Dr. Zhang Qingjun studied medicine with his elders since childhood, and has been a doctor for 57 years. Because he knows how to keep in good health, he looks flushed, speaks enthusiastically and thinks quickly. "Summer diet should be light and warm. In hot summer, the best choice is to drink porridge, such as eight-treasure porridge and mung bean porridge, which can not only make us feel full, but also achieve the functions of clearing away heat and relieving summer heat, tonifying kidney and reducing swelling. Due to the hot weather in summer, it is necessary to supplement enough nutrition and eat more meat, fruits, fresh vegetables, cereals and beans. In particular, eat more foods that clear away heat and damp, such as mung beans, tomatoes, bitter gourd and watermelon. " Zhang Qingjun said, eat more spicy food in summer, because spicy food can effectively stimulate the mouth and stomach, speed up blood circulation, lower body temperature and prevent heatstroke. In addition, many people have bad appetites in summer, so we should develop the habit of eating less and eating more meals, because only in this way can we meet the body's nutritional needs.
