Journey That The Food We Eat Makes
In The Body
We obtain the energy needed for bodily functions from
various foods and drinks. However, every food that we
eat, for example pasta, the meat or the banana, needs
to be digested first in order to be ready to be used
in the body. These foods are used by body cells after
they are digested. The sugar contained in a banana or
in an apple provides fuel for your cells and increases
your energy; the proteins contained in meat are essential
for the growth of your cells, and thus of your body.

were approximately 2-3 kilograms (4,5-6,5 pounds) when
you were born. Your weight will increase to 30-35 (65-75)
when you are 10, to 40-50 kilograms (90-110 pounds)
when 15 and 50-60 kilograms (110-130 pounds) when 20-25
The reason for this huge difference is
the fact that the substances in the foods you consume
are added to your body in time. Some of these foods
provide the energy you require to ride your bicycle,
to run and to play, whereas some are added to your body
and constitute your flesh and bones. Waste matter is
discharged from the body. All these processes are performed
in your digestive system. Organs and glands including
your stomach, intestines and pancreas have roles in
The functioning of the digestive system
is similar to the working of a petroleum refinery. Crude
oil arriving at the refinery as raw material is processed
by machines and refined so as to be usable. The foods
that we eat are raw materials in the first stage and
are then processed in the stomach so as to be used by
the body. Having been broken down in the stomach and
the intestines, foods become ready to be used as the
nourishment of the cells and are conveyed to relevant
regions of the body via blood vessels.
A single parent substance is processed
in a petroleum refinery and a variety of products, for
example gasoline, which is a fuel for automobiles, or
the rubber used as the sole of your shoes, are derived
from it. Likewise, the nutriments in the foods are broken
into fats, sugars and carbohydrates in the stomach.
But remember that what happens in your stomach after
you eat a delicious sandwich is even more complex than
what happens in a refinery. Moreover, this series of
actions which we will soon discuss does not take place
in a gigantic factory, but in a very small region in
your own body.
The total length of the passage through
which food is digested is 10 meters (30 feet). This
is 6-7 times the average human height and it is marvellous
how such a length is fitted into our bodies. How is
it that such a long canal has been placed in a human
body? The answer to this question reveals once again
that there is a special design in the creation of our
Since the digestive tract, as you can
see in the picture in the picture above, is coiled up, it
is fitted into a very small area, despite its length.
This special shape is the perfect design of our Lord,
Who created everything. This feature of the digestive
system is only one of the wonders that Allah created
in our bodies.
Do you know why your teeth have
reason why they have different shapes is that each has
different tasks. For example your front teeth are sharp,
so you can bite an apple easily. What if the molar teeth
were in the front? Yes, you are right. You would not
be able to bite a piece off the apple with your molars.
Likewise, if your front incisors were at the back, you
would not be able to grind the food you eat.
As in every single part of your body,
the teeth in your mouth are also arranged by Allah in
the most convenient and advantageous order for you.
Beneficial bacteria live at the
back of your tongue
are generally known to produce diseases and, to be protected
from their harmful effects, people should be careful
about the cleanness of both their bodies and the environments
they live in. However, not long ago scientists discovered
the presence of some beneficial bacteria in the human
body, particularly at the back of the tongue. Yes, you've
read it correctly; there are beneficial bacteria in
your body. The duty of the bacteria behind your tongue
is to kill the harmful microbes in your stomach. But
surely this is not an easy task and it demands a series
of actions. First of all, bacteria convert the nitrate
found in green-leafed vegetables like lettuce into nitrite.
However, the process is not over yet. Nitrite, in combination
with the saliva secreted in the mouth, has an antimicrobial
effect. In other words, the bacteria behind your tongue
help in the production of a microbe-killing substance.
As you know, microbes cause various diseases. Thanks
to the beneficial bacteria that produce a microbe-killing
substance, you are protected against many diseases.
These beneficial bacteria are one of the manifestations
of the compassion of our Lord, Who created our bodies
in the most perfect way. Allah has given us many beauties
and gifts. That these gifts are innumerable is related
in a Qur'anic verse as follows:
If you tried to number Allah's blessings,
you could never count them. Allah is Ever-Forgiving
and Most Merciful. (Surat an-Nahl: 18)
