Micronutrients: Iron, Zinc, and Calcium

31 October 2025

Micronutrients such as iron, zinc, and calcium play a vital role in a child’s growth, brain development, strong bones, and immune health.

When children don’t get enough of these nutrients, they may experience fatigue, poor concentration, low appetite, and become more prone to infections.

Zinc

Zinc supports a healthy immune system, helping the body fight off germs and recover from illness. Including zinc-rich foods in your child’s diet can reduce the risk of infections and support overall wellbeing.

Foods rich in zinc:

  • Wholegrain and wheatgerm bread

  • Red meat and poultry

  • Eggs

  • Legumes (chickpeas, lentils, beans)

  • Pumpkin seeds and cashew nuts

  • Plain popcorn


Iron

Iron is essential for both growth and brain function. It helps transport oxygen around the body and keeps energy levels stable. Low iron levels can cause tiredness, poor appetite, and weakened resistance to illness.

Foods rich in iron:

  • Wholemeal bread and fortified breakfast cereals

  • Pulses (beans, lentils, chickpeas)

  • Dried fruits such as apricots and raisins

  • Lean red meat

  • Leafy greens (spinach, kale)

  • Cashew nuts and almonds


Calcium

Calcium is key for building and maintaining strong bones and teeth. It also supports muscle function and helps regulate the heartbeat. Ensuring children get enough calcium early in life supports healthy development and can prevent bone weakness or fractures later on.

Foods rich in calcium:

  • Milk, yoghurt, and cheese

  • Custard

  • Tofu

  • Leafy greens (kale, spinach)

  • Sardines
