Determine the extent to which labeling of food products informs about salt consumption.
A critical and systematic analysis was conducted of 9 studies selected out of a total of 133 studies. The studies were collected by reviewing the scientific literature on interventions conducted in the human population aimed towards reducing salt consumption through label messaging. All of the information was obtained by direct consultation and by Internet from the scientific literature collected in several databases.
Out of the 133 articles recovered, after the inclusion and exclusion criteria were applied, 9 studies were selected for review. All of them took into account the ability of the study population to interpret and understand salt content labeling in foods.
Food consumers understand and value easily recognizable logos more than the information found on nutritional composition labels. Therefore, use of alternative logos that facilitate this information and are also standardized could be justified. This situation is reinforced because the inclusion of symbols that are easily understandable favors the most adequate choice by consumers.
确定食品标签在多大程度上能告知人们盐的摄入量。
对从133项研究中挑选出的9项研究进行了批判性和系统性分析。这些研究是通过回顾关于针对人群开展的旨在通过标签信息减少盐摄入量的干预措施的科学文献收集而来的。所有信息均通过直接咨询以及从多个数据库收集的科学文献中通过互联网获取。
在检索到的133篇文章中，应用纳入和排除标准后，挑选出9项研究进行综述。所有研究都考虑了研究人群解读和理解食品中盐含量标签的能力。
食品消费者对易于识别的标志的理解和重视程度高于营养成分标签上的信息。因此，使用便于传达此类信息且标准化的替代标志是合理的。由于包含易于理解的符号有利于消费者做出最恰当的选择，这种情况进一步得到强化。
