First of all, generally speaking, tremella soup cannot be drunk overnight, and it is not recommended to eat tremella in a braised beaker for one night. For example, white fungus cooked at night can be eaten the next morning. But if you put it from morning till the next morning, it is not recommended.
Because when we cook tremella soup, if it is stored for too long, nitrate will be reduced to nitrite under the decomposition of bacteria. When we drink tremella soup containing a lot of nitrite, nitrite will naturally enter the blood and oxidize hemoglobin in the blood into methemoglobin. In this way, tremella fuciformis loses its oxygen-carrying ability, making the human body lack normal hematopoietic function, and the required iron will be reduced, which will lead to a series of symptoms such as anemia.
