Ameliorative effects of lutein on non-alcoholic fatty liver disease in rats

Figure 6 Lutein’s effect on fasting glucose (A), fasting insulin (B), HOMA-IR (C), and HOMA-β (D) in rats fed a high-fat diet. After the 45-d lutein intervention, fasting glucose was tested as described and fasting insulin was measured using an insulin ELIZA kit following the manufacturer’s instructions. HOMA-IR = FIN × FPG/22.5, HOMA-β = 20 × FIN/(FPG-3.5). ^aP < 0.05, ^bP < 0.01 vs the normal diet (ND) group, ^cP < 0.05, ^dP < 0.01 vs high-fat diet (HFD) group. Data are expressed as the mean ± SD (n = 8).
