First of all, old people should know that many advertisements for health care products often exaggerate their efficacy, and some even make false propaganda, which is a commercial behavior to attract consumers to buy. Here are some methods for reference:

Investigate the ingredients of health care products: you can first understand the ingredients and functions marked on the packaging of health care products and make a comparative analysis. Can let the elderly pay attention to the content and quantity in the ingredient list, whether there are side effects or adverse reactions, and so on.

Search experiments and research results: Search relevant health information confirmed by long-term rigorous scientific research, share experimental data and reports with the elderly, and let the elderly know the real role of health care products. These data can be compared with the advertising language of health care products, so that the elderly can understand the differences of advertising language.

Popular science knowledge: educate the elderly to realize the importance of a balanced diet, moderate exercise and regular doctor visits, and introduce the necessary trace elements in depth. In this way, they can pay more attention to their health in their daily lives, and achieve the purpose of preventing diseases and delaying aging.

Remind the elderly to protect their information security: remind the elderly to guard against fraudulent means such as telemarketing and mail fraud. Tell them not to trust phone calls or emails of unknown origin, and be careful to judge whether they are deceived by criminals.

These methods may not completely convince the elderly that health care products are scams, but it is hoped that by strengthening scientific knowledge and anti-fraud awareness, the elderly will reduce their risks, pay more attention to their own health, and effectively reduce the possibility of being misled by health care products advertisements.
