Abstract：Objective To understand the status of dietary structure and nutrient intake among residents in Yuelu District of Changsha City, and to provide references for carrying out targeted nutrition and health education. Methods The food consumption status of residents aged 3 years and above in Yuelu District of Changsha City in 2020 was investigated. Kruskal-Wallis H test was used to analyze the difference in the average intake of dietary and nutrients per reference person per day among residents of different age groups, and then compared with the status of nutrition and health among Chinese residents in 2010-2013, the Chinese Dietary Guidelines and Dietary Reference Intakes of Chinese Residents. Results A total of 392 residents were enrolled into the data analysis, including 192 males and 200 women, and the mean age was (37.39±19.93) years. In 2020, the average intakes of cereals (341.9 g), soybean (33.6 g), eggs (39.9 g), fish, shrimp, crab and shellfish (47.3 g) per reference person per day for the residents in Yuelu District basically reached the recommended nutrient intakes from dietary pagoda, but the intakes of potato (19.5 g), fruits (34.9 g), milk and dairy products (58.9 g) were severely insufficient, with the excessive intakes of livestock and poultry meat (159.7 g), edible oil (44.5 g) and salt (6.4 g). As for the average intake of nutrients per reference person per day, the intakes of protein, vitamin B, vitamin E, sodium, phosphorus and iron met the requirements of recommended nutrient intake (RNI). The energy supply ratios of carbohydrate and fat were 41.3% and 45.0%, respectively, which decreased by 13.7% and increased by 12.1% compared with the national average levels in 2012. Among different age groups, the nutrient intake of residents aged 18-64 years was relatively low, and their energy intake was only 1,821.0 kcal. Conclusion The status of soybeans, nuts, animal food and salt intakes among the residents in Yuelu District of Changsha City in 2020 was improved, but the overall dietary structure and uneven distribution of nutrient intake in all age groups still existed. It is necessary to strengthen propaganda and education on reducing oil and salt, and guide the residents to increase the intakes of potato, fruits, vegetables and milk.
