Survey on salt content in selected food products of fast food restaurants and determination of salt intake awareness among fast food consumers in Klang Valley

Abstract

Introduction: Malaysians are exposed to a high salt diet, which is one of the contributors to the prevalence of hypertension among them. This study aimed to identify the salt content in selected food products of fast food restaurants and to determine the salt intake awareness among fast food consumers. Methods: Salt content data were collected through online survey from the official websites of selected restaurants (Kentucky Fried Chicken, McDonald’s, Subway® and Texas Chicken). The food products were classified into eight food categories (chickenbased, potato-based, rice-based, sandwich, salad, bread, dessert, and sauce). The cross-sectional study on salt intake awareness was conducted among 108 Malaysian adults from these restaurants. A knowledge, attitude and practice (KAP) questionnaire was disseminated online. The salt content and the consumers’ salt intake awareness were analysed using Statistical Products and Service Solution (SPSS) software version 25.0. Results: A total of 105 food products were surveyed in this study. Sauce products contained the highest salt content (1.9±0.8 g/100g), followed by bread (1.2±0.3 g/100g), potato-based (1.2±0.4 g/100g), chicken-based (1.2±0.3 g/100g), sandwich (1.1±0.6 g/100g), rice-based (0.7±0.3 g/100g), salad (0.4±0.2 g/100g), and dessert (0.3±0.4 g/100g). For the KAP study, a total of 108 consumers had participated and mostly (48.2%) had a fair level of salt intake awareness. Conclusion: Most food products of fast food restaurants contained high salt content and majority of fast food consumers had a fair level of salt intake awareness. More strategic interventions are needed to control the salt intake among adults in Malaysia
