The effects of low dietary levels of polyunsaturates on alcohol-induced liver disease in rhesus monkeys.
Rhesus monkeys that were maintained on a diet containing low, yet adequate, amounts of vitamins C and E and in which linoleate and linolenate represented 1.4% and 0.08% of the total caloric intake, respectively, developed liver fibrosis after consuming alcohol (mean, 2.6 g kg(-1) d[-1]) over a period of 3 years. In the liver, several polyunsaturated fatty acids including 18:2n6, 20:4n6, and 22:6n3 decreased compared with dietary controls, and similar findings were also observed in plasma lipoproteins and erythrocytes. The amount of alcohol consumed correlated positively with plasma lipid peroxidation products, 4-hydroxynonenal (4-HNE) and 8-isoprostane F2alpha, and negatively with 20:4n6 and 22:6n3 levels. These findings imply that alcoholics who also have a marginal intake of essential fatty acids and antioxidants in their diets may be at an increased risk of developing liver disease.
