In recent years, the market of health care products has developed extremely rapidly, which makes more and more elderly people addicted to buying various health care products. For some illegal biotechnology companies, they often take advantage of the elderly's pursuit of health and lack of medical knowledge to deceive the elderly through the gap between false propaganda and actual products. In this case, how should the old people see through the liar? This paper will analyze from the aspects of science, evidence and rationality, and explain how to prove to the elderly that some health care products are deceptive.

First, the most basic thing is to find the certification report of an authoritative organization.

When the elderly buy health care products, the first thing to look at is whether the health care products have been certified by relevant national institutions, such as the certification of the US Food and Drug Administration. According to relevant laws and regulations, health care products entering the domestic market must undergo relevant quality monitoring and be approved before they can be sold. These health care products are usually marked with numbers on the packaging, which is convenient for the elderly to inquire whether the health care products have been certified. If this health care product is not certified by the national regulatory authorities, it cannot be proved that it has the efficacy of preventing diseases, relieving symptoms, and maintaining health, nor can it be proved that it is safe.

Second, try to avoid only listening to the sales staff's propaganda.

Many biotechnology companies hire salesmen to promote their products, but this kind of publicity often falsely exaggerates the efficacy and effect of the products. In view of this situation, no matter how glamorous the propaganda language is, the elderly must keep a clear head and don't easily believe its exaggerated effect. You should know the actual effect of this health care product from people with relevant professional knowledge, or through the internet or newspapers to avoid being cheated.

Third, look at the label of commodity packaging.

For some fake and shoddy health care products, some words such as "honor award" are usually marked on their packaging. Especially online shopping, the elderly should pay more attention to whether the packaging of health care products is consistent with normal products. In addition, instructions, production date, production license number, etc. It is the standard to judge the quality of health care products. Old people should check carefully when buying them to avoid being deceived.

Fourth, pay attention to the physical condition of the elderly themselves.

The physical function of the elderly is generally worse than that of young people, so when purchasing health care products, you can also follow the doctor's advice and buy health care products that suit you and reduce the risk. In addition, the old people should follow the principle of honesty and trustworthiness, and don't buy fake and shoddy health care products for cheap prices.

In short, the elderly need to keep a cool head and comprehensively judge the relevant information in order to avoid being cheated. A correct view of health is very important. We need to cherish our health, eat reasonably, pay attention to exercise and protect our health to the maximum extent. As for how to prove to the elderly that some health care products are deceptive, it is not only the responsibility to inherit the scientific spirit, but also an important task to protect public interests and people's health.
