New Zealand primary schools are surrounded by an average of 45 food outlets, with nearly four times more unhealthy shops than healthy ones, yet school cafeteria menus show only weak connection to this surrounding food environment. According to Gram Research analysis of 71 schools, while 35.5 percent of school cafeteria items are unhealthy red foods, schools vary widely in their menu choices regardless of neighborhood pressure, suggesting that school policies and support matter more than zoning alone.
Researchers in New Zealand studied the food environment around 71 primary schools to understand how nearby restaurants and takeout shops affect what kids eat at school. They found that schools are surrounded by an average of 45 food outlets, with nearly four times more unhealthy options than healthy ones. Interestingly, while the neighborhood was full of junk food shops, school cafeteria menus didn’t always reflect this pressure. The study shows that poorer neighborhoods had more unhealthy food outlets nearby, raising concerns about fairness in health. According to Gram Research analysis, simply controlling what’s sold around schools may not be enough; schools need better support to stick to healthy menu guidelines.
Key Statistics
A cross-sectional study of 71 New Zealand primary schools found an average of 45 food outlets within 1.6 kilometers, with unhealthy shops outnumbering healthy ones by nearly 4 to 1 (23 versus 6 outlets).
School cafeteria menus in the 2026 New Zealand study comprised only 19.7 percent healthy green items, while 35.5 percent were unhealthy red foods and 35.1 percent were occasional amber foods.
Research on 71 New Zealand primary schools revealed that schools in more deprived neighborhoods had significantly greater exposure to unhealthy food outlets, reinforcing health inequity.
The 2026 cross-sectional analysis found only a weak association between external food outlet density and school cafeteria menu healthiness, suggesting school policies matter more than neighborhood food environment.
The Quick Take
- What they studied: How many fast food and healthy food shops are near primary schools in New Zealand, and whether this affects what food schools serve in their cafeterias.
- Who participated: Seventy-one primary schools across New Zealand. Researchers mapped all food outlets within about one mile of each school using Google Maps data.
- Key finding: Schools were surrounded by an average of 45 food outlets, but unhealthy shops outnumbered healthy ones by nearly 4 to 1. School cafeteria menus showed only weak connection to this surrounding food environment.
- What it means for you: Even though your school might be surrounded by takeout shops, your school cafeteria’s menu choices depend more on school decisions than neighborhood pressure. However, kids in poorer areas face more unhealthy food options nearby, which isn’t fair.
The Research Details
This was a cross-sectional study, which means researchers took a snapshot in time rather than following schools over months or years. They collected data from 71 New Zealand primary schools that shared their cafeteria menus. Using Google’s Places API (a tool that maps businesses), they identified every food outlet within 1.6 kilometers (about one mile) of each school. They then scored each outlet as healthy or unhealthy based on what type of food it sold. They also rated school cafeteria menus using a traffic light system: green for healthy foods, amber for occasional treats, and red for unhealthy foods. Finally, they looked for patterns between the types of shops nearby and what schools actually served.
Understanding the food landscape around schools helps policymakers decide whether to create rules about where fast food shops can open near schools. This study provides real data about whether such rules would actually change what kids eat at school. It also reveals whether poorer neighborhoods face unfair exposure to unhealthy food options.
This study provides a useful snapshot but has limitations. It only looked at one point in time, so we can’t tell if changes in nearby shops lead to changes in school menus. The study included 71 schools, which is a moderate sample size. The researchers used objective data from Google Maps and school menus, which is reliable. However, the weak connection they found between neighborhood food outlets and school menus suggests other factors matter more than location alone.
What the Results Show
The food environment around New Zealand primary schools is heavily tilted toward unhealthy options. On average, each school had 45 food outlets nearby, but only 6 were healthy compared to 23 unhealthy ones. This means kids walking near school encounter junk food shops about four times more often than healthy food shops. School cafeteria menus showed a concerning pattern: only 19.7 percent of items were healthy green foods, while 35.1 percent were occasional amber foods and 35.5 percent were unhealthy red foods. This means more than two-thirds of school cafeteria options were either occasional treats or outright unhealthy. Surprisingly, there was only a weak connection between the number of unhealthy shops nearby and what schools chose to serve. Some schools surrounded by many fast food outlets still offered healthy menus, while others didn’t.
The research revealed an important fairness issue: schools in more deprived (poorer) neighborhoods had significantly more unhealthy food outlets nearby. This means kids in lower-income areas face greater pressure to eat junk food both at home and in their neighborhood. The median health score of food outlets was negative 3.12, indicating the overall food environment leans heavily unhealthy. The study also found that school cafeteria menu quality varied widely, suggesting that school policies and leadership matter more than neighborhood pressure.
Previous research suggested that having many fast food shops near schools would push schools to serve unhealthier food. This study challenges that assumption by showing the connection is weaker than expected. Other research has confirmed that poorer neighborhoods tend to have more unhealthy food outlets, which this study also found. The findings suggest that simply restricting where fast food shops can open may not solve the problem if schools aren’t supported in making healthy choices.
This study only captured one moment in time, so we can’t prove that nearby shops cause schools to change their menus. The study didn’t measure what kids actually ate, only what was available. It didn’t account for other factors that influence school menu choices, such as budget, staff training, or parent preferences. The study only included schools that volunteered to share their menus, which might mean healthier schools were more likely to participate. Finally, the weak association found might reflect that schools make menu decisions based on factors other than their neighborhood food environment.
The Bottom Line
Schools should receive stronger support and training to follow national nutrition guidelines, regardless of what food shops surround them. Policymakers should consider zoning rules to limit unhealthy food outlets near schools, especially in poorer neighborhoods, to promote fairness. However, these rules alone won’t solve the problem; schools need resources, staff training, and accountability to serve healthy food. Confidence level: Moderate, based on this single cross-sectional study.
Parents, school administrators, and policymakers should care about these findings. If you’re a parent, this research shows that your school’s menu choices depend more on school leadership than neighborhood pressure, so advocating for healthy cafeteria policies matters. School leaders should recognize that supporting healthy menus requires active effort, not just hoping neighborhood conditions will help. Policymakers should use this as evidence that zoning rules need to be paired with school support programs.
Changes to school cafeteria menus can happen relatively quickly if schools commit to it, potentially within one school year. However, broader changes to the neighborhood food environment through zoning regulations take much longer, often several years. Kids may see health benefits from improved school meals within weeks to months if they eat most meals at school.
Frequently Asked Questions
Does having fast food shops near schools make kids eat unhealthier food?
