Neighbor Uncle Wang will go to the supermarket every week to buy eggs, and always introduce to the neighbors on weekdays, this egg looks ordinary, but it is actually very deeply learned. Eggs are actually "healthy eggs", eat one a day, not only improve nutrition, but also prolong life. However, his wife did not approve, thinking that eating eggs would increase cholesterol, which was not conducive to cardiovascular and cerebrovascular health. The two were always deadlocked over eating eggs every day.
When it comes to eggs, almost everyone has eaten them. Eating an egg at breakfast is standard for many people. As a common food in daily life, eggs are rich in protein and can supplement the nutrients that the human body lacks, which is beyond doubt.
However, with the increasing awareness of people's health care today, many people feel that the protein and fat and other components in the egg cannot be decomposed and digested in time after ingestion, thus accumulating in the blood vessel wall, which is not conducive to the health of the blood vessels. Even the medical community in some developed countries list eggs as "contraindicated".
So is eating an egg a day a health regimen or damaging cardiovascular and cerebrovascular diseases? Today, the doctor will explain it all to you through this article.
Does eating 1 egg a day have any effect on cardiovascular health?
Most people know that eggs contain a variety of essential amino acids that can supplement the body with effective protein. It can be said to be an ideal natural "tonic". However, in recent years, more and more people regard eggs as the "culprit" of diseases such as hypertension, atherosclerosis, and coronary heart disease.
They believe that eggs contain high cholesterol, if you eat an egg every day will make the body's cholesterol exceed the standard, long-term will induce cardiovascular and cerebrovascular diseases. For people who have this disease themselves, it is simply "adding fuel to the fire", so many people are far away from eggs. Many people call eggs "harmful eggs", but is this really the case?
In fact, this statement is one-sided. Eggs do contain cholesterol, but generally do not cause a significant increase in cholesterol in the human body. Conversely, the University of California, Berkeley, has reported in a newsletter that eating one egg a day for most people doesn't raise blood cholesterol levels and may even benefit your heart in some ways.
This is because the lecithin contained in eggs binds to proteins to form a large amount of "good cholesterol" – hdL, which has a vascular clearing effect and can remove cholesterol from the walls of blood vessels. And the unsaturated fatty acids in eggs can also further reduce cholesterol.
Harvard University in the United States has done a study in this regard, sampling nearly 210,000 people, let them eat 1 to 3 eggs a day. The results show that this not only does not bring damage to the body, but reduces the prevalence of cardiovascular and cerebrovascular diseases and protects the health of cardiovascular and cerebrovascular diseases.
Therefore, many people think that eggs contain higher cholesterol, and the theory that eating them will increase blood lipids has been completely overturned. Eating 1 egg a day is not only harmless to the body, but may have a special protective effect on the cardiovascular system.
Even people with high blood pressure, hyperlipidemia, and diabetes, as long as they control the values of blood pressure, blood lipids and blood sugar on a daily basis, and consume an appropriate amount of 1 egg per day, it will not damage their own vascular health. It has a certain auxiliary effect on the prevention of cardiovascular and cerebrovascular diseases.
In addition, eating one egg a day can also bring other benefits to the body.

Therefore, from the perspective of nutrition, in order to ensure a balanced diet, meet the needs of the body, and will not be overnutrient, under normal circumstances, the elderly eat 1 egg a day, and young and middle-aged people eat 2 eggs a day.
But some children are very picky about eating eggs, and some only love egg whites and don't like to eat egg yolks. Some friends think that egg whites are more nutritious than egg yolks, so they choose to eat only egg yolks instead of egg whites, so which of the egg whites and egg yolks is more nutritious?
Egg yolks and egg whites, which is more nutritious? Here comes the truth
For egg yolks and egg whites, many people feel that egg yolks are more nutritious. Here, we can first analyze what ingredients they contain.
Both contain the best proteins. But egg yolks contain a lot of vitamin A, vitamin B, vitamin C and vitamin E, etc., and also contain a lot of lecithin. The egg white mainly contains protein, and also contains a small amount of acetic acid. Protein lubricates the skin, and acetic acid protects the skin from bacterial infections. Moreover, egg whites also have the effect of clearing heat, detoxifying, beauty and anti-aging.
If you make a comparison, egg yolks are the core of eggs, and the nutrients in them may be a little richer than egg whites. Compared with egg yolks, the nutrient content of egg whites will be much lower. Friends who are familiar with hatching chicks may know that the nutrients of the egg whites are transported into the egg whites during the incubation process. In fact, this is the truth.
But it is not that the egg white is bad, so the doctor recommends that when eating eggs every day, both are the best choice, because the yolk and egg white have their own nutrients, there is no conflict in eating, both eat egg white and egg yolk, which is conducive to the full absorption of nutrients, more conducive to good health.
However, for some people with allergies, it is necessary to reduce the intake of egg whites every day to avoid inducing allergies.
There is also the fact that in the way of eating eggs, it is best to eat boiled eggs, so that the digestibility of the human body will reach higher. In addition to restoring the taste of the food itself and enjoying the delicious taste of eggs, it can also avoid related food hygiene problems and eat safely and healthily. Uncooked eggs can not be eaten, boiled eggs with cold water soaked in avoid storage, which will reduce the nutrition of eggs.
Therefore, in the way eggs are cooked, boiled eggs are the best choice. However, there are many people of the older generation who think that "boiling water for eggs" has a higher nutritional value, is this the truth? Let's look down.
Can the "boiling water washed eggs" that the older generation often eat can be eaten for a long time?
The so-called boiling water to wash eggs is to directly mix boiling water with broken raw eggs and drink them. Many people of the older generation believe that this is a "good medicine" that can clear the fire, and when there is fire in the body, it can achieve a good fire removal effect in this way.
In fact, drinking boiled water every day to flush eggs is not much different from boiled eggs in the supplement of nutrients, which are all protein supplements and provides energy for the body. Other than that, there are no other special benefits. There is no scientific basis to prove that it is a good medicine for clearing fire.
On the contrary, this will reduce the absorption rate of nutrients in eggs, and there may be certain potential risks. Long-term drinking boiled water to wash eggs may lead to bacterial infection, food poisoning, acute gastroenteritis or some parasitic infections. Even if it is washed with boiling water at 100 degrees, it will reduce a certain temperature, and it is impossible to ensure that the eggs are boiled sufficiently.
Therefore, it is relatively safer to eat boiled eggs. Whether from a safety point of view, or from a nutritional point of view, it is not recommended to use boiled water to wash eggs to eat, so as not to be detrimental to health.
Final summary
Eggs, as a total nutritious food, should not be discarded. Eating 1 egg a day will not be harmful to cardiovascular and cerebrovascular diseases, on the contrary, it is of great benefit to the body. However, it is best to choose to eat boiled eggs, so that the nutrition will be more comprehensive.
