A healthy diet is one that helps maintain or improve
general health. A healthy diet provides the body with
essential nutrition: essential fatty acids, vitamins,
minerals, and calories. Where lack of calories is not an
issue, a properly balanced diet (in addition to exercise)
is also thought to be important for lowering health
risks, such as obesity, heart disease, diabetes,
hypertension and cancer.
What is a healthy balanced diet?
When it comes to healthy
eating the most important
thing to remember is that
there are no such things as
‘good’ and ‘bad’ foods. The
occasional biscuit or packet of
crisps isn’t going to do any
harm as long as the rest of
your diet is a healthy balance.
The secret to a healthy diet is
balance.
Why is a balanced diet important?A balanced diet is one that provides the body with all the
essential nutrients, vitamins and minerals required to maintain
cells, tissues and organs as well as to function correctly. A diet
that is lacking in nutrients can lead to many different health
problems ranging from tiredness and lack of energy to serious
problems with the function of vital organs and lack of growth and
development.

maintain good health. Each vitamin does a different
job in the body and so a lack of any one vitamin
can seriously affect our health. Vitamins are

amounts. Different mineral salts are needed
for different purpose. Liver, kidney, red

energy. But the more important role
of proteins is to help our body grow.
They are used to make new cells and
to repair damaged ones. What
happens when we don't get enough proteins in our diet?
We will not grow properly and our
muscles will become weak.
Proteins
Fats can be used by the body to
produce energy in addition fats can be stored in the body for a
long time. Some of this body fat
helps to keep us warm. Some of it
is used by the body to release
energy whenever we don't eat
enough food. It can lead to heart
disease.

percent of our body weight.
