1. A balanced diet. According to the daily requirements of children aged 3-6 for various nutrients, the nutrition budget before eating and the nutrition accounting after eating are carried out. According to the seasonal characteristics, eight kinds of food are selected to arrange the supply of four nutrients (vitamin A, carotene, calcium and riboflavin) that children are easy to lack in partial eclipse habits. Lean, vegetarian, reasonable in thickness, sweet and salty, and eat less sweets and fried foods; Mainly cereals, supplemented by animal food; Coarse grains should be reasonably matched with flour and rice, which can not only complement each other in nutrition, but also contain crude cellulose, which can stimulate gastrointestinal peristalsis, reduce chronic constipation and promote children's growth and development.

2. Cook scientifically and maintain nutrition. Scientific cooking is an important link to ensure the quality of food and preserve the nutritional components of food. The meals made by scientific cooking methods are not only good in color, fragrance, taste and shape, but also meet the requirements of nutrition and hygiene. First of all, we should wash vegetables scientifically, pay attention to washing before cutting, and don't cut before washing to reduce the loss of water-soluble nutrients. It is best to soak some vegetables in water for a period of time to effectively remove eggs and pesticide residues parasitic on vegetable epidermis.

The cooking principle to reduce the loss of nutrients in vegetables is to stir fry quickly. According to some experimental reports, the average preservation rate of vitamin C in leafy vegetables is 60~70%, while the preservation rate of carotene can reach 76~96%. Pay attention to adding salt too early when cooking, which will lead to the loss of water-soluble nutrients. It can be seen that the preservation of nutrients is related to cooking techniques and skills. Unscientific cooking will cause nutrient loss or destruction.

3. Delicious food is more nutritious. For children who are growing vigorously, it is more important to eat delicious food and pay attention to nutrition. Some parents think that it is good to give their children nutritious food, but they don't pay attention to eating vegetables and balanced nutrition. In fact, vegetables are called a treasure house of vitamins. 100 grams of vegetables contains 2600 effective units of vitamin a and 4 100 units of carotene. They contain 65,438+000 mg of vitamin C and very rich in vitamin B. These vitamins have the function of assisting glutamic acid and pantothenic acid, and are indispensable substances for improving brain function.
