Frost, as the last solar term of autumn, is a transitional solar term from autumn to winter, often resulting in a sudden drop in temperature due to the invasion of cold air. According to the "Explanation of the Seventy Two Seasons of the Moon Order", "In the middle of September, the air is calm and condensed, and the dew forms frost." Whenever frost falls, the Yellow River Basin in China generally experiences the first frost, while the southern regions enter the busy season of autumn harvest and autumn planting. How to eat during the season of 'frost'? After the frost has fallen, it is a good time to replenish. People often say that "it is better to replenish the frost than to replenish the winter". Liao Xixun, the attending physician and medical doctor of the Department of Preventive Medicine at Guangdong Qifu Hospital, reminds that after frost falls, it is advisable to nourish and avoid dissipation in dietary health, and to prevent the damage of autumn dryness to lung qi, laying a foundation for winter health. In daily diet therapy, you can choose some foods that have the effects of promoting fluid production, nourishing dryness, clearing heat and phlegm, relieving cough and asthma, and tonifying the lungs and kidneys, such as beef, rabbit meat, duck meat, radish, olives, onions, mustard, ginkgo, persimmons, dates, pears, apples, and so on. Traditional Chinese medicine emphasizes eating according to the season. "In spring, eat flowers, and in autumn, eat fruits." Foods such as sweet potatoes, yams, lotus roots, and water chestnuts are also suitable for eating during frost seasons. But it should be noted that seasonal food in autumn often tends to be cold and cool, which can easily damage the yang qi of the spleen and stomach. During the cooking process, seasonings such as scallions, ginger, and garlic can be added in moderation to complement their coolness and achieve a balanced state. Cold foods such as sea fish, shrimp, and various cold drinks should be eaten less to avoid damaging the lungs and causing diseases.
