A comprehensive study has found that many of the UK's largest restaurant chains are not meeting voluntary targets set by the government for reducing sugar, salt, and calorie content in their food offerings. The research, published on May 5th in the journal PLOS Medicine, analyzed menu items from the 21 highest-grossing restaurant chains in the UK in 2024. The findings indicate a significant gap between the targets set and the actual nutritional content of the food served to consumers.
Widespread Non-Compliance with Nutritional Goals
According to the study, only 43% of menu items across these major chains met all the voluntary targets for sugar, salt, and calorie reduction for which they were eligible. This widespread non-compliance suggests that current voluntary measures may not be sufficient to drive the necessary changes in the out-of-home food sector. The report highlights that the adherence to these targets varied considerably, both between different restaurant brands and across various food categories. For instance, items from Papa John's showed the lowest adherence to calorie and salt targets, while Burger King, KFC, Nando's, and Vintage Inns reportedly had zero adherence to sugar reduction targets. Conversely, salads and breakfast items generally showed higher adherence rates compared to desserts and pizzas.
The Push for Healthier Menus and Stricter Oversight
The study's co-author, Lauren Bandy, suggested that voluntary targets alone are not yielding consistent improvements in the nutritional quality of restaurant food. She indicated that stricter regulation in the out-of-home sector could be beneficial, alongside enhanced transparency and accountability from individual food companies. The research underscores that while healthier menus are achievable, they have not yet become the norm across the industry. The findings also noted that restaurants with similar menu styles performed differently in meeting targets, suggesting that menu nutritional quality is not solely dictated by cuisine type, making a shift towards healthier options a more attainable goal for a broader range of food businesses.
Implications for Consumer Health and Future Policy
The consumption of foods high in energy, saturated fat, free sugars, and salt is strongly linked to an increased risk of obesity and diet-related non-communicable diseases. The UK government has introduced a series of voluntary targets, with initial sugar targets intended for 2020, salt targets for 2024, and calorie targets for 2025. This study's publication in May 2026 indicates that these targets, particularly the later ones, are still a point of concern. The research utilized PDF menus and nutritional information from restaurant websites to gather data, providing a comprehensive overview of the sector's performance. The study suggests that a more robust approach, potentially involving stricter regulations or more effective accountability mechanisms, may be necessary to ensure that consumers have access to healthier food choices when dining out or ordering takeaway.
