Hello, my friend! From the point of view of nutrition, healthy adults usually eat 1-2 eggs a day in order to ensure a balanced diet, meet the needs of the body and avoid overnutrition; It is best for the elderly to eat one every day; It is more appropriate for mental workers to eat two eggs a day; Pregnant women, lying-in women, lactating women and the infirm can eat 2-3 eggs a day, not more. Boiled eggs are the best way to eat, but you can't overcook them. The cholesterol content of an egg yolk is 2/3 of the cholesterol that a healthy adult should consume every day. By controlling the intake of meat and dairy products, such as eating cheese-free vegetables and a lot of fruits, whole grains, low-fat foods and a small amount of lean meat, poultry and fish, the cholesterol in a week should not exceed 7, that is, the average cholesterol should not exceed 1, but it also depends on the situation of your other foods, such as your meat. Salted eggs are good, don't worry about too much fat. However, the time to boil eggs should not exceed 5 minutes. The longer the nutrition time, the less easy it is to be absorbed. The nutrition of eggs in 3 minutes is the easiest to absorb, and the nutrition of eggs in 5 minutes is more comprehensive and balanced. Almost all the nutrition is needed by the human body. Egg white and egg yolk have extremely high protein physiological value, are easy to digest and absorb, and the utilization rate can reach over 95%, so they are natural foods with relatively complete prices. How many eggs should I eat a day? First, let's see how much nutrition we can get from an egg. A medium-sized egg, with an average weight of about 50g, can provide protein 6g, fat 5g, calories 72kcal, calcium 23mg, phosphorus 89mg, iron1.2mg, vitamin A6 12 IU, thiamine 0.07mg, riboflavin 0.13mg, and so on. Considering both nutrition and economy, eating eggs is more economical. In recent years, many people are afraid of cholesterol because they know that the blood cholesterol of people with atherosclerosis and coronary heart disease has increased. They are afraid that eating egg yolk will cause arteriosclerosis, so they dare not eat eggs. This kind of worry is unnecessary. Under normal circumstances, cholesterol is harmless and an indispensable substance for human body. In the body, cholesterol is not only one of the basic substances to form cells, but also can synthesize several important hormones and convert them into vitamin D3 in the body. On the other hand, cholesterol in human plasma is not all from food, but from exogenous and endogenous sources. Exogenous comes from food, and all meat, eggs and animal fats contain cholesterol. It is estimated that you should eat about 500 mg a day. If you eat less animal food, you will not reach this figure. Endogenous is synthesized by the body itself, and about 1.0 ~ 1.5g is synthesized every day, which is far more than what is eaten from food, so most of the cholesterol in the body is made by the body itself.
