The narrative structure of "Yi of Food" is based on the three main ideas summarized in "Diet Therapy Materia medica". It is simple and easy to understand, and is widely accepted by people. The whole work is divided into three layers emotionally. The first layer is to receive understanding and have a preliminary understanding of Diet Therapy Materia Medica. The second layer is to have a deep and clear understanding of the concepts in the book, know the historical status of Diet Therapy Materia Medica and the application and development of Diet Therapy Materia Medica in today's society. The third layer is the respect of Chinese and foreign people for dietotherapy and TCM culture and their hope for the inheritance and development. This kind of narrative structure makes the rhythm of "The Lost of Food" compact, with the beauty of full details, closely related to people's daily life, and can clearly express ideas. The music in "The Lost of Food" is not straightforward, a large section of music is laid out, but the two music of "Chinese Theme Song of Materia Medica" and "A Thousand Miles of Rivers and Mountains" are selected as the main body, integrating music and documentaries, and rising with emotional ups and downs. The paragraph changes. The theme of Materia Medica can be seen from the soundtrack alone, which is closely related to traditional Chinese medicine.
