1, excessive animal food Modern families are mostly only child, so with the improvement of living conditions, parents often hope that their children can now eat better, especially the grandparents, afraid that children do not eat well enough. But the intake of excessive animal foods, not only easy to cause obesity in children, often also ingested too much additives in animal feed. Nowadays, the vast majority of poultry sold in the market is fed with feed mixed with fast growth agents, as is often the case with pigs, cattle and lamb. This is probably the most common reason for the current increase in precocious puberty year by year. At the same time, with the aggravation of environmental pollution, pollutants may also enter the animal body, and the pollutants in the animal body are more likely to be deposited in the bone marrow, too much bone broth, not only can not make up calcium, but also may cause lead poisoning and precocious puberty. Human fat cells can also secrete a small amount of estrogen. Obese children, precocious sexual maturity is significantly higher than normal children. 2, anti-seasonal vegetables and fruits winter strawberries, grapes, watermelon, tomatoes, etc., early listing of pears, apples, oranges and peaches in late spring, almost all in the “ripening agent” to help anti-seasonal or early ripening, must be avoided for young children to eat. Excessively bright fruits, often induced by ripening agents, should also be avoided. Fresh lychee and other foods, because they contain certain substances similar to human estrogen, excessive consumption may also cause premature sexual maturity. 3, the big tonic food can be used in the medicine of the big tonic food including cordyceps, ginseng, dried cinnamon, dried lychee, astragalus, sage, etc.. According to Chinese medicine, the more tonic the food is, the easier it is to change the normal endocrine environment of the child, causing an imbalance in physical and mental development. Other things such as: silkworm pupae, chicken embryo, placenta, royal jelly, colostrum, pollen preparation nutritional supplements often contain high sex hormones, but also in the induced precocious puberty common causes. 4, fried foods, especially fried chicken, French fries and potato chips, excessive heat will be transformed into excess fat in children’s bodies, triggering endocrine disruption, leading to precocious puberty; and, after repeated heating of cooking oil, high temperature makes its oxidation denaturation, is also one of the causes of “precocious puberty”. The children who patronize foreign fast food more than twice a week and often eat fried puffed food, the possibility of “precocious puberty” is 2.5 times that of ordinary children. 5, some children’s oral liquids for children’s market, many of the supplements and oral liquids labeled “grow taller and stronger or increase appetite”, a significant portion contains hormonal ingredients. These hormones make children grow taller and stronger than children of the same age when they are five or six years old, and their bone age may have reached 8 or 10 years old. And when the child enters the normal development stage, but do not see the growth. There are also some health products (national regulations, health products are not allowed to promote any therapeutic effect), such as what protein powder, unless suffering from some special diseases, normal children simply do not need to use, now children, protein intake is often too much, and those supplemental trace elements of drugs or health products, can not exclude the possibility of precocious puberty. Trace elements are never more than necessary! 6, other factors Of course, in addition to food, supplements, health care products, there are some possible causes of precocious puberty, such as: excessive light is one of the important causes of precocious puberty in children, especially prolonged light at night will affect the normal work of the pineal gland, an endocrine organ in the brain, which may lead to the early secretion of gonadotropins, thus leading to precocious puberty. The extensive use of cosmetics, the proliferation of bad information (including text information, media information, network information, cell phone information, language information, etc.), environmental pollution, and the excessive use of chlorine-containing pesticides are also important causes of increased precocious puberty. Some of them are also caused by misuse of birth control pills. In short, from the above reasons, it seems difficult to find safe food. In recent years there has been a downward trend in domestic food safety, but attention should not be excessive, normal nutrition, a balanced diet is still very important, there is no absolute safety in the world! Everything has its two sides.
