Salt warning labels on restaurant menus have been shown to be highly effective in encouraging consumers to make healthier choices, according to a recent study published in The Lancet Public Health. The research, led by Dr. Rebecca Evans at the University of Liverpool, is the first of its kind in the UK and included both online and real-world randomized controlled trials.
The study, titled “Salt warning labels in the out-of-home food sector: online and real-world randomised controlled trials,” found that salt warning labels on menus helped people become more aware of the salt content in their food and led to a significant reduction in the amount of salt ordered. In the online trial with over 2,300 participants, salt warning labels were perceived as effective in discouraging selection of high-salt items and resulted in a reduction of 0.26g of salt per meal. In the real-world trial conducted at a Liverpool restaurant with 454 participants, labeled menus also prompted greater awareness of salt content and reduced salt ordered by 0.54g per meal.
The study found that the labels were equally effective across different demographics, suggesting that they could be a useful tool for all consumers. Public support for implementing salt warning labels on menus was strong, with two-thirds of participants in favor of the idea as a government policy.
Despite the positive findings, the UK currently lacks mandatory nutrient warning policies in restaurants. The researchers hope that the government will take action to implement menu labeling in line with national nutrition goals. Businesses in the out-of-home food sector are selling menu items that contain excessive amounts of salt, contributing to health issues like high blood pressure. The study emphasizes the need for better regulation in the food industry to promote healthier options for consumers.
Overall, the research adds to the growing body of evidence supporting the effectiveness of menu labeling interventions in promoting healthier food choices and reducing population-level salt intake. Collaboration with researchers from other institutions, such as Liverpool John Moores University and the University of California, Davis, was crucial in designing and analyzing the study.
In conclusion, salt warning labels on restaurant menus have the potential to make a significant impact on public health by encouraging consumers to make healthier choices and reduce their salt intake. The study highlights the importance of implementing menu labeling policies in the out-of-home food sector to improve the overall health of the population.
