Some Important Points about Food
We eat different parts of different plants.
Lot of people near the rivers or seas depend heavily on fish, crabs and other sea animals for food.
The quality of food that we eat does not depend on its source-plants or animals-but on its composition. Our food should have things that can provide energy, in our body, help us grow and keep us healthy.
Water is also a very important part of our food.
People at different places do not get all kinds of food. They eat whatever is available in their place. It is best to eat locally available food because they will be fresh.
All kinds of food cannot be eaten raw, some of them have to be cooked. Cooking makes the food tasty, digestible, and easy to eat and kills the disease causing germs present in it.
Different spices, oils and methods of cooking in different places (and families) make the food taste different. The taste for a kind of food is not the same for all of us.
Food must be eaten fresh. It should neither be very warm nor cold. It should also consist of all the types of nutrients required by us.
