Abstract
Crude oil contaminated diet has been reported to induced changes in lipid profile of rats. In this study, 60 albino rats in 6 groups were fed with crude oil contaminated sugar-garri diets at varied concentrations to monitor petroleum-induce lipid profile changes using standard methods. The lipid profiles estimated were total cholesterols, triglycerides, high density lipoprotein cholesterol and Low density lipoproteincholesterol.The data showed that, the levels of total cholesterol (Mmol/l) increased from 2.89+0.08 in sugar fed rats compared with 3.05+0.12 in Gari fed rats. The concentration of triglycerides(Mmol/l) reduced from 1.10+0.51 in sugar fed rats to 1.06 + 0.03 in Gari fed rats while the high density lipoprotein cholesterol(Mmol/l) concentration of 2. 01+0.08 was significantly higher than 1.89 + 0.03 in Gari fed rats (P<0.05).There was no significant difference in Low density lipoprotein cholesterol (Mmol/l) concentrations of 0.68+0.11 in sugar fed rats compared with 0.83 + 0.10 in Gari fed rats. The effect of pre-treatment of the diet with sugar reduced petroleum-induce changes in lipid profile than gari during the exposure of the albino rats to the petroleum diet suggesting that sugarcould possibly ameliorate petroleum-induce changes in lipid profile as shown by the significantlowering of the cholesterol and Low density lipoprotein cholesterol than gari in albino rats.

Highlights
The aim of this paper was to compare possible protective roles of sugar and gari diets against petroleum induced changes in lipids using cholesterol, triglycerides, high density lipoprotein cholesterol and Low density lipoproteincholesterol as indicators
Achuba (2005) had reported that feeding rabbits with diets containing various concentrations of crude petroleum caused significant dose related increases in cholesterol suggesting that ingestion of petroleum contaminated diet could predispose humans to cardiovascular diseases while the result of this study has shown that sugar diet reduced cholesterol concentration more than gari diet
The LDL cholesterol (Mmol/L) of 0.83 + 0.10 in gari treated rats was significantly different from 0.68 + 0.11 in sugar treated rats as shown below in table 3.Braideet al., (2013) in their study reported that ingestion of petroleum contaminated diet caused increase cholesterol and LDL cholesterol and decreased triglycerides and HDL cholesterol while feeding on gari diet caused reversed to changes in lipid concentration caused by crude petroleum
Summary
The aim of this paper was to compare possible protective roles of sugar and gari diets against petroleum induced changes in lipids using cholesterol, triglycerides, high density lipoprotein cholesterol and Low density lipoproteincholesterol as indicators. The Cholesterol concentration (Mmol/L) of the control in gari treated albino rats was 2.62 +0.17. Achuba (2005) had reported that feeding rabbits with diets containing various concentrations of crude petroleum caused significant dose related increases in cholesterol suggesting that ingestion of petroleum contaminated diet could predispose humans to cardiovascular diseases while the result of this study has shown that sugar diet reduced cholesterol concentration more than gari diet.
