There is no upper limit for eating eggs in Lai Gourmet Class! New knowledge of cholesterol that must be known.

Lai's misunderstanding of blood vessel obstruction and cholesterol is still haggling over how many eggs to eat a day or stay away from seafood? A few days ago, the National Diet Group of the United States proposed to announce that it would advise the United States to publicize that cholesterol eaten is not equal to blood lipids, and cholesterol in the diet will not be harmful to health.

This is undoubtedly a big flip. 20 10 the national dietary advice group of the United States suggested that the United States * * educate people that the cholesterol intake per person per day should not exceed 300mg, that is, the cholesterol content of one egg should not exceed. This suggestion makes many people turn pale when they smell cholesterol in food, which makes many people afraid to eat eggs or deliberately dig out the yolk when eating eggs.

Why is there such a flip? Because the latest research found that cholesterol in food does not directly enter the blood.

But why on earth was there such a big misunderstanding about cholesterol in the past? Let's talk about how cholesterol is produced in the human body.

Cholesterol is synthesized by the liver in order to repair damaged tissues and various wounds on the body and send it to the injured place through blood. Cholesterol is an oil, oil and water are immiscible, so it can't walk directly in the blood, so it is wrapped in a car, the outer skin can be dissolved in water, and the inner wall can be coated with oil. So that the blood can send them to the place where they need to be repaired.

This kind of cholesterol synthesized by the liver and sent to repair wounds is called low density lipoprotein (LDL), commonly known as "bad cholesterol". On the contrary, the cholesterol recovered from the liver is called high density lipoprotein (HDL).

Why is cholesterol bad? Because patients with cardiovascular obstruction will open the blocked place and find LDL accumulating there, they think LDL is the murderer of obstruction. Therefore, the public began to panic about cholesterol in the diet.

In fact, cholesterol in food is ingested in the digestive system, not in the blood. What needs to be discussed is that cholesterol is the raw material for liver synthesis to repair wounds. Why does it accumulate in blood vessels? There is no knife in the blood vessel, why is there a wound on the inner wall of the blood vessel?

The answer is that when our diet is unbalanced, we eat too much starch or sugar, and blood sugar rises very quickly. When blood sugar metabolizes, it produces a large amount of carbon dioxide, which instantly dissolves in the blood, producing a large amount of acidity, which will corrode protein. If a person's long-term unbalanced diet repeatedly causes blood sugar shock, blood vessels will be eroded again and again and eventually get injured. They will call the liver to synthesize cholesterol to repair it, so as to avoid the risk of blood vessels becoming too thin due to erosion, and once the blood vessels break, there will be a lot of bleeding.

How to avoid blood vessel blockage? The key is to balance the diet and avoid blood sugar fluctuations, not the cholesterol in the food. This wrong research has caused people to misunderstand the concept of long-term diet. Many years ago, I predicted that this mistake was "the biggest joke of this century." The medical profession has actually been waiting for this amendment for 20 years. I also hope that with this amendment, we can stop throwing away nutritious things like egg yolk and be afraid of eating foods containing cholesterol. (Editorial department arranges excerpts)
