Fat, for people who lose weight, can be described as a deep hatred. In fact, in addition to making people fat, fat can also provide a source of energy for the body.
Recently, researchers at the University of East Anglia in the United Kingdom published a research paper entitled "Free fatty-acid transport via CD36 drives β-oxidation-mediated hematopoietic stem cell response to infection" in the journal Nature Communications.
The study shows that when the body is infected, hematopoietic stem cells can use the high energy provided by fat, thereby expanding and differentiating to produce a large number of immune cells to suppress infection.
In fact, there is some fat in the body is still necessary, not the thinner the better, just like the newborn baby, if the lack of fat, can not provide calories, resulting in hypothermia, which leads to the existing fat in the body due to the temperature drop and hardened, which will crisis life. There are some female athletes, especially sprinters, who have high muscle content and low body fat content, resulting in unstable menstruation and even amenorrhea. There is some fat in the abdomen that not only keeps warm, but also cushions my external forces, protects the organs, and also reduces friction between the intestines and reduces resistance.
For the elderly, being too thin can bring about a variety of diseases:
1. Anemia: excessive wasting people generally have the problem of unbalanced nutritional intake, insufficient intake of iron, folic acid, vitamin B12 and other hematopoietic substances;
2. Duodenal stasis: people who are too emaciated, their mesenteric and posterior peritoneal fat is scarce, and the internal organs are sagging, resulting in compression of the duodenum. Indigestion of food, showing abdominal fullness and discomfort, accompanied by pain or vomiting after meals;
3. Gallstones: People who are too emaciated generally have insufficient caloric intake, and the fat in the body tissues will accelerate the consumption, and the cholesterol will also move, resulting in an increase in its content in the bile, so that stones are formed for a long time;
4. Gastric sagging: the human body is excessively emaciated, the abdominal wall of the body is relaxed, the abdominal muscles are weak, and it often causes gastric sagging;
5. Memory decline: The fat intake and storage of the emaciated human body are insufficient, and the body is nutritionally poor, which seriously damages brain cells and directly affects memory.
