Improved liver phenotype in mice fed a diet supplemented with green tea. Liver weights after 11 (A) and 22 (B) weeks on the different diets. Triacylglycerol (TAG) content in liver after 11 (C) and 22 (D) weeks, respectively. The concentration of the liver enzyme ALT measured in plasma after 11 (E) and 22 (F) weeks. Ctrl = high fat control diet (HFD), Lp = HFD + L. plantarum in the drinking water, GT = HFD supplemented with 4% green tea powder, Lp + GT = HFD supplemented with 4% green tea powder and L. plantarum in the drinking water. Data are means ± SEM for n = 21 at 11 weeks and n = 9–11 at 22 weeks. *p < 0.05, **p < 0.01, ***p < 0.001.
