Fats and oils both are very important in our daily life. Our daily dietary plan needs a proportion of both of them. This article will help you understand the difference between the two.
Many of the metabolic activities and biochemical activities in the living body use fats. Lipases are the special enzymes which breakdown the fats into small particles. These breaking down of fats releases energy. Adipose tissues are present inside the outer layer of skin and they are made up of almost 80% fats. These tissues store energy in themselves in the form of lipids. These lipids are then broken down into small particles to release energy when needed. It helps to reserve energy in the body. The fats are mainly divided into two types depending upon the saturation. The saturated fats and the unsaturated fats. Every product is the combination of saturated and unsaturated fats. The foods are named as highly saturated or unsaturated according to the amount of any kind of these fats.
Oils are actually the blends of saturated, mono unsaturated and poly unsaturated oils and fats. There are many oils but some of them are considered healthier than others depending upon their saturation. Basically two types of oils are considered good. The monounsaturated oils and polyunsaturated oils are considered good oils because these oils search artery clogging cholesterol from the blood stream and takes them to the liver. So the high level of unsaturation makes a healthier oil. It means that the oils having carbon-carbon double bonds are much appreciated. The monounsaturated oils are olive oil, peanut oil and canola oil. Among these oils, peanut oil is very much appreciated because of its high thermal stability making it good for frying and other such purposes. The polyunsaturated oils are sunflower oil, oil extracted from cold water fishes such as Tuna fish. These polyunsaturated oils are very good source of omega-3 fats which helps reducing the inflammation. The polyunsaturated oils are more applicable for low temperature uses such as in salads and sauces.
In order to stay healthy, one needs good amount of oil as well as fat in their diet. A fat can be turned into liquid form by giving it some heat and rising the temperature. When the fat converts to the liquid form, it becomes oil. On further heating, the oil starts smoking. At this point it releases toxins. These toxins remain there even after the oil has been cooled down. So the deep fried food is more bad for you then a slice of butter. Less than 30% of the calories in human body should be gained through consuming fats and oils but if someone is trying to lose some weight, it should be less then 10%.
There are a number of differences among them. Fats are extracted through animals while the oils are extracted from plants.
We use both of them as alternatives because of the fact that they have 9 calories per gram.
Vegetable oils and fats differ physically by their state at room temperature. The oils are completely liquid while the fats are solid.
Regardless of their physical state, the nutritional composition of vegetable fats vs. vegetable oils is distinguished by their content in fatty acids and in particular in saturated fatty acids. Vegetable fats contain a high content of saturated fats, the so-called “bad fats”.
