Reply to comment by JeffroDH in ELI5: If food takes 6-8 hours to fully digest and make it to the small intestine, how come food you eat now affects the qualities of feces from food eaten 8 hours ago (i.e. having to use the toilet soon after eating)? by [deleted]
Yes, and it is unlikely that what you are 8 hrs prior is making it's way out of you. After the small intestine is the large intestine, and then you can poop it out. Gut motility varies from person to person, and "normal" can be anywhere from 16 hrs - 2 days to get through your system.
Curious how long yours is? Eat corn and see when it passes. Or eat a bunch of beets and wait till you see purpleish-red poop!
