Which substance work as
fuel in our body?
Our
body is a wonderful machine that works continuously without any break. Even
when we are in sleep, many processes such as respiration, digestion, heart
beating, etc. go on incessantly. These processes also consume fuel
continuously. Eating a balanced and nutritious diet provides the body wit all
its energy requirements.
Just
as an engine needs, fuels like coal, petrol diesel, etc. to run similarly our
body also requires fuel which provides us the energy to work with. The substances,
which act as fuel or energy for our body, are fats and carbohydrates. The food
we consume is burnt with the help of oxygen that we obtain fro breasting and
produces these constituents. The energy, which is released in the process, is
used to perform all our voluntary protein is required for growth and tissue
repair while vitamins and the minerals are necessary for the proper functioning
of various body organs.
Nutritious Food
Just as a machine needs pepper fuel, our body requires
nutrients to keep it in proper working condition. The nutrients come from the
food we consume. Our body absorbs and utilizes the useful elements form the
food we eat, and rejects those that are not needed in the form of waster
material. We excrete about 2 kilograms of urine and stools daily. We inhale
oxygen when we breathe and carbon dioxide is produced as a waste material. About
400 gram of water is excreted through the process of sweating.
Human body temperature remains constant between 980 F
and 990 F. There is a
wonderful equilibrium between the production and consumption of heat in the
body so that the body temperature remains constant. Food is measured in units
of energy, called calories.
