In the bustling school gates of Vietnam, where parents and children gather each morning, a hidden health concern lurks in the snacks sold by street vendors. While these treats—often fried, sugary, or packed with preservatives—offer quick energy for hungry students, they also pose long-term risks to child nutrition, according to public health experts. With childhood obesity rates rising in Southeast Asia and dietary-related illnesses becoming a growing burden, Vietnamese parents are increasingly scrutinizing the foods their children consume outside school walls. But what exactly are these snacks, and why should families be wary?
Vietnam’s school gates have long been a hub for informal food vendors, offering convenience but raising alarms among nutritionists. A 2023 study by the World Health Organization (WHO) highlighted that nearly 60% of urban Vietnamese children consume ultra-processed snacks daily, with a significant portion purchased near schools. These snacks—ranging from fried dough sticks (*bánh tráng nướng*) and sweet potato chips to sugary drinks—are often high in sodium, unhealthy fats, and added sugars, contributing to metabolic risks like diabetes and cardiovascular disease. Meanwhile, local health campaigns, such as those led by the Ministry of Health of Vietnam, have emphasized the need for balanced diets, yet enforcement of nutrition standards for street food remains inconsistent.
The problem extends beyond individual health. Poor dietary habits in childhood can lead to lifelong patterns, exacerbating Vietnam’s public health challenges. According to the United Nations Children’s Fund (UNICEF), nearly 1 in 3 Vietnamese children under five is at risk of stunting due to malnutrition, while obesity rates among older children have surged by 20% over the past decade. Experts warn that unregulated school-gate snacks worsen this dual burden, offering empty calories that displace nutritious meals. “The foods sold outside schools are often marketed as affordable and convenient, but they lack the vitamins and minerals children need for growth and cognitive development,” says Dr. Nguyen Thi Kim Lien, a pediatric nutrition specialist at the National Institute of Nutrition in Hanoi.
What Are the Most Common School-Gate Snacks—and Why Are They Risky?
Street vendors near Vietnamese schools typically sell a narrow range of snacks, most of which are energy-dense but nutrient-poor. The most prevalent include:

- Fried dough sticks (*bánh tráng nướng*): Deep-fried rice paper rolls, often coated in sugar or sweet sauce. A single serving can contain over 500 calories and 20 grams of fat, with minimal fiber or protein.
- Sweet potato chips: While marketed as a healthier alternative, many brands use hydrogenated oils and excessive salt to enhance flavor and shelf life.
- Instant noodles and soups: Convenient but loaded with sodium (often exceeding 1,500 mg per serving) and MSG, which can contribute to high blood pressure in children.
- Sugary drinks and juices: Bottled teas, soda, and fruit drinks with added sugar—sometimes containing up to 30 grams per can—are commonly sold alongside snacks.
- Candied fruits and nuts: Glazed with syrup or coated in chocolate, these treats provide rapid sugar spikes without nutritional benefits.
While these snacks may seem harmless in minor quantities, their regular consumption aligns with global trends linking ultra-processed foods to childhood obesity, dental caries, and even behavioral issues like hyperactivity. A 2024 report by the WHO Western Pacific Regional Office noted that children who frequently consume such foods are twice as likely to develop metabolic syndrome by adolescence. “The issue isn’t just about calories,” explains Dr. Lien. “It’s about the displacement of whole foods—fruits, vegetables, lean proteins—that are critical for development.”
Regulatory Gaps: Why Are These Snacks Still Sold Near Schools?
Despite growing awareness, Vietnam lacks comprehensive regulations on street food sold near educational institutions. While the Ministry of Health has issued guidelines on food safety and nutrition labeling, enforcement is decentralized, leaving local authorities to interpret and apply rules inconsistently. Some cities, like Ho Chi Minh City, have piloted “healthy school zone” policies restricting the sale of high-sugar or high-fat snacks within 100 meters of schools, but these measures are not nationwide.

Parents and advocacy groups have also faced challenges in holding vendors accountable. Many operate informally, without business licenses or adherence to hygiene standards. A 2025 survey by the Vietnam News Agency found that 70% of school-gate vendors reported receiving no training in nutrition or food safety, and only 30% displayed basic nutritional information on their products. “The lack of regulation creates a loophole that prioritizes profit over children’s health,” says Tran Thi Mai, a member of the Vietnam Nutrition Association.
What Can Parents Do to Protect Their Children?
Given the regulatory gaps, parents play a crucial role in mitigating risks. Here are evidence-based strategies to encourage healthier choices:

- Pack nutritious alternatives: Pre-cut fruits, nuts, yogurt, or whole-grain snacks can satisfy hunger without the pitfalls of ultra-processed foods.
- Educate children about food labels: Teach them to recognize high sugar, salt, and fat content by checking for terms like “hydrogenated oils,” “high-fructose corn syrup,” or “added MSG.”
- Advocate for school policies: Parents can collaborate with local schools to establish “nutrient-rich snack zones” or partner with vendors to offer healthier options.
- Monitor portion sizes: Even “healthier” snacks like fresh fruit should be portion-controlled to prevent overeating.
- Engage with community health programs: Organizations like the UNICEF Vietnam and local nutrition institutes often host workshops on child nutrition.
For those seeking verified resources, the Ministry of Health’s nutrition portal provides guidelines on balanced diets for children, while the WHO’s Vietnam office offers updates on public health campaigns targeting ultra-processed foods. Parents can also report unsafe vendors to local health departments, though enforcement timelines vary by region.
Looking Ahead: Policy and Public Health Initiatives
Efforts to address the school-gate snack crisis are gaining momentum. In 2025, the Vietnamese government announced plans to strengthen the Food Safety Law, including provisions for mandatory nutrition labeling on street foods and stricter licensing for vendors operating near schools. Meanwhile, NGOs are pushing for “healthy school zone” legislation, modeled after successful programs in Thailand and Singapore, where similar regulations have reduced children’s exposure to unhealthy snacks by up to 40%.
The next critical checkpoint will be the 2026 National Nutrition Strategy Review, scheduled for October 2026, where policymakers will assess progress on reducing childhood obesity and malnutrition. Stakeholders, including parents, health experts, and vendors, are encouraged to submit feedback via the Ministry of Health’s public consultation portal.
As Vietnam continues to modernize its food systems, the choices made at school gates today will shape the health of its youngest generation for decades. For parents navigating this landscape, vigilance and advocacy remain the most powerful tools.
