According to the World Health Organization, the daily calorie supply for children aged 7-9 is 2,200 kcal, 10- 12 years old is 2,600 kcal for boys and 2,340 kcal for girls. Protein's requirement increases with the enhancement of activity and muscle development, 60g per day for 7 ~ 10 years old and 70g per day for 10 ~ 12 years old. High-quality protein should be guaranteed, and its heat supply should account for 1 1% ~ 14% of the total heat. Due to the rapid growth of bones, there is a great demand for minerals, especially calcium, zinc, iron, copper and other trace elements and various vitamins. Fat intake should not be too high, and its heat supply accounts for about 25% ~ 30% of the total heat, of which 1/2 comes from vegetable oil. If children's nutrition supply is insufficient at this time, they will be tired or their resistance will decrease. If protein is insufficient, it will lead to stunting, weight loss, even mental retardation, inattention and other symptoms, so we should arrange our diet reasonably according to its characteristics. Proper tonic can eliminate fatigue and supplement consumption, which is conducive to the healthier growth of children.

1 1 and 12-year-old children's dietary arrangements.

According to the needs of children aged 1 1 and 12, the following five types of food must be included in the dietary arrangement:

The first kind of food: mainly cereals, such as rice, steamed bread, noodles, corn, sweet potatoes and so on. , mainly supply carbohydrates, protein and B vitamins to provide calories.

The second kind of food: animal-based food, such as meat, eggs, milk, fish, etc. To supply high-quality protein, fat, minerals, vitamins A and B ..

The third kind of food: mainly beans, such as soybeans and their products, to supply plants with high-quality protein, fat, minerals, dietary fiber and B vitamins.

◆ The fourth kind of food: mainly vegetables and fruits, supplying vitamins, minerals and dietary fiber.

The fifth food: cooking oil and sugar. Edible oil should be mainly vegetable oil to provide heat and essential fatty acids.

Children's dietary and nutritional taboos

In order to ensure the normal growth and health of children, some foods should not be given to children, otherwise it will bring harm to their growth and health. There are mainly the following kinds of food:

Popcorn with high lead content is easy to cause children's growth retardation and disease resistance decline.

Fat children often eat more fat, which will not only cause obesity, but also affect the absorption of calcium ions, which may lead to long-term calcium deficiency in the body.

In the production process of canned food, additives such as pigments, flavors, sweeteners and preservatives should be added. Because children's development is not yet mature and the function of liver detoxification is not perfect, these additives have a great impact on children's health.

Coke beverage contains a certain amount of caffeine, which has a strong exciting effect on the central nervous system and is potentially harmful to human body.

Milk candy Milk candy remains between children's teeth and is quickly converted into acidic substances by oral bacteria. However, a small amount of organic acid is generally added to milk candy, which will loosen, decalcify and dissolve tooth tissue, and even cause dental caries in severe cases.

Some food pigments in colored foods are artificially synthesized by chemical methods, which will interfere with the normal metabolism of human body and the normal functions of various active enzymes, and accumulate in the body will also lead to chronic poisoning. Excessive consumption may also affect the nervous system, leading to ADHD in children.

The main ingredient of jelly is sodium alginate. Eating too much will affect the digestion and absorption of protein and fat, and also reduce the absorption of iron and zinc, which is not good for children's growth and development.

Bubble gum contains many additives, such as plasticizer. If it is contained in the mouth for a long time, it is easy to swallow the gum base, which has a bad influence on children's health.

ADHD and Dietary Nutrition in Children

According to analysis, the causes of ADHD in children (also known as mild brain dysfunction syndrome) are various. For example, it is related to the mother's illness during pregnancy, premature delivery, dystocia, abnormal brain physiology and biochemistry, genetic factors and so on. There are several factors in the diet:

● It is related to the intake of food additives (such as flavors) and artificial colors. China's "Hygienic Management Measures for Food Additives" stipulates: "Except for fortifiers, artificial sweeteners, pigments, flavors, sodium glutamate and inappropriate food additives shall not be added to the main and auxiliary foods specially designed for infants.

● Related to high-sugar diet: High-sugar diet can make neurotransmitters such as catecholamine insufficient, which in turn leads to ADHD.

● It is related to excessive lead intake: 65,438+00% of American ADHD children are related to excessive lead intake. Lead can lead to changes in brain chemistry and neurotransmitter metabolism, so that visual motor function, memory, feeling, visualized thinking and behavior change, and ADHD symptoms appear. Therefore, children should avoid using lead-containing utensils and eat less lead-containing foods, such as popcorn, preserved eggs, shellfish, red shrimp, lettuce and lead-containing (mostly polluted) vegetables.
