10.1 MEANING AND CONCEPT OF DIET

Diet is the total amount of the food taken by individuals or any other organisms
for their survival. Usually diet is referred as a ‘blend of specific nutritional food’
taken by a person for good health or weight management. We, the human beings
are omnivores and due to diverse culture and society, each of us has different
food preferences or food habits.
Note
Food choices and habits play a crucial role in determination of health and
durability of the individuals. Food is important for life. We require food for our
survival and we cannot survive for a long period without food. Therefore, proper
intake of food is necessary for all living beings. The food can be anything that
we eat to satisfy our hunger. It comprises solids, semi-solids and liquid. Food
also nourishes our body.

For obtaining quality of life, we should certainly have proper food intake. The
foods we eat should also be safe and rich with all the nutrients that our body
needs. Try to have a wide variety of foods in your diet and eat them on regular
basis. It is also important that we should enjoy food while eating; the food should
look, smell and taste good. Without nutritious food, no one can optimise his/her
potential to the full extent, as well as adults will face difficulty in doing their
best.

Diet is the sum of the food consumed by us for our survival. It refers
to the use of specific intake of nutrition for health or weight
management. Proper and timely intake of it is essential because it
contains substances which perform important functions in our body.
