Poor diet, resulting from high intake of ultra-processed packaged foods, is increasingly recognised as a key contributing factor to ill health. Food labels provide information on the nutritional content of packaged foods to consumers, which may influence consumption of nutrients such as energy, fat, saturated fat, trans-fats, sodium and added sugars. This review aims to summarise the current evidence for the association between use of food labels and dietary intake. The systematic search was conducted in August 2017 using six databases, with 6325 results. Twenty-six studies were included, including cross-sectional studies (n = 20), a cohort study (n = 1) and randomised controlled trials (n = 5). Studies were assessed using the American Dietetic Association Quality Criteria Checklist. Results were inconsistent in reporting a relationship between diet and food label use but indicated that reading the nutrition facts label is associated with healthier diets, measured by food frequency questionnaires and 24 h recalls. However, there is insufficient research on the association between dietary consumption and use of ingredients lists, serving size information and front-of-pack labels. Using health-related claims may be associated with poor diets, however evidence is inconclusive. Apart from health-related claims, using food labels is associated with healthier diets and should continue to be promoted through policies and education programs. Further research in this area is warranted to provide additional information on the impact of ingredients lists, serving sizes, front-of-pack labels and health-related claims on dietary intake.
不良饮食，源于超加工包装食品的大量摄入，日益被认为是导致健康不良的一个关键因素。食品标签为消费者提供包装食品的营养成分信息，这可能会影响能量、脂肪、饱和脂肪、反式脂肪、钠和添加糖等营养素的摄入。本综述旨在总结目前关于食品标签使用与饮食摄入之间关联的证据。系统检索于 2017 年 8 月在六个数据库中进行，结果为 6325 项。共纳入 26 项研究，包括横断面研究（n=20）、队列研究（n=1）和随机对照试验（n=5）。研究使用美国饮食协会质量标准检查表进行评估。尽管报告称饮食与食品标签使用之间存在关联的结果不一致，但结果表明，阅读营养成分标签与更健康的饮食有关，这是通过食物频率问卷和 24 小时回顾法来衡量的。然而，关于饮食摄入与成分表、份量信息和包装正面标签使用之间关联的研究还不够充分。使用与健康相关的声明可能与不良饮食有关，但证据尚无定论。除了与健康相关的声明外，使用食品标签与更健康的饮食有关，应继续通过政策和教育计划加以推广。需要在这一领域开展进一步的研究，以提供更多关于成分表、份量、包装正面标签和与健康相关的声明对饮食摄入影响的信息。
