Abstract

Background

Potassium-enriched salt is a proven dietary intervention for reducing risk of stroke, cardiovascular disease, and premature mortality when used instead of regular table salt. Potassium-enriched salt products are available globally, but the on-pack health claims, product features, and instructions for use are diverse.

Objectives

The objective of this study was to summarize the label features of potassium-enriched salt products available worldwide.

Methods

A content analysis was conducted on the labels of potassium-enriched salt products available for sale in May 2023. Potassium-enriched salt products were identified through a systematic search of literature, major online shopping websites, and Google using similar keywords such as “salt substitute” or “low sodium salt.” Information on product labels was coded relating to health claims, product features, and instructions for use, and were quantitatively summarized.

Results

A total of 117 potential potassium-enriched salt products were identified, with 83 included in the final analysis after excluding products containing no sodium (n = 15), no potassium (n = 5), or that were duplicates (n = 14). There were 23 (28%) products with on-pack claims for health benefits and 36 (43%) with health warnings. Twenty-five (30%) of product labels included descriptions of other product features such as taste and potassium content, and 36 (43%) had instructions for use.

Conclusions

There was large variability in the label features of potassium-enriched salt products identified in this study. Most product labels made no health-related statements, but among those that did, warnings occurred more frequently than statements of health benefits. The diversity in labeling may cause confusion among consumers, and standardized, evidence-based labeling should be developed.

富钾盐产品标签上的健康声明、产品特点和使用说明:内容分析
背景经证实,用富钾盐代替普通食盐可降低中风、心血管疾病和过早死亡的风险。本研究的目的是总结全球现有富钾食盐产品的标签特点。方法对 2023 年 5 月上市的富钾食盐产品的标签进行内容分析。通过使用 "盐替代品 "或 "低钠盐 "等类似关键词对文献、主要在线购物网站和谷歌进行系统搜索,确定了富钾食盐产品。对产品标签上有关健康声明、产品特点和使用说明的信息进行了编码,并进行了定量总结。结果共发现了 117 种潜在的富钾食盐产品,在排除了不含钠(15 种)、不含钾(5 种)或重复(14 种)的产品后,83 种产品被纳入最终分析。有 23 种(28%)产品在包装上标明了健康益处,36 种(43%)产品标明了健康警告。有 25 种(30%)产品的标签包含了对其他产品特性的描述,如口味和钾含量,有 36 种(43%)产品的标签包含了使用说明。大多数产品标签都没有与健康相关的说明,但在有说明的产品标签中,警告的出现频率高于健康益处的说明。标签的多样性可能会给消费者造成困惑,因此应开发标准化的、以证据为基础的标签。
