Nutrient Intake Status, Existing Problems and Countermeasures of Chinese Residents in the Past 30 Years

Abstract

Nutrients are the basic substances to promote human metabolism and maintain health, and their long-term unreasonable intake will increase the risk of chronic diseases among residents. The time series analysis method was used to comprehensively and systematically analyze the nutrient intake status, existing problems and adverse consequences of Chinese residents in the past 30 years. The analysis results show that the structural imbalance of nutrient intake caused by insufficient overall intake of nutrients, excess partial intake of nutrients and uneven overall intake of nutrients is the main problem of nutrient intake of Chinese residents, which is mainly manifested as "two more and four less", that is, more fat intake, more sodium intake, less mineral intake, less water intake, less vitamins intake, and less dietary fiber intake.There is a significant causal relationship between the long-term structural imbalance of nutrient intake and the high incidence of chronic diseases among Chinese residents. Effective measures can be taken to cope with the high incidence of chronic diseases by controlling the quality of nutrients intake, balancing the amount of nutrients intake, developing good daily eating habits, and improving the overall level of public awareness of nutrients.The research results provide a new theoretical perspective and application path for the prevention and treatment of chronic diseases in China, and have important theoretical value and practical significance for promoting the construction of a healthy China.
