1. The advantages of eating eggs in the morning
1, supplement nutrition
In the field of nutrition, eggs have always been known as "all-nutritious food". Protein in eggs is closest to human body, and its absorption rate is better than milk, meat or soybean. The price is not expensive, but the content of protein is very high, which is twice that of sea cucumber.
Eggs are rich in fat-soluble vitamins, including vitamins A, D and K, which are very important for human health. From the perspective of Chinese medicine, eggs are a unique "balanced" food.
2. Reduce blood lipids
Eggs contain precious lecithin, which can help lipid metabolism and help reduce blood lipids. But it is only an auxiliary effect, and the medicine should be taken according to the doctor's advice!
Step 3 prevent heart disease
The fat in egg yolk is mainly monounsaturated fatty acid, more than half of which is oleic acid, the main component of olive oil, which is beneficial to prevent heart disease.
4, clearing heat and enriching blood
Li Shizhen pointed out in Compendium of Materia Medica that the egg white is slightly cold and the egg yolk is slightly warm; Egg white can clear heat, egg yolk can enrich blood, and its effect is comparable to Ejiao.
5. Protect your eyesight
Lutein and zeaxanthin, two antioxidants in egg yolk, can protect eyes from ultraviolet rays. They also help reduce the risk of cataracts. Eating an egg in the morning is also good for computer users who use their eyes too much.
Step 6 protect the liver
Protein in eggs can repair liver tissue damage. Lecithin in egg yolk can promote the regeneration of liver cells and enhance the metabolic function and immune function of the body.
7. Prevention and treatment of arteriosclerosis
American nutritionists and medical workers use eggs to prevent atherosclerosis. They extract lecithin from eggs and walnuts and give it to cardiovascular patients 4-6 tablespoons a day. After 3 months, the patient's serum cholesterol decreased significantly.
8, delay aging
Eggs contain almost all the nutrients the human body needs. One of the longevity experiences of many old people is to eat an egg every day. Many folk health medicated diets in China are also inseparable from eggs, such as Polygonum multiflorum boiled eggs and vinegar soaked eggs.
9, help to lose weight
Eating eggs for breakfast can reduce the calorie intake for lunch and the whole day, and play a role in controlling weight.
Studies show that people who eat eggs for breakfast lose 56% more weight and have more energy than those who eat carbohydrates for breakfast.
10, improve memory
Egg yolk is rich in lecithin, sterol, calcium, phosphorus, iron, vitamin A, vitamin D and B vitamins. It has a great influence on the nervous system and physical development. Lecithin is digested by human body, which can release choline, promote brain development, improve memory, help improve memory and make attention more concentrated.
Therefore, it is very necessary for office workers and students who use more brains to eat an egg for breakfast. This is also necessary for some elderly people with Alzheimer's disease.
2. Taboos for eating eggs
1, with sugar and soybean milk.
Similarly, eggs can't be eaten with soy milk. We know that mothers carefully prepare breakfast for their children every day, hoping that their children can get enough nutrition in the morning. So many mothers put frangipani in soybean milk. Or let the children quench their thirst with soy milk after eating eggs. In fact, drinking soybean milk with strong nourishing effect alone contains a special substance called trypsin, which combines with ovalbumin in egg white, causing the loss of nutrients and reducing the nutritional value of both.
Step 2 eat raw
If you think eating raw eggs is more nutritious, you are all wet! It is understood that the nutritional value of boiled eggs is higher than that of fried eggs, fried eggs and raw eggs. Immature eggs contain a lot of Escherichia coli, which is easy to cause diarrhea when entering the esophagus. Therefore, eggs should be cooked at high temperature and eaten after killing bacteria. In addition, raw eggs contain avidin, which will affect the absorption of biotin in food, leading to "biotin deficiency" such as loss of appetite, general weakness and muscle pain. There is also anti-trypsin, which will destroy the digestive function of the human body. Another thing to note is that when you beat eggs, you should be careful of the contaminated bacteria on the eggshell!
Step 3 eat overnight
If the eggs are completely cooked, they can be reheated the next day. However, hard-boiled eggs can't be eaten after one night! If the eggs are not completely cooked, it is easy to breed bacteria in the case of improper storage, leading to gastrointestinal discomfort and flatulence. Some people think that the longer the eggs are boiled, the better, which is also wrong. Because the eggs are cooked for too long, ferrous ions in the yolk combine with sulfur ions in protein to form insoluble ferrous sulfide, which is difficult to be absorbed. Pay special attention not to scorch the edges when frying eggs, because the high molecular weight protein contained in egg white will be converted into low molecular weight amino acids, which can often form chemicals harmful to human health at high temperature.
Step 4 soak in cold water and eat
I believe many people have done such a thing, that is, boiled eggs are put in cold water, and separated by using the different expansion degrees of egg protein and eggshell, but it will become easy to peel. Originally, the surface of fresh eggs has a layer of protection.
Membrane, in order to make the water in eggs difficult to evaporate and prevent microbial invasion, but this protective film has been destroyed after cooking. At this time, the egg is put into cold water, and cold water and microorganisms can enter the egg through the bridge hole on the eggshell and the double-layer membrane in the shell. When you eat it, you will also eat bacteria.
Step 5 eat too much
Although the nutritional value of eggs is high, the more eggs you eat, the better. Eating too many eggs can easily lead to overnutrition and obesity. Increase the burden on the liver and kidneys. Excessive protein will overload the urea manufacturing system, and excessive intake of protein will produce a large number of chemicals such as ammonia, hydroxyl and phenol in the intestine, which is very harmful to human body. Abdominal distension, dizziness, limb weakness, coma and other symptoms are likely to occur, which is often called "protein poisoning syndrome".
Step 6 eat on an empty stomach
Eating eggs on an empty stomach affects gastrointestinal health. Especially when you wake up in the morning, you should eat something else to satisfy your hunger, preferably starch and cereal. Then add protein, which is beneficial to the absorption of amino acids. Generally speaking, if you eat eggs on an empty stomach, the protein in them will be directly decomposed into sugars to supply the energy needed by the body, so that protein will not be absorbed by the body.
