What lecithin is

The biological name of lecithin is phosphatidylcholine, which is the highest content of phosphine in human tissues, is an important component of nerve tissue, and belongs to the highest level of neurotrophinia. Lecithin accounts for about 1% of body weight in the human body, but it accounts for 30% of brain weight in the brain; and in brain cells, it accounts for 70 to 80% of its dry weight. Lecithin is concentrated in the brain and nervous system, blood circulation system, immune system and heart, liver, lungs, kidneys and other important organs.

Lecithin, known as the "third nutrient" juxtaposed with protein and vitamins, is the highest content of phosphine in the human body, is an important component of nerve tissue, belongs to the highest level of neuronutrients, concentrated in the human brain and nervous system, blood circulation system, immune system and heart, liver, lungs and kidneys and other important organs.

Although it is only about 1% of the body, it accounts for one-third of the person's key parts of the brain, and even higher in brain cells, with a proportion of 70 to 80%.

Because of its important proportion in the brain, it is not difficult to imagine the important role it plays.

1. Lecithin can ensure the health of the brain cell membrane, help it play a normal role, ensure the nutritional input and waste output of brain cells, and protect its healthy development. Therefore, for fetuses in the critical period of brain development, lecithin is the most critical and important nootropic nutrient.

2. Lecithin is an important source of information transmission media between nerve cells. If a person's brain lecithin is very sufficient, then the speed of its information transmission, the vitality of the brain is faster than ordinary people, that is to say, the speed of thinking quickly, learning knowledge and accepting new things is faster.

3. Lecithin is also the main source of substances for the brain nerve myelin sheath. If there is sufficient lecithin, the accuracy of the information it transmits is high, that is, the memory is strong.

Pregnant women in the pregnancy of a new life, in a short period of time need to regenerate a large number of cells, if the pregnant woman's body lecithin is insufficient, the mother's amniotic fluid lecithin content is correspondingly insufficient, which will hinder the development of fetal cells, and there will be a variety of obstacles, such as fetal hypoplasia, congenital malformations, but also lead to miscarriage and premature birth.

Human brain cells are made up of about 15 billion cells, of which 70% of which are formed as early as the mother. Lecithin has the function of activating these brain cells. Therefore, adequate intake of lecithin during maternal pregnancy is an effective way to have a healthy and intelligent baby.

In addition, lecithin has a certain preventive effect on pregnancy poisoning that occurs in pregnant women due to elevated cholesterol and placental lesions.

Egg yolk lecithin is more easily absorbed by the human body, so that pregnant women can reduce pregnancy response, so that the fetal growth of amniotic fluid has sufficient lecithin concentration, promote the proliferation rate of fetal brain nerve fission, accelerate the assembly of the nervous system and the growth and development of various tissues and organs, prevent viral infection, prevent fetal malformations, increase the number of brain nerve cells by 1%, and make the baby born smart.

In addition, the mother will sharply reduce the lecithin content during childbirth, often leading to physical and mental abnormalities, followed by postpartum anxiety, hysteria, tooth loss, hair loss, etc., which are caused by insufficient lecithin or imbalance in hormone secretion. Therefore, it is necessary for pregnant women to supplement lecithin.

1. Lack of lecithin during pregnancy will affect the normal development of the fetal brain, and even abnormal development.

2. Lack of lecithin in infancy and early childhood, affecting brain and intellectual development, so that the learning ability declines.

3. Lecithin deficiency can also make the brain in a state of fatigue, mainly manifested as: psychological tension, slow response, dizziness and headache, insomnia and dreams, scattered thinking, memory loss, forgetfulness, difficulty concentrating and other phenomena.

Lecithin is mostly found in egg yolks, soybeans, fish heads, eels, animal liver, mushrooms, yams, sesame seeds, black fungus, safflower seed oil, corn oil, melon seeds, cereals and other foods, of which the highest content of egg yolks, soybeans and animal livers.

However, lecithin has a disadvantage, that is, it is not heat-resistant, its activity is most effective at about 25 ° C, above 50 ° C, it will lose its function. Therefore, this is the right father's cooking technology requirements, be sure to control the temperature within 50 ° C.

Although soybeans and eggs are rich in lecithin, their quality is high or low. Eggs have the highest quality lecithin, but are difficult to extract, making them comparable in price to gold.

Therefore, most of the lecithin on the market is extracted from soybeans. Each soybean contains about 1.3 to 2.1% lecithin, that is, if you need to take 3 grams of soy phospholipids per day, you have to eat five or six kilograms of soybeans.

Therefore, expectant mothers also have to take it from other foods.

Now, let's introduce you to a few:

1, use boiling water to rinse the egg flowers, and then add honey;

2. Soy milk. Warm soy milk to 80 ° C, then add an appropriate amount of honey;

3. Mix tofu;

4. Wood whisker meat;

5. Fish head soup. Cut the fish head into pieces, do not lose the fish brain and fish fat in it. First put ginger and garlic in a frying pan, fry until fragrant, then pour the fish head, fry it for a while, then pour boiling water, cook until milky, turn off the heat, add salt, monosodium glutamate and shallots and other spices.

In addition, you can also follow the doctor's advice and take lecithin-rich health supplements.
