Functions of Cholesterol: Cholesterol is essential to life for its many functions: Structure: cholesterol is a major component of plasma membranes of animals (not present in the vegetables). Although cholesterol is found in small amounts in cell membranes in the cytoplasmic membrane are in a 1:1 molar ratio relative to phospholipids, regulating their physicochemical properties, particularly fluidity. However, cholesterol is found in very low proportion or are virtually absent in subcellular membranes. Precursor of vitamin D is encial in calcium metabolism. Precursor of the sex hormones progesterone, estrogen, and testosterone. Corticoesteroidales precursor hormones: cortisol and aldosterone. Precursor of bile salts: the absorption of essential nutrients and lipid main route for excretion of body cholesterol.
Precursor of lipid rafts. What is it and how much control the excess cholesterol blood cholesterol (hypercholesterolemia), such as obesity, lack of exercise, high blood pressure and snuff, facilitate suffering from severe circulatory diseases. If several of these factors add up in one person, predisposition to disease is triggered above is much higher. should take into account these other “risk factors” Although today the word ‘cholesterol’ is full of negative connotations associated with a poor diet and obesity cardiovasulares problems, in reality it is a necessary element for our body. The important thing is to know what it is, how it works and when it is injurious to health.
Cholesterol is not nothing but a type of fat, a lipid specifically involved in many important physiological processes such as cellular, digestive and synthesizing hormones, among other functions. Our liver is capable of producing the cholesterol necessary for the body. However, through food, we receive an additional quantity of this substance which, in many instances, is detrimental to health, especially for the heart. The origin of the increase in blood is derived mainly from the increase of the unsaturated fats in the diet, from foods with fat. What should I eat if I have high cholesterol in these cases, once the doctor detects an excess of this substance in the blood, usually puts the patient on a restrictive diet with fat intake. Experts recommend not only make life less sedentary, but to improve the diet with increased consumption of fruits and vegetables rich in nutrients, fiber and fat free. Also, eating more foods with unsaturated fats such as fish, skinless chicken-and-vegetable oils such as olive and seed (corn, sunflower). They should not miss high-fiber whole grains and cereals, rice, beans and pasta. It usually suppress all foods with saturated fats: red meat, pork, lamb, cold cuts, cheese and butter fat. Products with excess sugars and calories are also deleted (chocolate, pastries, sauces, pates), and those that are direct sources of cholesterol, egg yolk, some offal and shellfish. Excess salt and spices also should be avoided. And with it, preserved and prepared to abuse these seasonings. Although not removed from the diet, we recommend moderate consumption of coffee, tea, soft drinks and milk (preferably skimmed use only). We must also get used to drink lots of water throughout the day and needed in food and chew slowly and salivate well.
