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.
