Traditional Chinese medicine stresses deficiency of yin and yang, cold, hot and cold, and the taste of food is sweet, sour, salty and bitter. It has always been a precious tradition of traditional Chinese medicine and a dietotherapy feature of medicated diet that "bamboo breaks bamboo to make up for it, pollution is controlled by pollution, sound is the same, and god is the same". When drugs and food are properly matched, they often cooperate with the operation to increase the curative effect.

For example, Chinese medicine and western medicine are sometimes difficult to treat and use drugs for yin deficiency and damp heat. But ducks in food can treat these symptoms at the same time. They can nourish yin, not love dampness, and benefit dampness without hurting yin. With symptomatic drugs, it is easier to receive satisfactory effects such as nourishing yin, clearing heat and eliminating dampness.

Moreover, the theory of traditional Chinese medicine emphasizes that the changes of the four seasons and five seasons are closely related to the five internal organs of the human body, so it is beneficial and harmless to choose supplements according to the seasons and the appropriate supplements according to the "four seasons and five supplements".

For example, everything recovers in spring, and the liver corresponds to it in the five internal organs of the human body. At this time, it is appropriate to "strengthen and replenish deficiency" and choose Shouwugan tablets and Chijian Fengguan.

The climate in summer is hot, the heart corresponds to summer, but the human body is cool in spring. At this time, it is appropriate to "clean up" and choose rock sugar sea cucumber and nectar.

Going to Qiu Lai in summer is characterized by dryness (long summer and heavy dampness), and the lungs correspond to autumn. At this time, you only need to "make up" and choose Cordyceps duck, Mint White Festival, Snow Stewed Chicken and so on.

It is freezing in winter, and the human body functions turn to convergence, and the kidneys in the five internal organs correspond to winter. At this time, it is suitable for "nourishing", and Shen Lu Chang Gui Tang, debt repayment beef soup, trilateral Yang Yang soup and so on are selected.

In addition, there is a mild medicated diet, which can be used at any time regardless of season, such as: white pigeon with yam, glutinous rice balls with ginseng and chicken oil, pearl crucian carp, Qingyuan white jiaozi, beef with fragrant sand, Poria stuffed bun, Four Treasures of the Study quail, Baoyuan chicken, shark's fin with dragon, nutritious wonton, Shoubi Nanshan, ginseng spinach jiaozi and so on.

When middle-aged and elderly people take medicated diet food, they should also pay special attention to the temperature, heat, maturity and softness of the medicated diet. The amount should be small and the taste should be light. They should eat less cold, sticky, hard, heavy and thick food to protect their spleen and stomach, which is the source of biochemistry and the foundation of the day after tomorrow. We should also pay attention to the taboo of taking medicine, so that medicated diet can give full play to its role and contribute to the health of middle-aged and elderly people.

Can people who are generally not aging and healthy take supplements? We think it is also beneficial for these people to choose supplements properly in peacetime. Because human cells are metabolizing at any time, we should constantly supplement things that are beneficial to the human body. Fruits, vegetables, eggs, fish, etc. It is not only daily food, but also a tonic. In order to maintain the healthy spirit and vitality of human body, resist external evils, prevent diseases and delay aging, we should also choose light and nourishing medicinal diets such as Yulan chicken, dried hawthorn, sea cucumber, cardamom steamed bread, Fritillaria and Sydney, oolong wings, Achyranthes bidentata, golden shrimp and strong eel.
