Lecithin, whose biological name is phosphatidylcholine, is the highest content of phospholipid in human tissues, an important component of nerve tissues, and belongs to advanced neurotrophins. Lecithin accounts for about 1% of the body weight, but it accounts for 30% of the brain weight in the brain. In brain cells, it accounts for 70 ~ 80% of its dry weight. Lecithin is concentrated in the brain and nervous system, blood circulation system, immune system and important organs such as heart, liver, lung and kidney.

The main functions of lecithin are as follows:

1, lecithin is the "scavenger" of blood vessels. Lecithin has the function of emulsifying and decomposing oil, which can emulsify cholesterol and neutral fat attached to the blood vessel wall into microparticles, dissolve them in the blood and transport them to the liver for metabolism and excretion. Lecithin can also reduce blood surface tension, blood viscosity and circulation resistance, thus ensuring that blood with rich nutrition and sufficient oxygen flows to the brain unimpeded.

2. Lecithin is the protector of the liver. Choline in lecithin plays an important role in fat metabolism. If the choline in the body is insufficient, it will cause fat to accumulate in the liver, form fatty liver, even inflammation and swelling, hinder blood circulation, and cause hepatocyte necrosis. Cholesterol excess is the main cause of liver cirrhosis. Lecithin supplementation contributes to liver cell regeneration, promotes fat degradation and excretion, and reduces fat deposition in liver cells, thus effectively preventing fatty liver and liver cirrhosis. In addition, lecithin can also enhance the detoxification function of human body and eliminate the harm of tobacco, alcohol and benzene to human body.

3. Lecithin is a nutrient suitable for diabetic patients. It can relieve some symptoms of diabetes, especially for diabetic patients with arteriosclerosis. Its main mechanism may be to repair the damaged cell membrane and intima system, enhance the function of pancreatic cells, thus increasing the level of insulin, and then reducing the level of blood sugar.

4. Lecithin is a good psychological mediator. With the increasingly fierce social competition, people have been in a tense environment and under various pressures for a long time, often suffering from anxiety, impatience, irritability, insomnia, tinnitus and other symptoms, that is, autonomic nervous disorder. Taking lecithin regularly can make the brain nerves get nutritional supplements in time, keep the brain in a healthy working state, help eliminate fatigue, intensify brain cells, and improve impatience, irritability, insomnia and other symptoms caused by mental stress.

5. Lecithin is a health care product in beauty beauty. Lecithin is an indispensable substance in every cell of the human body. If lecithin is lacking, it will reduce the regenerative ability of skin cells, resulting in rough skin and wrinkles. If lecithin can be properly ingested, the skin regeneration vitality can be guaranteed. Coupled with the good hydrophilicity and lipophilicity of lecithin, the skin will of course be shiny. In addition, inositol contained in lecithin is the main nutrient of hair, which can inhibit hair loss and reduce white hair.

Traditional Chinese medicine in China is known as "supplementing the brain with the brain", and it is believed that "the same kind of people can seek each other and return to their own homes". Eggs, seafood, soybeans and their products, walnuts, sesame seeds, sunflower seeds, animal liver and brain marrow all contain a lot of lecithin. Nothing is more economical than fish head soup, which nutritionists call "brain-nourishing soup".

Although lecithin has a peculiar effect of strengthening the brain and strengthening the body, you can't expect it to complete a comprehensive nourishing task. Only a balanced intake of various foods can be beneficial to the health of the whole body.

Suitable for people:

1, the US Food and Drug Administration (FDA) stipulates that phospholipids must be added to infant milk powder.

2. Students, intellectuals and middle-aged and elderly people: Lecithin can enhance brain vitality, eliminate brain fatigue, enhance memory and improve study and work efficiency. But also can repair damaged brain cells and prevent the occurrence of Alzheimer's disease.

3. Patients with long-term drinking, overnutrition and fatty liver: Take10-15g lecithin every day. After 3-5 months, the blood lipid index can return to normal level.

4, diabetic patients: eating more than 20 grams of soybean lecithin every day, the recovery speed of diabetic patients is quite obvious, many patients do not need to inject insulin. It is more effective for patients with complications such as diabetic gangrene and arteriosclerosis.

5. Patients with gallstones: Taking soybean lecithin every day can not only prevent the formation of gallstones, but also decompose and eliminate the formed gallstones to varying degrees.

6. Lady who loves beauty: Lecithin is a natural antidote that can decompose toxins in the body. By increasing heme, it can provide sufficient nutrients such as water and oxygen for the skin, and make the skin smooth and moist.

matters need attention

edit

Many consumers will find it difficult to choose many brands of lecithin health care products on the market. How to buy high-quality products is also a matter of great concern to everyone.

First of all, it depends on whether the outer packaging of the product is formal. Whether the content of lecithin in the unit product is clearly put forward and the content is also the main factor to determine the price and quality. The description part of the label of imported health care products must be explained in Chinese, and it must comply with the regulations of the Ministry of Health, especially the content of functional components, health care function, suitable population, taking method and dosage of the products must be explained in detail. At the same time, we should also pay attention to the expiration date of the product, especially in summer, because lecithin is not heat-resistant, exceeds the expiration date or the product is poorly sealed, the content of its effective components will be greatly reduced, and the expected health care effect cannot be achieved.

Secondly, we should choose a brand with good after-sales service. Because the food with high lecithin content is not ordinary food, although there are no side effects, the reaction after taking it varies from person to person. If professional health consultation is not provided, it is likely to cause consumers to get twice the result with half the effort due to the use reasons during the taking process.

Third, look at the product itself. The best lecithin product is extracted from eggs, so if the raw material of lecithin food comes from eggs, the quality is naturally superior, but the price will be higher; At present, many lecithin capsules sold in the market are mostly from soybeans or leftovers of soybeans, so the quality is uneven. High-quality soybean lecithin capsule health care products should be brown, clear, transparent, without any precipitation or impurities, and the capsules are smooth. If there is slight adhesion between particles, they can be separated by slight shaking, which is a normal phenomenon. If the liquid seeps out of the bottle after opening the package, or the capsule particles stick together and cannot be separated completely or there is wire drawing, then this lecithin product belongs to inferior products.
