Abstract
Nitrogen, fat and caloric retention were measured in 10 male infants recovering from marasmic malnutrition when fed either LP or LPM. Subjects were 6.8 months old on average and had a W/A ratio of 72% and a W/H ratio of 95% of the NCHS standard. They went through two consecutive balance periods of 6 days each (3 days for adaptation and 3 days for urine and feces collection). Caloric density of both formulas was 85 Kcal/100 ml with 13% of calories from protein in LP and 11% in LPM. Caloric intake, absorption and relative retention was slightly and not significantly greater with LPM than LP. Fat intake was greater with IPM (5.4 gr/kg/day) than with LP (4.2 gr/kg/dia) (p<0.025). This resulted in significative differences in fat absorption (LPM: 4.3 gr/kg/day; LPM: 3 gr/kg day, p<0.0025). Nitrogen intake was significantly less with LPM (487 mgAg/day) than with LP (571 mgAg/day) (p <0.0025) with a greater urinary nitrogen excretion for LP (417 mgAg/day) than for LPM (304 mg/g/day) (p<0.001). Aparent nitrogen retention for LPM was on average 115 mg/kg/day and for LP only 68 mgAg/day. This difference was not significative because wide individual variation. Over the short period of the study no difference was detected in biochemical or anttrrcpometric indicators of nutritional related to the feeding of LP or LPM.
