Eggs, known as "whole nutrition food", an egg is rich in protein, amino acids, lecithin and minerals, etc., can meet the vast majority of our body's requirements for nutrition. However, because the yolk contains more cholesterol, eggs have also been controversial, and some people even said that eating eggs will increase the possibility of cardiovascular disease.
As soon as these remarks came out, many people resolutely gave up the yolk, or even the whole egg.
Can eggs be eaten? What is the relationship with cardiovascular disease?
Recently, the Research Team of Peking University conducted a study on the relationship between eggs and cardiovascular disease, the population involved in this study is from the mainland population, the research conclusions may be more in line with the Chinese group, let's take a look at it.
1. Peking University: 4-7 eggs per week, heart health is guaranteed
On May 24, the journal eLife published a study conducted by the team of Yu Canqing, an associate professor at Peking University, showing that eating 4-7 eggs a week can help protect heart health and reduce the risk of heart disease.
The study included 4778 people, of which 3401 people had cardiovascular diseases, volunteers aged 30-79 years old, through questionnaires, to understand the diet and egg intake status of volunteers in the past 1 year, and finally found that people who ate 4-7 eggs per week had APOA1 in their blood, a beneficial protein, and HDL-C, which is what we call good cholesterol levels, while LDL-C, that is, bad cholesterol levels are low, and the probability of heart disease and stroke is low.
It can be seen that eating eggs in moderation does not increase the risk of cardiovascular disease, but helps prevent cardiovascular disease.
Second, one egg every morning, the body can still get these 4 benefits
The Peking University study tells us that eating eggs in moderation is good for the health of cardiovascular disease, and in addition, eating an egg every morning can also get these 4 benefits for the body.
1. Supplement protein
Eggs belong to high-protein foods, in which the protein content is as high as 13g/100g, and protein is the material basis of all life, ensuring sufficient protein is of great significance to human health, and the amino acid composition of protein in eggs is better, basically similar to the human body, and the absorption and utilization rate is also high, so if you want to supplement protein, eating eggs is a good choice.
2. Increase satiety
Due to the high protein content in eggs, protein can stimulate the secretion of a gastrointestinal hormone called PPY, which can inhibit appetite and increase postprandial satiety, which can help lose weight.
3. Improve memory
Eggs contain a large number of lecithin, choline and other nutrients, of which choline is an indispensable substance for the synthesis of brain neurotransmitter - acetylcholine, which can activate the brain nerve conduction function, improve the speed of information transmission, and enhance the brain's memory ability; In addition, the lecithin component can also promote the development of brain cells, thereby improving memory.
4. Protect vision
Egg yolk contains two major antioxidant substances, lutein and zeaxanthin, which are essential nutrients for the eyes and protect the photoreceptor cells in our retina from sunlight and oxidation.
It can be seen that eggs are a high-quality ingredient, and proper consumption can benefit the body a lot, and everyone can eat more.
Third, cancer patients can not eat eggs, otherwise it will recur?
There is a widespread rumor about the consumption of eggs, saying that "eggs are hair objects, cancer patients can not eat", so is this statement reliable?
In fact, cancer is a chronic wasting disease, which is different from inflammatory and allergic diseases, and there is no necessary connection with "hair".
On the contrary, cancer cells often consume and rob a large number of nutrients in the human body during the growth and proliferation process, so it is more necessary to pay attention to nutritional supplementation than ordinary people, otherwise patients may affect the effect of anti-cancer due to lack of sufficient nutrition as the basis for disease resistance.
The egg is rich in protein, amino acids, minerals and vitamins and other nutrients, and the proportion is closer to the needs of the human body, and it is easier to be absorbed and utilized after ingestion, so for cancer patients, it is a way to supplement nutrition. Especially after surgery, radiotherapy and chemotherapy, the patient's body is more weak, at this time to eat some eggs, but help to enhance the physique and anti-cancer ability!
In short, cancer patients can eat eggs, but some are allergic to eggs, or suffer from severe liver and kidney function damage, biliary obstruction, uremia and other diseases that need to follow the doctor's advice, which is another matter.
Fourth, do not let the eggs become "poisonous eggs", these 3 kinds of eggs eat less
Eggs are good things, but some eggs may be "poisonous eggs" that should be avoided.
● Loose yolk eggs
Loose yolk eggs are mostly found in the transportation process, and the oscillation is more severe, which may lead to the rupture of the yolk membrane, and eventually there will be mechanical loose yellow; In addition, if it is placed for too long, it may also be invaded by pathogens such as bacteria from the pores of the eggshell, thereby destroying the protein structure and causing yellowing. If loose yolk eggs are found, and the protein has become denatured and has a foul smell, it should be disposed of in time.
● Sticky shell eggs
Most of the sticky shell eggs are left for too long, resulting in poor toughness of the yolk film, which will make the yolk stick to the eggshell. If a sticky shell egg is found, it is necessary to pay attention to the color at this time, if the local color is red, it can also be eaten after high temperature treatment such as decoction; However, if the part is dark black and has an odor, it is best to throw it away.
● Stillborn eggs
Stillborn eggs mainly refer to eggs in the process of hatching, due to temperature, humidity and bacterial pollution and other reasons to cause embryos to stop developing eggs, the nutrition in which has basically been lost, if the world of death is relatively long, protein will be decomposed will produce a variety of toxic substances, after eating can bring a variety of hidden dangers to health, so it is not recommended to eat.
Proper intake of eggs has a variety of health benefits, cancer patients unless they need to follow the doctor's advice for other reasons, they can also eat, but when eating eggs, pay attention to avoid "poisonous eggs" so as not to endanger health.
