Balanced diet and
calorific value

Prepared by: Pn. Nurulkamilah binti Khairir

Student is able to: 2.1 Balanced diet
and calorific value
 Describe balanced diet

 Conduct an experiment
to estimate the energy
value in food samples

 Justify the effects of
consuming calories
that do not meet
individual requirements



A balanced diet is a diet that includes all the
classes of food in the right quantity according

to the individual’s body requirement.

Is a serving of nasi lemak an example of
balanced diet?

Calorific Value of Food

Calorific value (energy value) of food is the
amount of energy that is released from the
complete oxidation or combustion of 1 g of

that food

S.I unit for calorific value: J kg -1

Energy is normally measured in calorie (cal),
kilocalorie (kcal), joule (J) or kilojoule (kJ)

1 cal = 4.2 J
