1. Understand diseases and popularize health knowledge. Birth, aging, illness and death are the inevitable process of life, and the elderly should learn to keep a positive attitude in the face of diseases; Combined with the common diseases of the elderly, diet suggestions and health care knowledge are given.

2. Correct understanding of health care products. Health products do not have the efficacy of preventing and treating diseases; Health products should be used rationally, not as much as possible. Community health service centers and family contracted doctors are in close contact with the elderly, helping them to choose health care products reasonably and giving them professional help and guidance.

3. Popularize the purchase channels of regular health care products. To buy health care products, we should obtain sales bills through formal channels and check whether the bills are consistent with the sales behavior; Be wary of all kinds of illegal marketing, such as exaggerating the promotion that health food can "cure diseases".
