　　Eggs contain a lot of cholesterol. Eating too many eggs will greatly increase the intake of cholesterol, causing excessive blood cholesterol levels and causing atherosclerosis and cardiovascular and cerebrovascular disease. disease occurrence. Taking mothers as an example, one egg contains approximately 250 mg of cholesterol, and 10 eggs contain approximately 2,500 mg of cholesterol. This amount is nearly 10 times the normal intake. In addition, the fat contained in eggs is saturated fatty acid. Excessive intake will inevitably cause a sharp rise in serum cholesterol and promote the occurrence of atherosclerosis and cardiovascular and cerebrovascular diseases.

　　Second, eating more eggs can easily lead to overnutrition and obesity.

　　women Postpartum During breastfeeding, the daily energy requirement is generally about 2800 to 3000 kcal, and the protein requirement is 90 grams. For example, eating 10 eggs a day is equal to 70 grams of protein, 60 grams of fat, and about 820 kcal. , in addition, wet nurses also need to eat a certain amount of staple food, chicken, fish, meat, soy products, vegetables and fruits, etc. The daily caloric intake can reach 3500-3800 kcal, and the protein and fat intake can reach 120-140 grams. This far exceeds their actual daily nutritional needs, resulting in overnutrition, which can cause excess fat to accumulate in the body and cause obesity.

　　Third, eating more eggs will cause nutritional imbalance in the body, thus affecting healthy。

　　Our daily diet is composed of a variety of foods. A reasonable and balanced diet is required to contain various nutrients needed by the human body, and requires that various nutrients should have appropriate proportions in the diet. Because various nutrients coordinate and restrict each other to function in the body. This way, the body can develop properly and stay healthy. At all times and in all countries, no matter what kind of food, although it has high nutritional value, it cannot contain all the nutrients needed by the human body. Long-term consumption of a food can lead to an excess of certain nutrients and a deficiency of others. Eggs are no exception. Eggs themselves cannot supply all the nutrients needed by the human body. For example, they do not contain carbohydrates and their vitamin C content 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 lack or excess of other nutrients.

　　Fourth, eating too many eggs will increase the burden on the liver and kidneys.

　　The 8 essential amino acids required by the human body can be met by eating 1 to 2 eggs a day. Since the body no longer needs it and will no longer absorb it, it will be converted into fat and accumulated in the body or wasted as calories. Moreover, the protein catabolism products of those eggs eaten in excess will increase the burden on the liver. A large amount of nitrogen-containing waste produced after metabolism in the body has to be excreted through the kidneys, which will directly increase the burden on the kidneys. Therefore, eating too many eggs is not good for the liver and kidneys.

　　So how many eggs are best to eat a day?

　　From a nutritional point of view, in order to ensure a balanced diet and meet the needs of the body without causing excessive nutrition, under normal circumstances, elderly It is better to eat 1 to 2 pieces a day. For young and middle-aged people who are engaged in mental work or light physical work, it is more appropriate to eat 2 eggs a day. ； Those who are engaged in heavy physical labor and consume a lot of nutrients can eat 2 to 3 eggs a day. ； Teenagers and children, due to their long body and fast metabolism, can also eat 2 to 3 pieces a day. Pregnant women, parturient women, nursing mothers with weak health, and patients recovering from major surgery need more high-quality protein, so they can eat 3 to 4 eggs a day, but not more.

　　Tip: How many nutrients are in eggs?

　　A medium-sized egg, weighing about 50 grams on average, can provide 6 grams of protein, 5 grams of fat, 72 kcal of energy, 23 mg of calcium, 89 mg of phosphorus, 1.2 mg of iron, 612 international units of vitamin A, 0.07 mg of thiamine, 0.13 mg of riboflavin, 0.04 mg of niacin, and 300 mg of cholesterol. If we compare an egg with 50 grams of lean meat, the quality of the protein and fat in the egg is better than that of lean meat, and the vitamin content is also higher, but the price is cheaper than lean meat. From both nutritional and economic considerations, eating eggs is more cost-effective.
