What is better to eat on the solstice in winter?

In winter, the climate is cold, with yin flourishing and yang declining. Under the influence of cold temperature, the physiological function and appetite of human body will change. Therefore, it is very necessary to adjust the diet reasonably, ensure the sufficiency of essential nutrients, improve the cold tolerance and immune function of the elderly, and make them spend the winter safely and smoothly.

First of all, we must ensure the supply of heat energy. The cold climate in winter affects the endocrine system of human body, which increases the secretion of thyroxine and adrenaline, thus promoting and accelerating the decomposition of protein, fat and carbohydrate, increasing the body's cold-proof ability, thus causing excessive loss of heat. Therefore, nutrition in winter should be based on increasing heat energy, and foods rich in carbohydrates and fats can be properly ingested. For the elderly, the intake of fat should not be too much, so as not to induce other diseases of the elderly, but enough protein should be taken, because the decomposition of protein is enhanced, and the human body is prone to negative nitrogen balance. The supply of protein should be 15 ~ 17% of the total calories, and the supply of protein should be mainly high-quality protein, such as lean meat, eggs, fish, milk, beans and their products. Protein contained in these foods is not only easy for human body to digest and absorb, but also rich in essential amino acids with high nutritional value, which can increase human body's cold resistance and disease resistance.

Winter is the off-season of vegetables, and the number of vegetables is small and the varieties are monotonous, especially in northern China. Therefore, often after a winter, the human body appears vitamin deficiency, such as vitamin C deficiency, which causes many elderly people to have symptoms such as oral ulcer, swelling and pain of root, bleeding and constipation. Its prevention and control method should first expand the food source, and the green leafy vegetables are relatively reduced in winter, so you can eat some potatoes, such as sweet potatoes and potatoes. Are rich in vitamin C and vitamin B, especially lack of vitamin A, and red sweet potatoes also contain more carotene. Eating more potatoes can not only supplement vitamins, but also clear away heat and eliminate plague. In addition to Chinese cabbage, cabbage, radish heart, white radish, carrot, bean sprouts, mung bean sprouts, rape and so on. It should also be selected in the main course listed in winter. These vegetables are rich in vitamins. As long as the varieties are changed frequently and matched reasonably, the vitamin demand of the human body can still be supplemented. The cold in winter will also affect the nutritional metabolism of the human body and increase the consumption of various nutrients to varying degrees. Due to the influence of digestion, absorption and metabolism in the body, the elderly often lack potassium, calcium, sodium, iron and other elements. In addition, the inorganic salts discharged with urine in winter increase, which should be supplemented in time. You can eat more foods rich in calcium, iron, sodium and potassium, such as shrimp, shrimp skin, sesame paste, pork liver and bananas. If there is low sodium, it tastes slightly salty when cooking, so you can make it up.
