Plasma amino acid response to single test meals in humans. V. Ethiopian preschool children given lowcost protein supplements.
The plasma amino acid response to single test meals was studied in preschool children, aged 9 months--5 years. The amount of protein given in each test meal was 1 g per kg body weight, which represented one-third of the daily intake of the children who were recovering from protein-energy malnutrition. The test meals given was gruels made from wheat mixed with a supplementary weaning food (Faffa or Superamin) or fish protein concentrate (FPC). The plasma amino acid responses were evaluated both as PAA ratios (a modification of the Longenecker and Hause method), and as deltaMR% (percentage change in the postprandial essential amino acid molar ratios according to Graham and Placko). Both evaluation models indicated that lysine, threonine and methionine were the limiting amino acids in the Faffa/wheat diet, and that lysine and threonine were limiting in the Superamin/wheat diet. All essential amino acids seemed to be supplied in adequate amounts in the FPC/wheat diet. These results were in close agreement with the amino acid score of the diets (based on chemical analysis).
