When children are told not to eat junk food, they should not be told with a strict attitude, otherwise they will have a strong rebellious attitude, and instead they will eat more snacks. Therefore, parents should persuade their children to quit snacks, carefully and gently tell them the dangers of eating too much junk food, search some cases on the Internet, and tell them the true stories of eating junk food and hurting their health, so that they will have a certain fear of junk food.
In addition, if you can't make your child obey and reduce the consumption of junk food at one time, then make a plan for your child to reduce the consumption of junk food, and give him a limited amount every day so that the child can reduce the consumption step by step. This also prevents children from becoming more addicted because they suddenly quit snacks. Let him accept the plan and tell him that this plan is made for his better growth. Let him understand his parents' painstaking efforts, eat more healthy food, and make up for the harm of junk food with healthy food.
