I have had the feeling of eating beef and having to make a quick trip to the bathroom. It’s only certain cuts, which I imagine has something to do with the amount of fat in the food.
In Southern California, there is a famous restaurant called Lawry’s (it’s in other cities too) that serves cuts of prime rib that are usually big enough to feed a family of eight for a week. I had a small piece, but I still ended up in the bathroom before I left the restaurant. And there were two other men in the restroom with similar maladies.
This is not to say that the prime rib wasn’t good.
Heh. I have the same argument with my roommate. Chinese food, especially stirfry, usually forces me to the bathroom less than half an hour after eating it. And if it was particularly spicy…yeah, I feel it right away. I’ve had to stop eating at certain restaurants because it got so bad. But my roommate insists the same thing you do, that food can’t just fly through one’s system that quickly. Even so, I know what I eat and I know what happens when I eat it.
