What is lecithin? You are probably familiar with the word. In fact, you may even be taking it as a supplement. But what is lecithin really? Where does it come from? And what can it do for you? ‘What is lecithin?’ and other such questions are what we are going to tackle in this article.
What is Lecithin?
Actually the term lecithin connotes two meanings that are somewhat related but are not used in the same sense. In biochemistry and other related science, lecithin is a synonym for phosphatidyl choline. It is the main lipid component in biological membranes, like our cell membranes or cell walls of plants. On the other hand, commercial lecithin is actually a natural mixture of neutral and polar lipids, including glycolipids, triglycerides, sterols, and small quantities of fatty acids, carbohydrates, and sphingolipids. The polar lipid Phosphatidyl choline is present in commercial lecithin in concentrations of 20 to 90%.
Where does lecithin come from?
After asking what is lecithin, you want to know where it is found. Lecithin that contains phosphatidyl choline is produced mainly from vegetable sources, although it may also be found in animal and microbial sources. Majority of commercial lecithins sold in the market today come from soybean (mostly), sunflower, and grape seed. When talking about plant lecithins, the most common source is soybean.
When Maurice Gobley, the French scientist discoverer of lecithin, found lecithin in egg yolk in 1950, egg yolk was the sole source of lecithin used by the commercial food industry. However, by the 1930s, the time when soybean lecithin was discovered, egg yolk no longer held its former place of being the major source of lecithin for commercial use. Today, it is not even a major source of lecithin in nutritional supplements. The reason may be that lecithins that come from plants are GRAS or generally regarded as safe.
Who needs to take lecithin?
When you know all there is to know about what is lecithin, then you probably know already that the substance is synthesized by the body from food. This means that it is not an essential nutrient, since the body can always get its supply of lecithin from its diet. This is also one of the reasons why hardly anyone ever suffers a deficiency in lecithin. Still, having a steady supply of lecithin for our body’s use is good, if only to take advantage of the benefits it has to offer.
Lecithin is naturally found in the foods that we eat, especially rich foods, such as egg yolk, soybeans, grains, wheat germ, fish, legumes, yeast, peanuts, etc. The compound can also be found as supplement sold to the public. Lecithin capsules, powder, or granules are sold in many food and drug stores, often marketed as weight loss promoting supplements for dieters and weight loss enthusiasts. In addition to that, lecithin is also taken in a pill form or mixed into health shakes.
What is lecithin’s claim to health?
The following are some of the many health claims that lecithin is said to have:
* Cardiovascular health
* Liver and cell function
* Fat transport and fat metabolism
* Reproduction and child development
* Treatment for gallstones
* Improvement in memory, learning and reaction time
* Healthy hair and skin
* Cell communication
* Physical performance and muscle endurance

Lecithin Sources
... the body, we need to turn to other lecithin sources, over and above the normal diet. Soy Foods One of the most popular lecithin sources is soy. In fact, most lecithin sources sold commercially today are derived from soybean oil. In the United States, soy food consumption is increasing annually. This may help to increase the level of lecithin consumption. Soy food is one of the most versatile of lecithin sources. The soybean can be eaten whole after it has been boiled or roasted. It can also be transformed into a great variety of foods, the more popular of which are tofu, meat alternatives, soy sauce, soy flour, and soybean oil (usually called vegetable oil). Supplements Another alternative to getting adequate supply of lecithin is supplementation. Supplements are excellent lecithin sources; one tablespoon of lecithin granules contains as much as a 1, 725...
Lecithin Benefits
... a powerful emulsifier, there is more to lecithin benefits than that. For decades, people have been touting that treatment for high cholesterol is one of the many lecithin benefits. There is little evidence to support this claim, mostly because when the studies conducted were largely unreported. Still, these claims about lecithin benefits on high cholesterol may have something to do with the fact that lecithin, specifically phosphatidylcholine, appears to have the ability to disperse cholesterol in the blood, thus keeping them from sticking to the walls of our arteries. In doing this, lecithin may also help prevent atherosclerosis. Another one of the lecithin benefits is that it displays potential as a remedy for various psychological and neurological diseases, such as Tourette's syndrome, Alzheimer's disease, and bipolar disorder (also known as manic depression). The claim is based on the significant role that lecithin plays in nerve cell signaling as well as in synthesizing important neurotransmitters such as acetylcholine, without which many of our...

Structure of Lecithin
... was first discovered in 1846 when French scientist Maurice Gobley separated the nutrient from egg yolk. In 1850, he gave it the name lekithos, which is Greek for "egg yolk." But by the 1930s, majority of the lecithin sold commercially was derived from soybean oil. The nutrient was found as a by product of the degumming process of soybean oils. The Structure of Lecithin: Egg Yolk There are differences in the structure of lecithin derived from egg yolk and those derived from plants, such as soy lecithin. First, the structure of lecithin derived from egg What is Lecithin yolk is essentially composed of triglycerides and phospholipids, which differs considerably from plant lipid mixtures. Egg yolk lecithin contains long chain polyunsaturated fatty acids known as LC-PUFAs or Arachidonic Acid and Docosahexaenoic Acid. Both are bound phospholipids, the former occurring exclusively in cell membranes while the latter is found in high amounts in optic nerve membranes. In the structure of...

... or animals. The term is often synonymous to phosphatidyl choline (PC), which many in the scientific community use to refer to lecithin. Lecithin, the Emulsifier One of the many functions of lecithin is emulsifying fats. In the body, lecithin is present in bile, a digestive substance produced by the liver and stored in the gall bladder to aid in digestion. It is critical for the absorption of fats and fat-soluble vitamins in the small intestine and serves as a major route for eliminating cholesterol. The presence of lecithin in bile is primarily to keep the fatty acids from mixing with other organic molecules also found in bile, such as bile acids, cholesterol, phospholipids, and bilirubin. By acting as an emulsifying agent, lecithin ensures that bile does all its functions smoothly. Lecithin, the Aid to Fat-Burning...

... connection between improved conditions and the taking of lecithin supplements. Instead, what doctors have observed is a concerning number of reports of soy lecithin allergens. Soy Allergy In line with the increasing use of soy products today, soy lecithin allergens also arose and allergic reactions arose. It was in the early 1980s that Stuart Berger, MD, labeled soy lecithin allergens as one of the top seven allergens - sometimes known as the "sinister seven." Besides soy lecithin allergens, other allergens that are considered What is Lecithin part of the "sinister seven" are peanuts, tree nuts, milk, eggs, shellfish, fin fish, and wheat. Allergies are a result of an oversensitized immune system that once exposed to a certain type of allergen, such as soy lecithin allergens, reacts by producing vast amounts of antibodies, known as immunoglobulin E (IgE). This results in reactions which may include coughing, sneezing, runny hose, hives, diarrhea, facial swelling, shortness of breath, a swollen tongue, difficulty swallowing, lowered blood pressure, excessive perspiration, fainting, anaphylactic shock, or...

... industry as well as other industries. However, for the most part, liquid lecithin is utilized as an emulsifier, and is in fact one of the limited number of emulsifiers commonly regarded as safe to use. Benefits While lecithin is a natural part of the body, it is, however, not an essential nutrient, unlike fatty acids or amino acid. Our bodies already have lecithin and can manufacture more if needed. What is essential however is the synthesized form of liquid lecithin, which is choline. Our bodies derive choline from phosphatidylcholine component in liquid lecithin. To maintain cell membrane integrity and facilitate the movement of fats in and out of cells, as well as ions, wastes, and nutrients, we need a constant supply of choline. In addition, the neurotransmitter acetylcholine needs choline for its normal functions. Due to liquid lecithin's choline...
Health Lecithin
... liver and heart health. However, these health lecithin benefits are but the What is Lecithin tip of the iceberg. As more and more researchers are focusing much of their time and energy on investigating the compound, more and more of the health lecithin benefits may be uncovered. Where Lecithin Comes From Lecithin is found in many of the foods we have for our daily diet. However, if you want foods that are rich in lecithin, then turn no further from those same foods that are high in cholesterol and fats. The most concentrated sources of dietary lecithin are organ meats, red meats, and eggs, which is where lecithin got its name by the way - lekithos, Greek for "egg yolk." But with today's current trend in low-fat, low-calorie diet, many have turned away from lecithin-rich foods. This reduction may likely result in an inadequate dietary intake of lecithin and choline, a component of lecithin. In order to make up for the lecithin lost through reduction...
Benefits of Lecithin
And to top it all off, it adds sprinkle to your salads, favorite drinks, nut butter, spreads or sauces. Yet, for all the wonderful benefits of lecithin, would you believe that it is actually nothing more than a byproduct of soybean processing? Byproduct, meaning it is little more than What is Lecithin waste. So how come this purportedly "waste" product contains so many health benefits? What is the theory behind the benefits of lecithin? Lecithin - Its History and Origin The word lecithin comes from the word lekithos, which is Greek for "egg yolk." It was given that name because lecithin was actually first discovered in 1805 when the French scientist Maurice Gobley isolated the compound from an egg yolk. Lecithin is a great emulsifier. Since its discovery, it has been widely marketed in the commercial sector as an emulsifier...

... from the foods we eat. A deficiency in this compound could lead to various debilitating diseases, not least of which is cirrhosis of the liver. The good thing about it is that phosphatidyl choline is normally synthesized by the body to form choline, so taking in lots of lecithin supplements containing a high percentage of the compound could help boost your supply of choline and overcome a potential deficiency. Lecithin supplements are one of the few emulsifiers approved by the United States Food and Drug Administration as GRAS or Generally Recommended as Safe for consumer use. There are no Recommonded Dietary Allowances for lecithin supplements; however some scientists do recommend an Adequate Intake for choline. For men, 550 mg is often recommended as adequate for daily What is Lecithin use while for women, 425 mg is needed. Both choline and lecithin supplements are available in the market. However, if you want the most effective way to elevate your choline levels, the intake of lecithin supplements is...
Soy Bean Lecithin
... replace egg lecithin as being the major source of this compound. Soy bean lecithin is composed of three types of phospholipids: phosphatidylcholine (PC), phosphatidylehtanolamine (PE), and phosphatidylinositol (PI). The most important is phosphatidylcholine which, when synthesized, becomes choline, an essential nutrient that is desperately needed by the body. Phosphatidylcholine contributes to the structural integrity of the cell. Being a major component of the cell membrane, it also helps facilitate the movement of fluids in and out of the cell as well as eases cell signaling or communication. It is particularly important in such What is Lecithin vital organs as the liver and the brain. Choline helps synthesize acetylcholine, a neurotransmitter responsible for much of our cognitive functions. Because of this unique function of choline, many scientists believe that supplementing our choline supply by taking soy lecithin may...

The U.S. Food and Drug What is Lecithin Administration has tagged lecithin as one of the few emulsifiers that is safe for use by consumers. But while soy lecithin is more popular for its emulsifying properties, it has more to offer. Its unique lipid molecular structure makes it useful for pharmaceutical and cosmetic applications. In addition, it is also utilized for a variety of industrial purposes, including paints, textiles, lubricants, and waxes. Lecithin is also considered as having beneficial effects to our health. The substance actually contains three types of phospholipids: phosphatidylcholine (PC), phosphatidylethanolamine (PE), and phosphotidylinositol (PI). Phosphatidylcholine contains the element choline, which is essential to every living cell in the body and is one of the main components of cell membranes. It seems majority of the...
