Packing school snacks that are filling, that your child will actually eat, and that fit your school’s allergy rules is harder than it sounds. Most schools ask families not to send nuts, which takes peanut butter, nut bars and trail mix off the list. This guide explains why schools are allergy aware, what makes a snack keep kids going until the next break, and shares a nut-free muffin recipe that freezes well.

At a glance

  • About 1 in 10 Australian one-year-olds has a food allergy, and around 3 in 100 have a peanut allergy (HealthNuts study).
  • National guidelines recommend schools be allergy aware rather than ban foods, but many schools still ask families not to pack nuts. Always follow your own school’s policy.
  • Discretionary foods make up 37% of the energy children aged 5 to 11 eat (ABS 2023).
  • Snacks with some protein or fibre, like yoghurt, cheese, eggs, roasted chickpeas or wholegrain baking, tend to keep kids fuller than chips or lollies.
  • Every child is different, and fussy eating, growth or allergies are worth talking through with a dietitian.

Why schools ask you not to pack nuts

Food allergy is common in Australian children. The Melbourne HealthNuts study found more than 10% of one-year-olds had a challenge-proven food allergy, including 3% with peanut allergy. In the follow-up SchoolNuts study of 10 to 14 year olds, about 2.7% had a peanut allergy and 2.3% a tree nut allergy.

The National Allergy Council’s best practice guidelines for schools recommend an allergy aware approach rather than food bans, and say that claiming to be “nut free” can give a false sense of security. In practice, many schools still ask families to leave nuts at home, and the guidelines point out that milk, egg, wheat and sesame allergies can be just as serious. Check your school’s policy for what is and is not allowed, including seeds and seed spreads.

What makes a snack filling for kids?

The Australian Bureau of Statistics found that in 2023, discretionary foods such as chips, biscuits, cakes and sweet drinks made up 37.3% of the energy eaten by children aged 5 to 11. These foods are easy to pack but tend not to hold kids for long.

Research in children is limited, but a review of protein-rich breakfasts in children and adolescents suggested they increased fullness and reduced later intake, although the studies were of low quality. In adults, a 2026 review found cereal fibre had favourable effects on fullness, though less effect on how much people went on to eat. A practical rule is to pair a fruit or vegetable with something that has protein or fibre.

Nut-free snack ideas

Ideas from the Cancer Council NSW Healthy Lunch Box examples and the five food groups:

  • Dairy: cheese cubes, a yoghurt pouch or tub (frozen, it doubles as an ice brick);
  • Protein: a boiled egg, hummus with vegetable sticks, roasted chickpeas or fava beans;
  • Wholegrains: wholegrain crackers, popcorn, homemade oat muffins or slices;
  • Fruit and vegetables: cut fruit, cherry tomatoes, cucumber or snow peas.

Read the labels on packaged foods, including the “may contain” statement, because some crackers, muesli bars and baked goods are made alongside nuts.
