How fast can food pass through the body?

952 views

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?

I used to drink massive amounts of alcohol on a night out and the next day, everything I ate went straight through me due to having murdered my gut bacteria. Especially greasy food. Sometime not even an hour later it was already coming out the other end
