What nutritional supplements do adolescent students need?
Adolescence is in the thriving stage of growth and development, and the demand for various nutrients is much higher than that of adults. Therefore, nutrition issues are even more important. The function of nutrients is to form body, repair tissues, supply heat, supplement consumption, and regulate physiological functions. The nutrients that should be added during puberty include: (1) Carbohydrates. Adolescents need 25% to 50% more calories than adults. This is because adolescents have a large amount of activities, basic needs, and many additional nutrients for growth and development. The main source of calories is carbohydrates, which are cereals, so young people must ensure adequate appetite. (2) Protein. Proteins are the basis of growth and development. The body cells proliferate in large numbers and their constituents are all proteins. The protein requirement for children and adolescents during growth and development is 2-4 grams per kilogram of body weight per day. The human body's protein is mainly supplied by food, and eggs, milk, lean meat, soybeans, corn and other foods are all rich in protein, mixed edible, can make all kinds of food proteins complement each other, and nutrition is used rationally. (3) Vitamins. In growth and development, vitamins are essential. It can not only prevent certain diseases, but also improve the body's immune system. Most of the vitamins the body needs are from vegetables and fruits. Celery, beans and other vegetables contain a large amount of B vitamins; hawthorn, fresh dates, tomatoes contain a lot of vitamin C. (4) Minerals. Minerals are indispensable for human physical activity, especially for adolescents, who have a great need for minerals. Calcium and phosphorus are involved in the formation of bone and nerve cells. If calcium intake is insufficient or the ratio of calcium to phosphorus is not appropriate, it will inevitably lead to incomplete bone development. Milk and soy products are rich in calcium. Young people need more iron than adults. Iron is an essential component of hemoglobin. If iron deficiency occurs in the diet, it will cause iron deficiency anemia. In particular, women lose 50 to 100 ml of blood per menstrual period, and at least 15 to 30 mg of iron should be added. Rape and leeks are rich in iron. (5) Trace elements. Although trace elements are rare in the body, they play an extremely important role in the growth and development of adolescents. Especially zinc, China's daily dietary intake of zinc is 15 mg. Zinc-rich foods include animal liver and seafood. (6) Water. The youngsters are lively and active, require more water than adults, and intake 2500 ml of water a day to meet the metabolic needs of the human body. Inadequate intake of water can affect the body's metabolism and the discharge of harmful substances and wastes from the body. If you exercise a lot, sweat too much, but also increase the amount of drinking water. The intake of water here does not refer to the amount of water that is consumed, but the sum of the amount of water that is added to the water that is added to the food that is eaten.
