Perception and knowledge of low‐ and no‐calorie sweeteners in multidisciplinary stakeholders from Spain

Abstract

Low‐ and no‐calorie sweeteners (LNCS) as a category are one of the most thoroughly evaluated additives, and thus their safety has been largely recognised. However, their potential risks and benefits generate great controversy and discussion within countries' food policies and public debate. The goal of this study was to evaluate the degree of knowledge and the perception of key Spanish stakeholders about the role of LNCS in diet, their safety, regulatory issues and their impact on health and wellness, as well as to complete a SWOT analysis of the Strengths, Weaknesses, Opportunities and Threats regarding this topic from their perspective. Participants (n = 45 stakeholders) completed an anonymous survey about their knowledge and perception of LNCS, their role in the diet, safety and legislation, as well as health issues and completed a SWOT analysis. Most of them agreed with aspects related to safety guarantees and authorisation procedure of LNCS; however, certain disparity in their opinion in relation to several of the topics was observed, especially regarding the possible role of LNCS in diet quality and health. Effective communication strategies to inform professionals and the general population, as well as new research that deepens our knowledge of the role of LNCS in weight management and other health outcomes seem to be urgently needed.
