Duties of fat in a human body
- They are structural part of
cell. Phospolipids are an important component of a cell membrane.
- Glycolipids, lipoproteins and
steroids work as vitamins and hormones as well.
- Fats are the most economical
part of a human body after carbonhydrates.The amount of energy given by
fat is (1 gr. 9,3 K cal.) and it doubles the energy given by the
same amount of carbonhydrates and protein.
- A large amount of metabolic
water appears when fats are used in oxygen based breathing in cells. Energy
is gained when stored fat is burned in bodies of animals travelling in
long desert roads, and those which sleep in winter, during that period
these animals supply a part of their water need as metabolic water appears
from the burned fat.
- Fat beneath skin and around
organs protect the living thing from cold and hits. Layer of fat beneath
skin is really thick especially in whales, seals and other sea mammals.
- It is the source of A, D, E, K vitamins dissolving in fat and helps them to be
absorbed
- It provides growth and normal
metabolic events.
- It helps the saturation
feeling to occur
- Essential fatty acids which
cannot be synthesized in body can be taken by fats
- It is effective in protection
of flexibility of human skin.
In
conclusion:
Fats as
nutrition:
- Saturated fats are butter,
animal fats and tail fat , so they consist cholesterol.
- Margarines ( trans fat) is
acquired from vegetable liquid oil in nutrition industry. Solid margarines
are solid because they are saturated
with hydrogen in producing process and are in the saturated fatty acid group. They
consist cholesterol if animal fat and milk is added.
- People usually consuming food with over saturated fatty acids may
have cardiovascular diseases. In One of the
diseases , arteriosclerosis, lipid accumulates in side of the blood vein .
These accumulations prevent the blood to flood and decreases the
flexibility of veins. In order to protect heart health, a little amount of
saturated fat should be consumed.
- Saturated fatty acids prevent
cleaning of low volumed lipoprotein in blood. As a result, they cause
occlusion in veins as they form accumulation in veins. It is known to
increase LDL cholesterol level and tendency to diabetes.
- Consuming fried food
repeatedly rises risk of cancer as fried oil’s comical structure is
destroyed. During cooking, it is known that multi unsaturated fatty acid
is formed in fried oil.
- %25-30 of energy needed per
day should come from fat .It is impossible to live without consuming fat.
- Calorie taken with saturated
fatty acids ,although being the same with other fatty acids’ calorie, is
the reason for gaining weight.
- Although the effects of
single unsaturated fatty acids on LDL cholesterol is neutral, it has an effect on increasing high
volumed lippoorotein. Single unsaturated fatty acids are known to play a
role in healing cardiovascular diseases’ risk factors.
There are
a lot of positive and negative effects of fatty acids found in fats on
nutrition and health. Saturated fatty acids are the reason for especially
cardiovascular diseases and gaining weight with fat. Unsaturated fatty acids
usually have positive effects. But, whole nutrition diet should be taken into
considerate and enough and balanced fat should be consumed, fatty acids should
be below limits and rated to each other. As a result of eating food consisting
high amount of trans fat, rising in LDL cholesterol and decrease in HDL
cholesterol occur. This situation leads to cardiovascular diseases. Consuming
Omega 3 and Omega 6 fatty acids has positive effects. But these two acids
should be consumed proportionately. It is obvious that KLA is protective
against cancer, positive effect in immunity system and cardiovascular diseases,
and preventing weight gaining and obesity.
For a
balanced diet, it is essential for the consumers to become conscious about
fatty acids.
