How fast can food pass through the body?

Question

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?

The first time my brother had Indian food it took him about 10 minutes after we finished the meal and were driving home. He said “drive faster” and it was a photo finish in the 5 minutes it took me to get home. He is lactose intolerant, but it has never stopped him from eating dairy as much as he wants.
