★ Lecithin, triglyceride, cholesterol and yolk protein in brain-strengthening and intelligence-improving egg yolk have good effects on nervous system and physical development, which can delay the mental decline of the elderly and improve memory. Lecithin is regarded by medical experts as the bane of Alzheimer's disease.
★ Protecting the liver protein in eggs can repair the liver tissue damage. Lecithin in egg yolk can promote the regeneration of liver cells, increase the amount of human plasma protein, and enhance human metabolism and immune function.
★ Prevention and treatment of atherosclerosis American nutritionists and medical staff used eggs to prevent and treat atherosclerosis according to the emulsification of lecithin in egg yolk, and achieved unexpected results.
★ Preventing 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 phytochrome and phytochrome. An egg contains about 10 microgram of phytoflavin, which can inhibit the proliferation of EB virus that causes laryngeal cancer and lymphoma.
★ Anti-aging eggs contain almost all the nutrients needed by the human body, so they are called "ideal nutrition banks". Nutritionists call it the "complete protein model", and insisting on eating eggs in moderation is one of the experiences of many longevity people.
The correct way to eat eggs
There are many ways to eat eggs. In terms of nutrient absorption and digestibility, boiled eggs are 100%, scrambled eggs are 97%, tender fried eggs are 98%, old fried eggs are 8 1. 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. But 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 easy to digest and absorb. 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 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, it is generally appropriate for the elderly to eat 1 ~ 2 eggs a day. Young and middle-aged people, who are engaged in mental or light manual labor, can eat 2 eggs a day; Those who are engaged in heavy physical labor and take more nutrients can eat 2 ~ 3 eggs a day; Children have a long body and a fast metabolism, and eat 2 ~ 3 eggs every day. Pregnant women, lying-in women, nursing mothers, weak people and patients recovering from major surgery need more high-quality protein. They can eat 3-4 eggs a day, but not more.
Can eating eggs raise blood lipids?
People used to think that although eggs are nutritious, the yolk contains more cholesterol. Eating eggs regularly will lead to an increase in blood lipids and promote the occurrence of atherosclerosis. Therefore, some people advocate that the elderly should eat less or not eat eggs. However, in recent years, studies have shown that eating eggs can not only increase blood lipids, but also lower 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 of 15g and contains about 280mg of cholesterol. However, if you eat 1-2 eggs a day, the cholesterol absorbed by the intestine is very limited, because cereals, beans, vegetables, fruits and other foods will 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 by the liver decreases, thus maintaining the relative balance of cholesterol in the blood.
Egg yolk is rich in lecithin and is a strong emulsifier. When it is absorbed into the blood, it can make cholesterol particles smaller and remain suspended. This not only helps cholesterol to be utilized by tissues through the blood vessel wall, but also avoids the deposition of cholesterol on the blood vessel wall, thus helping to lower cholesterol. So 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 and think that eating eggs can improve blood lipids, so patients with arteriosclerosis, coronary heart disease and hypertension should not eat them. Some people even want to remove the yolk when eating eggs. Here, we want to repair eggs-
I eat eggs every day. Some time ago, when I went to Taiwan Province Province to give a lecture, I had a PET exam. The results show that the coronary artery calcification score is 0, which is 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.
