What Does Fat Really Represent
Some people do not eat food that containing fat and cholesterol since they are the main enemies of a slim figure. Others people eat fried pork with a layer of fat with pleasure and enjoy their life. Let us examine fat as a substance that plays an enormous role in our life activity.
Fats are a source of energy just as carbohydrates are. Only fats contain two times more energy as carbohydrates do, in one gram.
Fats can be in solid or liquid state, from vegetable or animal origin. Fats can be categorized into saturated fats and unsaturated fats. They all consist of glycerin and fatty acids. The composition of fatty acids and their amount in one gram of fat, amount to the benefit of our body.
What kinds of Fats are there?
Saturated fats are digested poorly by our body. These fats are of animal origin, coconut oil, palm oil.
Unsaturated fats are digested well by the body. A part of them is transformed into other acids, which are vitally important for us. These fats are of vegetable origin. There are trans fats or partially hydrogenated fats. These are artificially created fats that were created by the change of their structure. They are suitable for long-term storage and multiple uses. However, for the human body, they are very harmful.
Fats perform several important functions in our body.
Fats are actively involved in the metabolism.
There is a concept: the essential and nonessential fatty acids. Nonessential fatty acids are produced by the body itself. Essential fatty acids are not produced by our body. That is why our body needs to get essential fatty acids with fats from food. They are unsaturated fatty acids - linoleic, linolenic, and arachidonic. These fats take part in chemical reactions that allow us to live, reproduce, and grow. They support the integrity of the body and are a constant source of energy. Another important function of fats is their ability to dissolve vitamins. Vitamins: A, E, D, K can be dissolved and be digested by the body only in fats.
Thermoregulatory function of fats.
Our organism needs supplies of energy substances in the form of fat. It is hypodermic fat. Hypodermic fat stores as energy supplies by our body. A layer of fat is stored under the skin for the protection from hypothermia. If your nutrition pattern is right, this layer of fat usually consists from a couple of millimeters up to 2 centimeters.
Cleansing action of fatty acids
Cells of our body in the process of life gradually become clogged with different molecular fragments. These defective molecules or atoms destroy the cell, trying to enter into random chemical bonds. This entails are mutation in the cells and one of the causes of cancer. Essential fatty acids are broken down into individual components. These components affect the tone of smooth muscles of internal organs, body temperature, and improve the immune system. Regulate the cholesterol level in blood. Other components of unsaturated fatty acids affect blood viscosity.
Essential fatty acids improve the condition of vessels during atherosclerosis, and thrombosis. They have a beneficial effect on bone and muscle tissue.
What is cholesterol?
When fats are mentioned, immediately their connection with cholesterol is noted. The cholesterol is mentioned almost on food lables. The excess of cholesterol is delayed in the vessels in the form of plaques. Vessels become inelastic. Their lumen is narrowed. The result can be a disease of the cardiovascular system. Cholesterol is a substance of organic origin. Most of cholesterol is produced by the body. Only 20% of cholesterol is received from the food. It is very vital for all cells of our body. Cholesterol strengthens the cell membrane. This means that the boundary between the cell and the surrounding medium strengthens. Cholesterol helps the body produce vitamin D, it is involved in the production of hormones, bile acids, and affects the speed of the signals in the brain. Some researches claim the protection from cancer.
However, this life-giving substance can become an implacable enemy of your body. Unhealthy cholesterol is free cholesterol. Our body regulates the production of essential substances. In case of excessive consumption of fat, especially of animal origin, there is an excess of cholesterol. It is completely absorbed by the body. In this case, the body produces less cholesterol. During excessive consumption of fats and carbohydrates the balance is gradually disrupted. Increased cholesterol levels shows that there are failures in the regulatory capability of the organism. The reason may be more damage at the cellular level. Therefore, the body tries to eliminate them.
We try to meet the needs of our taste, increased appetite and different preferences in food. We should always remember the priority is to satisfy the immediate needs of our body in order to stay healthy and live a full life.
