Vitamins, children whose growth is large, need more than enough protein, fat, and carbohydrates, but they must also supply enough vitamins to meet their growth and development needs.
Each vitamin has its own unique function, and some vitamins function synergistically.
Vitamin A is particularly important for infants and young children. Visual organs - The development of the eye is inseparable from vitamin A, which maintains the healthy growth and development of the retinal epithelial cell tissue and enhances its resistance. Vitamin A is fat-soluble and can be stored in the body. If the child does not like to eat foods rich in vitamin A (such as liver) and do not like to eat foods rich in carotene (such as carrots), vitamin A deficiency may occur.
Vitamin C can reduce the trivalent iron, which is hardly absorbed by the human body, into easily absorbed divalent iron, promote the absorption of iron in the intestines, and reduce the ferric iron in plasma transferrin to bivalent iron, thereby increasing the utilization of iron. To prevent iron deficiency anemia in children. On the other hand, vitamin C can weaken the toxicity of the virus, weakening its virulence, large doses of vitamin C can also prevent the virus flu. In addition, vitamin C can improve and protect your child's myocardial function.
B vitamins Vitamins B1, B2, B6, niacin, etc. are related to calorie metabolism. The children in the growth and development period are very prosperous. The deficiency of any one of the B vitamins will affect the metabolism of calories and lead to anabolic failure. As a result, growth and development are hindered. If the child lacks nicotinic acid, ecdysis can also occur, affecting the development of the nervous system, and severe dementia.
Vitamin D is closely related to skeletal metabolism. Children are at the peak of height growth, and are the phase of large calcium storage of bones. The storage of calcium is inseparable from the participation of vitamin D, so the lack of vitamin D in children can affect bone mineral calcification. In severe cases, it can cause rickets and rickets. For children who are often exposed to outdoor activities and receive sunlight, there is generally no shortage of vitamin D. If your child seldom bask in the sun, vitamin D should be supplemented by a doctor.
As soon as possible, the physical activity of the body is the child's nature, and the amount of activity increases, and the consumption of calories is bound to increase. Children who are trained in exercise consume more calories. Therefore, it is necessary to increase various vitamins related to nutrition metabolism in time. The demand for these vitamins is directly proportional to the amount of calories burned. Usually, the amount of vitamins B1, B2, and niacin is 4 mg for each 4184 kJ (1000 kcal) consumed.
Compared to adults, the relative need for vitamins is higher for children during growth. In this sense, even if the child does not have a partial eclipse, he needs a balanced and balanced vitamin supplement.
Some children are full-fledged and weigh more than their average weight. They seem to be very healthy, but they are prone to fever and colds. After examination, they have low levels of hemoglobin and anemia. In the treatment of anemia, in addition to supplying protein and iron, vitamin B12 and folic acid should also be supplemented.
When supplementing various vitamins, the dose must be balanced. Excessive intake of a vitamin can cause or exacerbate the deficiency of other vitamins. If there is a lack of B vitamins in the diet, giving a large amount of vitamin B1 alone can increase the extent of nicotinic acid deficiency. Therefore, vitamin supplementation is best given at the same time, which is reasonable and necessary.
