【Abstract】 Objective: to understand the dietary and nutritional status of young undergraduates. Methods: 176 undergraduates were selected from one university in Qingdao by randomized sampling. 24-hour recalls were done by specialized persons to collect the data of dietary intake and DRIs were used as standard to evaluate the data. Results: The average of energy intake and protein were 2091.6 kcal and 71.3g per day which respectively account for 93% and 95% of RNI. Protein, fat and carbohydrate provided 14%, 25% and 59% of energy respectively. The average intake of retinol, total vitamin E, selenium and ascorbic acid were 89%, 88%, 111% and 75% of RNI respectively. Conclusion: the nutritional status of young undergraduates was well. The ratio of three energy-yielding nutrients was appropriate. Except for vitamin C, the intake of other micronutrients were adequate.更多还原
