Of great value is the kind of fat that cells use for their construction. A particularly large amount of fat consumes our brain and nerves for our normal work. Also fats are needed for the daily synthesis of hormones in the adrenal cortex of the gonads. Fats are also needed for reproduction of healthy intestinal microflora. A small fat supply to the human body is only beneficial. So, the fat that binds the kidneys fixes them in the correct position. A dense subcutaneous layer of the fat is able to protect muscles and nerves, and also with it the normal temperature of the body is maintained.
During the process of digestion, all fats are split into two parts: fatty acids iglitserin. In the absence of essential fats, fatty acids are formed even from sugars. But three specific fatty acids human body can not be synthesized. These are acids such as linolenic, linolenic and arachidonic acids - they are called irreplaceable and very necessary. They are needed to produce some hormones, to maintain a healthy intestinal microflora and to completely restore the structures of damaged cells.
What contains useful fats ?
The main source of essential fatty acids are various vegetable oils. In the corn, sunflower, soybean and cotton oils, the content of 35% to 65% of linoleic acid is fixed. But in margarine and animal fats (butter, cream, meat fat, egg yolks) are irreplaceable and useful fatty acids. In conventional salmon, there are also few of them - only from 5% to 10%. In vegetable oils such as avocado oil, as well as almond and olive oil contains very little malinolic acid. In coconut and palm oil, and it does not.
If you eat a lot of sugar, then its excess in the body will turn into fat, which is built of fatty acids, not capable of forming compounds. Here it is our enemy - the most dense of fats, which we are so afraid of and which is very easily and quickly accumulated. It is impossible to obtain such essential fatty acids from such fat. Sugar is easily converted into fat, but fat can not already turn back into the same sugar.
Linoleic acid often helps in the prevention and even in the treatment of eczema, if it has arisen because of a lack of vitamins in the B group. The principle of its action in this case is simple: linoleic acid promotes the growth of beneficial bacteria in the intestine that produce this vitamin.
Lack of fat is the reason for completeness
This may be strange, but the lack of fat in the daily diet is valid for weight gain. First, excess weight can appear due to the delay in the liquid in the body (useful fats do not allow the liquid to stagnate). In this case, a balanced diet with the use of vegetable fats will help to quickly throw off extra pounds.
Secondly, in the absence of essential fatty acids, the sugar that enters the body is much more rapidly converted into dense, non-excreted fats. Reducing the level of sugar in the composition generates a "wild" appetite with the inevitable overeating and weight gain.
Thirdly, since it is fats that satisfy hunger best, the rejection of dishes containing them leads to the consumption of very high-calorie carbohydrate products. Extra calories are becoming overweight.
Also, fats are necessary for stimulating the production of bile and an enzyme that breaks down the zhirlipase. If there is not enough fat in the body, then little bile is released. It is stored in the cavity of the gallbladder, which contributes to the subsequent formation of the stones. If the diet for a long time is not enough fats, the gallbladder is greatly weakened, and its work is significantly (sometimes irreversibly) disrupted.
Interaction of fats and vitamins
In the absence of the necessary amount of fats and bile in the body, the development of the necessary fat-soluble vitamins can be severely impaired. They are vitamins A, D, E, and K - they are not digested without fats, they develop deficiency. Unprotected (unrefined) vegetable oil is vitamin E. In some animal fats - in cream, butter, egg yolks - contains vitamin A, we pour fat - a complex of vitamins A and D. In animal fats, also contains cholesterol-related cheeses. From it is formed in the body of vitamin D.
Natural fats from egg yolks, brains and liver are sources of useful lecithin, another "relative" of fats. In turn, lecithin is the source of the immediately bivitamins of group B (choline and inositol). Lecithin is not refined in refined oils. Vitamin E, which is part of unrefined vegetable oil, protects it from rancidity, being a powerful antioxidant. Vitamin E also protects vitamins A, D and K from oxygen oxidation. At the same time, it quickly breaks down. In frozen and refined oils, vitamin E is not contained (in spite of advertising).
To save your health for many years, you should avoid the use of hydrogenated fats. These are products such as margarine, processed cheeses, peanut paste, solid edible fats. It is also necessary to limit the consumption of saturated animal fats, especially beef and lamb fat. It is necessary to avoid foods that contain coconut oil and palm oil. Every day you need to use at least one teaspoon of pure unrefined vegetable oil. And your body will work fine, like an expensive Swiss watch.
