If one cant reduce the use of fat,reduce fat by using less saturated oils,which has less fatty content,that causes damages to your health.
Saturated fats are found not only in animal products and dairy
products but also in some plant products.The less saturated fat you
eat ,the better.Our bodies don’t need it and it is the fat which
contributes to raised levels of blood cholesterol ,which in turn
increase the risk of heart diseases.

Polyunsaturated fats are primarly found in vegetable oils such as
safflower,sunflower,soybean,sesame seed and cotton seed.Some studies
indicate that polyunsaturated fats can lower blood cholestrol,reducing
the risk of heart diseases.But repeated reheating of polyunsaturated
oil at high temperature until it darkens in colour turns it into
saturated fat that is better avoided .For this reason avoid deep
frying food containing polyunsaturated fat.A special type of
polyunsaturated fatty acids-the Omega-3 found in fatty fish such as
salmon,sardine and mackerel has been found to be effective in reducing
high blood pressure heart disease risk.This explains why Eskimos whose
diet depend largely on fish rarely die of heart failure.
Monounsaturated fats are found in oils such as olive ,peanut
oil,peanut butter rapeseed and foods such as
almonds,cashews,avocados.Latest research confirms that replacing
saturated fats with mono unsaturated fats may decrease the level of
blood cholestrol.Most mass-produced margarine ,salad oil,mayonnaise
and snack foods are hydrogenated for a longer shelf life.
