Abstract

Three different groups of infants were fed with different formulae based on milk fat. Group I received cow's milk fat formulae with 20% butter fat whereas groups II and III received a formulae which was supplemented with 50 and 33% of peanut oil supplementation in 20% milk fat respectively. Anthropometric measurements, cholesterol, triglyceride, lipoproteins and plasma fatty acids were followed up to a period of 6 months. The results indicated that cow's milk-fed infants had higher cholesterol levels (P < 0.01) than the other two groups. No significant differences with respect to high-density lipoproteins (HDLs) were found, whereas low-density lipoproteins (LDLs) and very low-density lipoproteins (VLDls (VLDls) were found to be increasing up to a period of 6 months. No significant differences were observed with respect to saturated fatty acids and oleic acid (18:1) levels whereas linoleic acid (18:2) clearly showed a proportional relationship between the intake and plasma levels, indicating a positive correlation. Arachidonic acid (20:4) did not, however, show a proprotionate relationship with respect to linoleic acid (18:2) intake. The triene/tetraene, oleic/linoleic, linoleic/arachidonic and total n6 fatty acids were all normal indicating normal activity of desaturase and elongase enzymes for the optimal utilisation of linoleic acid. Thus, the present study suggests that a vegetable oil such as peanut oil could be used in milk fat to improve the essential fatty acid (EFA) status of infants.
