Why is eating apple peels said to cause cancer?

　　In order to effectively control pests and diseases, various pesticides are still needed in agricultural production in various countries around the world. Many pesticides are insoluble in water but have a high affinity for waxes. The outermost layer on the surface of apples is a waxy layer, and pesticides are adsorbed in the wax, which can effectively protect the fruit from infection by pests, diseases, and bacteria.

　　Because fat-soluble pesticides have long-lasting effects and are not easily washed away by rain, many fruit farmers prefer to choose this type of pesticide. At the same time, such chemicals are generally not easy to enter the fruit, thus reducing the total amount of residues. So even though apple peels contain special nutrients, they may indeed contain more pesticides than the flesh.

　　It should be said that if pesticides are used strictly in accordance with the regulations of relevant national departments, even if there are trace amounts of pesticide residues, they will not harm the human body. healthy . However, in my country's agricultural production, excessive pesticide abuse or the use of substandard pesticides often occurs. Some misused and inferior pesticides may be carcinogenic.

　　Fat-soluble pesticides are adsorbed in wax and are difficult to remove even with detergent. Therefore, peeling and eating it is a safer option. Most fat-soluble pesticides have a strong medicinal smell, which can be identified by smelling them carefully. Among the fruits that can be eaten with their skins, apples and pears are the ones that people consume the most every day. Apples and pears are easy to peel. If you can smell the medicinal smell, of course you should peel them and eat them.
