Please make my day suck less after reading this in a "sidenote" in my microbiology textbook:

"The higher the fat
content of food, the
slower the movement
of feces through
the bowels, where
bacteria convert
the undigested fats
into cancer-causing

I rolled my eyes so hardcore, but I'd like it if anyone could come up with some convoluted reason why any textbook author would ever think this to be accurate.
