This kind of thing is really difficult. The main reason why the elderly are superstitious about health care products is lack of knowledge and rational thinking. They hope their health will get better, and salesmen brainwash them too much. In order to prove that health care products don't work, we should also do anti-brainwashing work to brainwash the elderly.

One is to talk repeatedly about the knowledge of physical health, how to digest food, what substances people need for their growth, and what will happen to the human body without any substances, so that the elderly can see more about the road to health and the plan of keeping a healthy house. Keep talking and nagging.

The second is to prove that human growth does not need health care products with rational thinking of reasoning and analogy. Let's take a look at the animal world first. Animals don't eat ginseng and donkey-hide gelatin, but they all grow fat and strong. How did you grow up alone? Have you been eating health care products for a long time since you were a child? Repeatedly stressed that people can grow normally as long as they eat normal food. Be sure to say it again and again, and take pains to say it.

The third is the specific analysis of health care products. If the ingredients are food ingredients, such as protein powder, eggs, milk and lean meat are much stronger than protein powder. If it is Ejiao, it is called skin jelly, which is similar to pigskin. If it is a pharmaceutical ingredient, it means that normal people do not need non-food to enter the body. The human body has the function of rejection, and it may also induce cancer if it is not done well.

Fourthly, it is necessary to say that life aging is a natural law and irreversible. For example, osteoporosis, health promoters talk about the importance of calcium supplementation. Bone loss in the elderly is also an irreversible process. If you think about it carefully, we can grow from a doll to an old age as long as we eat normal food, which shows that there is no shortage of calcium. Calcium supplementation for the elderly is purely comfort.

The fifth is to reduce the loneliness of the elderly. Advocate a healthy and happy life for the elderly, dance square dance, join a choir, play Tai Ji Chuan, brag and play chess in the street, occasionally drink some wine, read the Analects of Confucius and learn some Chinese medicine. No health activities, no eggs, no free banquets. Remember the old adage, catch a big fish with a long line, and no pie will fall from the sky.
