Diet containing dehulled adlay ameliorates hepatic steatosis, inflammation and insulin resistance in rats with non-alcoholic fatty liver disease.

Dietary modification plays a vital role in the treatment of non-alcoholic liver diseases. We investigated the effects of the consumption of a different amount of dehulled adlay, which has hypolipidaemic and anti-inflammatory properties, on non-alcoholic fatty liver disease (NAFLD). We fed rats a high-fat-high-fructose liquid diet for 16 weeks to induce NAFLD. The rats were divided into three groups fed the NAFLD diet only (NN) or a diet containing 44·9 or 89·8 g/l of dehulled adlay (NA and NB groups, respectively). After 8 weeks, the NA and NB groups had lower C-reactive protein levels and improvement in insulin resistance. In addition, the NB group had lower liver weight and hepatic TAG and cholesterol concentrations than did the NN group. Compared with the NN group, the high-dose NB group had improved steatosis, lower hepatic TNF-α, IL-1β and IL-6 levels and lower adipose leptin levels. Our results suggest that a diet containing dehulled adlay can ameliorate NAFLD progression by decreasing of insulin resistance, steatosis and inflammation.
