Many people believe that heating always destroys nutrients, so eggs are "deprived of nutrients" when they are boiled old。This is a misconception. The main nutrients that eggs provide us with are protein, in addition to being relatively rich in minerals and some vitamins.
1.Heating does not destroy the protein, but helps it to digest and absorb it. 2.
The minerals in eggs are not affected by heating. 3.Vitamin content of raw and hard-boiled eggsThe losses are not huge.
In short, "fully cooked" is good for protein digestion, and "soft-hearted" is good for vitamins, but the nutritional difference between the two is not too big to be entangled.
In terms of security,Hard-boiled eggs predominateEggs are a food that is more susceptible to bacterial contamination. SalmonellaThe pathogenic bacteria that may appear in eggs are very afraid of heat. The U.S. Department of Agriculture recommends that egg products heated above 71 can adequately kill disease-causing bacteria.
The egg white coagulates at around 62, and the yolk starts to set at 68. The whites of the soft-boiled eggs have coagulated, but the yolks have not, indicating that the temperature for killing Salmonella has not been reached. If you happen to encounter contaminated eggs, you will have to ask for more blessings.
The yolk of the fully cooked egg is completely solidified, indicating that the center of the egg has also reached the temperature of killing bacteria, and the safety is guaranteed. The dietitian teaches you to boil eggs "cooked but not old", if you like fully cooked eggs, there is naturally no problem; If you like soft-boiled eggs, you need to balance deliciousness and safety. If the production of eggs is well managed, and there is no bacterial infection in the eggs themselves, then soft-boiled eggs are still safe.
Cooking with sufficient heat is another line of defense for food safety. Comparatively speaking, eggs purchased from large supermarket chains and industrially farmed on a large scale are less likely to have bacterial infectionsIt is also relatively safe to eat soft-boiled eggs.
And the native eggs, stupid eggs, and grass eggs that are sought after by many people are much more uncertain, and the risk of not being fully cooked is even greater. In fact, there are many intermediate states between "soft-boiled eggs" and "hard-boiled eggs". We can also completely manipulate the heat so that the yolk sets just right, but without overheating.
Experts point out that eggs are high-protein foods, and if you eat too much, it can lead to an increase in metabolites and also increase the burden on the kidneys. In addition, the fat rich in eggs is saturated fatty acids, and excessive intake will inevitably cause a sharp rise in serum cholesterol, which can promote cardiovascular disease.
In general, healthy adults should eat 1 egg a day as long as they pay close attention to and control the amount of cholesterol they consume through other sources such as meat and dairy productsAnd try not to eat egg yolks, because one egg yolk contains two-thirds of the amount of cholesterol that a healthy adult should consume each day.

Eggs contain proteins, fats, calcium, and cholesterol, etc., if you eat too many eggs, the cholesterol content will be too high, and too high cholesterol content will cause atherosclerosis and cardiovascular and cerebrovascular diseases.
In addition, if a large amount of protein is eaten, if the protein cannot be digested, it will stay in the intestines, and some bacteria in the intestines will decay and produce toxic substances. After protein is broken down in the body, it will not only increase the workload of the kidneys, but also cause a large amount of water loss in the body, so drink more water to prevent dehydration.
In order to ensure a balanced diet, meet the needs of the body, and avoid overnutrition, under normal circumstances, it is more appropriate to eat one egg a day. Eating too much can have a detrimental effect on our health. It is worth noting:
Do not eat raw eggs, which contain more bacteria.

Everyone knows that eating too many eggs will increase cholesterol, which will then harm health, but in fact, most of the cholesterol in the human body is synthesized by itself, and the liver synthesizes about 1000 mg of cholesterol per day, which is far greater than the cholesterol contained in an egg yolk.
So for normal people, eating one or two eggs a day will not be a problem. However, if you have problems with liver and kidney function, you should consult your doctor's advice before eating eggs to avoid excessive protein in eggs that cannot be metabolized by the liver and kidneys.
Although for eggs can you eat every day? We already have the answer, but in fact, we still have a big misunderstanding about eating eggs.
Myth 1: Eat raw eggs.
Japanese people like to eat raw eggs, but as everyone knows, eating raw eggs is likely to eat the bacteria contained in eggs, such as E. coli, into the stomach, causing gastrointestinal discomfort and even causing diarrhea. The egg whites in eggs are heated and destroyed at high temperatures, making them easier for the body to absorb.
Myth 2: Eat eggs on an empty stomach.
Most people like to eat an egg at breakfast to replenish their energy needs for the day. It's not that it's bad to eat eggs on an empty stomach, but if you eat too much soy milk, meat and other foods with high protein content in the case of fasting, the protein will"Forced"The conversion into heat energy is consumed and does not play a nutritional tonic role.
Myth 3: Eating too many eggs.
Although eggs are good, if you eat more than three or more eggs a day, you must control them, because excessive consumption of eggs will increase the burden on the liver and kidneys and damage the function of the kidneys. Ordinary people have one a day, and pregnant women, mothers, frail people and patients recovering from major surgery need to increase good protein, and can eat 3 or 4 eggs a day, but not more.
Myth 4: Fried eggs.
Many people like to eat fried eggs, especially the ones that are fried golden brown at the edges. But in fact, the high molecular weight protein contained in the egg white will become low molecular weight amino acids on the edge of the burnt egg, and its nutrition has been destroyed, and even endanger human health. The best way to eat eggs so that the nutrients of the eggs are not lost to the greatest extent is to boil the eggs.
Myth 5: Don't care about the expiration date of eggs.
We all know that expired food cannot be eaten, so do you know how long the shelf life of eggs is? The shelf life is about 40 days at 2 5 degrees, 15 days at room temperature in winter, and 10 days at room temperature in summer, so eggs must not only be stored at the right temperature, but expired eggs must not be eaten.
