Abstract
This study was designed to investigate the effect on treatments of garlic and the improvement of lipids in dietary-induced hyperlipidemic rats. Rats were administrated 1% cholesterol to induce hyperlipidemia and were fed diets containing fresh garlic powder (FGP), steamed garlic powder (SGP) and black garlic powder (BGP) by 3% (w/w) for 4 weeks. Body weight gain and food efficiency was not significantly different between control and garlic powder fed groups. Liver weight was significantly higher in control and SGP fed groups. Blood glucose was decreased in FGP and BGP fed groups than control group. The concentration of total lipid was significantly decreased in BGP group. Total cholesterol and triglyceride of serum were significantly lower in garlic powder fed groups than control group. HDL-cholesterol was significantly higher, LDL-, and VLDL-cholesterol were significantly lower in the garlic powder fed groups than the control group. Activities of serum GOT was lower in SGP fed group than control group. Total hepatic lipid and cholesterol concentration were conspicuously decreased by garlic powder fed groups. TBARS concentration of liver was significant different for the added garlic powder administration. Antioxidant activity of liver tended to increase in garlic powder fed groups compared with control group. In this result, we suggest the preventive effect of black garlic against the atherosclerotic process and the improvement of hyperlipidemia through the removal of cholesterol.
