Drug distribution. Out-of-season fruits are not necessarily caused by drug processing. Don't worry about the out-of-season fruits cultivated by pollution-free foods, but the fruits ripened by illegal drugs will have problems.
People use the production environment conditions to grow conventional anti-season fruits under certain temperature, humidity and soil conditions. For example, tomatoes are normally planted in spring and early summer, but if they are cultivated in greenhouses, they can be eaten in spring or even winter. The normal production period of grapes is in summer, and grapes can also be produced in spring through greenhouse planting. These out-of-season fruits are also rich in nutrition and sweetness. If it is anti-season fruits and vegetables cultivated by pollution-free food, it can be guaranteed technically, and the quality is not much different from that of normal season products.
Ripening fruit is a problem fruit that is ripened and kept fresh by chemicals. Some are out of season; Some are not far from ripening, and some fruit farmers "medicate" the fruit to ripen in order to sell it for a good price a few days in advance. At present, the fruits being sold in our city, such as strawberries, watermelons, apples and pineapples, are mainly transported to our city from other provinces. If you count the ripening time and long-distance transportation time, these fruits are often picked when they are immature and "drugged" for preservation.
"At present, not only strawberries, but also some other fruits and vegetables appear in front of people before maturity. Some citizens who are eager to adopt early adopters often pay high prices. Some mercenary vendors seize the psychology of consumers and use ripening agents to make immature fruits precocious. Even in the fruit harvest season, some fruit farmers will sell the fruit for a good price a few days in advance, and they will also' medicate' the fruit to ripen in advance. This operation is very hidden. " A manager of Caiyuanba Fruit Wholesale Market told the reporter.
Fruits growing in the wild should follow their natural growth laws. What fruits to eat in what season and fruits ripened with hormone chemicals are very harmful to children's growth and development.
Out-of-season food can easily cause precocious puberty in children.
Eating a lot can lead to precocious puberty in children, but people pay far less attention to it.
1. Edible nourishing food: including Cordyceps sinensis, Ginseng, dried longan, dried litchi, Astragalus, Adenophora, etc. Chinese medicine points out that the more medicated diet is supplemented, the easier it is to change the normal endocrine environment of children, resulting in unbalanced physical and mental development.
2. Poultry meat, especially poultry neck meat
At present, most poultry sold in the market are fed with feed mixed with rapid growth agents, and the residue of "ripening agent" in poultry meat is mainly concentrated in the glands of the head and neck of poultry. Therefore, eating the neck of chickens, ducks and geese has become a high-risk behavior of "promoting precocity".
3. Off-season vegetables and fruits
Strawberries, grapes, watermelons, tomatoes, etc. Pears, apples, oranges and peaches, which are listed in advance in winter and late spring, are almost out of season or mature in advance with the help of "ripening agents", so it is necessary to avoid giving them to children.
Many out-of-season fruits are ripened and kept fresh with some chemicals, which not only has low nutritional value, but also brings great harm to the body. Children should eat them carefully. Experts especially remind that out-of-season fruits will make children precocious.
Out-of-season fruit itself is harmless, but some illegal fruit farmers overuse plant growth regulators, that is, hormones, in order to increase production. These hormones can promote fruit development, growth and early maturity, and the yield can be increased by about 20% after using hormones. Regular consumption of out-of-season fruits will lead to precocious puberty such as early menarche in girls, while the sexual characteristics of boys are not obvious.
4. Fried food
Especially fried chicken, French fries and potato chips, excessive calories will be converted into excess fat in children, causing endocrine disorders and leading to precocious puberty; Moreover, after repeated heating and use, high temperature makes it oxidized and denatured, which is also one of the reasons for "precocious puberty". Children who patronize foreign fast food more than twice a week and often eat fried puffed food are more prone to precocious puberty than ordinary children. Five times.
5, some children's oral liquid
Many tonics and oral liquids advertised as "growing taller and stronger" for children's market contain hormone components. These hormones make children grow taller and stronger than their peers at the age of five or six, and their bone age has reached 8 years old or 10 years old. When the child enters the normal development stage, it won't grow any longer.
