In recent years, there has been an increase in the number of children with precocious puberty. It is common for girls in grades 3-4 of elementary school to develop breasts or to have menstruation, for boys to grow moustaches and change their voices, and even for kindergarten children to have menstruation. Some parents say that precocious puberty makes children end their childhood prematurely, or a child has to face dealing with adult things. Most parents don’t pay attention to their children’s development before they develop, they always feel that their children are small and development is irrelevant to them based on their own experiences, and they don’t even think that their children will develop. Until one day, when they give their child a bath and find that their daughter’s breasts have grown, or their son’s voice has changed, they are shocked, nervous, and even scared, which is why they rush to take their child to the hospital for examination. With the development of medical technology, there are already good ways to control the treatment of precocious puberty, but after all, you need to use drugs to treat the cost, and parents will always have one or another worry, prevention of precocious puberty should be the first thing. There are many causes of precocious puberty, but most children’s precocious puberty is idiopathic central precocious puberty, which means that there is no specific disease, but only the early development of the second sex characteristics, that is, the early normal sexual development of adults. In recent years, there have been many observations and studies on the phenomenon of early development, and these data show that there is a close relationship between nutrition and precocious puberty. Too much animal food, that is, too much meat, can contribute to precocious sexual development. Animal foods contain a lot of protein, which enters the animal’s body and is digested into amino acids. Too many amino acids can initiate development. When animals are fed with feed rich in amino acids, they grow fast and mature early, and so do humans. On the other hand, most of the animals people eat nowadays are raised in captivity, and hormones are often added to the feed in order to promote rapid growth. Humans who eat too much of these animal foods will consume excessive amounts of hormones, prompting early development. The trace element zinc can improve appetite, but also has the role of promoting development. Some nutritional supplements such as chicken embryo, pollen, animal colostrum, royal jelly, etc. have high content of gonadotropic hormones and gonadotropin hormones, which can promote early development if taken for a long time. In the past two decades, I have seen a large number of children with precocious puberty, and most of them like to eat meat. Their parents and grandparents always want their children to have good nutrition, in their philosophy, chicken, fish, meat, eggs, milk, shrimp, crab, turtle, eel, chicken soup, fish soup, bone soup and other non-vegetarian food is good nutrition, so they let their children eat more non-vegetarian food from childhood, and over time, the children develop a hobby of eating non-vegetarian food, they do not have meat meals, a pound of shrimp or a bowl of braised pork ribs, a meal easily eaten; thirsty, do not drink water, milk as tea; do not eat vegetables, parents do not want to eat meat. Milk as tea; do not eat vegetables, parents insist that children eat, but also just eat a little meaningful ……. Many parents listen to neighbors, friends, colleagues say that a certain food nutrition is good, rather than save their own money, regardless of the needs of children do not need to buy children to eat, random zinc supplement or eat tonic situation is very common. Parents are happy to see that their children are growing fast and fat, unaware that the development of secondary sexual characteristics is quietly taking place. Children need rich and sufficient nutrition in the process of growth and development, but it should be reasonable, nutrition is enough, too much meat or partial food is not good for health. Too much meat and vegetables, diversified and balanced nutrition is the real good nutrition!
