Children and their protein requirements
An adequate intake of protein containing all the essential amino acids is crucial for optimal growth and development in children.
In addition to protein's fundamental structural role in cells, antibodies, enzymes and many hormones, it may also assist in improving satiety.
Protein occurs in all living cells and has both functional and structural properties. Amino acids, assembled in long chains, are the building blocks of protein. Amino acids are used for the synthesis of body proteins and other metabolites and can also be used as a source of dietary energy. The proteins of the body are continually being broken down and resynthesised in a process called protein turnover.
Recommended intakes of protein for children take into account maintenance as well as growth demands.
Age RDI (grams/day)
1-3 yrs 14 gram/day (1.08 gram per kg)
4-8 yrs 20 gram/day (0.91 gram per kg)
Boys
9-13yrs 40gram/day (0.94 gram per kg)
14-18 yrs 65 gram/day (0.99 gram per kg)
Girls
9-13 yrs 35gram/day (0.87 gram per kg)
14-18 yrs 45 gram/day (0.77 gram per kg)
A child's protein requirements can usually be adequately met through diet (including meat, chicken, fish, nuts, eggs, and other dairy products). However when nutrient requirements increase, such as after illness or as a result of poor eating habits, then it could help to provide a little extra protein via whey powder.
