteria by producing metabolites and creating a protective barrier. However, since it is the basis of many bodily functions, an imbalance of the microbiome or "dysbiosis" is linked to various diseases. Diseases such as diabetes, obesity, and cardiovascular diseases are associated with imbalances in the intestinal microbiome. [...]
[...] Conclusion In conclusion, our intestinal microbiome is a complex ecosystem. We, the host, and microorganisms are in constant "co-evolution" at the epithelial level. We now understand that the intestinal microbiome plays a major role in our health, particularly in our immune system. However, since it is fragile, solutions exist to preserve and improve our microbiome, such as a diet rich in fiber and the consumption of probiotics. [...]
