Balanced Diet in Pediatrics

Definition

Principles of a Balanced Diet

The Food Guide Pyramid

• Bread, cereal, rice & pasta: 6-11 servings (base - largest intake)
• Vegetables: 3-5 servings
• Fruits: 2-4 servings
• Milk, yoghurt & cheese: 2-3 servings
• Meat, poultry, fish, eggs, dry beans & nuts: 2-3 servings
• Fats, oils & sweets: Use sparingly (top of pyramid)

Balanced Diet in Children - Age-Specific Guidelines

Infants (0-6 months)

• Exclusive breastfeeding for the first 6 months is recommended by both the WHO and the AAP
• Breast milk from a mother with a balanced diet satisfies all of the infant's nutritional requirements during this period - Medical Physiology
• Iron: Breastfed full-term infants need 1 mg/kg/day of elemental iron from iron-fortified cereals or meats from 4-6 months
• Vitamin D: All breastfed infants should receive 400 IU/day of supplemental vitamin D from within the first few days of life
• Fluoride: Infants 6 months - 3 years not on fluoridated water may receive 0.25 mg/day of supplemental fluoride

Infants (6-12 months) - Solid Food Introduction

• Single-ingredient foods should be introduced one at a time, for 1 week each, to observe for allergic reactions
• Single-grain cereals (e.g., rice) are usually well tolerated and provide iron
• Avoid honey in infants under 1 year (risk of botulism)
• Avoid popcorn, nuts, and rounded candies due to choking risk
• Wean from bottle to cup by 12-15 months; avoid bedtime bottles (associated with dental caries)

Toddlers & Preschool Children (1-5 years)

• Because young children cannot choose a well-balanced diet, parents must provide nutritious, safe, developmentally appropriate foods at regular meals and snacks - Textbook of Family Medicine
• Recommended dietary fibre: 19 g/day (ages 1-3 years); 25 g/day (ages 4-8 years)
• Small portions should be offered, allowing the child to determine how much to eat
• Children following strict vegetarian diets are at risk for deficiencies of Vitamin B12, Vitamin D, iron, calcium, and zinc
• Healthy children eating a varied diet usually do not require a multivitamin supplement
• Television and distractions should be avoided during mealtimes

Adolescents

• Energy needs: Sedentary girls: 1600-1800 kcal/day; sedentary boys: 1800-2200 kcal/day (add 200-400 kcal for active teens)
• Calcium: 1300 mg/day recommended (most teenagers fall short)
• Iron: Increased needs due to rapid lean body mass gain + menstrual losses in girls
• Zinc: Required for growth and sexual maturation
• Replacing milk with soft drinks, coffee, and tea lowers intake of calcium, vitamins A and C

Special Considerations

Key Takeaway

1. Age-appropriate in food texture, portion size, and nutrient density
2. Varied across all food groups
3. Supervised by parents/caregivers since young children cannot make dietary decisions independently
4. Supplemented where dietary gaps exist (especially vitamin D, iron, fluoride in infancy)
5. Adapted to special conditions (growth spurts, illness, vegetarian diet)
