高能量饮食为消费者提供了一种低成本的饮食选择。然而，它们更有可能是营养不良的。在这项研究中，基于法国全国食品消费调查，使用法国食品零售价格来估算饮食成本。成年参与者按能量成本的四分位数进行分层(单位为E/10MJ)。然后比较不同组别的膳食能量密度、能量和营养摄入量。能量成本最低四分之一的参与者能量摄入量最高，能量密度最高的饮食，关键维生素和微量营养素的日摄入量最低。能量成本最高四分位数的参与者能量摄入量较低，饮食中营养成分较高，能量密度较低。然而，他们的日常饮食成本高出165%。在这项观察性研究中，营养密度越高的饮食与更高的饮食成本相关。
Energy-dense diets offer a low-cost dietary option to the consumer. However, they are more likely to be nutrient-poor. In this study, based on the French national food consumption survey, the diet costs were estimated using retail food prices in France. Adult participants were stratified by quartiles of energy cost ( in E/10 MJ). Dietary energy density, energy and nutrient intakes were then compared across groups. Participants in the lowest quartile of energy cost had the highest energy intakes, the most energy-dense diets and the lowest daily intakes of key vitamins and micronutrients. Participants in the highest quartile of energy cost had lower energy intakes, and diets that were higher in nutrients and lower in energy density. However, their daily diet costs were 165% higher. In this observational study, the more nutrient-dense diets were associated with higher diet costs.
