Abstract: Abstract：Thenationalconcept of dietary nutrition and health has changed from“eating-full”,“eating-well”to“eating-right”,as China's per capita gross domestic product (GDP) in 2019 reached 10,000 U.S. dollars. Modern diets are gradually movingfrom basic requirement of nutrition and flavor, to three major elements including safety, nutrition and health. The paper putforward a new framework of the dialectical nutrition based on Chinese dietary therapy and modern nutrition. The dialecticalnutrition, based on the“new nutrition science”that proposed by the 18th International congress of Nutrition, aims to explorefood nutrition, human physique and their dialectical relationship, using a dialectical and systematic approach. According to theoverall, comprehensive and balanced nutritional perspective, the framework was then combined with the diet and taste of foodin Chinese dietary therapy, in order to build a whole discipline system from philosophy to science. The evaluation system canbe suitable for the characteristics of Chinese diet, physical classification, and health status. The dialectical nutrition, served asa sort of nutrition discipline, iscomplied with the definition and concept of new modern nutrition, with emphasizing on theinterdisciplinary integration in the range of biology, sociology, and humanities. The purpose of dialectical nutrition was usedto balance the dynamic transformation of food and nutritional physique, in order to achieve human nutrition and health. This isbecause the dialectic method was a theoretical strategywith technical precision and dynamic balance. Therefore, this studyproposed a construction of two framework for 1) the healthy food engineering system based on six attributes, includinggermplasm, habitat, processing, nutrition, function, and bias, and for 2) the nutrition physical engineering system based on sixevaluated indices, including basal metabolism, gastrointestinal macrogenes, nutritional genes, emotional strength, immunity,digestion and absorption ability. A dynamic model of transformation balance has also established based on the big data mining.The integrated frameworks with the dynamic models can form an new engineering system for nutrition and health. Thisproposed system can provide sound basis for the four supporting systems of talents, technology, industry and capital in Chinasociety. The study can innovate the development of the healthy food industry, and upgrade of national healthy consumption, aswell provide scientific dietary guidance for the health of the entire population, and lay a solid healthy foundation for thenational effort to build China into a comprehensive moderately prosperous society.
