Hello! I have been a doctor for 21 years. My name is Georgy Olegovich Sapego. This article will have questions and answers about cholesterol.
Question: And what causes low-density lipoproteins to be deposited in blood vessels? They are not postponed for everyone. What makes vessels "rough" or "perforated"?
Answer: This is not a mechanical process. Cholesterol is not deposited. He is dragged in by immune cells. If something is wrong in the wall of the vessel, then the cells are pulled up there and bring cholesterol with them. Out of order - this is not a crack or a hole, but on the contrary a thickening of the wall. Sometimes thickening occurs in places where the blood swirls, and sometimes for no apparent reason.
Question: That is, the immune cells do their job (necessary?), Bring cholesterol, and the whole huge army of doctors is doing everything to prevent this cholesterol from getting there? And they don't know why there is a disorder with the vessel wall?
Answer: Immune cells are weird left and right. Sometimes they destroy the heart valves, sometimes they store cholesterol. Because they will drag cholesterol into the vascular wall, no one will benefit. Theories are different, but it doesn't make it easier for us. The history of dealing with a heart attack or stroke is based on statistics. If, with certain test results, you are treated in a certain way, then the probability of dying is lower. If not treated, then the likelihood of dying is higher. Personally, I don't care about theory. Today there will be one theory, tomorrow - another. The main thing is that fewer people die.
Question: Why do young men have heart attacks? Also cholesterol in the vessels?
Answer: Hereditary cholesterol, gluttony with smoking, smoking with the use of any prohibited. Usually, one of these combinations can lead a man to a heart attack at the age of 30.
Question: What is the harm of palm oil?
Answer: Palm oil is less harmful in composition than cocoa butter or coconut butter. And if the manufacturer shit in butter, then it is the manufacturer's fault, not the oil palm.
Question: Can you clarify how quickly atherosclerosis develops with high cholesterol? Month? Year? Five years? And how can it manifest itself before a heart attack?
Answer: Atherosclerosis begins to form in childhood. From high cholesterol and high blood pressure, it develops faster. It manifests itself in different ways. Where the blood flow is blocked, it will manifest itself there. Sometimes angina pectoris, sometimes pain in the legs, sometimes the head works worse. Older people start looking for problems.
Question: So this is a lottery? And the problem is more about immunity than high cholesterol?
Answer: The problem is high cholesterol. Hereditary syndromes are rare. Usually the problem is binge eating fatty. Immunity only prepares the ground. The rudiments and sprouts of atherosclerosis appear there. Then everything goes bad due to high blood pressure and high cholesterol levels. Both that, and another dramatically stimulates these... sprouts or rudiments of atherosclerosis. This is not a lottery, but a risk. It can be calculated. That is, it is quite predictable. There are prevention methods for each level of risk. This is what a cardiologist does. There are exceptions when people with high cholesterol live up to 100 years old, but it's better not to think about them, because people predictably die in batches as early as 60 years old.
Question: But what about the fact that only 20 percent of the maximum cholesterol is produced from food?
Answer: About 20% is a popular glutton bike. Cholesterol in our body can be found in any cell, and the liver makes it from anything. Only when a person has a high risk of heart attack, then cholesterol in food is limited to 300 mg / day. This affects survival.
Question: If the liver makes cholesterol from anything, then why does limiting cholesterol in food affect survival?
Answer: Because now there is a developed industry of feeding saturated fat and trans fat to consumers. Worst of all are the spenders. Saturated fat isn't much better. They all raise the level of "bad cholesterol". Cholesterol in experiments killed only diabetic patients. And also contributed to the development of heart failure. Heart attacks or strokes from him did not noticeably more, so the Americans removed the indication of 300 mg per day from their recommendations. The idea was picked up and began to eat eggs. European cardiologists did not remove these restrictions and left the 300 mg limit (Europeans are no worse than Americans). Nutritionists say that those who eat a lot of cholesterol along with it eat a lot of saturated fat and trans fats and therefore die. At the same time, American nutritionists say eggs are CHEAP and healthy food. But how many of them you can eat, no one says for sure. Every publication reiterates that eggs are CHEAP and will help the poor to be strong (almost literally they say so). In fact: those who eat a lot of cholesterol for some reason get a heart attack, although cholesterol itself in the experiment is not entirely clear.
Question: How do you feel about the theory of Dr. Atkins? He writes in his books that "food cholesterol is harmless."
Answer: As a theory, and I feel. It is possible and even necessary to eat fats. Only saturated fat should be less than 7%, cholesterol less than 300 mg per day, and as little trans fats as possible. Official expert recommendations are written in blood. And they need to be believed.
QuestionWho can be convinced by simple denial without proof?
Answer: The evidence is statistics on deaths from heart attacks or strokes. Experts analyze statistics and offer recommendations. There will always be people who follow the recommendations and people who don't follow the recommendations. This is natural selection.
