Figure 5

Dietary cinnamaldehyde boosted in intestinal healthy. The intestinal histopathology for hematoxylin–eosin (H&E) staining: (A) CNE0 group; (B) CNE200 group; (C) CNE400 group; (D) CNE600 group; (E) CNE800 group; and (F) CNE1000 group. The arrows in the figure indicate damage to the intestinal villi, intestinal wall sites. Red arrows: intestinal villi; black arrows: intervillous space.
