It gets expelled each day as bile.

Yes, it rots in your colon, that is exactly right. If you eat a diet with a lot of fiber and fresh fruits and vegetables, more of the undigested meat will pass through your system. However , the human digestive system is incapable of completely digesting red meat.

No, it does not "rot" and those nutballs who claim that "everyone has five pounds of undigested red meat in their colon" have never taken a biology course.

Silly scare tactics trying to force their lifestyle on you.

It rots.

And then there's the corn issue. Corn hangs around in there and causes a bottleneck sometimes. If you ever need a colonoscopy there's a good change the doctor will find some kernels of corn lurking around in your colon. One doctor told me he finds at least 3-4 every single time.

No, contrary to what some previous posters say, meat is digested in your stomach. The remains travel through your intestines and through the colon and um, outward.

Think about it. Have you ever crapped out a piece of steak, or a piece of chicken? I'm 47 and I never have.

On the other hand, peas and corn never get fully digested, do they? Believe you me, between metamucil and my diet, I get more than the recommended dose of fiber.
