When it comes to dog days, what people think most is: dog days, what to eat? There is an old saying: "jiaozi lies on his head and pancakes roll eggs on his feet." . Eating jiaozi, pancakes and noodles in dog days not only means the joy of abundant food after harvesting wheat in summer, but also reminds people that their diet in summer should not be too fragmentary, and they should always comfort themselves and eat more foods rich in protein and B vitamins. Because of the high temperature and sweating in summer, a lot of protein amino acids will be lost, as well as a lot of B vitamins and minerals such as potassium and sodium. Eating noodles is more conducive to supplementing nutrition. When it comes to what to eat, there are four main points: sour and sweet, invigorating qi and removing fire, fresh and clean, and replenishing water for health. Ancient sour and sweet scholars thought that "summer dampness should be cleared up." In hot summer, people like cold drinks and drink plenty of water, so that moisture invades the human body, while external moisture enters the body, making water wet and invigorating the spleen, lifting the spleen and stomach, causing digestive dysfunction, stagnant water and loss of appetite. According to the viewpoint of TCM health preservation, dryness and dampness in summer are very unfavorable to spleen, so it is appropriate to eat more sweet and cold or sweet and cold in daily diet. And in summer, you return to your heart, but your heart likes cold and wants to eat sour, so you should eat more sour in summer. Such as pineapple and watermelon. Supplementing qi and removing fire in hot summer not only brings us physical discomfort, but also easily causes more and more people to get angry, which is manifested as emotional irritability, anxiety, excitability and insomnia. These symptoms are called "summer mood disorder" in medicine. Therefore, "removing fire" is also a compulsory course for summer food supplement. The best choice for summer food is bitter gourd, tomatoes and other cool fruits and vegetables. At the same time, milk is slightly cold, which can replenish water, nourish yin and reduce fever, and is also a good product for "dispelling fire". Dog meat and duck meat is the best way to make up for it in summer. Chinese medicine believes that the stomach is the foundation of the day after tomorrow. In summer, people often feel poor appetite and the function of the spleen and stomach is relatively slow. At this time, they might as well eat some fresh fruits and vegetables. The nutrients in fresh fruits and vegetables are generally half cellulose and half sugar, which can not only effectively supplement the necessary energy and water for human body, but also make people eat for a long time. Carrots, lemons and amaranth are the first choice. Eating more wild vegetables and fruits in season is of great benefit. But be careful not to eat cold or unclean food to avoid dysentery and diarrhea.
