Food-based dietary guidelines (FBDG) have primarily been designed for the consumer to encourage healthy, habitual food choices, decrease chronic disease risk and improve public health. However, minimal research has been conducted to evaluate whether FBDG are utilised by the public. The present review used a framework of three concepts, awareness, understanding and use, to summarise consumer evidence related to national FBDG and food guides. Searches of nine electronic databases, reference lists and Internet grey literature elicited 939 articles. Predetermined exclusion criteria selected twenty-eight studies for review. These consisted of qualitative, quantitative and mixed study designs, non-clinical participants, related to official FBDG for the general public, and involved measures of consumer awareness, understanding or use of FBDG. The three concepts of awareness, understanding and use were often discussed interchangeably. Nevertheless, a greater amount of evidence for consumer awareness and understanding was reported than consumer use of FBDG. The twenty-eight studies varied in terms of aim, design and method. Study quality also varied with raw qualitative data, and quantitative method details were often omitted. Thus, the reliability and validity of these review findings may be limited. Further research is required to evaluate the efficacy of FBDG as a public health promotion tool. If the purpose of FBDG is to evoke consumer behaviour change, then the framework of consumer awareness, understanding and use of FBDG may be useful to categorise consumer behaviour studies and complement the dietary survey and health outcome data in the process of FBDG evaluation and revision.
基于食物的膳食指南（FBDG）主要是为消费者设计的，旨在鼓励健康、习惯性的食物选择，降低慢性病风险，改善公众健康。然而，很少有研究评估公众是否利用了 FBDG。本综述采用了三个概念的框架，即意识、理解和使用，来总结与国家 FBDG 和食物指南相关的消费者证据。对九个电子数据库、参考文献列表和互联网灰色文献进行了搜索，共检索到 939 篇文章。预先确定的排除标准筛选出 28 项研究进行综述。这些研究包括定性、定量和混合研究设计、非临床参与者、与公众的官方 FBDG 相关、并涉及消费者对 FBDG 的意识、理解或使用的测量。意识、理解和使用这三个概念经常被交替讨论。然而，报告的消费者对 FBDG 的意识和理解的证据要多于消费者对 FBDG 的使用。28 项研究在目的、设计和方法上存在差异。研究质量也存在差异，原始定性数据和定量方法细节经常被省略。因此，这些综述结果的可靠性和有效性可能受到限制。需要进一步研究来评估 FBDG 作为公共卫生促进工具的效果。如果 FBDG 的目的是引起消费者行为的改变，那么 FBDG 的消费者意识、理解和使用框架可能有助于对消费者行为研究进行分类，并在 FBDG 的评估和修订过程中补充饮食调查和健康结果数据。
