Healthy eating gives your child energy to play, grow and learn

Start each day with a healthy breakfast

This helps your child to focus. Healthy options include porridge, low-sugar wholegrain cereal, eggs, wholegrain toast, rice, veggies, fruit and yoghurt.

Offer a variety of foods from the 5 food groups

To support good health, include plenty of vegetables, fruit, cereals and grain foods, dairy or plant-based alternatives with added calcium, and meat, chicken, fish, seafood, eggs, beans/legumes, nuts and seeds.

Offer healthy snacks

Healthy snacks can give kids energy between meals. Try fruit, veggies, nuts, yoghurt or wholegrain bread/crackers and cheese.

Drink plenty of water each day

Water is the best drink for growing minds and bodies. It also helps keep teeth and gums healthy.

Eat together when you can

Sharing and cooking meals together encourages kids to try different healthy foods. It’s also a great way to spend time as a family.

Brush teeth in the morning and before bed

Healthy teeth and gums help us smile, speak, eat and socialise.

Movement and sleep help with health, mood and focus
