There is no denying the now established fact that soya is good for the health. Not only is it a good source of proteins, it also contains isoflavones genistein and daidzen, all of which contribute to its health-promoting goodness. Recent studies have also shown that soya contains a significant amount of antioxidants, which are chemical substances that help destroy disease causing free radicals.
Nearly all aspects about soybeans have already been studied to determine why this small legume is so beneficial. From tofu to miso to shoryu, soybeans have been consumed widely because it is generally considered as good for the body. But one aspect of soybeans that is only gaining some attention is the presence of soya lecithin.
Admittedly, soya lecithin is not a novel idea. In fact, the first time that lecithin was extracted from soya was in the 1930s. Until that time, the commercial industry derived lecithin from egg yolks. But soon it was discovered that the by product of soybean processing contains substances, which when synthesized yields a surprising amount of soya lecithin. Today, majority of the commercial lecithin we find sold in stores are derived from soybeans.
Soya Lecithin - Its Composition
The term “lecithin” is a generic word used to refer to either phosphatidylcholine (PC) or a group of phosphate acids. Soya lecithin is typically the commercial kind, which consists of three types of phospholipids: phosphatidylcholine (PC), phosphatidylethanolamine (PE), and phosphatidylinositol (PI). All of these phospholipids are a major component in the formation of cell membranes, along with cholesterol and glycerides.
Soya Lecithin - Its Benefits and Functions
Since its discovery in 1850 by Maurice Gobley, lecithin has been used in a wide variety of food and industrial applications. Decades later, soya lecithin was discovered and the substance became a multifunctional, flexible and versatile tool best known for its emulsifying properties.
Soya lecithin helps promote solidity in margarine and give consistent texture to dressings and other creamy products. It also used in chocolates and coatings and to counteract spattering during frying. In addition, soya lecithin boasts of a unique lipid molecular structure which makes it idea for pharmaceutical and cosmetic applications and various industrial uses such as paints, textiles, lubricants, and waxes.
But while soya lecithin has many functional benefits, recent studies have been focusing on its purported health benefits. There is no arguing that lecithin, or more accurately phosphatidylcholine plays a significant role in the cell. It contributes to its structural integrity, facilitate the movement of fluids in and out, and eases cell communication. Its presence and its perceived role in brain functioning has led many scientists to surmise that lecithin may aid in brain-related disorders, including dementia, memory loss, Alzheimer’s disease, and many others.
Lecithin is also said to help keep the liver healthy. By keeping fats dispersed in the water, lecithin prevents these fats from accumulating in the liver, thus helping put a stop to some of the causes of cirrhosis.
But while phosphatidylcholine and its synthesized form, choline, seem to accomplish all these, studies have failed to make a significant connection between the intake of soya lecithin and treatment of these symptoms.

Soy Lecithin Allergens
... presence of lecithin in every cell of the human body as a major component of the cell membrane has led many scientists to conduct investigations on the role of lecithin in the normal bodily processes. It was found that a component of lecithin, phosphatidylcholine and its synthesized form, choline, are vital to liver health in that they help keep fats in the bile and protect liver cells from the ravages of oxidation. Other studies also showed that choline may play a significant role in the synthesis of an important neurotransmitter, acetylcholine. This led others to believe that lecithin may help improve the cognitive functions of the brain, even going so far as to help enhance our memories. But while there are quite a number of studies that seem to show evidence of the benefits of lecithin, there is little in the way to show a real connection between improved...
Liquid Lecithin
... in the bile, which is a kind of substance produced by the liver and stored in the gallbladder necessary for digestion. As an emulsifier, the function of liquid lecithin is to separate the fatty acids Soya Lecithin in the bile and protect them from the ravages of oxidation. The compound also helps keep the liver cells healthy so they can continue doing their function of filtering and cleansing the blood of all toxins and harmful molecules. Sources Liquid lecithin can be found in nearly all kinds of food. But the richest sources of liquid lecithin are those that are high in fat and cholesterol, such as eggs, red meat, organ meat, etc. Soybeans are also good sources of liquid lecithin. In fact, majority of commercial lecithin sold in the market today are derived from soybean oil even as the...
Lecithin Sources
... the compound. To maintain adequate supply of lecithin in 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 Soya Lecithin 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 mg/serving. A soft gel capsule of lecithin supplement may contain less at 180 mg/serving. The concentration of...
What is 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 Soya Lecithin are some of the many health claims that lecithin is said to have: * Cardiovascular health * Liver and cell function...
Lecithin Benefits
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 Soya Lecithin 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...
Lecithin Effects
... a process called hexane extraction. Lecithin Effects as an Soya Lecithin Emulsifier The food industry is among the first industries that discovered the wonderful lecithin effects of this natural emulsifier. Since its discovery, it has been used in foods such as chocolate, cheese, margarine, and salad dressings. Acting as an emulsifier, the lecithin effects help mix fats with water and keep them from separating. When you place the chocolate bar in the freezer, the low temperature causes the lecithin effects on the fat to fall apart. That's why the fat rises to the surface, giving the chocolate that whitish tinge. Besides being found in egg yolks and soybeans, lecithin is also present in all living cells of the body. Lecithin is actually a complex mixture of phospholipids, the most important of which is phosphatidylcholine, which is the number one...
Facts about Lecithin
... mixture of phospholipids, glycolipids, triglycerides, sterols, and small quantities of fatty acids, carbohydrates, and sphingolipids. Its primary phospholipid components include phosphatidylcholine (PC), phosphatidylethanolamine (PE), phosphatidylinositol (PI), and phosphatic acid (PA). Now, since lecithin is present in the cells of all living organisms, you must think and believe that it is an essential nutrient. Certainly, that is what the adverts have been telling us. However, the facts about lecithin will tell you that the substance actually comes from the diet and is only Soya Lecithin synthesized in the body. Therefore, it is not an essential nutrient, although it may have some beneficial effects. As a phospholipid, the facts about lecithin will indicate that the substance is a major component in cell membranes. Lipids make the cell membrane semi-permeable - that is, it allows some substances in while keeping other substances out. With its main component of choline, lecithin facilitates the movement of fats in and out of cells, as well...
Lecithin Side Effects
... touted for years as a wonder food, replete with countless medical benefits, among them is having positive lecithin side effects on persons combating atherosclerosis, multiple sclerosis, cirrhosis of the liver, gall stones, psoriasis, eczema, scleroderma, anxiety, tremors, and brain aging. But what is lecithin? And why does it have all these lecithin side effects? Lecithin, the Chemical Lecithin is mainly made up of a compound called phosphatidylcholine, which is one of a group of fat soluble phospholipids within the compound. In chemistry, the word lecithin is even used interchangeably with phosphatidylcholine, though most commercial lecithins (especially those derived from soybean) contain only about 20% of the compound. The chemical substance lecithin is found in all living organisms, specifically comprising the cell membrane and other membranes of organelles inside the cell itself. It is also a major component of the myelin sheath, which is the thin...
Structure of Lecithin
... lecithin play a vital role during pregnancy and infancy. Since babies have only limited capacities, they need arachidonic acid and docosahexaenoic acid to synthesize fatty acids from their precursors. Structure of Lecithin: Soy Markedly different from egg yolk lecithin, the structure of lecithin derived from soy actually consists of three types of phospholipids: phosphatidylcholine (PC), phosphatidylethanolamine (PE), and phosphatidylinositol (PI). Since soy lecithin is obtained in the process of degumming crude soy oil, it contains minimal amounts of hydratable compounds (1.8%), comprised primarily of phosphatides. After going through the synthesizing process, the resulting structure of lecithin is 30-35% crude soy oil and 65-70% phosphatides. Oil can then also be removed completely with the addition of acetone. In the structure of lecithin derived from soy, the phosphatides consist of glycerides, which are the basic components of soy oil. However, instead of one fatty acid radical, this has been replaced with phosphoric acid. Now, this is different in the case...
Lecithin Weight Loss
... is a phospholipid, one of the many contained in the cell membranes of all living organisms, whether plants 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 Soya Lecithin 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 Another function of lecithin is to help burn...
Lecithin is Powerful
... lecithin in action for you. A Versatile Nutrient The purposes of lecithin in the commercial sector are varied. It is used as a natural emulsifier and/or lubricant and utilized as an important ingredient for products ranging from pharmaceuticals to protective coverings. But lecithin is powerful Soya Lecithin not only for these reasons. Lecithin is powerful because it is one of the important nutrients that make up the cell membrane found in the cells of every living organism on earth and plays a vital role in normal cell functions. Lecithin - Its Composition and Functions In biochemistry, lecithin is often used synonymously with another term, phosphatidylcholine, which is actually one of the three main types of phospholipids found in the phosphatide fraction isolated from either egg yolk or soy beans. On the other hand, the lecithin...
Health Lecithin
... 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 of egg consumption, organ meats, and red meats, health lecithin supplements are taken. Why is it Good? As a phospholipid, lecithin is both phosphorus and fats (lipids). As such, it is an excellent source of essential fatty acids, which are a part of each molecule. Because phospholipids are both fat loving (lipophilic) and water loving (hydrophilic), lecithin helps protect the cell's essential fatty acids, which are polyunsaturated and extremely vulnerable...
Benefits of Lecithin
... the waste products of soybean processing, a discovery that changed the whole face of commercial lecithin. Today, most of the commercial lecithin we find sold in the market come from soybeans. Lecithin - Its Benefits Lecithin is regarded in the scientific community as a synonym for phosphatidyl choline (PC), which is said to be the main compound responsible for all the benefits of lecithin, specifically its medicinal effects. When we consume phosphatidyl choline, the compound is broken down into the nutrient choline, which many consider as an essential nutrient. "Essential" because our bodies cannot manufacture their own supply of choline and instead we have to depend on the foods that we eat to maintain the right levels. Lecithin is an essential component in the cell membrane. In fact, it defines its structure. As such, one of the benefits of lecithin is to maintain the integrity of cell membranes, helping facilitate the movement of fluids inside and outside the cell. As a component of bile, lecithin keeps fats emulsified....
Lecithin Supplements
... agent used to keep butter, margarine, chocolate bars, etc. However, when talking about lecithin supplements, what people generally refer to is phosphatidyl choline, or more specifically its purified form, which is choline, a B-vitamin and an essential nutrient. There is much health benefit attributed to both phosphatidyl choline and choline found in lecithin supplements. The compound has been associated with treatments for a variety of diseases from lowering high blood cholesterol, to reducing heart attacks and stroke, atherosclerosis, dispelling symptoms of cirrhosis of the liver and gall stones, and improving memory loss. Lecithin supplements are even currently marketed as aids to weight loss. However, it should be noted that phosphatidyl choline itself is not an essential nutrient. Our bodies already have it and can produce more of it should the need arise. Choline, on the other hand, can only be derived from the foods we eat. A deficiency in this Soya Lecithin compound could lead to various debilitating diseases, not least of which is cirrhosis of the liver. The good thing...
Soy Bean Lecithin
... by the kidney, which contains toxins and other harmful substances. As Soya Lecithin such, soy bean lecithin came to 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 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 aid in brain related disorders, including dementia, memory loss, Alzheimer's disease, and many others. In the liver, the...
