Fat usually means fatty acids available in living beings or food. Fat is main energy sources &
stores energy for our body needs. Fat plays vital role in metabolic functions of human
body. Fat plays vital role in maintaining healthy skin & hair, insulating body organs against
shock, maintaining body temperature and promoting healthy cell function.
Fats available in common foods like milk, butter, tallow, lard, bacon, and cooking oils etc.
The human body also produces fat that it needs from other food ingredients, except for a
few essential fatty acids that must be included in the diet.
Fats in food available in several forms like saturated fat, unsaturated fat, monounsaturated,
Different foods contain different amounts of fat with different proportions of saturated and
unsaturated fatty acids.
We can say there are two kinds of fats as bad fats and good fats. As the fats and oils in most
natural and processed foods contain both unsaturated and saturated fatty acids and
avoiding of saturated fat is unrealistic and possibly unwise in our daily life.

lifestyle we intake more saturated fatty acid we intake excess amount of rich fats from
one’s daily calorie intake , which is the main threat of having cardiovascular diseases,
diabetes or death , high risk of obesity and heart disease.
Replacing bad fats with good fats reduces risk of cardiovascular diseases, diabetes or death,
high risk of obesity and heart disease. These studies prompted many medical organization
and public health department including WHO (World Health Organization) to officially issue
the advice for healthiness of human beings.
As per recommendation of United States Food and Drug Administration (FDA) saturated
fats should not exceed 30% of one’s daily calorie intake also it does not advice complete
elimination of saturated fat.
A 2003 report by the World Health Organization (WHO) and the Food and Agriculture
Organization (FAO) recommends to limit the saturated fatty acids to less than 10% of daily
energy intake and less than 7% for high-risk groups. A general 7% limit was recommended
also by the American Heart Association (ASA) in 2006.
