Understanding Children's Nutritional Needs
A child's nutritional requirements change significantly as they grow. This calculator uses USDA Dietary Reference Intakes (DRIs) and Estimated Energy Requirements (EERs) to provide age- and gender-specific recommendations.
Key Nutrients for Growing Children
- Calories: Fuel for growth, brain development, and daily activity. Requirements increase with age and activity level.
- Protein: Essential for muscle growth, immune function, and tissue repair. Children need 0.43-0.52 g per pound of body weight.
- Calcium: Critical for bone development. Children ages 9-18 need 1,300 mg daily -- more than adults.
- Iron: Supports oxygen transport and brain development. Teen girls need more due to menstruation.
- Vitamin D: Works with calcium for bone health. 600 IU daily is recommended for all children over age 1.
Daily Calorie Ranges by Age
- 1-3 years: 1,000-1,400 calories
- 4-8 years: 1,200-1,800 calories
- 9-13 years: 1,400-2,600 calories
- 14-17 years: 1,800-3,200 calories
Tips for Balanced Child Nutrition
