Phospholipid is one of the main components of biological cell membranes. It mainly exists in the cells of animals and plants and is an essential nutrient for human health. Among plants, soybean seeds have the highest content, about 1.2% to 3.2%; it is the third nutrient in soybeans besides protein and fat. Its main components are: 30% lecithin and 30% cephalin. Inositol phospholipids account for about 40%; in the human body, phospholipids are indispensable substances. The functions of soybean phospholipids and their nutritional and health care functions are as follows: Functions of soybean phospholipids 1. It has the function of regulating metabolism and enhancing physical fitness of the human body. During high-intensity physical activities and sports, muscle cells and lecithin's information transmission and material transmission functions obtain the required nutrients and energy and eliminate metabolites in the body. During this physiological cycle, lecithin will be decomposed and consumed in large quantities. , at this time, only by replenishing enough lecithin in time can the human muscles continue to obtain energy and nutrients. This is because lecithin is one of the indispensable components of cells. Lecithin can effectively enhance cell functions, improve the metabolic capacity of cells, enhance the ability of cells to eliminate peroxidized lipids, and provide the energy needed by the human body in a timely manner. This is the main reason why the human body will obviously feel energetic and less prone to fatigue after consuming lecithin. At present, the significant effect of lecithin on improving the performance of endurance sports such as marathon and swimming has been demonstrated by Western countries. Effects of soybean lecithin 2. It has the functions of eliminating brain fatigue, enhancing IQ, and improving memory. The proportion of phospholipids in the human brain is as high as about 30%. They play an important role in information transmission in human intellectual activities. Phospholipids are also the main source of choline needed by the human body, and choline reacts with acetate coenzyme A in the human body under the action of acetylase in the human body to generate acetylcholine, which activates brain cells and thereby improves the body's response Ability, memory and intelligence level. When the choline content in human blood is insufficient, beans or soy foods can be consumed to supplement phospholipids, which has a significant preventive and therapeutic effect on neurasthenia, brain fatigue, memory loss, and Alzheimer's disease. Effects of soybean lecithin 3. It has the functions of lowering human blood cholesterol, regulating blood lipids, and preventing atherosclerosis. Lecithin can dissolve the fat-soluble substances triglycerides and cholesterol lumps in the blood and on the blood vessel walls, turning them into small particles. Increase blood fluidity and permeability, reduce blood viscosity, allow it to be smoothly excreted through cell metabolism, thereby reducing fat deposition on blood vessel walls and causing atherosclerosis. Functions of soybean lecithin 4. Function of preventing and treating gallstones The so-called gallstones refer to the formation of stones in the bile ducts of the human body. The main components of bile in the gallbladder are cholic acid, cholesterol and phospholipids. Because phospholipids can dissolve cholesterol, when the phospholipid content in human bile is too low, cholesterol will precipitate in the gallbladder and gradually form stones. Therefore, phospholipids can not only prevent the formation of gallstones, but also partially dissolve already formed stones to achieve auxiliary treatment, thereby restoring the normal physiological functions of the gallbladder. Functions of soybean phospholipids 5. Function of protecting human liver and preventing and treating fatty liver. Choline in phospholipids plays an important role in human body’s fat metabolism: if there is insufficient choline in the human body, it will affect fat metabolism and cause fat to accumulate in the liver. Fatty liver gradually forms, and a large amount of fat accumulates, which can also cause liver cells to rupture, connective tissue to strengthen, and then cause liver cirrhosis. Therefore, to prevent and prevent liver disease, it is necessary to supplement phospholipids, which have a good auxiliary therapeutic effect in helping to restore liver function and prevent and treat liver cirrhosis. In addition to the functions listed above, soy lecithin also has the functions of delaying aging, anti-aging, and preventing and treating osteoporosis in the elderly. Ordinary people can regularly eat soybeans or soybean foods for daily health care. It is natural, nutritious and has no side effects. It can be said to be the best choice for health care and disease prevention.
