Healthful nutrition is crucial for longevity and optimal performance, as it helps reduce the risk of chronic diseases such as heart disease, diabetes, and obesity, all of which are linked to poor dietary habits. In the UK, over 60% of adults are classified as overweight or obese, and around 25% suffer from metabolic syndrome, a condition that significantly increases the risk of cardiovascular disease and type 2 diabetes (Public Health England, 2018; Swinburn et al., 2011). These conditions not only shorten lifespan but also negatively impact quality of life, contributing to physical limitations and cognitive decline (Afshin et al., 2019). Proper nutrition supports cognitive function, enhancing focus, memory, and mental resilience, which are vital for high performance at work and in sports (Baker et al., 2019; Williams et al., 2020). Additionally, for athletes and physically demanding professions, a balanced diet is key to optimizing energy, performance, and recovery (McGuire & Austin, 2017; Williams et al., 2020). On a societal level, poor nutrition is a significant economic burden, with obesity-related illnesses costing the UK billions in healthcare and lost productivity (Haslam et al., 2015; Vainik et al., 2020). Promoting healthful nutrition is essential for improving individual health, well-being and performance.
