Eggs contain minerals such as protein, fat, vitellogenin, lecithin, vitamins, iron, calcium, potassium and so on, and are nutritious foods, among which lecithin and vitellogenin are especially needed for the physical development of infants and adolescents. But when eating eggs, you should pay attention to two "calculations" and three "unsuitable".

These two "calculations" are:

1, calculate the food intake. A one-year-old or two-year-old child needs about 40 grams of protein every day. In addition to ordinary food, it is enough to add 1 or 1 half an egg every day. Babies need to eat egg yolk to supplement iron. At first, you can only grind 1/4 egg yolk, and then gradually increase it to 1/2- 1. If eating too much exceeds the child's needs, the child's gastrointestinal tract can't bear it, which will lead to digestive and absorption dysfunction, causing indigestion and malnutrition.

2. Calculate the time to boil eggs. The time for boiling eggs must be well controlled, usually 8- 10 minutes. If the egg is boiled too raw, the avidin in the egg cannot be destroyed, which will make biotin inactive and affect the absorption of biotin by the body. It is easy to cause biotin deficiency, fatigue, loss of appetite, muscle pain, and even hair loss and dermatitis, which is not conducive to eliminating bacteria and parasites in eggs. It is not good to cook it too hard. Because it takes a long time to cook, the structure of protein becomes tight, and it is difficult to contact with gastric juice, so it is difficult to digest.

These three "disadvantages" are:

1 and babies before half a year old should not eat egg white. Because their digestive system is underdeveloped, the permeability of intestinal wall is high, and the albumin molecules in egg white are small, sometimes they can directly enter the baby's blood through the intestinal wall, which makes the baby's body allergic to conductive protein molecules and causes eczema, urticaria and other diseases.

2, it is not appropriate to eat fried eggs. Because when frying eggs, the eggs are wrapped in oil, and the high-temperature oil will also scorch some protein, which will destroy amino acids such as lysine and lose its nutritional value. After eating, it is not easy to contact digestive juice in the mouth and stomach, which affects digestion.

3. Children with fever should not eat eggs. After eating egg protein, it will produce "extra" calories, which will increase the calories in the body, which is not conducive to the rehabilitation of sick children.
