I have read somewhere that it is normal to defecate about once a day. This leads me to think that it takes about 24h for food to pass through the body under normal circumstances.
Now lets say you eat some bad sushi that triggers “the runs” within an hour.
When you then defecate, is it the actual sushi that comes out or is it just the food you ate before the sushi?
Also, how fast could food theoretically go from mouth to anus?

Depends on whether you ate something that disagrees with you. If your body thinks you’ve ingested poison, you’re going to flush everything out as soon as possible. It takes about 6 hours for food to hit your large intestine, but then if your guts want it out, they can just speed it along in liquid form. You absorb essentially no nutrients from it if that happens. So minimum about 5 hours.
