Beneficial Effect of a Low Dose of Ethanol on Liver Function and Serum Urate in Rats Fed a High-Fat Diet

Abstract

This study investigated the effects of the consumption of 1% or 2% (v/v) ethanol in drinking water for 12 wk on rats fed a high-fat diet. Body weight gain, food intake, and fluid intake were unaffected by ethanol intake. Adipose tissue weight, and serum glucose and lipids were unaffected. Compared to the control (no ethanol), 1% ethanol intake significantly reduced serum levels of alanine aminotransferase (ALT), lactate dehydrogenase (LDH), and ammonia (p<0.05), whereas 2% ethanol intake did so to a lesser extent. Serum urate was significantly lower in both the 1% and 2% ethanol groups than that in the control group (p<0.05). The results suggest a low dose of ethanol has beneficial effects on liver function and serum urate in rats fed a high-fat diet.
