What features of human nutrition affect the structure of his digestive system?

The food we eat affects the structure of the digestive system. This applies to all animals. The stomach secretes those enzymes and acids that are capable of digesting and breaking down food. We calmly digest plant and animal food, as well as meat. But there is some controversy that a person cannot eat meat. To understand that our digestive system is tailored for certain foods, you need to look at what other organisms eat and compare with us. We cannot eat bark, wood and some herbs, although other species can.
