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 better for the elderly to eat 1 ~ 2 capsules a day. For young and middle-aged people, it is more appropriate to eat 2 eggs a day if they are engaged in mental or light physical labor; Those who are engaged in heavy physical labor and take more nutrients can eat 2 ~ 3 eggs a day; Teenagers and children can take 2 ~ 3 capsules a day because of their long body and fast metabolism. Pregnant women, lying-in women, weak nursing mothers and patients recovering from major surgery can eat 3-4 eggs a day, but not more, because they need to increase the quality of protein.

Eggs are a kind of nutritious food. An egg weighs about 50 grams, contains 7 grams of protein and 6 grams of fat, and generates 82 kilocalories. The amino acid ratio of egg protein is very suitable for human physiological needs, easy to be absorbed by human body, with a utilization rate of over 98% and high nutritional value. Eggs are rich in calcium, phosphorus, iron, vitamins A and B, as well as various vitamins and trace elements necessary for human body. They are good supplements for children, the elderly, pregnant women, patients with hepatitis, tuberculosis and anemia, and patients in recovery after surgery.

Although eggs are good, we should pay attention to science in consumption.

The harm of eating too many eggs is

1, eggs contain a lot of cholesterol, and eating too many eggs will greatly increase the intake of cholesterol, leading to high cholesterol content in the blood, causing atherosclerosis and cardiovascular and cerebrovascular diseases.

2. Eating too many eggs can easily lead to overnutrition and obesity. During postpartum lactation, women generally need about 2,800 ~ 3,000 kcal per day, and protein needs about 90g. For example, eating 10 eggs every day is equivalent to eating 70g of protein and 60g of fat, which is about 82 0 kilocalories. In addition, lactating mothers should eat a certain amount of staple food, such as chicken, fish, meat, bean products, vegetables and fruits. The daily calorie intake can be achieved. This far exceeds their daily actual nutritional needs, resulting in overnutrition, which will lead to the accumulation of excess fat in the body and the formation of obesity.

3, eating too many eggs will also cause nutritional imbalance in the body, thus affecting health. The daily diet consists of a variety of foods. A reasonable and balanced diet needs all kinds of nutrients needed by the human body, and all kinds of nutrients should have an appropriate proportion in the diet. Because all kinds of nutrients play a coordinating and restricting role in the body. Only in this way can the body develop normally and stay healthy. Eggs themselves can't supply all the nutrients needed by the human body. For example, without carbohydrates, the content of vitamin C is almost zero. Therefore, eating too many eggs will inevitably reduce the intake of other foods and make the intake of various nutrients unbalanced. Over time, it is easy to cause related diseases due to the lack or excess of other nutrients.

Eating too many eggs will also increase the burden on the liver and kidneys. Eating 1 ~ 2 eggs a day can meet the eight essential amino acids needed by the human body. Because the body no longer needs it, it will not be absorbed and utilized, but will be converted into fat to accumulate in the body or wasted as heat. Moreover, if you eat too many eggs, protein's catabolic products will increase the burden on the liver, and a large amount of nitrogen-containing waste produced after metabolism in the body will be excreted through the kidneys, which will directly increase the burden on the kidneys, so eating too many eggs is not good for the liver and kidneys.
