Hello EA CO AS
Well I wasn't meaning to be gross - well just reallistcally honest & a bit funny- about the surprise the next morning. Lets face it, we're all humans, and we all have to do our thing in the bathroom.
Regarding your guess about large natural sugar content
, well, your guess is as good as mine. However, I do know (from my past schooling) that "large" CELLULOSE fibres cannot diffuse through the wall of the large intestines ..... thus the residue the next morning. The best example (that I can think of) of how the human body cannot digest a fruit or veggie's fibre is the onion.
If you want to teach little children about cells, peel one of the many thin layers that an onion has inside, put it under a microscope and drop some food colouring die on it.
It's a great way to actually see a living cell, and it's also to big for us Big Guys to digest.
