Health care products have health care functions, but eating health care products indiscriminately will not only have no health care effect, but will also damage the health of the elderly. Not taking health care products as needed will lead to certain functional disorders of the body and other side effects. For example, taking too much of a single vitamin, and it is vitamin A that is not easily excreted from the body, may sometimes lead to poisoning. Taking too much of some Chinese herbal supplements can cause poisoning, liver damage and other consequences due to the medicinal properties. Some health products add a certain amount of hormones, and users must pay attention to the overall balance. Too many hormones will be very harmful to health. Health care products are not for the purpose of treatment, but are only used for disease prevention and health maintenance. They are suitable for specific groups of people, such as sub-healthy people, certain vitamin deficiencies, etc. Therefore, health products cannot be used as a substitute for daily diet, and the elderly should pay special attention to this. Therefore, it is recommended that the elderly take some calcium-supplementing medicines and health products. If they suffer from iron deficiency anemia, in addition to increasing the absorption of iron from food, they can also take some iron-containing health products. However, iron supplementation should be carried out under the guidance of a doctor, because iron is not easily excreted from the body, and excessive iron supplementation can lead to iron poisoning. Test your body first and then choose health care products. What should the elderly choose based on when choosing health care products? Although taking health supplements does not require a doctor’s prescription, anti-aging health supplements can generally be taken by the elderly. However, it is best to choose appropriate health products based on a comprehensive physical examination of the elderly and a comprehensive analysis. The elderly should have physical examinations in spring and autumn every year. It is best to consult a nutritionist before taking health care products. If you are worried about the lack of certain trace elements in the blood, go to the nutrition department of the hospital for a hair test or blood test. Based on the test results, you can see what is missing and how much is missing, and the doctor will give you a suitable supplement plan. After adjusting for a period of time, the elderly should be tested again. If the indicators are up to standard, no more supplements should be taken. Because further supplementation will cause other discomforts. Elderly people can take some health products. One is anti-aging health products, whose main function is to fight against free radicals. For example, vitamin C, vitamin E, lycopene, etc. The second is health care products that improve immunity and promote metabolic function. The third is health products that improve intestinal function, such as lactase and so on. He specifically reminded not to take a health product for too long, because health is about "balance." When choosing health care products, you should pay attention to the following six steps: 1. Recognize the attributes, that is, see whether you belong to the specific group of people listed in a certain health care product. 2. Find your own needs. 3. Understand the active ingredients (functional ingredients) in the product, and do not be distracted by the efficacy promotion in advertisements. For example, there are as many as forty or fifty kinds of sleep-adjusting health products such as melatonin on the market, with different names and different promotions, but their active ingredients are all melatonin. 4. Pay attention to the production unit and approval number to see if there is a "Jian" font. 5. Check whether there is a "suitable group of people" in the precautions on the product manual. If there is no such description, you can at least judge that this kind of health product is irregular. 6. Some health product descriptions also list “unsuitable groups”. Be sure to read and compare them carefully before purchasing.
