? Lecithin is the scaffold of whole body cell membrane. In blood, lecithin also combines with cholesterol and neutral fat to form high density lipoprotein (HDL), which is recognized as a "grease carrier" and is responsible for "moving" excess cholesterol in blood and cholesterol deposited on blood vessel walls to the liver for degradation and excretion, purifying blood and cleaning blood vessels, and preventing cardiovascular and cerebrovascular diseases caused by arteriosclerosis.
? Choline in food mainly exists in the form of lecithin, and scientists have clear regulations on how much choline should be eaten every day.
He pointed out in the book Human Nutrition published by People's Health Publishing House:
The suitable intake of choline for adults is 550 mg/day. Because choline accounts for about 14% of phosphatidylcholine, the intake of phosphatidylcholine should be 4000mg/ day.
? In the case of reasonable diet, only 0.5 ~ 1.5 grams of phosphatidylcholine can be obtained from food every day, and more than 2.5 grams should be supplemented.
? Phospholipids extracted from soybeans contain about 23-28% phosphatidylcholine. To supplement 2.5g phosphatidylcholine, you need to take pure solid soybean lecithin10g.
One thing deserves everyone's attention:
Even the best lecithin capsules contain at least 40% solvent oil, and 1200mg lecithin capsules contain at most about 0.7g total phospholipids.
? By ingesting lecithin capsules, you need to eat more than 15 capsules a day to reach the total phospholipid intake of10g, and at the same time, you need to ingest too much solvent oil.
? Many lecithin capsule products only recommend taking 1 ~ 2 or 2 ~ 4 capsules a day, which is the main reason why many people have no obvious health care effect after taking lecithin capsules.
? If you have problems such as hyperlipidemia and high blood viscosity, you need to take more lecithin every day. 1998 "China biochemical drugs" magazine published the article "Effective dosage and main components of soybean lecithin in the treatment of hyperlipidemia", and summarized the clinical research results of three hospitals including shenyang military area command General Hospital. The main effective component of soybean lecithin for regulating blood lipid is phosphatidylcholine, and the minimum effective dosage of soybean lecithin for reducing blood lipid is 10g per day (containing about 2.5g phosphatidylcholine), which is taken continuously for more than two months.
? Authorities investigated various brands of lecithin products in the domestic market and found that the effective components were uneven.
