@EAGLE Veg is the natural food for humans. * Look at the teeth structure of non-veg animals and that of humans. * Vegitarians have long intenstines so also humans have. * Non-vegitarians generaly sleep at day and awake at night. Humans have opposite havits. * Humans dont have capacity to digest bacterias coming from non-veg foods (Bird flu, mad cow desease etc), but have capacity to digest desease coming from veg.
You can take the help of Biologists to confirm the natural foods for humans.
