What is the function of lecithin? I believe many people have eaten this kind of food. Its benefits to the body are endless. The most important thing is to take it regularly and quantitatively. The substances contained in this food have a great influence on the body. Let's introduce the function of lecithin for your reference.
What is lecithin for? 1 What is lecithin?
Lecithin is an important nutrient found in the past 50 years.
Lecithin, whose biological name is phosphatidylcholine, is the substance with the highest phospholipid content in human tissues, is an important component of nerve tissues and belongs to advanced neurotrophins. Lecithin accounts for about 1% of human body weight, but it accounts for 30% of brain weight in brain. And accounts for 70-80% of its dry weight in brain cells. 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 important role of lecithin
1, ensure the health and normal function of brain cell membrane, ensure the nutrient input and waste output of brain cells, and protect the healthy development of brain cells. Lecithin is a very important educational nutrient for fetuses and infants in the critical period of brain development.
2. It is an important source of information transmission media between nerve cells. Adequate lecithin can improve the speed of information transmission and brain vitality, which is reflected in quick thinking and strong learning ability.
3. Lecithin is the main source of myelin sheath in the brain. Adequate lecithin can improve the accuracy of information transmission, which is reflected in concentration and memory enhancement.
Based on the above viewpoint, developed countries attach great importance to lecithin supplementation for pregnant women and infants. The 7th International Lecithin Conference once concluded: "To sum up these research results, it is very important for pregnant women to ingest a proper amount of lecithin, which is very important for children's intellectual development." The US Food and Drug Administration (FDA) also approved the appropriate supplementation of lecithin in all infant diets.
Food source of lecithin
Soybeans, egg yolks, walnuts, nuts, meat and animal offal.
Consequences of lack of lecithin
1, lack of lecithin during pregnancy will affect the normal development of fetal brain, even abnormal development.
2. The lack of lecithin in infants and young children affects the development of brain and intelligence, and reduces the learning ability.
3. Adults and middle-aged and elderly people lack lecithin and are prone to hyperlipidemia and atherosclerosis.
4, lack of lecithin, but also make the brain in a state of fatigue, mainly manifested as: psychological tension, slow response, dizziness and headache, insomnia and dreaminess, distracted thinking, memory loss, forgetfulness, difficulty in concentration and so on.
What is the function of lecithin? 2 What food contains lecithin?
If you want to get enough lecithin to lose weight, you don't have to take nutritional supplements. Many natural foods, such as soybean, wheat germ, sunflower seeds, egg yolk, milk, animal offal, seafood and edamame, also contain lecithin. Therefore, as long as girls maintain a balanced diet, they will not lack lecithin in theory. Even if they realize that they lack lecithin, they only need to eat more of the above foods and increase the intake of lecithin.
In addition, the intake of lecithin should also be selected according to the needs of the body. If you want to improve the health of the brain, lecithin in egg yolk is the most effective. Lecithin in egg yolk can emulsify cholesterol into smaller molecules, which can be absorbed by tissues after blood circulation. The most important thing is that it will not increase cholesterol in plasma. On the contrary, if you want to play the role of lecithin in lowering blood fat, you can consider taking soybean lecithin, because phosphatidylcholine contained in soybean lecithin is an unsaturated fatty acid, which can soften blood vessels and reduce the problem of hypertension caused by thick blood fat.
Can eating lecithin-related products reduce weight have side effects?
The weight-reducing effect of lecithin has not been recognized by the scientific research community, but the US Food and Drug Administration (FDA) has confirmed that lecithin is a safe food, and there will be no serious side effects as long as it is taken according to the recommendations. However, because some lecithin-related products are made from soybeans, people who are allergic to soybeans may have serious and excessive reactions, such as rash, diarrhea and stomachache. Under these special circumstances, girls should stop taking it immediately and seek the assistance of medical staff.
In addition, lecithin-related health care products may conflict with some drugs. For example, don't mix lecithin-related health care products with drugs for treating glaucoma and xerosis. In addition, lecithin may increase platelet adhesion, and women who are using anticoagulant drugs should pay more attention.
How much lecithin do you need to eat every day?
Although the role of lecithin in weight loss has not been scientifically recognized, it is no problem for girls to supplement lecithin in their daily diet for health reasons, but the only thing to note is that the daily intake must be controlled. The US Food and Drug Administration (FDA) suggests that people should take lecithin in their diet in a natural way. According to a large-scale clinical epidemiological study, the daily intake of lecithin should not exceed 5 grams, so girls should also pay attention to the relevant weight when choosing lecithin-related health care products, and the right amount is better.
