Effect of some dietary animal and plant protein on the lipid profile in hyperlipidemic rats

ABSTRACT

The present study evaluates the effect of some dietary animal and plant protein on the hp1d profile m experimental animals'. Sixty· four adult male albino rats of Sprague Dawely strain weighing [160+/- 8.4 g] were divided into eight groups every group contain 8 rats. The first group served as negative control, fed on standard diet. The second group served as positive control, fed on hyperlipidemic diet contain 10% level casein. Moreover, the remaining 6 groups fed on hyperlipidemic diet at 10%, level of, protein obtained from the following protein sources whey; soy; meat; [meat protein + whey protein, 11]; [meat protein+ soy protein, 11] and [meat protein+ soy protein +Whey protein, 1 1 1 ]. The result revealed that serum total lipids of all groups were significantly lowered [PS 0.01] except group fed on meat, serum Total cholesterol; triglycerides; low density lipoprotein [LDL-C] and high density lipoprotein cholesterol [HDL-C] of all groups were significantly reduced [PS 0.01] as compared with positive control group. Fecal excretion of neutral steroids of all groups were significantly elevated [P S 0.01] except the group fed on mixture of [meat protein+ soy protein +Whey protein] as compared with positive control group
