The trace element and macronutrient contents of 35 different meals-on-wheels received by seven housebound elderly people have been analysed. The contribution these meals made to the existing Recommended Daily Allowance or the Safe and Adequate Dietary Intake as well as the overall daily nutrient intake was assessed. In general the meals provided adequate amounts of energy, protein, calcium, phosphorus, potassium and iron. Levels of magnesium, manganese, copper, chromium and zinc were low in comparison with some recommended intakes. In addition the meals appeared to contain a relatively high level of sodium. Recommendations for the nutrient content of meals-on-wheels have been made.
对7位居家老人收到的35份不同送餐的微量元素和常量营养素含量进行了分析。评估了这些餐食对现有推荐每日摄入量或安全充足膳食摄入量以及总体每日营养摄入量的贡献。总体而言，这些餐食提供了足够量的能量、蛋白质、钙、磷、钾和铁。与一些推荐摄入量相比，镁、锰、铜、铬和锌的含量较低。此外，这些餐食似乎含有相对较高水平的钠。已对送餐的营养成分提出了建议。
