In traditional Chinese food culture, people have always pursued an idea that heaven, people and food are closely linked together. Food is not a good with single function and has never been separated from social relations. It is not only the foundation on which ancient emperors founded their state and kept it stable, but also an important carrier of rank order in society. However, since the advent of the industrialization, humanity's diet and lifestyle have radically changed. The core feature of this transformation is that the relationship between people and food becomes more and more separated. Today, with the worldwide social and cultural transformation, food problems and safety concepts appear to be on their way to becoming vital issues. Although in the West modern food production and management mechanisms seem to give us a reference standard, the Chinese understanding of food and their dietary practices also provide us with a logic of thinking which should not be ignored.
