There are wet wipes that are accepted and toilet friendly because of their ability to disintegrate once it gets flushed and goes down through the sewer system.

Then, there are wet wipes that are not so toilet friendly. They do not disintegrate once flushed down and floating about through the sewer system. They end up clogging the pipes over time.

It's literally the same with fresh food versus heavily processed food once it enters your gut. Fresh food rots. So it's easy to break down in your gut. Processed food not so much. It's like the non toilet friendly wet wipes.
