Importance of food in life

Food is the only source of vital energy for the body. Our body functions by utilizing the energy from food. Food acts as fuel to generate energy in the mitochondria. Glucose from the food interacts with the oxygen we breathe. This leads to a process called oxidative phosphorylation which generate energy in the form of ATP. Carbon dioxide and water molecules are formed as bye products of the above mechanism.
2. For body shape and form

Drugs act well when taken with sufficient food. Food gives strength to the body to accommodate a drug safely and also metabolize it after its action in the body.
Without food, drugs fail to overcome some diseases like tuberculosis, sunstroke, gastric ulcers, skin diseases, muscle pains, etc. Many oil-soluble drugs get absorbed well in the presence of fatty food etc.
Lack of sufficient diet along with administration of drugs leads to many problems like drug accumulation, development of resistance to the drug by microbes, etc. This is because the food is an enzyme inducer, i.e., it helps generate sufficient enzymes in the liver to metabolize the toxic drugs. Thus on metabolism drugs become more water soluble and get excreted from urine.
6. To overcome stress
Many people under stress neglect food. But interestingly the same food can relieve stress. So if you find someone having stress, ask him to consume food sufficiently and you will see that he feels a bit relieved from stress.

This is a scientific basis for role of food in environment. Plants produce food in the form of fruits, cereals, nuts etc. This serves two purposes like
a) It provides food to the whole of food chain
b) For propagation of plants and other living beings.
Every fruits or nuts formed by plants have seeds in them. Supposing you eat a mango, then you will discard the seed at a distant place from the mother tree. When the seed reaches soil, it grows into a new mango plant away from the mother. Thus food helps in propagating the plants all over the earth.
Similarly, the animals in food chain also grow in a systematic fashion like when plants form flowers, the insects give rise to larva. Because, the insects can feed their larva with nectar. At the same time, the birds hatch their eggs to give birth to their young ones. They do so just at the same time because, they can feed their young ones with sufficient insect larva. So, the food helps in propagation of life and also its sustenance.
