Protein Requirements by Age Calculator
Here’s a table outlining the protein requirements by age group based on general dietary guidelines:
Age Group | Protein Requirement (g/day) | Notes/Considerations |
---|---|---|
Infants (0-6 months) | 9.1 g | Protein primarily from breast milk or formula. |
Infants (7-12 months) | 11 g | As solid foods are introduced, protein from various sources becomes important. |
Toddlers (1-3 years) | 13 g | Growing children need protein for muscle and tissue development. |
Children (4-8 years) | 19 g | Protein is necessary for continued growth and development. |
Boys (9-13 years) | 34 g | Puberty starts, so protein needs increase for growth. |
Girls (9-13 years) | 34 g | Protein is needed for growth and development through puberty. |
Boys (14-18 years) | 52 g | Protein is important for muscle growth during adolescence. |
Girls (14-18 years) | 46 g | Protein supports growth, muscle mass, and hormonal changes during puberty. |
Adults (19-70 years) | 56 g (men), 46 g (women) | Protein supports overall health, muscle mass maintenance, and tissue repair. |
Pregnant Women | 71 g | Extra protein is needed for fetal development and tissue growth during pregnancy. |
Breastfeeding Women | 71 g | Protein supports lactation and postpartum recovery. |
Older Adults (70+ years) | 56 g (men), 46 g (women) | Protein needs may increase slightly to maintain muscle mass and support aging. |
Key Notes:
- Protein needs can vary depending on physical activity, health status, and specific conditions.
- Active individuals, athletes, and those with certain health conditions (e.g., recovery from illness or injury) may require higher protein intake.
