K. Hariharan et Pl. Raina, INFLUENCE OF LONG-TERM FEEDING OF PALM OIL ON THE LIPID-COMPOSITION OF PERIRENAL ADIPOSE-TISSUE IN RATS, Die Nahrung, 37(4), 1993, pp. 374-379
The composition of perirenal adipose tissue in Wistar strain of rats f
ed palm oil (PO) fat at 5% and 20% in diet for a period of 18 weeks wa
s studied. Peanut oil (PNO) at 5% and 20% were used as controls. Under
the experimental conditions, the saturation index was higher in anima
ls fed diet containing PO compared to those fed PNO. There was no sign
ificant difference with reference to 12:0, 14:0 and 18:1 fatty acid le
vels, whereas linoleic acid (18:2) showed a proportional relationship
between the intake and perirenal adipose tissue levels. There was a si
gnificant correlation of dietary intake of linoleic acid and the U/S r
atio in the adipose tissue. Linoleic acid (18:2, n6) levels were incre
ased in 20% PNO groups as compared to those fed PO. However, palmitole
ic acid (16:1) did not show a proportional relationship between the in
take and adipose tissue levels. Thus, our studies show that more satur
ated fatty acids are incorporated in the PO group than in the PNO grou
ps at the end of 18 weeks feeding.
