Rapid Evaluation of Saudi Arabia’s Nutritional Labelling Policy

Abstract

Background: Unhealthy weight is a major global health issue. It's particularly severe in Saudi Arabia (SA) where over 35% of adults are classified as obese. SA’s response has included policies for healthier living, featuring nutritional labelling to help consumers make informed food choices. Aims: This dissertation aims to conduct a rapid systematic review to evaluate the different labelling strategies. Findings will then be used to make evidenced-based recommendations to the existing nutritional labelling policies in SA. Methods: Systematic reviews were first identified from the World Obesity Federation. A rapid search was also conducted in PubMed and Embase from 2021 until January 2024 to identify any recent systematic reviews which may not have been identified by the World Obesity Federation. Search queries included categories on intervention (e.g., nutrition logo, Nutrition Facts, traffic light) and reviews. Online searches were complemented by hand-searching of reference lists as well as the first 20 “related articles” in PubMed for each included systematic review. Gray literature was searched on Google. Results: Sixteen reviews were found. Many identified a positive impact of warning labels, traffic light systems, and color-coded labels on consumer behaviour. However, efficacy depended on several design features (e.g. size, colour and placement) and was increased when part of a multi-component intervention including education and awareness campaigns. Considering SA’s rudimentary nutritional labelling system, the review suggests the adoption of more accessible and interpretative labels, coupled with public health campaigns and pricing strategies, to steer consumers towards healthier alternatives. Conclusion: Evidence from various countries indicate that interpretative labels, such as traffic light systems and warning labels, successfully promote healthier food selections. Subsequent research should concentrate on the enduring impacts of these labelling strategies within Saudi Arabia's distinct socio-cultural setting, investigating demographic variances and the potential role of digital tools in boosting label utilization and understanding.
