Role and benefits of the gut microbiota
We have coexisted with our microbiota since the dawn of time. Or is it the other way around?
If it is unbalanced or not diverse enough, our health immediately pays the price: inflammation, weight gain, weakened immunity, digestive and sleep disorders, and even anxiety…
In the body, there are different microbiotas : on the skin, in the mouth, in the vagina, in the lungs… The gut microbiota is the most ‘populated’ of them.
More and more studies highlight this collection of microorganisms (bacteria, yeasts, fungi) that populate our intestines, also called our second brain.
According to INSERM, there would be nearly 160 species of bacteria, for an average of 10 trillion microorganisms in adults.

The guest: Martine Cotinat
To discuss our friend the microbiota, today we are talking with a passionate and engaging gastroenterologist, Martine Cotinat, who has just published a short and very interesting book on the subject, “I Rebalance My Microbiota”.
Published by Thierry Souccar, it offers a 4-week program to heal the body from the inside.
Martine Cotinat is not just a doctor. She holds degrees in nutrition, micro-nutrition, and phyto-aromatherapy. She is the author of numerous books, a speaker, and a nutrition educator.
Her current passion is permaculture, and so I refer her to the eleventh episode of our podcast, on permaculture cooking (the eleventh episode of our podcast, on permaculture cooking), or how to adapt the principles of permaculture in the kitchen.
