Do Free School Lunches Help or Hurt Child Health? A Closer Look

INTRODUCTION

According to the World Population Review, 123 countries have implemented large-scale school feeding programs, while 14 countries still lack such initiatives. [1] Meanwhile, recent data from the UN World Food Programme shows that approximately 466 million children at pre-primary, primary, and secondary levels are now being reached through school meal programs worldwide – an increase of about 48 million since 2022. [2] These numbers highlight that even in today’s developed world, a substantial number of children continue to rely on school lunches for access to nutritious food. This raises a critical question: are school lunches truly promoting child health, or could they be doing more harm than good?

THE ROLE OF SCHOOL LUNCHES IN CHILD'S NUTRITION

A standard free school meal is typically expected to include one portion of fruit and one portion of vegetables, with different types of fruit and vegetables offered over the course of a week. It should also provide one or more servings of starchy food, wholegrain cereals and non-dairy protein daily. Confectionery, chocolate, or chocolate-coated products should not be allowed, and foods containing pastry or deep-fried items should be limited. Only healthier drink options should be permitted, with the first priority given to clean, plain water. [3, 4]

Establishing healthy eating habits early in life is crucial for promoting long-term public health. Providing a supportive environment, such as schools that offer nutritious meals – especially when these meals are free or subsidized – can benefit children from all socioeconomic backgrounds. These meals often make up a significant portion of a child’s diet during a critical period of growth and development. [5]

Nutritious school meals can influence children’s future outcomes through various pathways. Most directly, they support health and physical development. Nutrition is one of the key environmental factors that influences height and has a more significant effect during the postnatal period than the prenatal stage.

The School Meals Coalition, a collaborative effort led by Member States, aims to ensure that every child receives a healthy, nutritious meal in school by 2030. The initiative focuses on restoring access to school meal programs disrupted by the COVID-19 pandemic, supporting low-income countries in reaching vulnerable populations, and promoting the provision of safe, nutritious, sustainably produced food along with diverse and balanced diets. [6]

The following table outlines free school meal programs implemented across various countries.

THE POSITIVE SIDE: HOW SCHOOL LUNCHES IMPROVE HEALTH

A notable example of the benefits of school lunch programs is the introduction of Free School Meals across London in 2023. Following the rollout, children reported feeling less anxious about food availability at school and were more open to trying new foods. Many also expressed a greater sense of fairness, belonging, and community, while several families observed improvements in their children’s mental wellbeing. [3] This highlights the strong connection between children’s mental health and their nutrition, underscoring how regular, nutritious meals can contribute to cognitive development.

Research further indicates that children who receive free school meals tend to have significantly better body weight outcomes. They are more likely to maintain a healthy weight, are less prone to obesity, and often have lower BMI levels. By consistently providing nutritious options, school lunches can help instill lifelong healthy eating habits. [26, 27] A nationwide study in junior high schools in Japan reinforces these findings, emphasizing the critical role of both balanced nutrition and dietary education. [28]

Another key point is that home-packed lunches often fall short of nutritional standards, making free school meals a valuable alternative. These programs also help alleviate the financial and logistical burden on parents who may struggle to provide nutritious meals daily. [29] Research shows that children from lower socioeconomic backgrounds benefit the most, with improved dietary intake, making school lunches a meaningful step toward achieving food security for all. [30]

Beyond nutrition, school meal programs also boost local economies by creating jobs for cooks, food handlers, nutritionists, and other support staff. In many areas, they promote inclusive employment by offering opportunities to youth, women, and marginalized groups. [27]

Despite these advantages, it’s important to also acknowledge and address the limitations and potential downsides of free school lunch programs.

THE PROBLEMS: WHERE SCHOOL LUNCHES FALL SHORT

For many years now, the growing accessibility and low cost of ultra-processed foods have led to their widespread use, including in school settings. Their presence in school lunches can be attributed to a mix of cultural norms, supply chain limitations, and practical hurdles. Challenges like managing perishable ingredients, avoiding food waste, and the absence of skilled staff such as nutritionists or cooks – along with inadequate kitchen facilities – often push schools to opt for processed meals instead of prioritizing fresh, wholesome options. [31]

In Mexico, studies show that school lunches – whether bought or brought from home – often consist of ready-made meals and sugary drinks, with no dietary pattern considered healthy. Most of the energy came from sugars and ultra-processed foods. [4] Cost is another major barrier. Research indicates that lower-cost school menus often have the lowest Healthy Eating Index (HEI) scores, suggesting a compromise between affordability and nutritional value. [32]

In the U.S. and other Western countries, school lunches frequently include fast food items like burgers, tacos, and fried chicken. These meals are high in fat, saturated fat, and calories, putting children at greater risk of obesity and related health issues. [33]

OTHER INFLUENCING FACTORS

The home environment is a key determinant in shaping children's eating habits. Parents serve as primary role models and gatekeepers of their children’s dietary behaviors. Their own snacking habits, along with the rules they set around snacking, are strongly linked to their children’s consumption patterns. Additionally, parents’ level of education and nutritional awareness are also significant predictors of children’s dietary choices. Interestingly, the nature of parental influence varies depending on whether the food is healthy or unhealthy. For example, maternal support is positively linked to adolescents bringing nutritious items to school and negatively associated with purchasing sugary snacks in or around school. Physical activity is another vital factor that significantly impacts children’s overall health and wellbeing. [34]

Another barrier to participation in free or reduced-price meal programs can be social stigma, limited awareness, or difficulties in the enrollment process. [35]

The food environment surrounding schools also plays a role. Many schools are located near a high density of unhealthy food outlets, with a median of 17 such retailers per school. Research has shown that most food products marketed toward children are of poor nutritional value, yet they are still widely consumed. [36] Peer influence is another contributing factor in children’s food choices. Social dynamics and the desire to conform can drive children toward less nutritious options, especially when food decisions are made in the presence of peers. [37]

These examples are not an exhaustive list of influencing factors, underscoring the importance of careful planning and effective implementation of free school lunch programs.

CONCLUSION: SO, DO FREE SCHOOL LUNCHES HELP OR HURT?

In examining both the benefits and challenges of school lunch programs, it’s clear they hold great potential to support children's health – promoting better nutrition, mental wellbeing, and food security. However, issues such as reliance on ultra-processed foods, unequal access, and external influences like home environments and peer pressure can undermine these benefits. To truly harness the power of school lunches, a strong focus on meal quality, nutrition education, and equitable access is essential. Continued reform – through informed policymaking, increased parental engagement, and incorporating student voices – is key to creating a system that nourishes not only children’s bodies but also their long-term health and development.
