School-age children between 5 and 12 years are in a sustained period of physical and cognitive development. Their nutritional needs per kilogram of body weight are higher than adults, yet this is precisely the life stage when many families struggle most to provide consistent, quality nutrition.
The three most critical nutrients for school-age children are iron, zinc, and calcium. Iron supports brain oxygen supply and directly impacts a child's ability to concentrate and learn. Zinc strengthens immunity and supports appetite. Calcium builds the skeletal foundation that will determine bone strength for life.
"A practical approach: children need 3 meals and 2 snacks daily. Breakfast is the most important — children who eat a nut..."
Variety matters. Encourage children to eat across all food groups: grains and cereals, legumes, vegetables, fruits, and small amounts of animal protein when available. The more colours on the plate, the more complete the micronutrient profile.
Hydration is often overlooked. Children should drink water throughout the day, especially during school hours. Even mild dehydration — 1–2% of body weight — impairs cognitive performance and mood.
