Part Ⅱ The digestive system and diarrhea
The human body is a highly complex self-generator, that is to say, provided it is given the right fuel, it is capable of both curing and warding off disease. The food we eat helps to give us energy. It has a long journey to make before all its goodness has been taken into our body. The food takes up to six hours to be digested in the stomach, depending on the size of the meal. The complete digestive process takes about 24 hours. But sometimes the system can go wrong.
