To be pedantic- Fish is meat, meat is flesh, when you eat fish, you are eating its flesh=meat.

The human body does a good job of looking after itself to some extent, we wouldn't be alive and kicking today if we had to eat prunes each time we ate meat or we get colon cancer.

Come on, think about it, Humans have been eating meat longer than theyv'e been eating prunes, thats for sure.
