Evaluation of isoosmotic tube feeding formula in the diets of convalescent malnourished infants and children

WC MacLean Jr and GG Graham

The quality of the protein in a complete tube feeding formula intended for use in adults was evaluated in convalescent malnourished children. The casein-soy protein isolate blend was found to be similar to casein by comparative nitrogen balance studies carried out in five children, with protein providing 6.4% of calories. Three- and four-hour postprandial plasma free amino acid determinations at the same level of protein intake did not show the drop of plasma free methionine or of the methionine/total essential amino acid molar fraction characteristically seen when this amino acid is first limiting for protein synthesis. Three additional children were fed the formula, altered only by the addition of water, for periods of up to 3.6 months to test the tolerance to and completeness of the diet. No untoward effects nor signs of specific nutrient deficiency were encountered. Linear growth was appropriate for the stage of recuperation. The failure to achieve a normal (greater than 3.8 g/dl) serum albumin concentration in two of the three children may have been due to their rapid weight gain. Although it is intended for the adult, our results indicate that the formula could meet the nutritional requirements of infants and children.
