Duplicate diets of three days were collected. The diets represented general living standard of male adults. There were three types of subjects: city inhabitants in group 1, northern peasants in group 2, and southern peasants in group 3. The diets were analyzed to calculate the average per capita intake of various minerals, energy, fiber and phytic acid. The assessment of intake according to the values of RDA, ESADDI and ADI shows the following results: Zn is low, Ca comes up to 2/3 of RDA, P reaches 88%-133% of RDA, Fe appears enough to attain the standard, but the availability should be considered. The contents of Se and I in each group was varied. Even though the intake of Se is low, it reaches the minimum requirement. Since I is being supplemented for all the people, it would not be deficient. The intake levels of Cu, Mo and Cr achieve or surpass the minimum values of ESADDI. Mn intake exceeds the maximum value of ESADDI, but the highest intake was only 10. 5 mg, which is far from poisoning level. High Na and low K intakes are specific defects of Chinese diets. The level of Cd, Hg and Pb is far apart from toxicosis. As for the amount of As intake, only in group 3 is higher than ADI by 29%. The energy is full. Dietary fiber is suitable. The intake of phytic acid of northern peasants is higher than that of southern peasants and city inhabitants, but it would be harmless.
