Do I need to drive bile? How many enzymes are required to properly digest food? The Internet is full of conflicting information on this topic: doctors, healthy lifestyle bloggers and manufacturers of dietary supplements cannot agree among themselves. The famous gastroenterologist and hepatologist Sergei Vyalov wrote this book to dispel the myths and medieval prejudices that he has to face every day when accepting patients. He talks in detail and professionally about the processes taking place in the gallbladder and pancreas, and helps to figure out where bile actually goes and whether there are enough enzymes in the body. The digestive tract is a path, and like any path, it has its own philosophy. Only by understanding it can you become a truly healthy person.
