High energy dense diets have been linked
with obesity.
Such diets tend to be low in plant food and
high in "indulgences" i.e foods containing lots
of sugar and/or fats. A low fat diet can still be energy
dense if it does not contain enough vegetables, fruits and
low sugar cereals. A high fat diet can have a low energy
density if it contains lots of plant foods. High
energy dense foods promote high energy intakes.
Energy
density = the number of kilojoules (kJ) per gram of food.
- A
high energy dense food
has many kJ per gram of food

e.g chocolate has 22 kJ/gram,
nuts has 30kJ/gram
sweet biscuits 20kJ/gram
tasty cheese 14kJ/gram.
- A
moderate energy dense food
has moderate kJ per gram of food
e.g bread has 10kJ/gram,
rice has 5kJ/gram,
flavoured low fat yoghurt 4kJ/gram.
- A
low energy dense food
has few kJ per gram of food

e.g apple, celery, low fat natural yoghurt have <2
kJ/gram
