Something is constantly happening in our digestive system: gastric juice breaks down food, enzymes help the lunch eaten to be absorbed, bacteria neutralize their harmful subspecies. If the digestive mechanism works like a clock, then we feel good, but the slightest disruption in this well-established process immediately spoils the mood and can even lead to a serious illness. The book “Digestion. How are you and him? is dedicated to one of the most important systems of the human body, where the path that food takes when entering the body is examined in great detail. Thanks to it, you will learn what makes food bitter or salty, why children like sweets so much, how the microbiome works, why we need beneficial bacteria, and also learn 10 rules for a healthy intestine.
