Food:
Food is what is taken to supply the necessary
nutritive elements.
Diet:
Diet is a prescribed course of eating and drinking
in which the amount of food as well as the times at
which it has to be taken are regulated by the
physician for therapeutic uses.
Nutrient:
It is a constituent of food or a diet that must be
supplied in suitable amounts.

Nutrition:
It is the science of foods, the nutrients and other
substances therein; their action,interaction and
balance in relationship to health and disease.,the
process by which the organism ingests, digests,
absorbs, transports and utilizes.
Malnutrition:
Impairment of health resulting from a deficiency
excess or imbalance of nutrients.

NUTRITIONAL VALUE
Energy requirement:
The level of energy intake in relation to expenditure
which is most likely to prolong active life.
Energy for basal metabolism
Energy for physical activity
Energy expended during digestion and absorption of
nutrients
Basal Metabolism:
Minimum amount of energy needed to regulate and
maintain the involuntary essential processes.
BMR:
Number of kilocalories expended by the organism per hourwww.indiandentalacademy.com

SDA:
Specific dynamic action is the expenditure
of calories during the digestion and absorption
of food.
Calories:
Quantity of energy required to raise the
temperature of 1kg of water by 1 C

essential food groups and allows the body to
function at an optimal level free from disease and
malaise.
