这项研究是为了建立沙特饮食中具有代表性的食物的硒数据库，并估计沙特人的膳食硒摄入量。每种食品的三个样本都是从市场上购买的。样品经充分匀浆后，用电感耦合等离子体质谱分析一式三份。富硒来源为肉类(0.216~0.658 mU g/g)、蛋类(0.226 mU g/g)和谷类及谷类制品(0.043~0.165 mU g/g)。蔬菜和水果中含有微量的硒(0.001-0.067微克/克)。主要食物来源为谷类及谷类制品(30.2%)、豆类(24.7%)和肉类(20%)。计算每日Se摄入量时，考虑到可食用部分中这种元素的浓度和来自两个来源的每日消费数据：(A)粮食及农业组织(粮农组织)提供的KSA食物平衡表；(B)来自吉达200个家庭的调查问卷。结果表明，两种来源的硒的日摄入量分别为75-121.65微克/人/天。(C)2009年沙特国王大学。版权所有。
This study was conducted to create a selenium database for the representative food items in Saudi diet and to estimate the dietary selenium intake of Saudi Arabians. Three samples for each food item selected were purchased from the markets. Each pooled sample was analyzed in triplicate by ICP-MS after thorough homogenization. The rich sources of selenium were meats (0.216-0.658 mu g/g), eggs (0.226 mu g/g) and cereals and cereals products (0.043-0.165 mu g/g). Vegetables and fruits contained trace amounts of selenium (0.001-0.067 mu g/g). The major food sources of selenium intake were cereals and cereals products (30.2%), legumes (24.7%) and meats (20%). The daily intake of Se was calculated taking into account the concentration of this element in the edible part and the daily consumption data which were derived from two sources, (a) the food balance sheet of KSA given by Food and Agriculture Organization (FAO) and (b) from questionnaires distributed among 200 families in Jeddah. The results showed that the daily intake of Se according to the two sources is 75.00-121.65 mu g/person/day. (C) 2009 King Saud University. All rights reserved.
