Winter is the time when the kidney dominates, and the kidney dominates the storage, and Yuanyang is rooted in the kidney. Therefore, at this time, we should properly supplement diet and health care, nourish and store yang, tonify kidney and store essence, and promote the rise of yang in the body.

Chinese medicine suggests that at this time, it is advisable to eat more foods with cold-proof function to facilitate recuperation. Such as mutton, beef, chicken, turtle, pigeon, shrimp, quail, glutinous rice, chestnut, leek and so on. These foods are rich in protein and fat, and generate more calories, which can warm the middle and lower jiao, invigorate qi and generate blood, and have a good effect of keeping out the cold. You can also eat more ingredients that tonify the kidney. People with kidney-yang deficiency can eat more yam, Euryale ferox, black beans, walnuts, velvet antler, hippocampus, Eucommia ulmoides, Cistanche deserticola and so on. People with kidney yin deficiency can eat more sea cucumbers, sesame seeds, medlar, mulberry, Polygonum multiflorum Thunb, tremella and so on.

However, "tonic" should be scientific, and it is best to treat it according to syndrome differentiation under the guidance of professional doctors, and tonic should not be excessive.

At the same time, due to the increase in the intake of high-calorie ingredients, we should pay attention to eating more fresh fruits and vegetables, such as vegetables, potatoes, tofu, soybean milk, oranges and apples. To avoid vitamin deficiency, oral ulcer, dry tongue and lips, swollen gums or bleeding, constipation and other phenomena. In addition, white radish is also a good choice. After beginning of winter, the digestive function of human body is relatively enhanced, and it is easy to get angry if you eat too much. At this time, eating white radish has the functions of clearing away heat and resolving phlegm, resolving food stagnation and eliminating abdominal distension, so it is called "eating radish in winter".
