According to data released by the World Health Organization , cardiovascular diseases, infectious diseases and cancer are currently the three main causes of human death. Among them, the number of people who die from cardiovascular disease is the largest, accounting for 29% of the total global deaths. %!

The relationship between diet and cardiovascular disease has always been a focus of everyone's attention. Among them, eggs are the focus of different opinions - some people think that the high cholesterol of eggs will increase the risk of cardiovascular disease, so they dare not eat them; but In recent years, many studies have shown that egg intake has nothing to do with dyslipidemia and in healthy people, and those with a history of cardiovascular disease can consume it in moderation.

So should we eat it or not?

Research has confirmed that egg intake

can improve blood lipids levels and reduce cardiovascular disease

Eggs contain almost all the nutrients needed by the human body and are known as the "ideal nutrient bank". They are beneficial in promoting growth and development and strengthening the brain. It has benefits in improving intelligence, protecting eyesight, and assisting in delaying aging.

In 2018, Peking University School of Public Health Professor Li Liming's research team published research results in the BMJ journal "Heart": one egg a day is associated with an 18% reduction in the risk of death from cardiovascular disease and a 28% reduction in the risk of death from hemorrhagic stroke. .

Why are ordinary eggs so useful?

Recently, researchers from the Department of Epidemiology and Health Statistics of Peking University used targeted nuclear magnetic resonance technology to detect 225 metabolites in plasma samples of more than 4,000 participants and discovered the mechanism - moderate egg intake. , may be able to reduce the risk of cardiovascular disease by increasing the amount of heart-healthy metabolites in the blood!

The specific performance is:

1. Eggs can increase good cholesterol ,

lower blood cholesterol

Egg intake is positively correlated with the concentration of high-density lipoprotein (good cholesterol). The increase in the levels of these high-density lipoprotein helps clear cholesterol in blood vessels and improves cholesterol metabolism properties, thus having a protective effect on cardiovascular disease.

2. Eggs can promote the liver

metabolism of bad cholesterol.

Egg intake is positively correlated with the apolipoprotein A1 index. Apolipoprotein A1 can transport peripheral cholesterol to the liver for metabolism, thereby helping to reduce the level of bad cholesterol.

In summary, egg intake changes the expression of metabolic markers, and these altered markers are inversely related to the risk of cardiovascular disease. Therefore, it can be speculated that egg intake can change the body's metabolism, thereby reducing the risk of cardiovascular disease. risk.

Eat eggs healthily, but you also need to know these points.

1. There are certain intake requirements.

Eggs are beneficial, but the more you eat, the better. A recent study conducted by Fuwai Hospital of the Chinese Academy of Medical Sciences showed: Eat it every week. 3 to 6 eggs are more beneficial to health. The

study included 60,952 adults. The results showed that subjects who ate 3 to 6 eggs per week had lower total cholesterol, triglycerides , low-density lipoprotein cholesterol , and high-density lipoprotein cholesterol. (good cholesterol) is elevated and the risk of cardiovascular disease is also low.

2. Don’t throw away egg yolks

Many people know that the cholesterol content in egg yolks is high, so they only eat egg whites. Actually not recommended.

Because the yolk is like the core of an egg, it contains a variety of vitamins and minerals - including all B vitamins , vitamin A, vitamin D, vitamin E, vitamin K and trace amounts of vitamin C; calcium, phosphorus , iron, zinc, selenium and other minerals are relatively rich.

Therefore, except for special groups such as hyperlipidemia, it is recommended to eat whole eggs.

3. Don’t worry about choosing eggs.

The first step in eating eggs is to "select", but white-preserved eggs, brown eggs, black eggs, free-range eggs... There are many types of eggs on the market, and the prices vary greatly. So their nutrition What’s the difference in ingredients?

Some experts have conducted relevant experiments and found that the ingredients in various eggs are similar, and the nutrient content has not increased due to the increase in price.

So when buying eggs, just choose fresh ones ~
