School Meals Do More Than Feed Children: They Boost Health Literacy, Mental Health and Grades

Every school day, millions of children across low- and middle-income countries line up for a plate of food provided not by their families but by their governments and international partners. School feeding programmes have long been justified on the grounds of hunger relief and increased enrolment, but a growing body of research suggests their influence reaches far deeper into a child’s life than the food tray itself. A new study published in Humanities and Social Sciences Communications offers some of the most detailed evidence yet that school nutrition and feeding programmes are linked not only to what children eat, but to how well they understand health information, how they feel psychologically, and how they perform academically. The research, led by Priscilla Adomako Gyasi of Zhejiang Normal University together with colleagues at Jiangsu University, positions school meals as a potential dual-impact strategy serving both global health and education goals simultaneously.

The study was grounded in the Health-Promoting Schools framework, a model developed by the World Health Organization that treats the school as an integrated environment where physical facilities, curriculum, and community engagement all combine to shape pupil wellbeing. Rather than asking the simple question of whether children who receive meals do better than children who do not, the researchers built a more sophisticated causal architecture. They hypothesised that feeding programmes influence academic performance and self-reported physical health through two intermediate mechanisms: health literacy, meaning a student’s ability to obtain, understand and apply health-related information, and mental health, encompassing emotional and psychological wellbeing. In other words, the meal is not the endpoint of the intervention but the starting point of a chain of effects.

To test this model, the team conducted a cross-sectional survey among pupils in basic schools in Ghana, covering both primary and junior high levels, using standardised questionnaires. The choice of setting matters. Resource-constrained contexts such as Ghana’s Ejisu Municipality, where the data were collected with authorisation from the Ghana Education Service, are precisely the environments where school feeding programmes have expanded most rapidly and where questions about their effectiveness carry the greatest policy weight. The researchers obtained ethical clearance from the Institutional Review Board of Jiangsu University and secured written informed consent from all participants, with parents or legal guardians consenting on behalf of children under eighteen.

The analytical approach was structural equation modelling, or SEM, a statistical technique that allows researchers to estimate multiple pathways simultaneously rather than examining each relationship in isolation. This is crucial for a question like school feeding, where nutrition, cognition, emotional state and learning are all entangled. SEM makes it possible to ask whether the association between receiving meals and reporting better grades persists once the indirect routes through health literacy and mental health are accounted for, and to quantify how much of the total effect travels through each mediator. The method also permits formal tests of mediation, distinguishing a genuine transmission mechanism from a mere statistical correlation.

The results supported the study’s central hypothesis. School feeding programmes were positively associated with students’ self-reported academic performance, and health literacy and mental health emerged as significant indirect pathways carrying that association. Children who participated in feeding programmes reported higher health literacy, and higher health literacy in turn was linked to better perceived academic outcomes. Mental health followed a similar logic, functioning as a second conduit between meal provision and learning. Notably, health literacy also mediated the relationship between feeding programmes and students’ perceived physical health, suggesting that meals may teach as well as nourish: a child who eats regularly at school may also absorb knowledge about nutrition, hygiene and bodily wellbeing that translates into healthier self-perception and behaviour.

One of the most striking findings concerned inequality. Effect size analysis indicated that the associations between feeding programmes and student outcomes were stronger in disadvantaged communities. This pattern carries an intuitive explanation rooted in marginal utility. For a child who is food-secure at home, an additional school meal may change relatively little. For a child facing chronic food insecurity, the same meal can stabilise daily energy intake, reduce the cognitive burden of hunger, and free attention for learning. The finding implies that school feeding acts as a compensatory mechanism, delivering its largest benefits precisely where baseline deprivation is greatest, and it aligns with the broader development literature on targeted social protection.

The psychological pathway deserves particular attention. Hunger is not merely a physiological state; it is an emotional experience that can produce anxiety, shame and stress, all of which interfere with concentration and memory. By relieving food insecurity, feeding programmes may lower this psychological burden, and improved mental health then feeds back into academic engagement and performance. The study’s mediation analysis suggests that this route is statistically meaningful, which reframes school meals as a mental health intervention as much as a nutritional one. In educational systems where counselling resources are scarce, a reliable meal may be one of the few scalable tools available to support pupils’ emotional wellbeing.

The implications for policy are direct. The authors conclude that school feeding initiatives may function as dual-impact strategies linked to both Sustainable Development Goal 3 on health and Sustainable Development Goal 4 on education, and they encourage policymakers to integrate meal provision with health education rather than treating the two as separate programmes. This integration logic sits at the heart of the Health-Promoting Schools framework: a canteen that also functions as a classroom, where children learn about balanced diets and hygiene while eating, multiplies the return on every unit of public spending. In resource-constrained settings, where budgets are tight and every intervention competes for scarce funds, evidence that a single programme can advance two Sustainable Development Goals at once is a powerful argument for investment.

As with any cross-sectional study, some caution is warranted in interpretation. Because the data were collected at a single point in time, the analysis identifies associations and statistically modelled pathways rather than definitively proven causal effects, and the outcomes were self-reported by pupils rather than measured through clinical or administrative records. Longitudinal designs and randomised evaluations would strengthen the causal case. Nevertheless, the study’s methodological rigour, its grounding in an established theoretical framework, and its focus on a real-world municipal school system give its findings considerable weight. The mediation results in particular offer something that simple before-and-after comparisons cannot: a mechanistic account of how meals become grades.

The broader message of the research is that the humble school meal is a far more powerful instrument than its modest cost suggests. It is simultaneously a nutrition programme, a health literacy intervention, a mental health support and an academic lever, with its strongest effects concentrated among the children who need it most. As governments and donors weigh the future of school feeding schemes across the Global South, this study provides a compelling empirical case that the benefits extend well beyond the food tray, into the minds, moods and report cards of the pupils they serve.
