1, avoid tonic if you have no disease. If you are not sick, you will not only increase your expenses, but also harm yourself. If you take glucose for a long time, it will cause obesity, increase blood cholesterol and easily induce cardiovascular diseases. Therefore, tonic must be based on your own physical condition, and "what is missing" can get twice the result with half the effort.

2. The more you avoid, the better. Eating too many supplements is harmful. It is unscientific to think that "take more tonics, treat diseases and strengthen the body without diseases". If you take too much ginseng tonic, it will cause bloating and you don't want to drink it; Taking too much vitamin C can cause nausea, vomiting and diarrhea.

3, avoid taking medicine. It is unscientific to value medicine over food. I don't know that many foods are also therapeutic drugs.

4, avoid the more expensive, the more you make up. "things are rare." Noble traditional foods such as bird's nest and shark's fin have no peculiar dietotherapy function, while very common foods such as sweet potatoes and onions have dietotherapy value worthy of attention. In addition, all dietotherapy has certain objects and indications, so medicinal diet should be determined according to needs, and it can't be graded by nobility.

5, avoid confusing the real with the fake. The treatment principle of traditional Chinese medicine is to replenish deficiency. It does not mean that patients with asthenia should not use tonics. Deficiency is divided into yin deficiency, yang deficiency, qi deficiency and blood deficiency. Only the right medicine can make up the body, otherwise it will be counterproductive and hurt the body.

6. Avoid all meat. Animal food is undoubtedly a good tonic. It is not only nutritious, but also delicious. However, meat is not easy to digest and absorb. If you eat too much for a long time, you will often be overwhelmed by the elderly whose gastrointestinal function has declined. Some "by-products" in the process of meat digestion, such as excessive lipids and sugars, are often the causes of common diseases and frequently-occurring diseases in the elderly, such as cardiovascular and cerebrovascular diseases and cancer.

7. Avoid paying more attention to "in" than "out". With the improvement of people's living standards, many families have meat and fish every day, and the food is greasy. The acidic toxic substances produced by the metabolism of these foods need to be discharged in time, and the accelerated pace of life makes many people have irregular defecation and even constipation. Therefore, waste in human body should be eliminated in time to reduce the retention and absorption of "enterotoxin".

8. Avoid constant "compensation". Some people like to take some tonic according to their own tastes, and then they have changed from being unchanged for many years to "partial eclipse" and "overeating", which is not good for their health. Because drugs and food not only have health care and therapeutic effects, but also have certain side effects, long-term use will affect the nutritional balance in the body.
