【Abstract】 objective: To comprehend the structure of the foods of corpulent early youths as well as to provide the scientific basis for food guide. Method: Diagnose the target whose body weight exceeded the 20% of standard body weight as corpulence, amounted to 60 cases. Collected the food of 5 days with the method of keeping accounts. Determined the contents of Ca?Fe and Zn in blood serum with atomic absorption spectrophotometer.Results: The RNI of quantity of energy was 112%. The fat percent of the total quantity of heat was 38%, The Ca? VA and VB2 were not enough absorbed. The density of Fe and Zn in blood serum reached the normal level. The t senum contents of Ca were lower, it’s percent was 10%. Conclusion: The nutrition of corpulent early youth isn’t balanced. The energy taken is too much. The Ca?VA and VB2 is not. The food should be balanced. The absorption the fat and the total quantity of energy should controlled.更多还原
