Healthy Eating in Schools: A Guide to Smart Snacking and Healthy Habits

Why is healthy eating important in schools?

Healthy eating in schools is about more than serving nutritious lunches. It means creating a whole-school culture where pupils have access to balanced food, fresh water, consistent guidance and practical opportunities to learn about nutrition. Clear policies, safe snack choices, positive role modelling and age-appropriate food education can help healthy habits become part of everyday school life.

Schools have an important role to play in helping children understand food, nutrition and the everyday choices that support their health and wellbeing.

This responsibility does not sit with teachers alone. School leaders, school business managers, catering teams, support staff, governors, parents and pupils can all contribute to a positive food culture.

The Department for Education (DfE) describes a whole-school approach as one that considers leadership, food provision, food education and wider wellbeing. It encourages schools to involve pupils and parents, make drinking water easily available and create consistent messages around healthy eating across school life.

Healthy eating can also sit alongside other priorities such as physical activity, pupil wellbeing and sustainability. The aim should not be to make food complicated. It is about creating simple, realistic routines that children can understand and schools can maintain.

What challenges do schools face when promoting healthy eating?

Creating healthier habits across a school community can involve balancing several different considerations.

Schools may need to think about:

• different dietary, cultural and medical needs
• food allergies and intolerances
• school budgets and catering arrangements
• what is offered at breakfast, lunchtime and breaktime
• healthy packed lunch guidance
• access to fresh drinking water
• communication with parents and carers
• pupil preferences
• staff training
• practical food education
• reducing food waste

Consistency can be one of the biggest challenges. Healthy eating is harder to embed when the messages pupils receive in lessons, the dining hall, breakfast clubs and after-school clubs do not match.

A whole-school approach can help make expectations clearer for everyone.

What should schools know about the School Food Standards?

For schools in England, food served in maintained schools and academies must meet the School Food Standards. The standards cover school lunches as well as much of the food and drink provided during the wider school day, including breakfast clubs, mid-morning provision, vending and after-school clubs.

The standards are designed to help schools provide nutritious food and encourage healthy eating habits.

Among the requirements, free, fresh drinking water must be available throughout the school day. The guidance also places restrictions on foods high in fat, salt and sugar and encourages appropriate provision of fruit, vegetables, wholegrain foods, dairy and sources of protein.

School leaders and governing bodies should regularly review their provision and check the latest DfE guidance when making changes. Schools outside England should refer to the relevant requirements for their nation.

How can schools develop a whole-school food policy?

A clear school food policy can give staff, parents, pupils and catering teams a shared understanding of how healthy eating will be supported.

The DfE encourages governing bodies and senior leadership teams to develop a whole-school approach to food provision and food education.

A useful school food policy could consider:

• how pupils and parents can provide feedback on food
• expectations for school catering
• access to free, fresh drinking water
• guidance for healthy packed lunches
• breakfast and breaktime provision
• fruit and vegetable snack breaks
• arrangements for allergies and special dietary requirements
• opportunities for practical cooking and nutrition lessons
• how food is used within celebrations and events
• growing food through a school vegetable garden
• how the school will review its food provision over time

Make the policy practical rather than overly complicated. Staff and families should be able to understand what the school is trying to achieve and why.

Pupil voice can also be valuable. Ask children what they enjoy, what they understand about healthy eating and what would make healthier choices easier for them.

What are examples of healthy snacks for children at school?

Healthy snacks do not need to be complicated.

The NHS recommends fruit and vegetables as the best everyday snack choices for children.

Simple options can include:

• bananas, apples, pears or berries
• carrot, cucumber or pepper sticks
• satsumas or other easy-to-prepare fruit
• chopped vegetables served appropriately for the age group

The appropriate choice will depend on when and how food is being provided. For example, school breakfast clubs may be able to offer foods such as wholemeal toast, porridge or yoghurt as part of a balanced breakfast, while fruit and vegetables provide straightforward options for a mid-morning snack.

Wholemeal foods can also be useful within meals and breakfast provision because they provide fibre and can form part of a balanced diet.

One change from older snacking advice is worth noting: dried fruit is better served as part of a meal rather than as a between-meal snack because it can stick to teeth and contribute to tooth decay.

Whatever is offered, schools should check that it meets their food standards and allergy procedures.

What should schools consider about food allergies?

Food allergies should be considered before introducing any new snack, breakfast or catering provision.

The DfE's allergy guidance states that schools must support pupils with medical conditions, including allergies, and schools and caterers need appropriate allergen information for the food they provide.

Practical steps include:

• maintaining up-to-date information about pupils' allergies
• checking ingredient and allergen information
• communicating changes with catering staff
• reviewing products if suppliers or ingredients change
• avoiding assumptions that a food is suitable for every child
• following individual healthcare plans where required
• making sure relevant staff know how to respond to an allergic reaction

Schools should be particularly careful with nuts and nut products. Even where a particular food may otherwise fit nutritional guidance, the school's allergy policy and the needs of individual pupils must come first.

Why does positive role modelling matter?

Children notice the routines and behaviours they see around them.

That makes positive role modelling an important part of healthy eating in schools. Teachers, support staff and other adults do not need to demonstrate a "perfect" diet. Instead, schools can focus on creating consistent, positive messages around food, hydration and physical activity.

Simple actions can help:

• making water readily available
• speaking positively about trying different foods
• supporting relaxed and sociable mealtimes
• avoiding contradictory messages about healthy eating
• encouraging movement and physical activity alongside nutrition
• involving staff in whole-school wellbeing activities

The goal is to make healthier choices feel normal and achievable rather than turning food into another set of rules for pupils to worry about.

How can schools teach children about nutrition?

Food education gives children the opportunity to understand what they eat, where food comes from and how different foods contribute to a balanced diet.

Lessons can connect healthy eating with Science, Design and Technology, PSHE and wider topics such as sustainability.

Schools could explore:

• the main food groups
• what a balanced diet looks like
• fruit and vegetables
• hydration
• food labels
• where food comes from
• practical cooking
• growing fruit, vegetables and herbs
• seasonal food
• reducing food waste

The NHS Eatwell Guide can provide a useful starting point for discussing a varied and balanced diet with school-age children.

Hands-on classroom nutrition resources can make these discussions more accessible. For example, an Eatwell Guide Floor Mat Bundle or Eatwell Guide Tabletop Activity can allow pupils to sort different foods, discuss food groups and build their own examples of balanced meals. Both resources are currently available through GLS and are designed to support primary food and nutrition learning.

How can growing food help children learn about healthy eating?

Creating a school vegetable garden or growing food in the classroom can turn nutrition into a practical learning experience.

Pupils can plant seeds, care for plants, observe changes over time and learn where food comes from. This can connect healthy eating with Science, environmental education and sustainability.

Schools do not need a large outdoor space to get started. Herbs, salad leaves or other suitable plants can be grown in plant pots or growing trays where space is limited.

Depending on the activity, schools might use gardening equipment, seeds, plant pots, watering cans, growing trays and composting bins to support practical learning.

Growing projects can also open conversations about seasonality, biodiversity, composting and reducing your school’s carbon footprint.

How can schools make healthy eating practical day to day?

For school business managers and leaders, healthy eating often comes down to making good routines easy to maintain.

Start by reviewing what already happens throughout the day. Look at breakfast provision, snacks, lunchtime, drinking water and after-school clubs rather than viewing each area separately.

Speak to catering teams, pupils, parents and staff about what works and where the barriers are.

It can also help to check whether staff have the practical resources needed to deliver the school's approach. Depending on your provision, this might include reusable water bottles, water jugs, drinking cups, food storage containers, chopping boards, food preparation equipment, serving utensils and cleaning supplies.

For curriculum activities, gardening equipment, plant pots, seeds, watering cans, growing trays, classroom nutrition resources and age-appropriate cooking equipment may also be useful.

The important thing is to start with the school's needs rather than the products. Resources should support a clear purpose, whether that is improving hydration, supporting food education or making practical activities easier to deliver.

What mistakes should schools avoid when promoting healthy eating?

One common mistake is treating healthy eating as something that only happens at lunchtime.

Children encounter food throughout the school day, so breakfast clubs, breaktimes, classroom activities, after-school clubs and school events should all be considered.

Schools should also avoid:

• creating a policy without involving pupils or families
• overlooking allergies or special dietary requirements
• relying on outdated nutrition advice
• providing inconsistent messages across the school
• making healthy eating unnecessarily complicated
• forgetting about drinking water
• assuming one approach will suit every pupil
• introducing activities without the right equipment, space or staff knowledge

Healthy eating works best when it becomes part of the wider school culture rather than a short-term initiative.

How can schools implement healthy eating successfully?

Start small and build from what is already working.

A practical approach could be:

• Review your current provision. Look across breakfast, snacks, lunch, drinks and after-school food.
• Check current guidance. Make sure food provision meets the relevant standards.
• Review your school food policy. Ensure responsibilities and expectations are clear.
• Talk to pupils and parents. Find out what they think about current provision.
• Check allergy arrangements. Make sure information and procedures are up to date.
• Make water accessible. Review drinking water stations and classroom routines.
• Build food education into learning. Use nutrition, cooking and growing activities where appropriate.
• Review your resources. Make sure staff have what they need to deliver activities safely.
• Link healthy eating with wider priorities. Consider physical activity, sustainability and pupil wellbeing.
• Review progress. Revisit the approach regularly rather than treating it as a one-off project.

Small, consistent improvements are usually easier for a school community to understand and maintain.

How does GLS support schools with healthy eating and food education?

GLS works with schools every day, so we understand that healthy eating involves much more than choosing what appears on a lunch menu.

Schools may be thinking about school catering, hydration, curriculum-based food education, practical cooking, growing activities or simply making everyday routines easier for staff and pupils.

GLS provides practical resources that can support these activities, including classroom nutrition resources such as the Eatwell Guide Floor Mat Bundle and Eatwell Guide Tabletop Activity, alongside catering, food preparation, hydration and gardening resources.

The focus should always be on what works for your school. A resource is useful when it helps staff deliver a clear educational or operational purpose — not simply because it is available.

Conclusion

Promoting healthy eating in schools does not require one big initiative. The most effective approach is usually a series of practical, consistent decisions across food provision, hydration, education and the wider school environment.

Review your school food policy, listen to pupils and parents, keep allergy procedures current and give staff the resources and knowledge they need. By working together, schools can create a positive food culture that helps children build healthier habits for the future.
