Conclusions

  1. With the diet used in this study, protein intakes were adequate when energy intakes corresponded to the estimates of energy requirements.
  2. The protein and energy needs of well-nourished children were satisfied by the diets used in this study if:

(a) dietary energy density was increased, and
(b) sufficient amounts of the staple foods were available.

  1. If the diet is supplemented with foods of animal origin or other high-quality proteins, there is no need to provide them every day of the week. Some local vegetable based diets may not require such supplements.
  2. It is not necessary to change the composition of the diet during short, acute episodes of disease or during convalescence from them if the foods are offered to the child in sufficient amounts to satisfy his appetite.
  3. The energy needs of most well-nourished children two to four years old can be satisfied with dietary intakes of 92 to 95 kcal/kg/day.
  4. Measurements made at 4-day intervals over 28 days yield good metabolic-balance data. A 28-day period of observation is adequate to assess the dietary effects on body weight and metabolic balance if the child does not become ill. In that event, other 28-day replications are necessary. The evaluation of other anthropometric changes requires a longer time.
  5. It is still necessary to show whether or not the preceding conclusions are correct for pre-schoolers with mild-to-moderate protein-energy deficiencies.
