Question 1: Is it good for your health to eat protein every day? Eggs are nutritious: no more than three yolks a week. Fitness people may believe that they should eat raw eggs every day to get good protein; Pregnant women may think that eating an egg every day during pregnancy is nutritious; I also heard that children want to eat eggs to help their brains develop. You greedy sisters may have heard that egg white can be used as a mask and a conditioner. In fact, all these rumors are incorrect. Why? Nutrition of Eggs Eggs contain rich and complete protein, which belongs to meat and its substitute in the food pyramid, because its nutrition is similar to meat. No one will lack some nutrients because they don't eat eggs. On the contrary, eating raw eggs may be infected with Salmonella, and severe abdominal pain, vomiting and diarrhea may occur. Eating raw eggs can also hinder the absorption of a nutrient called biotin. Egg yolk is described as a brain tonic because it contains lecithin, but in fact, the body can also make lecithin. Unless there is something wrong with this function, there is no need to take extra lecithin from the diet. Moreover, soybeans and their finished products also contain lecithin, so it is even more unnecessary to use this as a reason to eat eggs. Therefore, anyone, including fitness people, pregnant women and children, need not eat eggs every day. As for the beauty effect of eggs, it turns out that it is not true. Under the microscope, egg white is a very large molecule, which can't be absorbed by skin and hair. The guidelines for the healthiest and healthiest diet of protein suggest that you should not eat more than three egg yolks per week, except for protein, and you should not consume more than 300 mg of cholesterol every day. It turns out that protein contains neither fat nor cholesterol, and it is a food close to pure protein, so the intake of protein is not restricted like egg yolk. Because fat and cholesterol are all in egg yolk, we should try to reduce the use of egg yolk when cooking. For example, steamed eggs can use four proteins and three yolks, and cakes can use two proteins instead of one egg. These methods can reduce the fat and cholesterol in recipes. Do you find that fried eggs need a lot of oil? It turns out that a boiled egg contains 72 calories, but an fried egg contains 120 calories! Editor: Nutrition of Egg Yolk and Protein Eggs of chickens, ducks, geese and other birds are basically the same in nutritional composition, mainly composed of egg yolk, egg white (that is, protein) and eggshell. Eggs each weigh about 40-50g, and duck eggs 50-60g, of which yolk accounts for 32%, egg white accounts for 57%, and the rest 1 1% is eggshell. Egg white contains protein 13- 15% except about 70% water. Protein of eggs is rich in essential amino acids, and its composition ratio is very suitable for human needs. This kind of protein has the highest utilization rate in human body. Most of the fat in the egg is in the yolk, and it is dispersed into fine particles, which are easily absorbed. The contents of fat and cholesterol in egg yolk are relatively high, and inorganic salts and vitamins are mainly concentrated in egg yolk. Inorganic salts, calcium, phosphorus and iron are abundant, so egg yolk is a good source of iron for infants. Vitamin A, vitamin D and riboflavin are the main vitamins. Generally speaking, the nutritional value of egg yolk is higher than that of protein, but for children over 6 months old, eating whole eggs is naturally more comprehensive.

Question 2: What are the benefits of eating egg whites? Eggs are ideal natural food for human beings, and we should also pay attention to science in eating. For the elderly, it is better to cook, lie down, steam and toss eggs, because frying, frying and frying are delicious, but they are more difficult to digest. If eggs are processed into salted eggs, their calcium content will increase obviously, from 55 mg per 100 grams to 5 12 mg, which is about 0/0 times of that of fresh eggs, and it is especially suitable for middle-aged and elderly people with osteoporosis. It should also be reminded that you should never eat raw eggs. Some people think that eating raw eggs is nutritious, and this arc method is unscientific.

Question 3: The benefits of eating more protein are only disadvantages, but not benefits. I hope you will wake up in time.

Protein powder should be eaten in moderation.

For the special population in need, in addition to supplementing essential amino acids through food, protein powder can be appropriately selected as the supplement of protein, but the dosage of protein powder must be paid attention to. After protein is digested and absorbed by gastrointestinal tract, it needs to be processed by the liver and converted into human substances for human use. At the same time, nitrogen-containing substances such as ammonia, urea and creatinine, which are products of protein's metabolism in the body, need to be excreted by the kidney. If a person eats too much protein, it will increase the burden on the liver and kidney, which will have a negative impact on the human body. Therefore, protein is by no means the more the better. The highest intake of protein proposed in Dietary Guidelines for China Residents is 0.92g per kilogram of body weight, and if it exceeds this amount, it may harm human health. As a matter of fact, protein only needs to meet the needs of human metabolism. After the excess protein is digested and absorbed, the liver will convert them into hepatic glycogen or muscle glycogen for storage; If liver glycogen or muscle glycogen is enough, it is converted into fat and stored; Other metabolites produced by this transformation must be excreted from the kidneys. Excess protein not only makes people obese, but also increases the metabolic burden of liver and kidney, which may affect their functions over time.

It should be reminded that when we supplement protein, we should also pay attention to supplement carbohydrates (sugars), lipids, vitamins and minerals. Because the lack of these nutrients will not only affect the utilization and metabolism of protein, but also cause some diseases, which is very harmful to health.

Who should use protein powder with caution?

1. Patients with kidney diseases should strictly limit the intake of protein, and protein containing 9 essential amino acids is the main ingredient. The amount of protein should be limited to 20 ~ 40g/day.

2. Patients with liver diseases should appropriately increase the intake of protein due to obstacles in the processing and utilization of protein by the liver. However, for patients with hepatic coma and advanced cirrhosis, too much protein will increase the burden on the liver and aggravate the condition, so animal protein should be restricted. Because of its metabolism in the body, it will produce more ammonia, which can induce or aggravate liver coma, so such patients can choose some plant proteins rich in branched-chain amino acids, especially soybean proteins. Because branched-chain amino acids are mainly metabolized in muscles, they have protective effects on liver function.

3. Newborns should not eat protein powder. They should choose milk powder with protein content of10% ~ 20%.

4. Gout patients should avoid eating protein powder with soybean protein as the main component. Because the purine in soybean can increase uric acid in the body and promote or aggravate gout.

Question 4: What are the benefits of eating egg protein? It is best to put eggs in a pot with cold water, and boil them for another 3 minutes. At this time, the egg is heart-shaped, and the nutrients are most beneficial for the human body to absorb. Wash the fresh and undamaged eggs, put them into the pot with cold water, and after boiling, time them for 3 or 5 minutes respectively, and take them out for cooling. "3-minute egg", the egg white is cooked and soft, and the yolk is just cooked and slightly cooked. "5-minute egg", the egg white is cooked and tender, and the yolk is cooked but not hard. Take it out and stir it with cold water, and you can eat it.

Some small things that we often don't pay attention to in life will cause adverse factors to our health. The following is an excerpt from doctor Jiulin's statement on the Internet for my friends' opinions:

First, pay attention to avoid eating raw or immature eggs. Eggs will carry bacteria during the formation process. There are bacteria in raw or immature eggs, which may easily cause diarrhea, leading to loss of appetite and indigestion.

Second, pay attention to avoid eating boiled eggs. If the eggs are cooked for too long, a gray-green ferrous sulfide layer will be formed on the surface of the egg yolk, which is difficult to be absorbed by the human body. Protein will become hard and tough as it ages, which will affect appetite and is not easily absorbed by the human body.

Third, pay attention to the fact that eggs should not be cooked with sugar. Cooking eggs with sugar will generate a substance called glycosyl lysine due to high temperature, which will destroy the amino acid components in eggs that are beneficial to the human body, and this substance has a blood coagulation effect and will cause harm after entering the human body. If you need to add sugar to boiled eggs, you should wait until it is a little cool and put it into the stirring, and the taste will not be reduced.

Fourth, pay attention to scrambled eggs without monosodium glutamate. Eggs contain sodium chloride and a lot of glutamic acid. These two ingredients are heated to form sodium glutamate, which has a pure flavor. The main component of monosodium glutamate is also sodium glutamate. If monosodium glutamate is put into scrambled eggs, it will affect the synthesis of eggs themselves.

Sodium glutamate destroys the delicate flavor of eggs.

5. Boiled eggs should not be stored after being soaked in cold water, and they can be eaten directly after being soaked. Some people often soak boiled eggs in cold water, making use of the different thermal expansion coefficients of eggshells and proteins to make eggshells easy to peel off. However, this kind of eggs soaked in cold water cannot be stored.

Question 5: What are the benefits of eating raw egg whites? Some people think that eating raw eggs is more nutritious. In fact, eating raw chickens is very harmful to people's health.

First of all, raw eggs contain anti-enzyme proteins and anti-biological proteins. The former hinders the contact between protease in human stomach and protein, and affects the digestion and absorption of protein. The latter can combine with biotin in food to form substances that the human body cannot absorb. However, the above two harmful substances in raw eggs are destroyed once cooked, which no longer affects the absorption of nutrients by the human body.

Secondly, raw eggs often carry pathogenic bacteria, mold or parasitic eggs. Some parents use boiled water to pour eggs with sugar for their children to drink. Because the germs and parasitic eggs in eggs can't be completely killed, it is easy to cause diarrhea and parasitic diseases.

Therefore, eggs must be cooked and eaten, and it is best to eat steamed eggs. It is not advisable to wash eggs with boiling water, let alone eat raw eggs.

Question 6: What are the benefits of eating more protein? protein foods can be divided into two categories: plant protein foods and animal protein foods.

1, plant protein foods: bean products-bean chips, tofu, bean skin, dried bean curd, soybean milk, bean curd, yuba, bean sprouts, etc.; Peanuts, sesame seeds, and other dried fruits.

2. Animal protein foods: all kinds of livestock, poultry, seafood, fresh water products, eggs, liver, milk, cheese, etc.

Protein is an indispensable substance for life and the main component of cells. The muscles, internal organs, blood, skin, hair and nails of human body are all composed of protein. Without protein, there would be no life.

The nutritional value of protein is higher than that of protein.

Eating too much protein is harmful to kidney health.

Question 7: What will the egg white do? Egg white, also known as "protein" or "egg white", is the transparent liquid part around the yolk in the egg. Egg white was originally the cytoplasm of single-celled eggs, and its purpose was to provide nutrition for developing embryos. This is also the reason why protein is rich in nutrition and can be used as an ideal nutritional tonic. This article will fully introduce its nutritional value, and from now on, it can be used as a part of daily diet.

Egg white is one of the purest and richest sources in protein. Protein nutrition used by many bodybuilders is separated from egg white. Stallone in the movie will first put two eggs in a glass before starting training at 4 am, and then drink them raw. This story tells us that egg white is a good source of protein, which can help muscle building and serve as an ideal nutritional supplement for bodybuilding.

nutritional ingredient

Egg white is the most nutritious part of eggs. Egg yolk is not so nutritious, because it contains a lot of cholesterol, and consuming too much egg yolk is harmful to heart health. Here are some nutritional facts about egg white:

About 90% of egg whites are water.

Besides water, other parts of protein are composed of protein, minerals, vitamins, fat and glucose.

Protein is clear and transparent in its natural state. It turns white only when it is cooked. The change of color is due to the change of chemical properties, which means that long-chain amino acids break and form hard protein structure. This process is called degeneration.

Egg white contains no cholesterol, but a lot of protein.

In a standard-sized egg, protein provides about 20 calories. These 20 calories are from protein, carbohydrates and sodium.

The most interesting thing about protein nutrition is that it contains 40 different protein, each of which is very beneficial to the body. In addition, it also contains minerals such as zinc, iron, copper, phosphorus, calcium and potassium. All these minerals are necessary for the health of hair, nails, bones and teeth.

Egg white mainly contains protein ovalbumin, which plays an important role in the metabolism of body enzymes and stores protein.

But it should be remembered that excessive consumption of egg white also has side effects, which will cause biotin deficiency. Therefore, eating too much protein is not good for your health. In addition, eating too much egg white may also lead to constipation and release excessive sulfur dioxide gas.

Protein contains vitamins B6, B 12, riboflavin and folic acid. Riboflavin is an essential element for the growth of body cells. Folic acid is important for maintaining heart health.

You can eat egg white in the form of boiled eggs, scrambled eggs and even fried eggs. After cooking, most of the nutrients in egg white can be preserved, and only a small part will be lost.

Question 8: What are the foods containing protein? What are the benefits of eating too much food in protein? protein is an essential nutrient for human life activities.

Muscle, blood and many enzymes are built by protein.

High-quality protein includes fish, eggs and milk beans, and a balanced diet is very important for protein's intake.

But it is not good to eat too much.

Question 9: Do you eat eggs to supplement protein? Is it good for fitness? 5 points of the benefits of eggs to the human body

Lecithin, triglyceride, cholesterol and vitellin in brain-strengthening and intelligence-improving egg yolk have good effects on nervous system and physical development, and can delay the mental decline of the elderly and improve memory. Lecithin is regarded as the bane of Alzheimer's disease by medical experts.

Protein in protecting liver eggs can repair liver tissue damage. Lecithin in egg yolk can promote the regeneration of liver cells, increase the amount of human plasma protein, and enhance the body's metabolic and immune functions.

Prevention and treatment of atherosclerosis American nutritionists and medical personnel used eggs to prevent and treat atherosclerosis according to the emulsification of lecithin in egg yolk, and achieved unexpected results.

Prevention of cancer Eggs contain more vitamin B2, which can decompose and oxidize carcinogens in the human body. Trace elements in eggs, such as selenium and zinc, also have anti-cancer effects. Japanese scholars have found that eggs also contain anti-cancer substances, namely, retinol and photopigment, and one egg contains about 0/0 microgram of retinol/kloc-,which can inhibit the proliferation of Epstein-Barr virus that induces laryngeal cancer and lymphoma.

Anti-aging eggs contain almost all the nutrients needed by human body, so they are called "ideal nutrition bank". Nutritionists call it the "complete protein model", and insisting on eating eggs in moderation is one of the experiences of many people who live longer.

The correct way to eat eggs

There are many ways to eat eggs. In terms of nutrient absorption and digestibility, boiled eggs are100%, scrambled eggs are 97%, tender fried eggs are 98%, old fried eggs are 81.1%,boiled eggs with boiled water and milk are 92.5%, and raw eggs are 30% ~ 50. It can be seen that boiled eggs are the best way to eat, but we should pay attention to chewing slowly, otherwise it will affect absorption and digestion. However, for children and the elderly, steamed egg soup and egg drop soup are the most suitable, because these two methods can make protein loose and easily be digested and absorbed. The content of vitamin C in eggs is not high, so it is best to eat eggs with proper amount of vegetables.

How many eggs is it appropriate to eat every day?

From the point of view of nutrition, in order to ensure a balanced diet, meet the needs of the body, and not be overnourished, under normal circumstances, it is appropriate for the elderly to eat1~ 2 eggs a day. Young and middle-aged people, those engaged in mental or light manual labor can eat 2 eggs a day; Those who engage in heavy physical labor and consume more nutrition can eat 2 ~ 3 eggs a day; Children should eat 2 ~ 3 eggs every day because of their long body and fast metabolism. Pregnant women, lying-in women, nursing mothers, people who are weak and patients who are recovering from major surgery need more excellent protein. They can eat 3-4 eggs a day, but not more.

Does eating eggs raise blood lipids?

In the past, people thought that although the nutrition of eggs was good, the yolk contained more cholesterol. Eating eggs often would cause the increase of blood lipids and promote the occurrence of atherosclerosis. Therefore, it was advocated that the elderly should eat less or not eat eggs. However, in recent years, studies have shown that eating eggs will not only cause an increase in blood lipids, but also reduce cholesterol and prevent diseases such as atherosclerosis, coronary heart disease and stroke.

The content of cholesterol in egg yolk is really high. An egg weighing about 50g has a yolk of15g, which contains about 280mg of cholesterol. However, if you eat 1-2 eggs a day, the cholesterol absorbed by the intestine is very limited, because foods such as cereals, beans, vegetables and fruits can also inhibit the absorption of cholesterol by the intestine. Under normal circumstances, the human liver also synthesizes cholesterol. When the cholesterol absorbed from the intestine increases, the amount of cholesterol synthesized in the liver will decrease, thus maintaining the relative balance of cholesterol in the blood.

Egg yolk is rich in lecithin, which is a strong emulsifier. When it is absorbed into the blood, it can make cholesterol particles smaller and keep suspended. This not only helps cholesterol to be used by tissues through the blood vessel wall, but also avoids the deposition of cholesterol on the blood vessel wall, so it helps to lower cholesterol. Therefore, nutritionists suggest that the elderly can eat 1 egg every day.

The correct way to eat eggs

Because egg yolk contains cholesterol, for a long time, many people equate eggs with cholesterol, thinking that eating eggs can increase blood lipids, so patients with arteriosclerosis, coronary heart disease and hypertension should not eat it. Some people even want to remove the yolk when eating eggs. Here, we are going to make a toast for eggs.

I eat eggs every day. When I went to Taiwan Province to give a lecture some time ago, I had a PET examination. The results showed that coronary artery calcification was rated as 0, which was the most ideal state. It can be seen that egg yolk is not equal to cholesterol, and eating egg yolk will not increase blood lipid and lead to arteriosclerosis. ...> >

Question 10: Is it good to eat protein powder? What are the advantages and disadvantages? The function of 1. protein powder and its applicable objects

The so-called protein powder is generally a powder composed of purified soybean protein, casein, whey protein, or a combination of the above proteins, and its purpose is to supplement protein for individuals lacking protein. The main function of protein powder is to correct protein's malnutrition, and it is mainly suitable for patients whose body is in a negative nitrogen balance due to trauma, burns, large area skin ulceration, major surgery, tumor radiotherapy and chemotherapy, etc. It can also be used for patients with insufficient intake or absorption of protein due to anorexia nervosa, functional dyspepsia and intestinal malabsorption. It can also be used for children in the growth period, pregnant and lactating women and the elderly with weak gastrointestinal function. It can be said that protein powder is not a supplement suitable for all healthy individuals.

2. protein that healthy people need every day

The daily protein requirement of a healthy adult is 0.8 ~1.0g per kg of body weight, and about 50 ~ 60g in total.

Protein required by healthy adults can be completely met by daily diet. Eating a proper amount of staple food (more than 6 pairs for men and more than 5 pairs for women), 1~2 bags of fresh milk (250 ~ 500ml) or the same amount of yogurt or soybean milk, 1 egg, 3 pairs of lean meat, 2~3 pairs of bean products, etc. every day is enough to supplement 50 ~ 60g of protein required by a healthy individual. If protein powder is supplemented on this basis, the intake of protein will exceed the standard, thus putting the human body in a state of "high protein load".

3. The adverse effects of excessive supplementation of protein by healthy people.

Excessive intake of high protein will bring many adverse effects on human health. For example, long-term intake of high protein will increase the burden on the kidney, and even make the kidney in a state of "overload" for a long time, which may accelerate its aging and damage; Also, excessive intake of protein can promote the dissolution of calcium from bone and increase the loss of calcium. Long-term intake of high protein will increase the risk of osteoporosis.

To sum up, it is not difficult for us to draw the conclusion that:

1. protein should and can be supplemented by a reasonable daily diet;

2. Healthy adults don't need to supplement protein powder on the basis of reasonable daily diet.

3. For patients or specific groups who can't eat normally, the demand for protein is increasing, protein is malabsorption, and protein is consumed too much, it is necessary to supplement protein powder under the guidance of nutritionists.

Here I would like to introduce two kinds of protein powder:

Mixed protein powder

The first thing I met with you was the mixed protein powder, which came to China to meet the ordinary people at the earliest time, and it is also the only protein powder nutritional food that can be understood by the public in China's big cities.

What is a mixed protein powder? Mixed protein powder is made by blending different kinds of protein powder such as soybean protein, whey protein and egg protein in different proportions. Because protein, a plant type, is matched with protein, an animal type, the properties of the mixed protein powder are milder. Plant protein contains unique natural estrogen, which can regulate women's endocrine system, reduce the discomfort of menopausal syndrome, improve mental state, whiten skin and resist aging, so it is especially suitable for middle-aged and elderly women.

Whey protein powder

100% pure whey protein powder is a protein powder product with the highest nutritional value and the most advanced production technology in the world.

It uses whey protein extracted from high-quality milk as raw material (80% of milk is cool protein, and whey only accounts for 20%), and it is processed at ultra-low temperature by using advanced ion exchange and micro-air filtration technology, so as to ensure that high-quality protein is completely preserved and can be quickly absorbed by human body during the production and processing.

Pure whey protein powder contains only the complete amino acid group naturally occurring, and various whey protein isolates such as β-lactoglobulin, α-whey protein, glycogen oligopeptide, immunoglobulin, peptone, serum albumin, lactoferrin and lactoperoxidase. Such comprehensive and high-quality whey protein powder is not only a nutritious meal for ordinary people besides three meals, but also a necessary nutritional supplement for sports enthusiasts and professional athletes, and it is also a strong shield for patients with diseases to fight against diseases.

In recent studies, whey protein has been found to be competent for various immune challenges, including extremely intense carcinogenic chemicals. The use of whey protein concentrate can inhibit the growth of cancer cells and have a strong immune response to carcinogenic chemicals. If the patient is given 30 grams of whey protein concentrate every day, the size of the tumor will deteriorate. This is > >
