The purine content of different types of fungus varies from 38~166mg/100g, which is relatively not low. Common edible fungus can be divided into dry fungus, soaked fungus, dry sea fungus, its purine content of 166mg/100g, 38mg/100g, 90mg/100g. According to the purine content per 100 grams of food, “Modern Clinical Nutrition (Second Edition)” will be divided into four levels of food, 4 classes: purine content less than 30 mg; 3 classes: purine content less than 75 mg; 2 classes: purine content 75 mg ~ 150 mg; 1 class: purine content 150 mg ~ 1000 mg. Therefore, the purine content of fungus is between category 3 and category 1, which is relatively not low. Life, should be moderate intake of fungus, in order to prevent the intake of excessive purine, especially hyperuricemia and gout patients, should pay more attention to the intake of purine food, so as not to adversely affect the control of the disease.
