What should be in a school lunchbox?

While healthier lunchboxes are not mandatory in the UK, many schools now encourage parents and carers to follow healthy lunchbox guidance as part of a wider whole-school food approach.

Typically aligned with the principles of the Eatwell Guide lunchboxes are encouraged to include a starchy carbohydrate food such as bread, rice, pasta or potatoes, alongside plenty of fruit and vegetables, a source of protein such as eggs, beans, pulses, fish or lean meat, and a healthy drink such as water or semi-skimmed milk.

Many schools also advise limiting foods high in fat, salt and free sugars, including crisps, confectionery and sugar-sweetened fizzy drinks. To help reinforce positive habits, some schools use non-food rewards such as stickers, certificates or team points to encourage healthier lunchbox choices. Collectively, these approaches aim to reinforce healthier eating behaviours and complement existing School Food Standards across the UK.

The “mix and match” lunchbox formula

One of the easiest strategies for busy households is to adopt a “mix and match” approach. Rather than reinventing lunch every day, keep a small selection of nutritious staples available and rotate them throughout the week.   

Having base foods such as:

• Wholemeal wraps, wholegrain crackers, mini bagels, oatcakes, plain popcorn, rice cakes.
• Cheese cubes, canned tuna, boiled eggs, Greek yoghurt, hummus, yoghurts/pouches.
• Apples, peaches, sliced grapes, cucumber, celery, peppers, carrots, celery (to slice), lemon (to prevent fruit browning) can make life much easier.

As advised by the Child Accident Prevention Trust foods such as whole grapes, strawberries, cherry tomatoes and large blueberries should always be prepared appropriately (for example, cut lengthways and into quarters).  Sausages, cheese and large hard fruit should be cut into thin strips.  Lunchbox foods should be prepared and tailored to a child’s age and eating ability. 

School lunchbox tips

Packing a healthy school lunchbox can feel like a daily challenge for many families.  The NHS Better Health, Better Families includes plenty of useful lunchbox recipes and tips. 

 

Some great take home tips include:

 

• Add salad to sandwiches and wraps too
• Add vegetables to the lunchbox where you can e.g. celery, carrot or cucumber sticks
• Always keep spare and different types of bread in the freezer
• Choose lower-fat cuts of meat, cream and hard cheese where you can
• Involved children with making their own wraps and sandwiches and adding their choice of fillings
• Low-fat and lower-sugar yoghurts are a nice lunchbox addition and fruit can be added
• Mix slices of bread – if children do not like wholegrain, try using 1 slice of white and 1 slice of brown
• Plain popcorn or rice cakes can be a useful swap instead of crisps
• Swap cakes, chocolate, cereals bars and biscuits for fruited teacakes, fruit breads, or fruit
• We have all been there – the fruit coming back home because it looks disgusting.  Add a squeeze of lemon to stop fruits from going brown.

Final thoughts

School lunchboxes do not need to become another source of stress for busy parents. By focusing on simple combinations, planning ahead and keeping nutritious staples readily available, it is entirely possible to create balanced lunches in just a few minutes.

Small, sustainable habits often have the greatest long-term impact. A sliced apple, a wholemeal wrap and a yogurt may seem simple, but together they provide valuable nourishment that helps children learn, grow and thrive throughout the school day. 

For families juggling packed schedules, the goal should not be perfection. It should be providing children with practical, enjoyable and nourishing meals that fit into real life.
