Food as we know is essential for the growth and maintenance of the human body. However, have you ever considered the question of why does an individual eat food?

The answer to this question is that food performs three different functions.

They are:

BulletPhysiological Function

BulletPsychological Function

BulletSocial Function

Physiological function

All food goes through a complex process of digestion, absorption, assimilation and excretion. Food provides us with calories, which are metabolized in the body to provide energy. Energy is required for all the functions of the body including heart beat, homeostasis, functioning of the brain and other vital organs the body. This is the physiological function of food.

Psychological Function

Food always gives us a feel of satiety or "satisfaction." A normal well-balanced individual human eats food for both physiological and psychological satisfaction. However, sometimes individuals’ mis use food as they consider it a factor influencing their self-esteem and become victims of diet/food related conditions like anorexia or bulimia. Some individuals also go on "bingeing sprees" and lose control over their eating habits.

Social Function

From time immemorial food has been used to bring together people for celebrations as well as sad occasions. Food binds people together and no wedding/funeral is complete without the presence of food. It promotes a feeling of sharing and thus has a social function.

Being healthy and eating well is an amalgamation of all these essential functions of food.

You must have carbohydrate, protein, fat, vitamins, minerals salts and fibre in the correct proportions. If there is not enough protein, you will not be able to grow properly and you will not be able to repair yourself i.e. wounds will not heal properly. If you do not have enough energy containing foods you will feel very tired, you will not have enough energy. If you have too much energy containing foods you will become overweight. If you think that you are overweight you might try taking more exercise to "burn off" some of the excess food which you ate at you last meal.
