Fat Loss > What are Fats and how do they effects us
There are two main types of fat saturated and unsaturated. Saturated fats are the ones we should try to avoid as the more saturates we eat the more cholesterol the body produces. This builds up in our blood and can increase the risk of developing heart disease and other health problems.
Fats help the body use some vitamins and keep the skin healthy. They also serve as energy stores for the body. In food, there are two types of fats: saturated and unsaturated
Saturated fas associate in closely-packed structures with van der Waals interactions all along the length of their side chains. The increase in interactions raises the melting point. These Fatty Acid aggregates are solids at room temp. Saturated fats are mostly found in animal products such as meats and some dairy produce. They can be found in some vegetable oils like coconut oil or palm oil, in hard margarine and cooking fats. Sometimes they can be found as "hidden fat" in cakes, biscuits, chocolate and puddings.
Unsaturated fats are essential to the body although only in small amounts. They include polyunsaturated oils and monounsaturated fats. Unsaturated fats are found in vegetable oils such as sunflower, corn, rapeseed and olive oils. They can also be found in nuts, soft margarines labelled "high in polyunsaturated oils", also oily fish such as sardines, herring, trout and pilchards contain high levels of polyunsaturated oils.
Both polyunsaturated and monounsaturated fats may help lower your blood cholesterol level when you use them in place of saturated fats in your diet. But a moderate intake of all types of fat is best. Use polyunsaturated or monounsaturated oils — and margarines and spreads made from them — in limited amounts. This is recommended in place of using fats with a high saturated fat content, such as butter, lard or hydrogenated shortenings.
