In this dossier, you’ll discover the importance of Hippocrates’ principles and their relevance to modern medicine. Hippocrates, often called the father of Western medicine, put forward fundamental precepts such as the importance of diet as the first medicine, regular physical exercise and the principle of “first do no harm”. He also stressed that all disease begins in the gut, a notion that is proving even more relevant with current discoveries about the intestinal microbiota. The video highlights explanations of how the digestive tract works and its crucial role in overall health. The intestine, from mouth to anus, transforms food into absorbable nutrients and is home to the intestinal microbiota, essential for well-being. Vincent Castronovo explains how to keep the intestinal barrier in good condition to prevent chronic and autoimmune diseases. He stresses the importance of a healthy diet, proper chewing and a healthy lifestyle to preserve the integrity of the intestine and prevent systemic inflammation, which is responsible for many diseases.
