Importance of food in life
1. For energy: Food is very vital for energy. Body functions due to energy supplied from food. Food acts as fuel to generate energy in the mitochondria. Glucose from food interacts with oxygen we breath to form energy, Carbon dioxide and water molecules.
2. For body shape and form: Food gives shape and form to the body. Food contains proteins which provide aminoacids on digestion. These amino acids in the body act to build body cells and other tissues to maintain shape and function.
3. For body building. To those who go for gym and other strenuous exercise for body building, need protein. So gym instructors advice those practicing to consume high diet containing foods. For this protein rich foods like pulses, milk, egg and meat are recommended to help build enough muscles.

5. For drugs to act: Drugs act well when taken with sufficient food. Food gives strength to the body to accommodate a drug safely and also metabolise 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 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 drug by microbes etc. This is because food is an enzyme inducer i.e. it helps generate sufficient enzymes in liver to metabolise the toxic drugs. Thus on metabolism drugs become more water soluble and get excreted from urine.
6. To over come 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.
