Soup is an advanced nutritional supplement, but after a night, the nutritional components will be reduced and harmful components will be produced. Because both the tremella cultivated indoors and the tremella cultivated in the wild of basswood contain more nitrate, if cooked for a long time, the nitrate will be reduced to nitrite under the decomposition of bacteria.
When people drink this soup, nitrous acid naturally enters the blood circulation. Red blood cells in the blood contain hemoglobin, which can carry a lot of oxygen for the body's needs. Nitrite, on the other hand, has the opposite effect, oxidizing normal hemoglobin in human body into methemoglobin, losing its oxygen-carrying ability, leading to the loss of normal hematopoietic function in human body.
