As we all know, Laoguang people love to make soup, and they are also the best at making soup. The third season, China on the Tip of the Tongue, also tells the story of the medicinal diet that Cantonese people pay attention to when making soup. Recently, however, a professor from Fudan University said in Weibo that Guangdong has become a high incidence area of kidney disease, because Cantonese people like to put Chinese herbal medicines in soup to remove moisture. What? Can you drink kidney disease after drinking soup? They expressed their dissatisfaction with old Ren Guang, who "would rather eat rice without meat than soup".

So is medicated diet a tonic or a pseudoscience? According to statistics, the incidence of chronic kidney disease in Guangdong is 12. 1%, ranking the top three in China, which is significantly higher than the national average. Is it related to making soup? According to epidemiological survey data and national registration data, the incidence of chronic kidney disease in China is about 10%, which means that there are about 654.38+200 million CKD patients.

In Guangdong, the incidence of chronic kidney disease in the province is 12. 1%, which is significantly higher than the national average, and the number of patients with chronic renal failure receiving hemodialysis ranks among the top three in the country. According to experts, too long soup cooking time is related to kidney disease. For example, Cantonese people pay attention to "three boiling and four stewing", that is, three hours to cook soup and four hours to stew soup. But if the stew lasts too long, the purine content in the soup is high. According to experts, the incidence of nephropathy is higher than the national average, which is really related to soup making, but it has little to do with medicated diet. Zhang Qiulin, director of the Department of Nephrology, Guangdong Second Hospital of Traditional Chinese Medicine, said in an interview with local media that Guangdong people pay attention to "three stews and four stews", that is, three hours of stewing and four hours of stewing, resulting in a very high content of purine in soup. At the same time, because it is rich in protein, it aggravates the filtration of glomeruli and the reabsorption of renal tubules, thus increasing the burden on kidneys.

In Zhang Qiulin's view, with the increase of age, the glomerular filtration rate will gradually decrease. Therefore, drinking soup for the elderly is more harmful to the kidneys. Old people should not excessively pursue the practice of drinking soup to replenish their bodies. In addition to the old fire soup, another Guangdong housekeeping skill-herbal tea is also the culprit. Zhang Qiulin pointed out that some herbal teas may contain traditional Chinese medicines such as cinnabar lotus, and long-term drinking will aggravate the damage to the kidneys; On the other hand, if you have nothing to do, you will drink herbal tea, which will hurt your qi, yin and kidney. In addition, the old people drink too much Lao Huo Tang, which is more harmful to the kidneys, because Lao Huo Tang is mainly made of chicken, duck and pig bones and is rich in protein. Protein's metabolism is filtered by glomeruli and reabsorbed by renal tubules, thus increasing the burden on the kidneys. So the best way to make chicken soup is to boil soup in casserole for 60 minutes.
