About Cholesterol
Generally know, lipids are divided into two categories. Fat (primarily triglycerides) is the most abundant lipids in the human body is a major source of energy for the body; another called lipids, are basic components of the biofilm, accounting for 5% of body weight, in addition to including the phospholipid glycolipids, there are very important called cholesterol. Cholesterol, also known as cholesterol. A cyclopentane derivative of the Philippines and more hydrogen. Early in the 18th century found that people from cholesterol gallstone, a chemist in 1816 with the Marshall lipid nature of this kind of material called cholesterol. Cholesterol exists in animals, particularly brain and nerve tissue is most abundant in the kidney, spleen, skin, liver and bile levels are high. Similar to its solubility and fat, insoluble in water, soluble in ether, chloroform and other solvents. Cholesterol is essential for animal tissue cells is an important material, it is not only involved in the formation of cell membranes, and the synthesis of bile acids, vitamin d and the raw material for steroid hormones. High-density cholesterol is divided into two kinds of cholesterol and LDL cholesterol, the former has a protective effect on the cardiovascular, often called "good cholesterol", which is high, will increase the risk of coronary heart disease, often called " bad cholesterol. " Per unit of cholesterol in the blood at 140 ╠ 199 milligrams, is relatively normal cholesterol levels. Cholesterol is a body part and a long stay in the side chain composition. The total amount of cholesterol in the body accounts for 0.2% of body weight, bone contains about 10 mg, containing about 100 mg of skeletal muscle, visceral and more in the 150 to 250 milligrams, slightly higher content of liver and skin, about 300 mg. Brain and nerve tissue was the highest, per 100 grams of tissue containing about 2 grams, the total amount of the total body about l / 4.

Application of cholesterol
Cholesterol in the body has a wide range of physiological functions, but the overdose would lead to high cholesterol, have a negative impact on the body. Modern studies have found that atherosclerosis, venous thrombosis and gallstones and high cholesterol are closely related. If high cholesterol is a simple dietary modification is the best approach, if accompanied by high blood pressure is the best case in the monitoring of blood pressure as long as medically determined to be high blood pressure, you need to use antihypertensive drugs. Hypercholesterolemia, atherosclerosis is the result of a very important reason, so please attention. Nature of cholesterol mainly in the animal food among the plants without cholesterol, but there are very similar to the structure of the material and cholesterol - plant sterols. Plant sterols induced atherosclerosis without effect. In the mucosa, plant sterols (especially Valley steroids) for competitive inhibition of cholesterol absorption.

The distribution of cholesterol
Although the cholesterol found in animal foods being, but different animals and different parts of animals, the cholesterol content is very inconsistent. In general, the cholesterol content is higher than bushmeat poultry fat than lean meat, shellfish and molluscs than ordinary fish, and egg yolk, fish roe, animal offal is the highest cholesterol levels. Typically, 100 grams of food each less than 100 mg of cholesterol called low-cholesterol food foods such as eel, prostitution, carp, pig meat, bovine meat, sheep meat, duck, etc.; to 100 grams of cholesterol content in food is 100 to 200 mg of food called moderate cholesterol foods, such as grass carp, crucian carp, silver carp, eels, eel, turtle, crab, pork chops, chicken, etc.; and 100 grams of food each cholesterol from 200 to 300 mg of food, said high cholesterol foods, such as kidney, liver, tripe, shellfish meat, termite meat, egg yolk, Crab and so on. Should be minimal in patients with hypercholesterolemia to eat or not eat high-cholesterol food.

About Cholesterol
In the treatment of the role of cholesterol in food, there are two distinct one-sided view. One view is that cholesterol is extremely harmful to not eat. One-sided view that this is due to people who hold this view on the role of cholesterol in the body lack of clear understanding. In fact, cholesterol is a component of cell membranes, involved in a number of steroid hormones and bile acid biosynthesis. Since many other foods containing cholesterol also very rich in nutrients, eat the food if too much can easily lead to nutritional imbalance, leading to anemia and other diseases. Another view is that cholesterol in the human body without much damage, people can enjoy uptake. This view is false, is due to hyperlipidemia, lack of understanding of the pathogenesis of coronary heart disease. Long-term excessive intake of food cholesterol will lead to atherosclerosis and coronary heart disease incidence and development. How much to eat in a day more appropriate to the issue of cholesterol, is generally believed that healthy adults and is not associated with coronary heart disease or other atherosclerotic disease in patients with hypercholesterolemia, a daily intake of cholesterol should be below 300 mg in associated with coronary heart disease or other atherosclerotic disease in patients with hypercholesterolemia, a daily intake of cholesterol should be below 200 mg. The best in the diet containing dietary fiber-rich foods, such as: celery, corn, oats, etc.; tea tea pigment can reduce total blood cholesterol, prevent atherosclerosis and thrombosis, green tea better than black tea; vitamin c and e can reduce blood fat, adjust the lipid metabolism, they are dark or green plants (vegetables, fruits) and high content of beans. Limit high-fat foods: such as organ meats, fresh vegetable oil do not eat animal oil. Blood alcohol may increase high-density lipoprotein, strengthening the role of prevention and treatment of hypercholesterolemia. Daily intake of alcohol consumption to no more than 20 grams of alcohol (wine not exceeding 50 grams) is appropriate, the wine more appropriate, but must strictly limit the intake. Cholesterol and more foods are: egg yolk, animal brain, liver and kidney animals, cuttlefish (squid), crab roe, crab ointment. Crab with crab meat per 100 grams of high cholesterol containing 235 milligrams of cholesterol per 100 grams of 460 mg of cholesterol in the Crab. Higher levels of cholesterol in liver, according to analysis in each 100 grams of liver, containing approximately 368 milligrams of cholesterol.

Eat the reasonable control of cholesterol
Low-density lipoprotein cholesterol (referred to ldl-c), can cause damage to the artery; and high-density lipoprotein cholesterol (referred to hdl-c), is a function of the arteries clean and clear. Here are some experts recommend the diet to reduce body ldl-c levels, and increase the hdl-c content. 1, more fish Ω-3 fatty acids for one (found in tuna, mackerel, salmon and sardines and other fish) on the hdl-c of the impact of the research shows that when the number of fish per week or even daily 1 1 , can effectively reduce the intake of saturated fat. 2, eat more foods rich in fiber Bread, whole grain and high fiber content of foods, can reduce the body ldl-c levels. Nutrition experts point out that in order to achieve the effect of cholesterol, dietary fiber to reach 15 to 30 grams. Canada in the breakfast plate of blackberries, add half a bowl of lentils for lunch, dinner by adding a whole-wheat pasta, plus five pairs of semi-dry cut open the peach as a snack. 3, eat soy products Vegetable protein such as tofu and soy products expanded, the plant contains a natural chemical substances called isoflavones. Research shows that this chemical will help to damage arteries ldl-c purged from the body. 4, adequate intake of vitamin c Tufts University in Massachu_set_ts, conducted the study showed that blood levels of vitamin c body hdl-c and proportional to the content. Experts suggest eating 3 to 4 copies per day of vitamin c rich foods, such as citrus fruits, potatoes, broccoli, cauliflower, strawberries, papaya and dark green leafy vegetables, can increase blood levels of vitamin c to improve the number of body hdl-c, to ensure patency. health world tips: Cholesterol is an essential human nutrient. It is not only the structural component of the body, or the synthesis of many important raw materials. Not eat food containing too much cholesterol, could easily lead to anemia, reduce the body's resistance; but long-term high intake of cholesterol, is not conducive to good health, will increase serum cholesterol levels, increase the risk of cardiovascular disease risk. Therefore, the scientific method to promote adequate intake of dietary cholesterol. Cholesterol and low cholesterol foods are: all plant foods, eggs, egg whites, poultry, dairy, fish, etc.; Cholesterol and more foods are: egg yolk, animal brain, liver and kidney animals, cuttlefish (squid), crab roe, crab ointment. Generally believed that cholesterol intake to less than 300 mg per day is appropriate (the equivalent of one egg yolk with a cholesterol). health world tips: The researchers also found that non-smoking, proper drink some wine and a few times a week exercise to improve heart function is to improve the human body hdl-c number 3 key. l eat less high fatty foods Animal liver, eggs, red meat such as beef and mutton, are higher levels of ldl-c food, eat these foods, do not help reduce the amount of cholesterol in the body.

Function of cholesterol
(1) the formation of bile acid: Bile produced in the liver and stored in the gallbladder, after release into the small intestine to digest fat and being mixed. The function of bile is to large particles of fat into small particles, making it easy and small intestine enzyme. Tail in the small intestine, 85% to 95% of the bile is re-absorbed into the bloodstream, the liver re-absorption of bile acids so as to continuously cycle, the remaining bile (5% -15%) excreted with the feces. Liver bile acid to be produced to make up for this new 5% to 15% loss, then you need cholesterol. (2) constitute the cell membrane: cholesterol constitutes an important component of cell membranes, the membrane surrounding each cell in the body, the cholesterol to its basic components, accounting for more than 20% of the plasma membrane lipids. It has been discovered that the lack of cholesterol fed animals, the results of the red blood cell fragility of these animals, likely to cause cell rupture. The results show that the temperature is high, cholesterol can prevent the disorder in bilayer; the temperature is low but also interfere with the orderly and prevent the formation of liquid crystal to maintain its liquidity. So, imagine if there is no cholesterol, cells can not maintain normal physiological function, life will be terminated. (3) Synthetic hormones: hormones is to coordinate the multi-cellular organism metabolism in different cell chemical messenger involved in the metabolism of the body of various substances, including sugar, protein, fat, water, electrolytes and minerals, metabolism, the maintenance of the human body normal physiological function is very important. Human adrenal cortex and gonads by the release of various hormones such as cortisol, aldosterone, testosterone, estradiol and vitamin D are all steroid hormones, its precursor is cholesterol. `

Another is the primary low-cholesterol, and more from the diet is not balanced, long-term vegetarian, the partial eclipse, caused by low intake of cholesterol. After excluding the possibility of other diseases, to maintain normal blood cholesterol levels, we must develop a balanced diet. Cholesterol low, you can eat more fish, animal offal, eggs and other food. What to eat to lower cholesterol 1. Eat or not eat animal organs, egg yolk and other high cholesterol foods, intake of cholesterol in the diet (less than 300 mg a day). Cholesterol in the blood mainly (70%) synthesized in the liver, only a small part (30%) from food, to reduce cholesterol intake alone does not fundamentally treat high cholesterol, but the control of food intake on cholesterol lower cholesterol is still helpful. According to the standard American Heart Association recommended daily intake of cholesterol should be less than 300 mg or less, and 1 egg yolk cholesterol of 250 to 290 mg; 2 two halogen cook as much as a good liver cholesterol 469 mg. 2. Low fat meat, and Hun, reduce saturated fat intake. Wide range of saturated fat found in meat, eggs, dairy foods, especially fat, saturated fat and visceral Hun content of most. Saturated fat can promote blood low-density lipoprotein cholesterol (LDL-C) students with high role, its effectiveness even more than cholesterol itself. 4. Olive oil, tea oil, corn oil and rapeseed oil contain monounsaturated fatty acids can reduce low-density lipoprotein cholesterol (LDL-C) role. In the daily diet with soybean oil, peanut oil and other vegetable oils with food. 5. Fish oil and lecithin can reduce the role of lipids, but its role is mainly for increased triglycerides, cholesterol-lowering effect is small (of course, still be useful.) 6.

And release of cholesterol from the liver means
Cholesterol is the body's most abundant steroid compounds, both as a cell membrane's composition, but also steroid hormones, bile acids and vitamin D precursors. So for most organizations, to ensure the supply of cholesterol to maintain its metabolic balance is very important. Cholesterol exists in the body tissues, of which about 1 / 4 distribution in the brain and nervous tissue, brain tissue accounted for about 2% of the total weight. Liver, kidney and intestine and other internal organs and skin, adipose tissue also contain more cholesterol per 100g tissue containing about 200 to 500mg, to the liver for up to, and less muscle, adrenal gland, ovary and other organizations can be up to 1% cholesterol -5%, but the total rare. Source of human steroid synthesis by the body and from food intake, normal daily diet contains about cholesterol, 300-500mg, mainly from animal organs, egg yolk, butter and meat. Plant foods contain cholesterol, and contain plant sterols such as β Valley sterol, ergosterol, etc., they are not easily absorbed by the body, excessive intake can inhibit the absorption of cholesterol.
