2. The choice of fat. In the fat part, medium-chain fatty acids (MCT) with better absorption and utilization rate can be appropriately used to increase the intake of concentrated calories. Pure medium-chain fatty acids (MCT) need to be used together with general oils and fats because they do not contain "essential fatty acids". It is suggested to use medium-chain fatty acid products to mix essential fatty acids (such as sanduo high energy) to avoid the lack of essential fatty acids. It is generally recommended that medium-chain fatty acids account for 60% of the total oil consumption.
Extended data:
Fat is a triacylglyceride composed of glycerol and fatty acids, in which the molecule of glycerol is relatively simple, but the types and lengths of fatty acids are different. Therefore, the nature and characteristics of fat mainly depend on fatty acids, and the types and contents of fatty acids contained in fat in different foods are different. There are more than 40 kinds of fatty acids in nature, so various fatty acid triglycerides can be formed; Fatty acids usually consist of 4 to 24 carbon atoms.
Function:
1, keep warm: unlike animals, the human body has thick fur to protect the body, reduce heat loss and avoid frostbite in winter. Therefore, the fat on the body surface plays a role similar to animal fur, which can regulate body temperature, avoid excessive heat loss, and play a role in cooling down when the body temperature is too high.
2, protect the internal organs: there is also fat around the internal organs of the human body, on the one hand, it plays a buffering role to prevent excessive vibration during exercise.
3. Store calories: When the human body consumes more calories than it needs for activities, the calories will be stored in the form of fat. When the human body exercises or lacks heat, fat will burn to generate heat to maintain human activity and basic metabolism.
4. Promote skin health: Human skin and hair need fat to stay healthy. When fat is insufficient and sebum secretion is reduced, it is easy to have rough skin, itching, increased dandruff and dry hair.
5. Raw materials for hormone production: The production of estrogen is inseparable from the participation of fat. When there is less fat in the body, the secretion of estrogen is affected, which leads to irregular menstruation, amenorrhea and accelerated aging.
6, protect the bones: too little body fat, the human body is too thin, when the human body is mechanically injured, it is prone to fractures, bone damage and other phenomena.
7. Promote the absorption of fat-soluble vitamins: vitamins are also divided into fat-soluble vitamins and water-soluble vitamins. Fat-soluble vitamins often exist in fat and are more easily absorbed in the presence of oil.
