 | Protein-Energy Requirements of Developing Countries: Evaluation of New Data (UNU, 1981, 268 p.) |
 |  | Protein requirements-children |
| | Protein requirements of Filipino children 20 to 29 months old consuming local diets |
|
|
Conclusions and comments
- The mean protein requirement with this Philippine diet was 0.70 g/kg/day and the safe level of intake was 1.0 g/kg/day. All children had good nitrogen retentions with intakes of 150 mg nitrogen, or 0.94 9 protein/kg/day. All these values are lower than current FAD/WHO estimates and recommendations.
- Nitrogen absorption was low, probably due to indigestible proteins in rice.
- When protein intake is too low, dietary energy is not used very efficiently and weight gains are reduced
- Light infestations with A. Iumbricoides and T. trichiura did not affect dietary nitrogen utilization.
