Your implication is that nothing should ever be suggested without scientific references and footnotes. That is just absurd in the extreme. Do you do search the journals before teaching your kid to wipe his ass? Do you really think that diet is any different from any other thing that we do several times a day for our entire lives?

The number of people making fantastical claims about toilet paper is a lot smaller than the number of people making fantastical claims about the important of specific diet components or habits.

Like take your comment that I replied to. It is incredibly specific advice. As if there is 1 brand of toilet paper that is absolutely the right one.

I think it would be more like, use soft toilet paper and wet it to avoid overwiping. It's a good guideline but not a physical law etched in stone.

Or follow the more enlightened civilization and use bidet.

Or -- to get this back on topic -- add more fibre to your diet and your days of messy wiping will be over [1].
