Food, glorious food. For
some it’s a sensory
pleasure, for others just
a fact of life, but for
all of us eating has an
important impact on our
health and wellbeing. A
good diet is low in fat,
cholesterol, sodium and
sugars; and high in vegetables,
fruits, beans, nuts and
whole grains. Eating well
can make a real difference
in your health and longevity.
Our diet should provide
adequate amount of all nutrients
to maintain good health
and physical efficiency.
Daily food intake should
be such that of the total
consumption, about 15 to
20% is protein, 40 to 50%
is complex Carbohydrates
and 20 to 30% is fat.

| Food |
| Food
is any substance, usually
composed primarily of carbohydrates,
fats, water and/or proteins,
that can be eaten or drunk
by an animal for nutrition
or pleasure. Almost all
foods are of plant or animal
origin, although there are
some exceptions. |

| Nutrition |
| Nutrition
is a science that examines
the relationship between
diet and health. Nutrition
is the provision, to cells
and organisms, of the materials
necessary (in the form of
food) to support life. Many
common health problems can
be prevented or alleviated
with good nutrition. |

| What
is Nutrients? |
| Nutrients
are substances derived from
food during the process
of digestion. There are
three main groups of nutrients
contained in food which
are needed by the body in
differing amounts. They
are carbohydrates, proteins,
and fat. These major nutrients
are needed by the body for
growth, repair, maintenance
and energy. In addition,
the body requires fibre,
vitamins and minerals which
are present in varying quantities
in different types of food.
Good nutrition requires
a balance of the right nutrients,
that is, getting the proper
amount, or proportion, of
each one. |

| Balanced
Diet |
A
balanced diet is a diet,
which provides sufficient
amounts of carbohydrates,
fats, proteins, vitamins
and minerals nutrients to
maintain good health and
with a small provision for
periods of leanness or scarcity.
The human body requires
food to provide energy for
all life process and for
growth.Eating a well balanced
diet on a regular basis
and staying at your ideal
weight are critical factors
in maintaining your emotional
and physical well-being.
Being over weight/under
weight can lead to certain
chronic conditions such
as diabetes, high blood
pressure and heart disease.

| Fluid |
| Other than balanced diet, we require adequte amount of fluid or water which helps in proper digestion of food.
Fluid intake in the form of water based drinks is also essential for good health. Water is essential for the correct functioning of the kidneys and bowels. At least 6-8 glasses of plain water should be drunk each day, more in hot weather. |
