The microbiota, the ally of my immunity

The different microbiota are the new stars in cosmetics and health. This jungle of billions of bacteria, whose functioning we are only now beginning to understand, is a precious ally against many diseases. Among these champions of immunity, one stands out: the intestinal microbiota. It must be said that by itself it concentrates no less than 60% * of our immune cells. A real shield that is essential to maintain.

The immune system plays an important role in our good health, it keeps diseases at bay, as explained by Dr Cyrille Hoarau, clinical immunologist at the CHRU de Tours and member of the editorial board of “La Revue des Microbiotes”: “From a On the other hand, the immune system has the ability to recognize and destroy pathogenic and cancerous cells. On the other hand, it does immune tolerance, that is, it tolerates the good bacteria that we need. To ensure its protective function, the immune system must be stimulated throughout life. And the microbiota, especially the intestinal microbiota, which contains most of the immune cells, plays this role of booster and regulator. “We know that when the immune system is stimulated, we catch fewer infections. This is why we need the intestinal microbiota which will allow this training. Without it, no effective immune system ”continues the immunologist.

The balance of the intestinal microbiota is influenced by many environmental, therapeutic and food factors. It is known that the urban or rural environment causes great differences in the composition of the intestinal microbiota. But changing places of life is not given to everyone. It is undoubtedly easier to influence your microbiota by practicing regular physical activity. We can also balance it by taking care of his diet, by focusing in particular on the fibers found in legumes (lentils, chickpeas, dried beans, etc.), cereal products (brown rice, wholemeal bread, rye, etc. oats), but also in figs, prunes, wheat germ, artichoke, bananas, almonds …

Pre and probiotics also help regulate the microbiota and strengthen immunity. Probiotics are found in fermented foods like yogurt, kefir, sauerkraut, miso, pickles, in some types of cheese. It is also possible to take it in the form of food supplements. In this case, care is taken to choose the right strains according to your problem. We focus on lactobacilli and bifidobacteria, the most immunostimulating families of probiotic strains.

Studies have shown that Covid-19, like other viruses, changes the composition of the intestinal flora. This could exacerbate the disease by disrupting the responses of the immune system. In addition, in the event of a long COVID, a less efficient microbiota could impact the persistence of symptoms.

To guard against infections and other pathologies, we are working to make our body a haven of peace conducive to the proliferation of good bacteria!
