This study evaluated the accuracy of restaurant entrees identified as healthy choices on menus at two fast food restaurant chains. Entrees were purchased at two different locations of each restaurant 35 days apart. Samples were processed in duplicate for total fat contents, sodium analysis, and adiabatic bomb calorimeter for total energy. t-Tests compared (a) the mean experimental values to claimed values for fat, energy, and sodium, (b) nutritional content at different locations for the same restaurant, and (c) the mean experimental values for fat, energy, and sodium levels to the recommended Daily Values. Results indicate that entrees identified as healthy choices at these selected restaurants are in fact healthy choices, are accurately labeled, and are consistent among different locations of the same restaurant chains.
本研究评估了两家快餐连锁店内菜单上标识为健康选择的主菜的准确性。在每家餐厅的两个不同地点购买主菜,时间间隔为35天。样本进行双份处理,以测定总脂肪含量、钠分析以及用绝热弹式量热计测定总能量。t检验比较了:(a) 脂肪、能量和钠的平均实验值与宣称值;(b) 同一家餐厅不同地点的营养成分;(c) 脂肪、能量和钠水平的平均实验值与推荐的每日摄入量。结果表明,在这些选定餐厅中标识为健康选择的主菜实际上是健康选择,标签准确,且在同一家连锁餐厅的不同地点保持一致。
