I was a vegetarian for 14 years. I stopped when I was pg with dd #1 because I craved meat, and the cravings continued after dd was born. I still buy tofu, soy milk, other meat substitutes because I like them, too. I also like the taste of meat. In our area it's not difficult to get locally humanely raised meat. We have several rod and gun clubs and it's not too hard to get game meat, either.
I voted that it's the healthiest way for my family to eat. We usually spend the extra money to get local farm raised meat, organic hot dogs, etc.
I've asked dd if she would like to be a vegetarian, after she met vegetarians in her preschool. She said, no way, she likes hamburgers! I think it is the healthiest way for her to eat as well. She's very active, very skinny, and has a fast metabolism. She's also a picky eater. I have to get a complete protein in her in one fell swoop, plus a little extra fat. DD does not like soy or rice milk, veggie burger, etc (SHe will eat tofu pups). She loves dairy.
That all said, we don't eat large portions of meat, although we do have a little every day. We eat huge portions of veggies, a little bit of carbs, and a small portion of meat (fish, eggs, red meat, poultry)
I also think the poll is a little loaded. I do not think that vegetarianism is for everyone. You have to be very conscious of what you're eating, make sure you've got not just a protein source, but a complete protein source with all your amino acids. Not that it can't be done! And eating meat doesn't mean you're automatically eating a healthy diet. For me and for my family I've found a happy medium with a diet includes a wide variety of foods, including meat and vegetable based proteins.
I'm going to risk villifying myself and say that I do not think eating meat is inhumane. What is inhumane is the way animals raised on megafarms for meat are treated in life and death. When we sit down to eat, we thank and honor the animals and plants for giving their lives so that we may have a life-sustaining (and delicious) meal. When we die, we will become food to sustain plants and animals, and so the circle goes.
It is possible to eat meat ethically.
