The nutritional intake of preschool children in a kindergarten provides a scientific basis for nutritional catering guidance. Methods: Five-day dietary survey, physical examination and hemoglobin determination were conducted at the same time. Results: The intake of heat energy and protein reached the corresponding supply standard, and the intake of fat was excessive. Protein from animal and legume foods is slightly insufficient, and the proportion of plant protein is high. Among trace elements and minerals, the intake of calcium, zinc, vitamin B 1, vitamin B2 and retinol is low. The incidence of anemia was 4.4% and the incidence of obesity was 9.0%. Conclusion: The growth, development and dietary nutrition of children in this kindergarten need to be improved. We should pay attention to the rational nutrition of preschool children and take effective measures to improve their nutritional status. Children aged 2 ~ 6 are in a period of rapid growth and development, with vigorous metabolism, rapid development of brain and nervous system, continuous ossification of bones and gradual maturity and perfection of various system organs. The result of such rapid growth will inevitably consume a lot of nutrients. Some parents are not familiar with children's nutrition knowledge, which leads to some misunderstandings in children's nutrition arrangement. According to our investigation, the following problems generally exist in family dining arrangements: 1. Breakfast is simple and the calories are insufficient; 2. Rich dinner and overnutrition; 3. The food is monotonous and the recipe is narrow; 4. Fine staple food, ignoring coarse grains; 5. Eat snacks and eat less staple food. In view of the problems existing in children's family diet, this paper actively discusses the formulation, cooking and scientific and reasonable arrangement of balanced diet for children aged 2-6, and has accumulated some experience. 1. Make scientific, reasonable and balanced nutrition recipes to meet the needs of children's growth and development 1. Comprehensive and balanced nutrition and ensuring children's scientific nutrition are the material basis for children's growth and development. Only by providing children with comprehensive and adequate nutrition can they promote their healthy growth. The six nutrients that children need every day are protein, fat, carbohydrate, water, trace elements and vitamins. Children of different ages have different needs, so it is necessary to adjust the food structure and constantly improve the nutritional model of children's diet. Provide children with food every day, such as grains, beans, vegetables, fruits, milk and dairy products, meat, poultry, eggs, fish, etc., plus appropriate amounts of oil, salt and sugar, and keep a certain amount of these foods in a certain proportion and arrange them in their daily meals. The amount of various foods provided for children every day is as follows: this not only ensures that children have sufficient and balanced nutrition in their daily diet, but also maintains the basic characteristics that China's diet is mainly plant food, supplemented by animal food, and the energy source is mainly grain, and also ensures the quality of various nutrients. 2. There are many colors and varieties, so it is impossible for any one or more foods to fully meet the needs of children's growth and development. Only by reasonably matching different foods to form the nutrients needed by the human body can children get comprehensive and balanced nutrition. To this end, we seek new ideas on the variety and nutrition of food. (1) Rice flour collocation-the collocation of rice and pasta, and the collocation of porridge and pasta ensure that children consume carbohydrates from various combinations. (2) Coarse grains are mixed with flour and rice, such as sweet potato, corn, pumpkin, glutinous blood, rice kernels, rice, etc., to improve the nutritional value of food. (3) combination of dry and wet-combination of milk and biscuits, rice and soup, porridge and noon to improve the absorption rate of children's nutrition, increase water and achieve the function of supplementing nutrition. (4) Salty and sweet collocation-dry and wet desserts are matched with dry and wet salty snacks to control the excessive intake of sugar and salt, so that children can eat sugar and salt in a balanced way every day. (5) collocation of animal protein and plant protein-animal food (fish, meat, shrimp, chicken, duck, eggs, etc. ) and bean products (tofu, dried citron, venetian blinds, soybeans, red beans, etc. ) collocation, pay attention to the intake of plant protein, so as to ensure that children get high-quality protein, improve the supplementary function and physiological value of protein. (6) dark vegetables with light vegetables and fruits-dark vegetables are green leafy vegetables (vegetables, spinach, etc. ) and dark vegetables (carrots, cucumbers), which generally contain more trace elements and vitamins than light vegetables and fruits. Light-colored vegetables include root vegetables (potatoes, white radishes, etc. ) and yellow leafy vegetables (cabbage, soybean sprouts, etc. ). The vitamin C of citrus and sweet orange in fruits is higher than that of vegetables. Their reasonable combination and one hour before or after meals can ensure and supplement the intake and utilization of trace elements and vitamins. 3. Follow the laws of the four seasons, and strive to make children get the nutrition they need for growth and development in time (1). The weather is warm in spring, which is the time for children to grow up rapidly. We should provide children with foods rich in calcium and foods rich in vitamin D in time. (2) In summer, the hot weather is the season when children consume the most physical energy. We arranged for the children to eat more light summer food. (3) The dry weather in autumn is the best season for children to gain weight. It is necessary to provide children with high-calorie food in time to prevent them from being obese, and provide health-care nutritious soup with anti-allergic and anti-cold treatment in time to ensure that children get proper nutrition. (4) In winter, cold weather is the best season for children to store energy. On the one hand, it is necessary to store heat energy for children to resist the cold, on the other hand, it is necessary to provide them with growth needs, let them eat sweets in moderation, and provide them with healthy and nutritious soup with anti-cold and anti-virus effects every day.
