Worked solution
A strong essay should evaluate both the strengths of current dietary guidance and the real barriers to following it, reaching a balanced overall judgement. Strengths/effectiveness: guidance such as the Eatwell Guide translates complex nutritional science into a simple, visual proportional model (recommending, broadly, that around a third of intake come from fruit and vegetables, over a third from starchy carbohydrates, with smaller proportions of protein foods and dairy/alternatives, and minimal amounts of foods high in fat, salt and sugar), which is easy to communicate and apply flexibly across most age groups (with age-specific adjustments, e.g. lower-fat dairy generally not recommended for children under 2, or increased protein/calcium emphasis for older adults, as discussed in relation to musculoskeletal health); such guidance is widely embedded in schools (food education), primary care advice, and public health campaigns, giving it broad reach and a consistent, evidence-based message across society. However, several barriers significantly limit its real-world effectiveness: (1) cost — fresh fruit, vegetables, wholegrains and lean protein are often more expensive per calorie than heavily processed, energy-dense foods, making the guidance harder to follow on a low income, a particularly significant barrier given rising food costs; (2) time, cooking skills and knowledge — preparing balanced meals from raw ingredients requires time, confidence and practical skills that not everyone has been taught or has time for amid busy working lives, pushing some towards convenience foods that do not match the guidance; (3) cultural and religious dietary practices — a single generic visual guide may not easily map onto all cultural cuisines or religious dietary rules, meaning some groups may need additional, tailored guidance to apply the underlying principles to their own diet; (4) psychological and behavioural factors — deeply ingrained food habits, taste preference (particularly for high-sugar, high-fat foods), and the pervasive influence of advertising and marketing for less healthy convenience and fast foods can work directly against public health messaging, especially among children and young people. Overall judgement: current dietary guidance is a sound, evidence-based and broadly effective framework in principle, and does successfully raise general awareness of balanced eating, but its practical, population-level effectiveness is significantly constrained by structural barriers (cost, time, cultural fit) and behavioural/psychological barriers (habit, preference, advertising), meaning guidance alone is unlikely to be sufficient without complementary action (e.g. on food pricing, food education, or advertising regulation) to translate awareness into consistent, real-world behaviour change, particularly for lower-income and time-poor households. Final answer: dietary guidance such as the Eatwell Guide is an effective, well-evidenced communication tool in principle, applicable with adjustment across age groups, but its real-world effectiveness is substantially limited by cost, time/skills, cultural fit and behavioural/advertising barriers, meaning guidance alone has only partial effectiveness at the population level.
Marking scheme
Level of response, [20] marks, assessing knowledge of dietary guidance, evaluative discussion of effectiveness and barriers, and Quality of Written Communication (QWC). Level 1 (1–5): a basic, largely descriptive account of dietary guidance (e.g. simply describing the Eatwell Guide) with little discussion of effectiveness or barriers, and limited specialist vocabulary; QWC basic. Level 2 (6–10): a sound account covering the guidance and identifying at least one or two barriers, with some, but limited, evaluative comment on effectiveness; QWC satisfactory, reasonably organised. Level 3 (11–15): a well-developed discussion covering how the guidance is designed to promote healthy eating across age groups, with several distinct, correctly explained barriers (e.g. cost, time/skills, cultural fit, behavioural/advertising influence) and a developing evaluative judgement on overall effectiveness; QWC good, clear and organised, appropriate vocabulary. Level 4 (16–20): a comprehensive, well-balanced and fully evaluative discussion that explains the strengths of current dietary guidance across different age groups AND analyses a full range of barriers (structural: cost, time/skills, cultural/religious fit; and behavioural/psychological: habit, preference, advertising), reaching a fully justified, nuanced overall judgement on the real-world effectiveness of dietary guidance; QWC excellent — fluent, logically structured, using specialist terminology accurately throughout.
