The objective principles of shiology are mainly reflected in three fields： food acquisition， eaters' health and shiance order. Most of the objective principles in the field of food acquisition have been revealed by Agronomy and Foodstuff Science. This paper mainly focuses on ten principles in the field of eaters' health and shiance order. Among them， the shiology principles in the field of eaters ' health include the principle of "body is transformed from food”， “different people eat differently"， "eating can cause disease"， "eating can cure disease" and " aesthetics of five senses". The principles of shiology in shiance order include "shiance breeds civilization"， "shiance triangle"， "shiance priority"， "shiance behavior follows food matrix and food transformation"， and "shiance order is the basis of human social order". In addition， there are also five lemmas that extend from the above principles. The ten principles are the core content of the shiology knowledge system， which play an important role in the objective principles revealed by human beings and constitute the basic principles of human civilization. Compared with the scientific principles of mathematics， physics， chemistry and economics， the principles of shiology have three characteristics： popularity， practicability and survivability. The principles of shiology in the field of eaters’ health are all around us， and everyone can understand and master them. Using the principles of shiology can improve the healthy life span of 8 billion people. The principles of shiology in the field of shiance order is an important tool of social governance， which can reduce human social conflicts， reduce social involution， improve overall efficiency of social operation， and maintain the sustainable development of human beings.
