The gut plays a central role in our physical and mental wellbeing, influencing our body shape through the gut microbiota, formerly known as the gut flora. The composition of this microbiota changes according to our lifestyle, diet, physical activity, and eating habits. These changes can lead to beneficial effects such as the regulation of weight, cholesterol, blood sugar levels, and immunity, or to negative consequences such as skin problems, excess weight, joint pain, as well as behavioural or mood disorders, depending on various factors.
Often referred to as the second brain, the gut maintains constant communication with the brain. Scientific research has revealed that, of every 10 messages exchanged between the two, 9 originate in the gut and only one in the brain. The gut’s neural system is a tangible entity, generating around twenty endogenous hormones that no other organ in the body produces.
