Reduction of dietary sodium by reduction of sodium in foods is a current industry target. Quantitative information on consumer knowledge of sodium and reduction of dietary sodium is limited. The objectives of this study were to characterize consumer knowledge and awareness of sodium and salt reduction in foods. Consumers (n = 489) participated in a quantitative internet survey designed to gather knowledge and attitudes towards dietary sodium, sodium in foods, and health. Eating habits and food consumption characteristics, knowledge of salt and sodium, and interest in health and wellness were probed. Saltiness believe and sodium knowledge indices were calculated based on correct responses to salt levels in food products. Kano analysis was conducted to determine the role of nutrition labels and satisfaction/dissatisfaction of foods. Consumers were aware of the presence of sodium in "salty" foods, and that sodium was part of salt. People who had a family history of certain diseases associated with a higher intake of dietary sodium did not necessarily have more knowledge of the relationship between sodium intake and a specific disease compared to consumers with no family history. Sodium content on the food label panel did not influence consumer dissatisfaction; however, sodium content did not necessarily increase consumer product satisfaction either. The addition of a healthy nutrient (that is, whole grain, fiber) into a current food product was appealing to consumers. For nutrient labeling, a "reduced" claim was more appealing to consumers than a "free" claim for "unhealthy" nutrients such as fat, sodium, and sugar.
This study demonstrated the current state of consumer knowledge on sodium and salt reduction, and consumer perception of the relationship between diets high in sodium and many chronic diseases. Information that may contribute to consumer satisfaction on nutrition panel labeling was also determined.
减少食物中的钠含量以降低饮食中的钠含量是当前行业的目标。关于消费者对钠和减少饮食中钠的了解的定量信息有限。本研究的目的是描述消费者对钠和食物中盐减钠的知识和意识。共有 489 名消费者参与了一项定量网络调查,旨在收集关于饮食钠、食物中的钠和健康的知识和态度。调查了饮食习惯和食物消费特征、对盐和钠的了解程度以及对健康和保健的兴趣。根据对食品中盐含量的正确回答,计算了咸味置信度和钠知识指数。进行了 Kano 分析,以确定营养标签的作用和对食品的满意度/不满度。消费者意识到“咸”食品中含有钠,并且钠是盐的一部分。与没有家族史的消费者相比,有某些与高钠饮食相关疾病家族史的人并不一定对钠摄入量与特定疾病之间的关系有更多的了解。食品标签面板上的钠含量不会影响消费者的不满;然而,钠含量也不一定会增加消费者对产品的满意度。在现有食品中添加健康营养素(即全谷物、纤维)对消费者具有吸引力。对于营养标签,“减少”声明比“不健康”营养素(如脂肪、钠和糖)的“免费”声明更吸引消费者。
本研究展示了消费者对钠和盐减钠的当前知识状态,以及消费者对高钠饮食与许多慢性疾病之间关系的看法。还确定了可能有助于消费者对营养标签满意度的信息。
