The dietary survey adopted a combination of family weighing method and non-continuous 3 d 24 h review inquiry method to collect food consumption data and the intake of various foods and nutrients per standard person per day was calculated.ResultsThe urban residents in Jiangxi Province consumed excess livestock and poultry meat， oil and salt， the intakes per standard person per day were 111.70， 31.06 and 7.78 g， respectively.
