Respect for the lives of animals including cattle, diet in Hinduism and vegetarianism in India are based on the Hindu ethics. The Hindu ethics are driven by the core concept of Ahimsa, i.e. non-violence towards all beings, as mentioned in the Chandogya Upanishad (~ 800 BCE).. By mid 1st millennium BCE, all three major religions – Buddhism, Hinduism, and Jainism were championing non-violence as an ethical value, and something that impacted one's rebirth. According to Harris, by about 200 CE, food and feasting on animal slaughter were widely considered as a form of violence against life forms, and became a religious and social taboo. India, which has 79.80% Hindu population as of (2011 census), had the lowest rate of meat consumption in the world according to the 2007 UN FAO statistics, and India has more vegetarians than the rest of the world put together.
