Eating the Unknown

When children first begin to eat meat, do they realize that they are eating an animal? And whether they do or not, does this constitute as their first encounter (assuming they haven't encountered pets) with an animal? I doubt children are aware of what they are eating during there first few years. And therefore it might not be considered their first encounter with an animal, assuming their consciousness must play a role in the encounter. I'm not sure what implications any of this had, it is just something that came up.
When do people become aware of what they are eating? Because of being disattached from what we eat by having others kill, grow and prepare our food for us, many never know exactly what they are eating. We obviously become aware of foods, but much is prepared with ingredients we are not aware of. What we may call a chicken nugget is usually much more than a nugget of chicken. Of course many have also become aware of this, and wish to know what they put into their bodies, hence the movement towards organic foods, etc. This is a great reaction to chemically induced, mass produced foods, however, it is not always accessible and affordable. And I wonder whether it is necessary for everyone to adopt this way of eating. Organic foods are healthier, but many have survived quite easily without eating organic. And more than half of the world's human population is malnurished. Almost everyone of those persons would take any parcel of food available to them, organic or processed to shit. While I think people who can afford to shift their attention towards eating healthier, organic, etc. should do so, as one should take care of their own bodies first, I also think the world as an entirety should put more energy into feeding fellow humans. The two can be done simultaneously, but it is important that people eat before they eat as healthy as possible. Or not; maybe hunger and starvation has a necessary role in the cleansing of the overpopulation of humans on the planet.
