背景：在文献中，健康的饮食比不健康的饮食花费更多。目的：本综述的目的是研究食品价格和饮食成本对饮食质量社会经济不平等的贡献。数据来源：对PubMed、Google Scholar和Web of Science数据库进行了系统的文献检索。研究选择：选择与食品价格、饮食质量和社会经济地位相关的出版物。数据提取：在可能的情况下，使用法国国家常用食品及其平均零售价格数据库说明审查结论。数据合成：营养价值较低的食物和质量较低的饮食通常每卡路里的成本较低，往往是社会经济地位较低的群体选择的。一些营养丰富的食品价格低廉，但并不总是可口的，或在文化上为低收入消费者所接受。可接受的健康饮食与更高的成本一致相关。贫困地区的粮食预算不足以确保最佳饮食。结论：饮食质量的社会经济差异可以用健康饮食的高成本来解释。确定营养丰富、负担得起和有吸引力的食物模式应该是消除营养和健康方面社会不平等的优先事项。
Context: It is well established in the literature that healthier diets cost more than unhealthy diets. Objective: The aim of this review was to examine the contribution of food prices and diet cost to socioeconomic inequalities in diet quality. Data Sources: A systematic literature search of the PubMed, Google Scholar, and Web of Science databases was performed. Study Selection: Publications linking food prices, dietary quality, and socioeconomic status were selected. Data Extraction: Where possible, review conclusions were illustrated using a French national database of commonly consumed foods and their mean retail prices. Data Synthesis: Foods of lower nutritional value and lower-quality diets generally cost less per calorie and tended to be selected by groups of lower socioeconomic status. A number of nutrient-dense foods were available at low cost but were not always palatable or culturally acceptable to the low-income consumer. Acceptable healthier diets were uniformly associated with higher costs. Food budgets in poverty were insufficient to ensure optimum diets. Conclusions: Socioeconomic disparities in diet quality may be explained by the higher cost of healthy diets. Identifying food patterns that are nutrient rich, affordable, and appealing should be a priority to fight social inequalities in nutrition and health.
