My diet is pretty relevent to this discussion. After my parents divorced my mother stopped doing things like making me eat things I didn't like or brushing my teeth. I now have horrendous teeth and like almost no food. Literally the only vegetables I somewhat like are potatos, peas and maybe carrots if they are cooked a certain way. I eat almost exclusively meat and junk. (being Australian and hating onions doesn't help, it's in literally EVERYTHING. Can't even buy mac and cheese without onion in it for whatever insane reason.) Let kids have their way and they'll ruin themselves. I also feel like giving them something they hate so much will help them appreciate other things and perhaps even things they might not have liked that much to begin with.
