During puberty, girls gain an average of 5 to 7 centimeters per year, and boys gain an average of 9 to 10 centimeters per year, lasting 2 to 3 years. Puberty is a transition period from childhood to adulthood, and it is the “flowering years” of growth and development. Under the influence of hormones, height grows rapidly, and it is the second growth and development peak period after birth. There are obvious differences between boys and girls. Girls generally enter puberty at the age of 11 to 12, and most boys enter puberty at the age of 13 to 14. Children whose growth spurt occurs earlier will also stop growing in height sooner. Due to the rapid growth and development of puberty, the body needs nutrition will also increase accordingly, so in this stage must give the child more food rich in protein, vitamins and a variety of trace elements, balanced nutrition, in order to facilitate puberty body growth.
