Good food
helps kids grow, learn, play and feel great. This concise, practical guide
explains the World Health Organisation’s (WHO) healthy diet principles for
school-age children (roughly ages 5–12) and translates them into everyday tips
that parents and children can use worldwide.
Why a balanced diet matters
A balanced
diet supports growth, brain development, immunity and school performance. It
also lowers the long-term risk of obesity, diabetes and heart disease. Around
the world, the double burden of too many children with overweight while others
remain undernourished makes healthy eating especially important. World Health

WHO basics: the simple rules
WHO’s
healthy-diet advice applies to people of all ages and is easy to adapt for
children:
- Plenty of vegetables and
fruit.
They’re full of vitamins, minerals and fibre; encourage a variety and
colourful plates. World
Health Organisation
- Choose whole grains and
legumes.
Brown rice, whole-grain bread, oats, beans and lentils give sustained
energy and nutrients. World
Health Organisation
- Eat moderate amounts of
healthy protein.
Fish, poultry, eggs, dairy, nuts and pulses are good sources: rotate them
through the week. World
Health Organisation
- Limit free sugars. Sugary drinks, sweets and
many packaged snacks should be occasional treats. WHO recommends keeping
sugars low (less than 10% of total energy, and lower is better). World
Health Organisation
- Reduce unhealthy fats and
avoid industrial trans-fats.
Aim for unsaturated fats (from fish, nuts, vegetable oils) and keep
saturated fats low. Industrial trans-fats should be avoided. World

Smart snacks & lunchbox ideas
Kids eat
several times a day snacks matter. Choose nutrient-dense options:
- Fresh fruit, sliced veggies
with hummus, yoghurt (plain or lightly sweetened), boiled eggs, nuts/seeds
(if allowed at school), whole-grain crackers, home-made chapati rolls with
veggies and lean protein.
- Avoid regular sugary drinks
and highly processed packaged snacks. Swap soda for water, diluted fruit
juice (small amounts) or milk. World

School & home: make them partners
Schools
have a huge influence. WHO recommends creating healthy school food environments,
healthy meal policies, limits on unhealthy foods sold at school, and food
education for children. Parents and schools working together make healthy
choices easier and normal for kids. World Health
Organization+1
Quick
actions parents can ask schools for:
- Balanced school meals with
fruits/veg and whole grains.
- Limits on sugary drinks and ultra-processed
snacks sold on campus.
- Nutrition lessons and hands-on
activities (gardening, cooking demos).
Dealing with picky eaters: realistic tips
- Offer new foods alongside
familiar favourites it can take many tries for a child to accept a taste.
- Make food fun: colourful
plates, small portions, and let kids help prepare simple recipes.
- Keep family mealtimes regular
and screen-free to encourage mindful eating.
- Praise trying, not just
finishing; avoid pressure or forcing.
Hydration and activity
Encourage
regular water drinking throughout the day. Combine healthy food with daily
physical activity play, sports, and walking to school, for overall health and
appetite regulation. WHO links healthy diets and active lifestyles to lower
long-term disease risk. World Health
Organisation
Cultural adaptation & affordability
WHO
guidance is flexible: use locally available foods and family recipes. Pulses,
seasonal fruits and vegetables, eggs and small fish are often affordable,
nutrient-dense options. Community food traditions can and should be part of
healthy eating. World Health

Quick “one-week” family checklist
- Include at least one vegetable
at every meal.
- Swap refined grains for whole
grains 3–5 times this week.
- Replace one sugary snack or
drink with a healthy alternative each day.
- Add a protein-rich food to one
meal a day (beans, eggs, dairy, fish, chicken).
- Go for one family activity
(walk, bike, game) together.
Final note
WHO’s
healthy-diet principles are simple, evidence-based and adaptable: more plants
and whole foods, less sugar and unhealthy fats, and supportive environments at
home and school. Small, consistent changes make a big difference to children’s
growth, learning and lifelong health. For the official WHO resources and deeper
guidance, see WHO’s healthy diet fact sheets and school nutrition policy
materials.
