Fat-like compounds play a key role in the metabolism of humans and animals. Phosphatidylcholine, or lecithin, is an ester in which choline phosphate takes the place of a fatty acid. Lecithins are a mixture of phospholipids, free carboxylic acids and fats.
A vital substance is involved in the work of the brain, conducting nerve impulses, detoxifying metabolic toxins, and prevents the deposition of cholesterol on the walls of blood vessels. The emulsifying and fat-burning effect of phospholipids is used for weight loss.
What is lecithin?
In medicine, complex preparations are used, consisting mainly of phospholipids, which are called lecithins.
- phosphatidylethanolamine or cephalin;
- free carboxylic acids;
About two thirds of the body's phospholipids are in the liver.
To whom is lecithin indicated and contraindicated?
Phospholipids carry out life support functions.
Drugs are prescribed according to the following indications:
- Atherosclerosis. Cholesterol deposits dissolve. The walls of the vessels that feed the myocardium are cleaned.
- Alzheimer's disease. Patients feel better.
- Hepatic pathology. Choline has a hepatoprotective effect, removes toxic metabolites, and starts the process of burning excess fat.
- Stressful conditions. The phospholipid complex acts as an adaptogen.
- Intestinal disorders. Mucosal lipids are 70% phosphatidylcholine.
- Drug and alcohol intoxication.
- Mental disorders, pathologies of the nervous system.
- Kidney disease.
- Rehabilitation after operations or past illnesses.
- Diseases of the skin and hair.
Preparations containing phospholipids have the following contraindications:
- individual intolerance to components;
- increased blood coagulation;
- pregnancy and lactation - the effect of the drug on the fetus and baby is not well understood;
- pancreatitis, cholecystitis;
- gall bladder stones;
Attention! The supplement contains estrogens that reduce potency in men.
An overdose should not be allowed, the symptoms of which are vomiting, diarrhea, headaches. It is forbidden to take nutritional supplements unnecessarily.
Daily lecithin requirement
The daily dose of lecithin is prescribed by the doctor. The needs of the child depend on body weight and are 1-4 grams per day. The lack of biologically active substances adversely affects the mental development of children. Adults require 5 to 6 g / day. Part of the phospholipids comes with food.
The missing amount is taken with a food supplement. A portion is crushed into 3 doses, consumed with food, washed down with water. The duration of diet therapy ranges from 3 months to several years.
Lecithin for weight loss: how to take
The mechanism of fat burning action is as follows:
- Emulsifying effect. The breakdown of large molecules is accelerated.
- Production of heat products. Fats are extracted from the depot, used to generate energy.
- The acceleration of metabolism.
- Dulling hunger.
The effect of taking the supplement is possible only with a balanced diet, combined with physical activity.
A person seeking to lose weight eliminates the following foods:
- White bread;
Drinking plenty of water helps to achieve the desired result.
Lecithin is available in the following therapeutic forms:
- powder or granules;
In capsules and tablets
A capsule or pill contains from 1.0 to 1.5 g of the active ingredient. The medicine is taken with food in the morning or in the evening. Wash down with sugar-free liquid. The dosage for children is determined by the doctor.
A food supplement is consumed twice daily per teaspoon, which corresponds to 2.5 g of phosphatidylcholine. Food should not be hot.
Gel and solution
Dosage forms are intended for children over 3 years of age and primary school students. Daily portion - 2 scoops, which are equipped with packaging.
A fortified solution has the appearance of a vegetable oil. It is taken 1 tablespoon with vegetable salads or mixed with milk or juice.
Which lecithin is better: soy or sunflower
Leading positions in the market of dietary supplements are occupied by lecithins isolated from the sediment of vegetable oils. Soy phospholipids are included in many foods - margarine, cooking fats, spreads, and confectionery. Components for the manufacture of drugs are recovered from soybean oil.
The competition for lecithin isolated from beans is sunflower phospholipids. The main advantage for Russian consumers is that the leading oilseed crop is not soy, but sunflower.
Soy lecithin revealed the following disadvantages:
- Allergy develops more often than on sunflower.
- The oil obtained from legumes contains phytoestrogens - substances that are similar in structure to female sex hormones. Therefore, the inhibitory effect of soya lecithins on men's health cannot be ruled out.
- Most soybean varieties have been genetically modified. The harmfulness of GMOs has not been proven, however, among Russian consumers, the presence of modified components raises concerns.
- The cost of a sunflower preparation is higher. However, comparing the advantages and disadvantages of products with similar qualities, consumers prefer domestic products.
What foods have lecithin in?
Many phospholipids contain foods rich in fats or fat-soluble vitamins. However, small amounts of lecithins are found in fruits and vegetables.
Among plant sources of the substance, the following products are distinguished:
The highest concentration is different for the listed products of animal origin:
- dairy products;
- egg yolk;
- kidneys are chicken.
Sunflower lecithin: benefits and harms
Sunflower is the leading oilseed crop in Russia. By-products of oil extraction industries are phospholipids, from which lecithin is extracted.
Clinical studies of the Russian Academy of Medical Sciences have proved the effectiveness of using a food supplement for the treatment of diabetes mellitus, pancreatitis, diseases of the heart, liver, and intestines. Lecithin relieves stress and helps get rid of extra pounds. Harm arises from violation of the rules for the use of food additives.
