Nutritional model of steatohepatitis and metabolic syndrome in the Ossabaw miniature swine.

ABSTRACT:

Unlabelled

Miniature pigs residing in the Ossabaw Island (Ossabaw pigs) exhibit a thrifty genotype, and when fed a high-calorie diet they consistently develop metabolic syndrome defined by obesity, insulin resistance, hypertension, and dyslipidemia. We conducted a study to induce steatohepatitis in Ossabaw pigs by dietary manipulation. Pigs were fed standard chow (controls, n = 15), high-fructose diet (20% kcal from fructose and 10.5% kcal from fat) (fructose group, n = 9), atherogenic diet (20% kcal from fructose and 46% kcal from fat and 2% cholesterol and 0.7% cholate by weight) (atherogenic diet group, n = 13), and modified atherogenic diet (different source of fat and higher protein but lower choline content) (M-Ath diet group, n = 7). All animals were sacrificed at 24 weeks a
