Child development age

There are certain limits to the age of children's growth and development. During this period, parents should give their babies more nutrients and let them exercise more. Only when the intensity of exercise is sufficient can their children's development become more complete and will not be affected by too many factors, thus preventing malnutrition.

Puberty refers to the period between the ages of 11 and 16 when children are in the process of physical and mental development. Its main characteristics are rapid and unbalanced physical and mental development. It is a period of complex development and full of contradictions.

Some scholars have pointed out that in recent decades, there has been a global tendency for humans to reach earlier biological maturity. This is mainly manifested in two aspects: the early onset of puberty and the shortening of the puberty period. This enables each generation to reach adult maturity earlier. This epoch-making phenomenon of accelerated development is influenced by many factors, including the rapid development of contemporary economy and science and technology, the popularization of modern civilization, and changes in global climate conditions.

This general trend of early puberty has brought many contradictions and problems to society and education, and has also made the imbalance in the physical and mental development of adolescent children and the various crises and difficulties more obvious.

Nutrition is the material basis for ensuring the normal growth, development, and physical and mental health of children. Children's need for nutrients is higher than that of adults. This is because two requirements must be met, namely, the needs of growth and development and activity. Infants and young children in particular grow and develop most rapidly, requiring large amounts of protein and other nutrients, so this must be given attention.

After weaning, children need to have a balanced diet and eat as many different foods as possible to ensure the need for energy and nutrients and maintain a balance between nutrients, so as to avoid malnutrition due to nutrient deficiency or obesity due to overnutrition, which will affect the normal growth of children. Therefore, it is very important to cultivate good eating habits in children from an early age and not to be picky eaters or eat snacks randomly.

In addition to maintaining a good appetite for children, they should also develop a regular life, get enough sleep, and regularly participate in outdoor activities. This will help prevent disease, promote digestion and absorption of nutrients, and enable children to grow up healthily.

Effects of trace element selenium on children's growth and development

my country is a country with selenium deficiency, with 72% of its regions being selenium-deficient. Selenium is an essential trace element for the human body and is absolutely indispensable. Especially the special group of children, who are in a critical period of growth and development, have a relatively strong demand for the trace element selenium. Once the trace element selenium is deficient, it will have irreversible effects on children's growth and development.
