Daily Protein Requirements for Children

Age-Specific Recommendations

The European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) recommends an amino acid/protein intake of 1.0-2.0 g/kg per day for stable, healthy children aged 3-12 years, including 5-year-olds, with a strength of evidence based on clinical guidelines 1, 3

A healthy 5-year-old child requires 1.0-2.0 g/kg of body weight per day of protein, which translates to approximately 16-40 grams daily for a typical child weighing 16-20 kg, according to the Clinical Nutrition guidelines 1, 2
The Academy of Nutrition and Dietetics confirms that meta-analyses show no significant effect of dietary protein source on requirements, making both animal and plant proteins adequate for children's needs when consumed in sufficient amounts 2

For a 5-year-old who is critically ill and requiring parenteral nutrition, protein requirements increase substantially to approximately 2.8 g/kg per day to achieve positive nitrogen balance, as recommended by the Clinical Nutrition guidelines 1, 2, 3
For children with Chronic Kidney Disease (CKD) stages 3-5, the Kidney Disease Outcomes Quality Initiative (KDOQI) guidelines recommend 0.95-1.35 g/kg/day for ages 4-13 years (stage 3) and 0.95-1.15 g/kg/day (stages 4-5), assuming adequate energy intake 4

Do not exceed 2.5 g/kg/day in stable children, as there is no rational benefit beyond this level based on factorial approach analysis, according to the Clinical Nutrition guidelines 2, 3
