FOS and steatosis: According to the NAS, steatosis (MSG, 1.7 ± 0.4; MSG + FOS, 0.3 ± 0.4; p = 0.001), lobular inflammation (MSG, 1.0 ± 0.3; MSG + FOS, 0.2 ± 0.1; p = 0.001) and ballooning degeneration (MSG, 1.7 ± 0.4; MSG + FOS, 0.3 ± 0.4; p = 0.001) were less severe in the MSG + FOS mice compared with the MSG mice (Fig. 2b).
