According to geological records, the human came on the earth in the holocene epoch of the quaternary period of the cenozoic era. It may be about 2 million years ago that human first touched the land. About 10,000 years ago man used to derive his food by collecting edible parts of the naturally growing plants and trapping small animals. The habit of living in groups and hunting bigger animals in an organised way was developed later on. The next stage in the civilisation was the beginning of organised agriculture.

Various structures in the human body support the idea that a vegetarian diet is the best for human beings. The structures are, large number of grinding teeth, big size with large internal surface of small intestine, secretion of digestive juices in large amount, need of ample roughage numerous tasts buds in tongue, etc. The strong digestive power necessary to digest a vegetarian diet is a gift of nature.
