Lecithin is the name used for substances such as phosphatidylcholine , which are a wide range of lipids of animal and plant origin and which have the property of being saponifiable . That is, they hydrolyze within alkaline solutions, reacting to produce fatty acid esters (commonly known as “soap”).Substances such as phosphatidylcholine also have an emulsifying action in the mixture of poorly miscible substances, such as water and oil. The soy lecithin is extracted from the vegetable fat soy or soy, and is a fat yellowish-brown discolouration, obtained after several processes of use of the seed.Lecithin was isolated in 1846 by Theodore Gobley, a French pharmacist who managed to obtain this substance from egg yolk. Subsequently, after advancing knowledge in the field of chemistry, new sources have been found to obtain lecithin or phosphatidylcholine.

What is soy lecithin for?

Currently, one of the most common raw materials for obtaining lecithin is soy. It is therefore that soy lecithin is one of the most abundant, being used in the food industry and prescribed for different alternative medical treatments . Its emulsifying action allows the decomposition of fats and their better disposal, that is why it is used in arteriosclerosis.

Soy lecithin is used to:

  • Improve digestion
  • Down mass and no fat
  • Prevent stone formation
  • Avoid cardiovascular diseases
  • Emulsify substances in food

Helps improve digestion

The consumption of processed foods that contain soy lecithin improves the breakdown of fatty foods, allowing easier digestion and eliminating the prolonged feeling of heaviness.

It serves to lose weight and lose weight

Soy lecithin participates in the metabolism of fats, thanks to its emulsifying properties, which hydrolyze its molecules. The consumption of lecithin is recommended in diets and regimes aimed at reducing body fat and measures in the body.

Used to prevent stone formation

Soy lecithin helps solubilize fats.

The consumption of soy lecithin favors the work of the bile to break down fats such as cholesterol, which are ingested, and those that are part of the bile itself, preventing accumulations and gallstones from forming.

The cholesterol contained in the bile tends to form crystals, which cause intense pain when trying to exit through the bile ducts. The consumption of lecithin improves the transit of bile through these ducts, degrading the fats that could be stored and causing plugging.

Avoid cardiovascular diseases

The frequent consumption of lecithins is recommended for the prevention of conditions such as arteriosclerosis and other conditions caused by excess arterial cholesterol.

Emulsify substances in food

One of the functions of soy lecithin is as an emulsifier in various food products. It works by mixing the particles of substances that would not otherwise combine, such as water and oil in mayonnaise.

Does consuming soy lecithin have side effects?

There are adverse effects from the consumption of soy lecithin, and they can occur in cases such as:

  • Soy lecithin intolerance
  • Overdose, especially when soy lecithin-based supplements are consumed uncontrollably

It should be noted that cases of overdose due to consumption of soy lecithin have increased in recent years, due to the fact that it has begun to be treated as a “miracle product” by traditional medicine and alternative methods, which are based on in unsupported beliefs and not in scientific studies.
