Lecithin is derived from the Greek word for egg yolk (lekithos), with a high amount of lecithin in the egg yolk. Naturally, lecithin-rich foods have a high fat content; like eggs, beef liver. But peanuts, beef, some fruits and vegetables contain less lecithin.
The E codes (EC Code) are the code numbers for each food additive set by the European Union.Food additives are used in the definition of all kinds of food in order to ensure integrity throughout the world. Each food item has an E code. The letter E stands for “Europe”.
E322 Lecithin is an emulsion obtained from soybean, egg yolk, peanut, corn or animal sources. Emulsifiers prevent oil from separating from the water phase. . It is not toxic but overdose disrupts the stomach, cuts the appetite and causes sweating. margarine, chocolate, mayonnaise and milk powder is used to provide the composition of oils. Herbal type should be preferred.
Lecithin is also called phosphatidylcholine. Lecithin is produced as a by-product during the production of flour from soybean sprouts or during the production of soybean oil from soybean plants and contains glaucolipids, triglycerides and phospholipids. Phospholipids are the building blocks in the cell membrane that all cells in the body need. Phospholipids prevent cell membrane hardening. Lecithin protects cells against oxidation and acts as the protective membrane surrounding the brain in humans.
Lecithin is also sold in the form of soft gelatin capsules or granular powders and is consumed for various health reasons because it is believed to lower cholesterol, strengthen memory, improve liver function among the population. The effect of lecithin in lowering cholesterol in humans was investigated. However, in a review published in the American Journal of Clinical Nutrition in 1989, examining the results of 24 studies, there was little evidence that lecithin directly reduces cholesterol (Knuiman et al., 1989).
There are also studies on the effects of lecithin on memory functions. There is no certainty that lecithin improves memory, because inconsistencies have been observed in human studies. Other potential benefits of lecithin are its role in liver and reproductive health, as well as in improving physical performance in certain activities. Further research is needed to confirm these health effects of lecithin.
