What is lecithin extracted from

Lecithin is an essential substance in the human body, and many foods contain lecithin, so everyone should eat more foods high in lecithin, because lecithin is very helpful to the human brain. Especially students or working people who need to use their brains frequently should eat more lecithin to enhance their memory. How is the lecithin that can be eaten directly on the market extracted?

1. What is lecithin?

Lecithin, also known as yolk pigment, is known as the "third nutrient" alongside protein and vitamins. In 1844, the Frenchman Gohley discovered lecithin from egg yolk and named it Lecithos in Greek. The generic drug name is Lecithin.

The biological name of lecithin is phosphatidylcholine. It is the phospholipid with the highest content in human tissue, an important component of nerve tissue, and a high-level neuronutrient. Lecithin accounts for about 1% of the body weight in the human body, but accounts for 30% of the brain weight in the brain; and in brain cells it accounts for 70-80% of their dry weight. Lecithin is concentrated in the brain and nervous system, circulatory system, immune system, and important organs such as the heart, liver, lungs, and kidneys.

2. The role of lecithin:

1. Lecithin can protect the health of brain cell membranes, help them function normally, ensure the nutrient input and waste output of brain cells, and protect their healthy development. Therefore, for the fetus in the critical period of brain development, lecithin is the most critical and important brain-enhancing nutrient.

2. Lecithin is an important source of information transmission media between nerve cells. If a person's brain has sufficient lecithin, then the speed of information transmission and brain activity will be faster than that of ordinary people, which means that the person will think quickly and learn knowledge and accept new things quickly.

3. Lecithin is also the main source of myelin sheath in the brain. If there is sufficient lecithin, the information transmitted will be more accurate, which means the memory will be stronger.

Substances rich in lecithin:

Lecithin is mostly found in foods such as egg yolk, soybeans, fish heads, eels, animal livers, mushrooms, yam, sesame, black fungus, safflower seed oil, corn oil, melon seeds, and cereals. Among them, egg yolk, soybeans, and animal livers have the highest content.

Although soybeans and eggs are rich in lecithin, their quality varies. The lecithin in eggs is of the highest quality but is difficult to extract, making its price comparable to that of gold. Therefore, most lecithin on the market is extracted from soybeans. Each soybean contains about 1.3-2.1% lecithin, which means that if you need to consume 3 grams of soybean lecithin every day, you have to eat five or six kilograms of soybeans.
