This is how an egg changes the composition of your blood, does it look the same as you think?

[Professional doctors tell you about health every day]

Eggs are a popular food that people love, and an egg for breakfast every day has become a standard for many people. However, many people have concerns about eating eggs, especially those with high blood lipids and those with diabetes, hypertension, and cardiovascular and cerebrovascular diseases. Since one of the treatments is to control blood lipids, they are always worried about eating high cholesterol. Is it justified to worry that the eggs will increase blood lipids and aggravate the disease? Let's take a look at what kind of changes eating an egg has on the blood composition, and it will be clear.

Before talking about this question, let's first understand two small knowledge of human nutrition:

First, there are two main sources of various nutrients that the human body needs. One is to ingest it from the daily diet, which is the most important way; the other is to synthesize itself. For example, there are about 20 kinds of amino acids in the human body that participate in physiological activities, of which eight are not synthesized by the human body and must be ingested through food, which are called essential amino acids. Therefore, food rich in high-quality protein must be included in the daily food to meet the needs. ; Another example is the often said cholesterol, in fact, 80% is synthesized by the body itself, and the remaining 20% ​​needs to be supplemented through food every day.

Second, the various nutrients that the human body needs are interrelated and mutually restrictive. For example, the dynamic balance between sodium and potassium can maintain the stability of blood pressure; another example is various vitamins A, B, C, D, E, etc. , When the body absorbs from food, a certain proportion of various vitamins can be absorbed to the maximum, that is to say, it is absorbed as a whole, but the absorption rate cannot be maximized when one of them is supplemented. And so on, a reasonable diet is very particular about the comprehensive and appropriate proportion of various nutrients in food.

After understanding this knowledge, let's look at eggs. Eggs are the egg cells that breed life in nature. The initial life depends on it to complete the growth and development, so the nutrients it contains are very comprehensive and in the right proportion. Nutritional studies have found that the nutrients contained in eggs are very close to the nutrients needed by the human body. More than 98% of the most important high-quality protein will be absorbed by the human body. Although the content of fats such as cholesterol is high, these cholesterols are different from other foods. The cholesterol in the body is more beneficial to the human body to prevent and treat diseases, specifically:

An egg contains about 6.25 grams of high-quality protein, and adults need an average of 1 gram of high-quality protein per kilogram of body weight per day. If the protein provided by an egg alone is far from enough, However, the protein contained in eggs is the essential protein that the human body needs, especially the methionine that many other foods do not contain are very rich in eggs and can be completely absorbed by the human body, so a small egg provides high-quality protein. But very important.

The fat contained in an egg contains about 250mg of cholesterol, and the human body needs to be supplemented with 300mg of cholesterol from food every day, so eating an egg will not affect the total cholesterol. Some friends may say that after eating eggs, if other foods, such as meat, also contain cholesterol, should you not eat them, or else the cholesterol will definitely be excessive?

This kind of worry is completely unnecessary, because the human body does not completely absorb the cholesterol in food, and the absorption rate is only about 30%, that is to say, only about 75mg of cholesterol in an egg is absorbed into the blood. Food doesn't make a big difference.

If converted into the indicators of blood lipid test, eating an egg will increase total cholesterol by 0.07mmol/L, and the elevated cholesterol also contains high-density lipoprotein that is beneficial to the human body, which is beneficial to high blood lipids, diabetes, hypertension and For people with cardiovascular and cerebrovascular diseases, increasing the level of high-density lipoprotein in the body is also a goal of treatment. In the absence of effective drugs to increase the level of high-density lipoprotein, an egg a day is beneficial and necessary.

In addition, an egg contains phosphorus, zinc, iron, vitamin D, vitamin E, vitamin A, vitamin B, vitamin B2, vitamin B6, riboflavin, niacin, etc., all of which the human body must consume every day. Therefore, except for people with hereditary familial hypercholesterolemia, who should not eat eggs due to the need to strictly limit the intake of cholesterol, there is no need for other people to worry that an egg a day will lead to increased blood lipids.

It should be reminded that: the best way to eat eggs is to cook them, avoid frying and frying to increase the amount of fat and destroy nutrients. There is also a trick to boiling eggs, that is, put the eggs in after the water is boiled, and use the principle that the protein in the egg white will shrink when heated, which can not only ensure that the eggs will not be boiled, but also help to separate from the egg shell. Well peeled.
