title: The nutritional value of oat flour for very young children.
abstract: Whole groat flour was consumed by nine infants and young children as 22.5, 45, or 67% of total diet energy (one half of 6.4%, all of 6.4%, or all of 9.6% protein energy). Isonitrogenous and isoenergetic casein control diets were given. Apparent absorption of oat nitrogen (N) was consistently around 75% of intake (casein, 87%), but absorptions of oat energy, carbohydrate, and fat, as percentages of intake, decreased disproportionately as oat flour intake was doubled and then tripled. Apparent retentions were 39 +/- 5% of mixed oat-casein protein intake in the 22.5% diet, the preceding and following casein controls being 38 +/- 8% (NS) and 44.4% (p less than 0.05) of the intakes; 32 +/- 6% from oats in the 45% diet, controls 38 +/- 5 and 46 +/- 5% (both p less than 0.05), and 33 +/- 11% from oats in the 67% diet, controls, 36 +/- 9% (NS). Fasting plasma free total essential amino acid (TEAA) levels of children consuming 45% oats were low (562 +/- 119 mumol of TEAA/L) and did not change significantly after meals. Fasting molar proportions of individual essentials (millimoles of EAA per mole of TEAA) were similar to those from milk protein diets and did not vary significantly 3 and 4 h after feeding, suggesting that no individual amino acid, but rather protein digestibility, was first limiting to N retention. Oats are a satisfactory source of energy, protein, and fat for very young children and many infants.
