Background: Hyperlipidemia is one of the most challenging clinical disorders and is known to be a causative factor in a number of related conditions. Garlic has traditionally been used to lower serum lipids in hyperlipidemia patients. The present study evaluates the renoprotective role of garlic against induced changes in rat kidneys as a result of a high-fat diet (HFD). Materials and Methods: Twenty adult male Wistar rats were arranged into 4 groups: Group 1 (control) were fed a normal rat diet; Group 2 were fed an HFD (butter in a dose of 20g/100g food); Group 3 were fed fresh garlic juice (GJ) in their diet (6g/100g food); and Group 4 were fed with butter and GJ in their diet (HFD + GJ). The experimental period was 8 weeks. Serum lipid profiles and renal function tests were carried out and evaluated. Results: The HFD significantly increased body weight, total serum cholesterol, triglycerides, low-density lipoprotein cholesterol (LDL-C), uric acid, creatinine, and blood urea nitrogen (BUN), and decreased total protein and albumin, as compared to the control. In the HFD + GJ group, normal body weight was restored; serum levels of total cholesterol, creatinine, BUN, and albumin were similar to the control, and serum levels of triglyceride, LDL-C, uric acid, and total protein were partially restored to the levels of the control. Conclusions: The incorporation of GJ into an HFD resulted in improved lipid profile and kidney function. Hence, the consumption of GJ may be a useful supplement for renal protection in hyperlipidemic patients.
