OPTIMUM NUTRIENTS
❑Optimum nutrition means that a person
is receiving and utilizing essential
nutrients in proper proportions as
required by the body while also
providing a 'reserve'.
NUTRITIONAL STATUS
❑Nutritional status is the condition of
the body as it relates to consumption
and utilization of food.
❑The nutritional status of a person may
be either good or poor.
❑Good nutritional status refers to the
intake of a well-balanced diet, which
supplies all the essential nutrients to
meet the body's requirements. Such a
person may be said to be receiving
optimum nutrition.

POOR NUTRITIONAL STATUS
❑Poor nutritional status, also known as
malnutrition, is a serious condition that
occurs when a person's diet doesn't provide
the right amount of nutrients to maintain
their body's functions and tissues.
❑Poor nutritional status refers to an
inadequate or even excessive intake or

❑Malnutrition refers to the
physical effects on the human

BASAL METABOLIC RATE (BMR)
❑Basal Metabolic Rate (BMR) is the
amount of energy your body uses to
maintain homeostasis while at rest.
❑It's also known as resting metabolic rate
(RMR).
❑BMR is a measure of how many calories
your body burns while performing basic
life-sustaining functions, such as
breathing, maintaining body
temperature, and circulating blood.
❑It accounts for about 60–75% of your
daily energy expenditure.

❑He studied the role of respiration
in metabolism of food.
❑He is known as "the father of
nutrition science" and modern
