More children are dealing with digestive complaints — tummy pain, bloating, gas, constipation — that used to be far more common in adults. As a new school year gets underway, dietitian Caoimhe McDonald shares practical advice on building a lunchbox that’s balanced, gut-friendly, and still something your child actually wants to eat.
Digestive issues in children can have lots of causes, but everyday eating habits are often part of the picture. As Caoimhe explains: “The foods that children eat can have a profound effect on their health. Good nutrition supports a child’s immune system, brain function, growth and repair, and supports recovery from childhood illnesses, vaccinations and sports injuries. Influencing children at an early age to eat well is one of the most important things you can do for their health and well-being.”
Here are five simple, practical ways to make lunchboxes kinder on little tummies.
Good Nutrition Tips for School Lunches
#1. Water
Children aged 4–8 need around 1.6 litres of water a day. Swapping juice and cordial for a bottle of water in the lunchbox is one of the easiest ways to help your child stay hydrated through the school day.
Dehydration affects digestion directly — low water intake over time can lead to constipation and a build-up of toxins in the body, which raises the risk of more complicated digestive issues down the line.
#2. Say Hi to Fibre!
Most children don’t get enough fibre in their diet. Fibre — especially insoluble fibre — helps maintain the “friendly” bacteria in the gut that keep digestion regular and can relieve or prevent constipation.
Pack fibre-rich foods into the lunchbox where you can: pears and apples (skin on), berries, seeds, and wholegrain breads all help.
#3. Raw Vegetables
Raw vegetables hold on to more of their nutrients than cooked ones. Add raw veg to the lunchbox alongside a dip like hummus, which is also good for digestion.
For variety, swap the chickpeas in your hummus for black beans, broad beans, lentils, or soaked cashews. You can also make a white bean dip by blending a tin of cannellini beans with a garlic clove, chopped mint, chives, thyme, and a little olive oil.
Try folding some raw leafy greens into the hummus too — it’s an easy way to add live enzymes and count towards your child’s daily fruit and veg without them noticing.
#4. Have a (Protein) Ball!
Blend dried fruit, nuts, and peanut butter together for an easy protein ball, then dust with cocoa powder. It’s a low-fat, energy-boosting snack that’s a great addition to any lunchbox.
#5. Probiotics
A probiotic supplement can also help support a healthy gut. Not all supplements are equal, though — only a handful are backed by solid clinical evidence, so it’s worth doing a little research or asking a pharmacist before choosing one.
Frequently Asked Questions
Why is my child getting tummy aches at school?
Occasional stomach complaints in children are often linked to everyday factors like low water intake, not enough fibre, or a lunchbox heavy on processed snacks. Small changes to what’s packed each day can make a real difference for many children.
How much water should my child drink during the school day?
Children aged 4–8 need around 1.6 litres of water a day in total. Packing a water bottle instead of juice or cordial is a simple way to help them reach that through the school day.
What are good high-fibre foods to add to a lunchbox?
Fruit with the skin left on (like apples and pears), berries, seeds, and wholegrain bread are all easy, fibre-rich additions that support regular digestion.
Are probiotics worth adding to my child’s diet?
Probiotics can support gut health, but products vary widely in quality. Look for ones backed by clinical evidence, and check with a pharmacist or GP if you’re unsure which is suitable for your child.
Do dips like hummus actually help digestion?
Yes — hummus and similar bean-based dips are a good source of fibre and plant protein, both of which support healthy digestion, and they’re an easy way to get raw vegetables eaten too.
