An assessment of the food and nutrient intake of 81 male and 35 female University students was conducted using structured questionnaires and 24-hr. diet recall procedures. The contribution of Street Foods (SF) to their nutrients intakes was also assessed. The major dietary sources of nutrients for both groups were Cereals, Roots and Tubers and Legumes. Energy intake by males (9.81 MJ or 83.9% RDA) was significantly (p < 0.05) higher than intake (8.59 MJ or 81.8% RDA) by female subjects. Street Foods contributed 50.3% and 48.3% of energy to male and female subjects respectively. Total Protein intake approximated RDA for both groups although on average only 25% of this was from animal sources. Intakes of minerals and vitamins were generally below RDA except for Calcium and vitamin A. Female subjects had significantly higher intakes of Iron, Thiamin and vitamin A than males. Overall Street food's contribution to RDA ranged from 23.0% (Iron in males) to 80.0% (vitamin A, also in males).
采用结构化问卷和24小时饮食回顾法，对81名男大学生和35名女大学生的食物和营养摄入情况进行了评估。同时评估了街头食品（SF）对他们营养摄入的贡献。两组学生营养的主要膳食来源是谷类、块根类、块茎类和豆类。男性的能量摄入量（9.81兆焦耳或推荐膳食摄入量的83.9%）显著高于女性（8.59兆焦耳或推荐膳食摄入量的81.8%）（p<0.05）。街头食品分别为男性和女性提供了50.3%和48.3%的能量。两组的总蛋白质摄入量均接近推荐膳食摄入量，不过平均而言，其中只有25%来自动物来源。矿物质和维生素的摄入量普遍低于推荐膳食摄入量，钙和维生素A除外。女性受试者的铁、硫胺素和维生素A摄入量显著高于男性。总体而言，街头食品对推荐膳食摄入量的贡献范围从23.0%（男性的铁）到80.0%（男性的维生素A）。
