Most children like to eat ham sausage, and they are addicted to eating. Some parents go to the market to buy lots of ham sausage for their children. Children should stop eating ham sausage, and don't overeat it. First of all, eating ham sausage as a staple food for a long time can't meet all kinds of nutrients needed by children's growth and development. After eating ham sausage, children generally don't eat other meals, or eat very little. Obviously, children are growing physically and intellectually. In the production process of ham sausage, a certain amount of preservatives are added to prolong its shelf life. These chemical preservatives will not pose a threat to people when the quantity is small, and the factory has formulated its dosage in ham sausage accordingly, but eating them in large quantities for a long time is equivalent to ingesting high-content chemicals. After children enrich such chemicals to a certain extent, Low-iron hemoglobin in human blood may be destroyed by the substances generated by the reaction between such chemicals and meat, and lose the ability to transport oxygen, thus causing dizziness, headache, lethargy, nausea, vomiting and other symptoms in children, which will do great harm to the body. The production process and eating flavor of luncheon meat are similar to those of ham sausage, and it is also a favorite food for children. Therefore, parents should also be reminded here that children should not eat a lot of luncheon meat for a long time.
