We the people know that our first requirement is food without which we cannot last long, not even we can perform our daily inborn activities. Not we only, but also the other animals of the whole world need this basic thing to maintain their required energy. But one thing must have to be kept in our knowledge that the other animals and creatures except the human being can not (develop/upgrade/improve) the food habits and also the selection of food items. We, the human beings are very much conscious about our food system, because of the fact that it can contribute to both of our physical and mental life.

The food system differs among the human being in terms of region, climate, weather, natural resources etc. Even in the same country people of different states or regions are seen to use different practices of food. As for example, the food system of the people of Thailand is not exactly same with food system of the people of India. This difference may be mainly due to the climatic differences.

Among the birds, we observe that the mother birds collect food and coming back to their nests, they use to feed their small babies. Likewise among the human being, the mothers have to feed their own milk to their children. After taking a lot of months, the small babies are allowed to have ‘rice’ or ‘roti’ in presence of the invitees gathered in the ‘Annaprashana’ ceremony.
