In recent years, news about children's precocious puberty has been frequently reported, and many parents have changed their color about it. Precocious puberty will not only affect children's psychological development, but also endanger children's physical health, according to the survey data released by the China Health Promotion and Education Association, the incidence of precocious puberty in children on the mainland is about 0.43%, and there are about 530,000 children in the country.
We can often see many reports that the cause of precocious puberty is attributed to fried chicken, soy milk, milk, etc., but in fact, the most important reason for children's precocious puberty is the parents' unawareness.
Why?
Rumors about precocious puberty
Precocious puberty is divided into two categories: true precocious puberty is called central precocious puberty, true precocious puberty is the early maturity of the internal and external reproductive systems, also known as complete precocious puberty, such a child's sexual characteristics appear early and have fertility, such is a disease, need to go to the hospital in time.
Pseudoprecocious puberty is called peripheral precocious puberty, that is, the development of secondary sexual characteristics is inconsistent with the pace of gonadal development, the testicles or ovaries themselves are not developed, but some secondary sexual characteristics appear early. The vast majority of children are pseudoprecocious.
Many people attribute pseudo-precocious puberty to fried chicken soy milk, and even very common animal foods that cause precocious puberty, typical sayings include contraceptive-fed eels and aquatic products, hormone-fed fast-growing chickens, fattening pigs, etc.
On the issue of eels feeding contraceptives or hormones, rumors have been circulating for many years, and later the people's network even made a special "verification" column to debunk the rumors, concluding that it is impossible to feed contraceptives or hormones, otherwise the eels will only die quickly. But one thing is true, eels are females as children and become males when they grow up, but this doesn't require any exogenous hormones.
And the fast-growing chicken is actually a white feather chicken, which is the result of good breeding and scientific feeding, "fattening" pigs may indeed have hormonal problems, but not sex hormones, but β receptor agonists, belongs to the adrenaline-like drugs, which is often said to be clenbuterol, and precocious puberty do not want to dry.
There is also a very classic bovine colostrum leading to precocious puberty, although the estrogen content in bovine colostrum is higher (about 5-10 times that of regular milk), but because they (estrone, estradiol and estramine, etc.) are mainly distributed in milk fat, the processing process of bovine colostrum health food includes the degreasing process, and the fat content in the defatted milk after defatting is usually less than 0.5%, and the degreasing process can greatly reduce the free estrogen content in the finished product. In addition, processing processes such as ultrafiltration and heating may cause the loss of estrogen in the milk. To date, existing studies have not provided conclusive evidence of the health hazards of hormone residues in meat and milk products.
The main cause of precocious puberty
The main cause of pseudo-precocious puberty is poor eating habits that cause excess energy and nutritional imbalance, so that children are overweight or obese, and too much fat accumulated in the human body will easily promote the formation of estrogen, resulting in precocious puberty. Fried chicken, soy milk and colostrum are originally high-calorie, high-fat, high-protein foods.
Many parents are worried about their children's lack of nutrition, too much to supplement their children with high-protein, high-fat food, and some parents are too doting on their children, children want to eat fried chicken burgers, they indulge their children to consume too much high-calorie food.
Every meal must be fried food, meals are big fish and meat, and too much intake of these three high (high fat, high calorie, high protein) food, it is easy to lead to excess energy and nutritional imbalance.
Scientist Wang Huizhen once surveyed 8750 children in Zhengzhou and found that obesity has a promoting effect on children's precocious puberty, increased fat or rapidly rising BMI can be used as a precursor to sexual precocious puberty, and the reason for the increase in the incidence of precocious puberty is related to the increase in childhood obesity rate, especially in girls, obesity will make girls' puberty development advance. Numerous studies abroad also support this argument, such as a Spanish study showing that adolescent initiation in boys is positively correlated with BMI.
But the scientific community has not yet shown that food and children's precocious puberty have a direct relationship, that is to say, food does not directly lead to children's precocious puberty, so many people say what fried chicken, hamburger, soy milk leads to precocious puberty, this is no scientific basis, if you have to say that the two are related, it can only be bad eating habits (long-term intake of high-fat, high-calorie food) leads to excess nutrition in the baby, causing obesity, which leads to precocious puberty.
In addition, many parents are worried that their children have not absorbed nutrients, to the child to eat supplements, even adult supplements, some so-called health products even "blue hat" (health food that obtains health care product approval, you can print the blue hat label of the health product approval mark on the outer packaging of the product), which will lead to abnormal hormone levels in children.
From this point of view, in fact, it is the parents who "destroy" the child. Parents do not cultivate their children's good living habits and let their children develop the habit of eating reasonably, which leads to precocious puberty due to excess energy. Parents should cultivate healthy eating habits of their children from an early age, pay attention to the reasonable combination of cereals, vegetables, meat, eggs and milk, and increase the amount of exercise, so that children's growth and development can be benign development.
How to know if a child is precocious
Precocious puberty is age-limited, generally girls before the age of 8, boys before the age of 9 years of secondary sexual characteristics development, such as breast development, menarche, pubic hair beard development, sudden growth of a man, etc., in order to be included in the age limit of precocious puberty diagnosis, once beyond this age, it is not precocious puberty.
There are two peak periods for children to grow taller, the first peak period is within 2 years of age; the second peak period is puberty, and precocious puberty is generally eight or nine years old, and children aged eight to nine suddenly grow taller in a short period of time, such as a month suddenly increased by 1 centimeter, then parents should pay attention.
In puberty, girls in the breast began to develop within 1 year, boys before the voice change, girls average 8 cm per year, boys 9 to 10 cm, and just when the same age of children jumped, precocious children because of early "overdraft" and stopped growing, can only watch other children grow tall, one by one surpassed themselves and helpless. If parents find that their child's height growth deviates greatly from the average, they should pay attention to whether there is precocious puberty or delayed development. In addition, parents should pay attention to the changes in their children's personality, and children will have uneasy emotions due to changes in their own bodies.
