Nowadays, more and more people suffer from "acrophobia" and regard high cholesterol as a scourge. Whenever high cholesterol is mentioned, it is considered to be a synonym for coronary heart disease, cerebrovascular disease, and arteriosclerosis. "low". However, recent studies from abroad show that people with low cholesterol are susceptible to aging and are prone to diseases such as cancer and depression. So what is cholesterol? What role does it play in the human body? Is cholesterol high or low? At what level does it maintain its health benefits? Liang Youfu, a nutritionist at the People's Liberation Army 302 Hospital, suggested that the daily intake of cholesterol is not more than 300 milligrams per person, which is equivalent to the amount of one egg. People do not live without cholesterol
Dr. Leung said that each person's normal growth and development requires three major nutrients, namely, protein, fat and carbohydrates. Among them, lipids mainly include triglycerides, phospholipids and sterols. Cholesterol is a class of sterols. The most important steroid. It is an important component of the cell membrane and plays an important role in maintaining normal cell functions. Cholesterol is an indispensable raw material for maintaining the body's normal metabolism. It is an important material for anti-ageing and prolonged life, and it is also an important raw material for various hormones in the body, such as steroids. Hormone, vitamin D, an important raw material for bile acids. It can be said that cells can not do without cholesterol, the body can not be separated from cholesterol, the body once there is no cholesterol, not only about health and longevity, even the human body's normal physiological metabolism and life processes can not continue. Cholesterol is good or bad
According to Dr. Leung, cholesterol is mainly found in animal foods, especially animal viscera and brain, but low in fish and milk, such as every 100 grams of porcine brain, sheep brain, egg yolk and eggs. (including egg white) contains 2571 mg cholesterol, 2004 mg, 2850 mg and 585 mg, respectively. There are two main sources of cholesterol in the human body: one is endogenous, which is synthesized by the liver, which accounts for about 70% of the total cholesterol; the other is exogenous, that is, cholesterol from food. About 30%. If the long-term intake of cholesterol in food is insufficient, the body will intensify synthesis to meet the needs of the human body.
Cholesterol is divided into high-density cholesterol and low-density cholesterol, the former has a protective effect on cardiovascular, usually called "good cholesterol", the latter is high, the risk of coronary heart disease will increase, usually called " Bad cholesterol." Cholesterol levels in the blood range from 140 to 199 mg, which is a relatively normal cholesterol level. The more fat, the higher the cholesterol absorption.
Dr. Leung said that cholesterol in foods is not completely absorbed by the body, and the absorption of cholesterol is mainly dependent on the following factors:
First, when the bile acids in the body are lacking, the absorption of cholesterol will be significantly reduced. The fat in the food can promote the secretion of bile. The decomposition product of fat is also beneficial to the absorption of cholesterol. Therefore, the more fat in the food, the more it can increase. Absorption of cholesterol.
Second, the absorption rate of cholesterol in the body decreases with the increase of cholesterol in food. The higher the content of cholesterol in food, the lower the absorption rate of the human body, but when the content of cholesterol in food is high, the body's absolute absorption will increase.
Third, saturated fatty acids help increase cholesterol, and unsaturated fatty acids help lower cholesterol.
Fourth, certain components of food affect the absorption of cholesterol, such as gluten can reduce the absorption of cholesterol, dietary fiber in food also has such a function. High or low cholesterol can damage health
It is well known that high levels of cholesterol in human blood can cause atherosclerosis, which is a major risk factor for coronary heart disease, myocardial infarction and stroke. However, if the cholesterol in the blood is too low, it will cause damage to the body.
Cholesterol is an essential “building material†for the body to support the structure of all cells in the body. Cholesterol-deficient cells are like a box of jellies with small holes. When contacted with brain-regulating chemical molecules, poorly dense cells cannot respond properly. The working mechanism of a cell is similar to a lock and a key, a cell is a lock, and a neurotransmission is a key. If the cell structure is not good, the key may be difficult to unlock and the cells cannot be activated. As a result, human emotions are extremely unstable.
In addition, when the body lacks cholesterol, the cell membrane tissue will be destroyed, and the function and activity of the leukocyte of metamorphosis cells will be weakened. It will not be able to effectively identify, kill and phagocytose mutant cells including cancer cells, and the human body will suffer from diseases such as cancer. . Data show that people with low cholesterol in the body have a 3 times higher chance of developing colon cancer than normal cholesterol, and the prevalence of other cancers is also greatly increased. It is advisable to consume 300 mg cholesterol per day.
Human cholesterol is not dispensable but it must be maintained at a certain level so that the physiological process can proceed smoothly. So how much is the daily intake of the human body? Dr Leung recommends that daily cholesterol intake should not exceed 300 mg, which is equivalent to the amount of one egg. Elderly people should eat 100-150 grams of meat every day, 1-2 eggs, equivalent to about 200-300 mg of cholesterol. At the same time, Dr Leung reminded people to use scientific diets in their daily diet and pay attention to:
First, try to use low-cholesterol foods, such as various plant foods, as well as poultry meat, dairy products, fish, egg whites, etc.;
Second, avoid high-fat, high-cholesterol foods, especially foods rich in saturated fats, such as lard and various animal oils, brains, roe, crab yellow, etc.;
Third, eating more foods rich in dietary fiber and phytosterols, such as various green vegetables can help lower cholesterol.
When appropriate intake of animal foods rich in cholesterol, can increase the intake of calcium phosphate-rich soy products, mushrooms, etc., in order to reduce the deposition of cholesterol in the blood vessel wall and maintain blood vessel function.
