How can certain foods pass straight through you when your intestines already have digesting food in them from previous meals blocking the path?

Question

It takes ~36 hours from the moment you bite into your meal to when you’re pooping it out. Meaning, your digestive tract has 36 hours worth of meals it’s currently digesting at any given time.

When you eat something bad, it seems that you’re on the toilet pooping it out within the hour. How is that even possible if the pathway is blocked by 36 hours worth of meals?

Answer 1

I’m curious about this 36 hours business. I can eat something, say something fibrous that will stand out like corn or oranges or soemthing (something you can tell what it is when it comes out), and I see that back in the toilet at least within 8 hours, usually faster than that.
