Will drinking milk every day lead to precocious puberty? take stock of the four major hazards of precocious puberty

Children's precocious puberty has become an issue of great concern to parents nowadays, and some media say that "precocious puberty is eaten." Recently, it has also been reported that drinking milk will lead to precocious puberty, and is it caused by milk hormones or artificial addition? Opinions are widely divided. Speaking of today's milk, many people will blurt out, "Today's milk is driven by hormones, the taste and nutrition are not good, and it will lead to precocious puberty in children." . Is this true?

Physicians and pediatricians have repeatedly mentioned that more and more girls who go to their clinics have developed breasts and pubic hair by the age of six or seven. The primary school teacher also mentioned that from the comparison of the class of students, the physical development of the boys in the class did not change much, but the female physiological characteristics of girls appeared earlier and earlier. Is this directly related to drinking milk every day?

What is the difference between endogenous hormones and exogenous hormones in milk

There are several endogenous hormones in milk, but their contents are very low. At present, no effect has been found on sexual development, reproductive function and endocrine function of human body. According to the structure, milk contains steroid hormones and peptide hormones; according to the source, the hormones in milk are divided into two categories: endogenous and exogenous hormones. The so-called endogenous hormones come from the hormone components in the blood of dairy cows, which can be transferred to the breast, pass through the blood-breast barrier, secrete through the milk, and enter the milk, and some of these hormones can also be synthesized and secreted into the milk. Therefore, the content of some types of hormone milk is higher than that of cow blood. The endogenous hormones in milk are mainly divided into gonadal hormones (estrogen, progesterone, androgen), adrenocorticoid (glucocorticoid), pituitary hormone (prolactin, growth hormone), hypothalamic pituitary stimulating hormone (growth hormone releasing hormone) and other protein-related hormones such as parathyroid hormone, calcitonin, insulin and so on. The exogenous hormones in milk mainly come from cow therapeutic hormones such as diethylstilbestrol, of course, do not rule out the addition of exogenous hormones in cow feed in order to increase milk production. Generally speaking, countries around the world have a certain limit on hormones, especially exogenous hormones in food, or are not allowed to be detected.

Will children drink milk lead to precocious puberty?

As to whether the hormones in milk are related to precocious puberty, the Ministry of Health held a press conference on August 15, 2010, announcing that no prohibited exogenous sex hormones such as diethylstilbestrol and medroxyprogesterone acetate were detected in milk. the detected values of endogenous estrogen and progesterone are in line with the content range reported in the literature at home and abroad. The level of estradiol in milk is similar to or lower than that in human milk, and generally lower than that in bovine blood; there is no significant difference between estriol and human milk, but generally lower than that in bovine blood; prolactin in milk is higher than that in human milk and significantly higher than that in bovine blood. According to the current research evidence, there is no causal relationship between eating milk and milk powder and precocious puberty.

And further research found that there was no correlation between the two. Many scientists have noticed that if a girl develops too early, it is usually caused by obesity rather than milk. Girls who develop earlier tend to have a higher body mass index, which sometimes gives the false impression that they already have breast tissue. Considering that while conducting developmental research, the number of obese people across the country is also increasing, it is too early to come to the conclusion that the development is ahead of schedule. Although breeders give cows recombinant bovine growth hormone, it is not clear whether it will enter the milk. For this hormone to work, it must be injected, not fed, so if it does appear in milk, it may have little effect.

Food that can easily lead to precocious puberty in children

The precocious puberty of children has become an issue of great concern to parents nowadays. Some media say that "precocious puberty is eaten" and list the high-risk diets that can lead to precocious puberty. such as foreign fast food, out-of-season fruits, nourishing soup, poultry with ripening agents best ass , beans, and so on, among these foods, we should be on guard against chicken and duck heads.

The residue of "ripening agent" in poultry meat is mainly concentrated in the head and neck of poultry, which can easily cause precocious puberty in children cock cages , so children should eat less chicken head and duck head. A large number of intake of Cordyceps sinensis, ginseng, dried longan, dried litchi, astragalus, sand ginseng and other nourishing traditional Chinese medicine, it is indeed easy to cause precocious puberty in children, so parents should not supplement their children too much.

As for out-of-season fruits and vegetables, it does not promote precocious puberty. Under the action of appropriate temperature, humidity and organic fertilizer, out-of-season vegetables and fruits can grow well without ripening agents. So out-of-season fruit can still be eaten by children. The content of isoflavones in legumes is very low, and daily consumption of legumes will not cause precocious puberty.

Guard against the four dangers of preventing precocious puberty

Specifically penis pumps to treat ed , precocious puberty is an endocrine disease. So far, more than 90% of the cases of precocious puberty clinically received in most hospitals are girls. Of course, this does not mean that boys have a gender advantage in the disease. On the contrary, among the only 10% of precocious boys, most of them are caused by tumors and need to be paid more attention by their parents. Of course, there are many aspects of the harm of precocious puberty in children, and for children themselves strap on dildo , there are mainly the following four aspects:

1. It is easy to cause psychological disorders to children.

Although the sexual characteristics of precocious children develop in advance, the level of psychological and intellectual development is still the actual age level, and premature sexual characteristics and reproductive organ development will lead to psychological disorders in immature children. in particular, seeing that they are different from those around them can easily lead to children's inferiority complex, which is likely to leave sequelae in their adulthood.

2. distract the children and affect their reading and study.

It should be said that the emergence of sexual characteristics and the development of reproductive organs will certainly distract children, especially girls, early menstruation will often make them feel uneasy, shy and nervous. At the same time, the girl's physical development is too early, unable to deal with the impact of menstruation on life, coupled with the imbalance of physical and psychological development, but also brought a lot of inconvenience to life, which is bound to affect children's reading and learning.

3. affect the height of the children, resulting in their final height shorter than that of their peers.

Precocious children are often accompanied by accelerated bone growth, making them look taller than children of the same age. In fact, this is only a temporary phenomenon, due to the early release of sex hormones, the epiphyseal closure will be greatly advanced, and the growth period will be shortened accordingly, that is, the long bone diaphysis and epiphysis will close ahead of time and stop growing. In general, the average length of girls after menarche and boys within 3 years after the first spermatorrhea is only about 5 centimeters, so the final height of precocious children is shorter than that of their peers.

4. It can cause systemic endocrine disorder in children.

We know that precocious puberty itself is an endocrine disease, but there are individual differences in the degree of endocrine disorders in children, that is, there are priorities. Children with mild symptoms mainly show imbalance of sex hormone levels, while children with severe symptoms will lead to systemic endocrine disorders, such as hyperadrenocortical dysfunction will cause systemic hirsutism, on the contrary, children with low adrenocortical function are characterized by hair loss, dryness, and even accompanied by loss of pubic hair and axillary hair. In patients with hyperthyroidism, the hair can be seen soft or prematurely gray, while children with the same hypofunction will have symptoms of reduced hair in the growing period and increased hair in the retrogressive period. This is only the external manifestation of endocrine disorders in the hair, there are many systemic symptoms, can not be described in detail.

In short, this is also a major harm of precocious puberty to children themselves.
