Lecithin powder is a dietary supplement whose use is beneficial for health purposes but not for sports or physical training.Nutrition with powdered lecithin is designed to reduce the intestinal absorption of cholesterol (intervention necessary to fight the lipid dismetabolisms of this steroid molecule).Lecithin powder is a supplement whitch meets all the basic criteria to be defined as a dietary supplement. It is a product that increases the nutritional intake of one or more useful or essential molecules (if associated with vitamins and minerals), if lacking in the diet or simply useful for the organism.
The powdered lecithin has no side effects and, if taken in conditions of hypercholesterolemia,improves health status. What is lecithin? Lecithin is a Phospholipid, i.e. a molecule that has chemical affinity for lipid and water. Thanks to this feature, lecithin is a potent EMULSIFIER that, within the intestinal lumen, binds cholesterol andhindertheuptake.In our organism lecithin performs two important functions: it is the main component of the cell membrane and it is a substrate for the synthesis of hepatic enzyme Cholesterol Acyl Transferase Lecithin (LCAT) NB. The LCAT DEFICIENCY determines the esterification of cholesterol and therefore it promotes tissue distribution; In addition, improves uptake of HDL that implement the "reverse transport of cholesterol" promoting the elimination with bile, then with feces.
Why-when-how to take powdered lecithin
Powdered lecithin is a useful supplement for the reduction of blood cholesterol. This role is derived from its ability to bind dietary cholesterol in the intestinal lumen, reducing the absorption, both from increased hepatic synthesis of LCAT, an enzyme essential to"reverse cholesterol metabolism".Taking powdered lecithin is useful (and therefore recommended) if the blood cholesterol levels excessively stand out from the norm; We recall briefly that for healthy people the boundaries of normality are roughly: total cholesterol: 200-220mg/dl (desirable values less than that threshold) HDL: 50 mg/dl; Male HDLS < 40 mg/dl (desirable values above that threshold) LDL: Stryker/dl (desirable values less than that threshold) remember that, especially in the presence of other risk factors for vascular pathologies (atherosclerosis with coronary infarction or stroke), these limits can also be significantly corrected. In particular, are modifiable risk factors and aggravating the hypercholesterolemia: cigarette smoke, hypertension,obesity,sedentary lifestyle and diabetes mellitus. Obviously, the powdered lecithin is not the only source of this Phospholipid; It is of course content in food products of plant origin (soybeans and legumes, whole grains), but also in those of animal origin (egg yolk [from which it was retrieved for the first time in 1850], and meat); However, his dietary intake is higher and more effective if you favorite legumes and cereals in relation to animal food sources. This is due to the fact that, by binding fats and cholesterol, lecithin contained in foods of animal origin may already be saturated or not sufficient to hinder considerably the absorption of most of the steroid content in them ... also, take lecithin to fight cholesterol by eating foods which are rich ... for logic, doesn't seem a particularly brilliant strategy! On the other hand, regularly eating legumes and whole grains, as well as encouraging the fiber intake which in turn fights the absorption of fats, it is possible to obtain a source of lecithin rich and more "pure" (no cholesterol). It is true that lecithin has the power to bind all vegetable fats and phytosterols, however, their concentration is lower than in food of animal origin while the amount of lecithin is absolutely more.
Lecithin powder should be taken in conjunction with the main meals, especially those that have a substantial proportion of cholesterol or saturated fatty acids. The recommended daily intake ranging between 5 and 15 g/day, possibly broken down into 2 or 3 times (lunch-dinner or breakfast-lunch-dinner); powdered lecithin is also water soluble, therefore it is recommended to dilute 1 full teaspoon (5 g) or 1 tablespoon full (10 g) each 100-150 ml of water.
