Consuming
too much fats and oil of any kind is harmful but excluding
them from the diet deprives the body of important nutrients.

in our body, and they are the basis
for every hormone, brain, and nervous system functions.
One gram of fat gives 9 calories and
1 gram of protein and carbohydrates gives only 4 calories.
Research show that if you eat 100 calories of carbohydrates
you have to burn about 23 calories just to process
it where as in the case if you eat 100 calories of
fat, it takes the body only 3 calories to process
it.

| Fat is
essential for the healthy development of our
body and an adult needs approximately 25
g a day. It is rich source for energy and helps
to provide fat - soluble
vitamins A, D, E, K and supply of fatty
acids for healthy skin and regulating the body’s
metabolism.
Fats may occur as either oils or solids form. Generally,
oils are unsaturated (fatty acids) while solid fats
are saturated. Saturated fat found
in all forms of meet, milk fat, butter, ice cream, egg
yolk, coconut oil, palm oil etc. and it tend to raise
the level of cholesterol, triglycerides
and low - density lipoproteins.

Unsaturated fats such as soybean, safflower,
ground nut, gingili, maize oil may even lower the cholesterol
level. Trans fatty acids are generated
while food processing (by the hydrogenation process)
and also exists in beef, mutton and dairy products.
Generally a saturated fat is solid at room temperature;
an unsaturated fat is liquid at room temperature.
The unsaturated fatty acids can be
subdivided in to monounsaturated and polyunsaturated.
Monounsaturated fatty
acids are available in olive oil, rapeseed oil and
also in some nuts.

Polyunsaturated fatty
acids are available in some of vegetable oils, walnuts,
almonds and fish oils and contain Omega 6
(derived from linoleic acid) and omega 3
(derived from linolenic acid) which help to reduce
inflammation and tendency of blood to clot, and helpful
in the treatment of heart diseases.
Replacing saturated and trans fatty acids with mono
unsaturated fats (olive oil) or polyunsaturated fats
(sun flower oil, Soya and Corn oil) lower cholesterol
level and rich source of vitamin E which may protect
heart disease.
A low fat diet will help to reduce the body weight.
