I never much liked meat or chicken or milk or eggs - even as a baby - but ate it reluctantly until about age 22 (I'm 43 now). I gave up fish a few years after that, when I got scared of contaminated water, overfishing, and mercury levels. I've been off and on dairy and eggs through the years, more of a digestive issue than a moral one. For the last few months I've been CRAVING sardines and salmon, and no vegetarian substitute or seaweed would do. I finally gave in and had some sardines and salmon the last 3 days and I FEEL WONDERFUL. I guess it pays to listen to your body as much as listen to the experts.

Thanks to all of the posters above for helping allay the fear that I'd get horribly sick in some way. I still doubt I'll eat meat or chicken, so you can have my serving of bacon....
